The product, in the report: 2012 model MS181C STIHL gas powered chain saw

I was cutting some small trees and branches near my home with my STIHL chain saw. It had been working fine with no problems and no sign or indication that it might break or fail. I put it down for a bit then picked it up again and pulled the starter card to start it and the entire starter rope recoil mechanism broke loose from the saw and slammed back into my face cutting my chin deeply. The cut bled profusely.

The product, in the report: Stihl MS271 Chainsaw

I recently purchased a Stihl MS271 chainsaw. Upon the first time starting it, the saw burned itself up. I thought it was a manufacturing defect so I took it to the local Stihl dealer and filed a warranty claim. My claim was denied due to “operating the saw with the chain brake on”. This was very frustrating to me to get the claim denied, but I am actually more concerned that Stihl’s official response to the Chain Brake safety feature is “don’t use it while running or you will burn up your chainsaw.”

The company’s comments, in its own words

(2/9/2022) STIHL, INC.: At STIHL Incorporated the safety and reliability of our products are top priorities. Component parts of any power tool can be damaged or require repair for different reasons. The MS 271 is equipped with a chain brake, which is a safety feature that is explained in the MS 271’s instruction manual. If the MS 271 is accelerated for a length of time while the chain brake is engaged, damage to the engine and component parts can result, which appears to have happened in this instance. Our Customer Service department discussed these points with the customer and we believe this matter has been resolved amicably.
If you are an experiencing an issue with your STIHL product, please stop using it immediately and take it to a STIHL dealer. STIHL appreciates your business, and we hope we can satisfy your future outdoor power equipment needs. If you would like to discuss this report further, please call us at 1-800-GO-STIHL.

The product, in the report: Stihl MS-461 gas chainsaw

My less than one year old Stihl MS-461 chainsaw spews gasoline when the fuel cap is opened. After running the chainsaw for 30 minutes I went to open the fuel cap. There was a loud sound and a geyser of fuel spewed out of the fuel tank and all over me and my equipment. This has happened four times now.

The company’s comments, in its own words

(1/19/2021) STIHL, INC.: At STIHL Incorporated we care about our customers, and the safety and reliability of our products are top priorities. It is well known that an expulsion of fuel, vapors and fumes, sometimes referred to as “fuel spray” or “geysering,” can occur anytime there is fuel, heat and pressure. When gasoline in a sealed container is heated by ambient temperatures, heat from an engine, or other sources, vapor pressure will increase inside the fuel container. If the container pressurizes, removing the fuel cap improperly, or without allowing the equipment to cool adequately, can allow fuel to be forcibly ejected from the container’s opening, much like what happens when the cap is opened too quickly on an overheated automobile radiator. This phenomenon is neither unique to STIHL products, nor is it limited to chain saws. U.S. Forest Service research and reports, for example, have included fuel geysering incidents with several different brands of chain saws, water pumps, ATVs, other gasoline-powered products, as well as portable fuel containers that have no engine, including fuel bottles and fuel cans. For more information about fuel tank pressurization and how to open the fuel tank of your STIHL product safely, please review the warnings and instructions contained in the Instruction Manual. STIHL Incorporated also has a public video with information about fuel geysering: https://www.youtube.com/watch?v=wjSczH0Yli8. Please feel free to call us at 1-800-GO-STIHL if you would like to discuss this further.

The product, in the report: Stihl MS391Chainsaw Model MS391

Stihl MS391 Fuel Geyser. Cold start of chainsaw with no issues. Shut it off and attempted to restart a warm saw. Had trouble starting and staying running. Running required feathering throttle to keep the saw at operating speeds. This was repeated multiple times without successfully getting the saw to run properly. Stopped saw and checked fuel condition. Upon removing the fuel cap, the gas was expelled at high velocity. Spray extended 2 to 3 feet and hit me directly in the face. Entire face and safety glasses were covered with fuel. I was able to wash off the fuel and the safety glasses protected my eyes. I was not hurt, but I consider this a near miss and dangerous.
I was running similar two stroke devices [REDACTED] and [REDACTED] chainsaw) with the same fuel that day without issue. This situation has been reported to Stihl and the saw submitted to the local dealer for review.

The product, in the report: Chainsaw: Stihl MS460 with tool less fuel cap.

[REDACTED]. Temp was approx. 82-85 degrees, RH was approx. 28, and elevation was approx. 1200-1400 feet. The crew had just been ordered to the top of a ridgeline to help contain some spot fires that were produced from a run to the top of the ridgeline and spotted over holding line. One of the saw teams started up their saw (Stihl MS460) and noticed that the saw ran sluggish and was not wrapping out as usual. The sawyer stepped back from the fires black edge and opened the cap to visually inspect the fuel tank when a fuel geyser happened. The tank was 3/4 full of fuel. The sawyer was sprayed in fuel on his nomex shirt, gloves, and his face. The sawyer was wearing [REDACTED] goggles at the time this happened and suffered fuel to the eyes. The sawyer was treated with eye flushing by the crew EMT and a CA-1 was also filled out and filed with SMIS as precautionary measure. The Sawyer did not suffer any injury and there was no fire as result of the fuel geyser. The previous week the crew had noticed that a few of the 5 gallon fuel cans provided by the cache were labeled 2013. The fuel provided by the cache were also marked 40:1 mix ratio as well.

The company’s comments, in its own words

(5/17/2017) STIHL, INC.: At STIHL Incorporated the safety and reliability of our products are top priorities. It is unfortunate that an equipment operator was injured.
It is well known that fuel can “spray” if the fuel tanks on many types of gasoline powered tools and equipment are allowed to over-pressurize and the fuel caps are removed improperly. The same is true of any type of closed container used to hold gasoline, including the fuel cans routinely used by the Forest Service. This incident resulted from a series of errors by the operator. He did not allow the fuel tank, which had been exposed to elevated temperatures from the fire, to cool adequately before opening it. He apparently did not open the cap slowly. He may have removed the fuel cap too close to an ignition source, although there is no indication of a fire in the report.
Motorists know to use caution when removing the cap of an overheated automobile radiator. Individuals using gasoline powered equipment in extreme conditions need to exercise similar caution. We understand that the Forest Service recently renewed its training efforts regarding fuel container pressurization, and we applaud those efforts as the best way to eliminate these types of incidents.
Please feel free to call us at 1-800-GO-STIHL if you would like to discuss this further.

The product, in the report: Professional model chainsaw and any other Stiihl saws with “flip type” caps.

Stihl chainsaw 362 has fuel cap which does not reliably seal fuel tank resulting in spilled fuel on operators leg (pants). Although annoying this could result in a fire if near an ignition source. i have had problems with these “flip style” caps in the past - on other Stihl models. This most recent saw had a cap that would not seal after many diliberate attampts to insert and close the mechanism carefully. The leakage resulting from these poorly performing fuel caps could result in an unessacary burn to the saw operator leg. A similar Stihl fuel cap has been the subject of a recall on other types of Sthil power equipment, chainsaws for some reason, were not included. These Sthil “flip type” fuel and oil caps are not reliably capable of preventing a fuel spill onto the operator and also into the environment. A saw fully fueled and left to sit on the ground could conceivably discharge the contents of the tank over - say - a lunch break. Problems with these caps have been ongoing for many years and are well know within the industry - a Google search of Stihl fuel caps returns some discussion of the shortcomings of this overly complex and fragile design. Screw type fuel caps have been successfully used for decades on many types of equipment requiring a fuel tank and a cap used for sealing the tank. The principles and utility of a screw cap are well understood. Common sense could lead one to believe that Sthil’s “flip type” caps have not proven themselves - to be able to be used correctly - as Stihl may assert - and or to reliably retain the contents of the fuel and oil tanks. A Gooogle search, today, of “Stihl fuel caps burns”- returned a report by the National Interagency Fire Center, of a wildland firefighter burned from gasoline soaked chaps. The report is - Subject: Stihl Chainsaw Fuel/Oil Caps Date 08/01/2014. The warning issued in this “Safety Warning Final” is a plausible occurrence given my experience with fuel leakage on my pants. So this issue is well know, over a period of many years and now one could presume at least one person injured .

(12/21/2015) STIHL, INC.: At STIHL Incorporated the safety and reliability of our products are top priorities. We would like to arrange to inspect your chain saw to determine the cause of your complaint, but have been unable to do so because to date you have not provided us your contact information. Any fuel cap on any manufacturer’s equipment can leak if it has been damaged or not been properly installed. We encourage you to immediately have your chain saw inspected by a local STIHL authorized dealer to see if the saw or cap has been damaged. If you have any questions about how to use the cap, please review your Instruction Manual. You also can call us at 1-800-GO-STIHL if you would like to discuss this further.

The company’s comments, in its own words

(6/23/2014) STIHL, INC.: At STIHL Incorporated, safety is a top priority, and we are sorry to hear that your gardener was injured while using a STIHL product.
The MS 192 TC is a professional-use chain saw powerhead. Like all STIHL chain saw powerheads, it is intended for two-handed operation. It is our understanding that you claim that the saw “caught” and “kicked,” contacting the operator’s left hand and resulting in an injury. As the Instruction Manual for the chain saw points out, reactive forces such as kickback may occur when the moving saw chain near the upper quadrant of the bar nose is suddenly stopped by contact with any solid object such as a log or branch or is pinched – possibly resulting in loss of control and serious personal injury. The Instruction Manual also makes clear that, in order to reduce the risk of loss of control, the saw should always be held with two hands, with the left hand on the front handle bar. In this position, it is impossible for a kickback to contact the operator’s left hand. It is, therefore, much more likely that the operator was improperly holding the saw with only one hand and may have improperly been holding a nearby branch with his left hand.
We were unsuccessful in our attempts to contact the operator of the chain saw at issue in this accident. We encourage him to contact STIHL directly at 1-800-GO-STIHL and press “2” for Technical Services. Learning more about this accident will help us determine what may have caused it. We thank you for calling this matter to our attention.
Sincerely,
STIHL Incorporated

The company’s comments, in its own words

(4/8/2013) STIHL, INC.: At STIHL Incorporated, safety is a top priority, and we are sorry to hear that fuel was leaking from your chain saw. We have been trying to contact you with respect to this report, but, so far, have not heard back from you. We would like to understand more about the incident and its causes. For instance, we cannot determine several important items from the description of the incident that was submitted. It is unclear what the cause of the fuel leakage was or its location. In addition, there is no record that, in the three-and-a-half years since your purchase, anyone ever brought the chain saw in for service, parts or repair.
A number of factors could have caused fuel to leak from the chain saw including poor maintenance, improper use or not installing the fuel cap properly. All fuel caps will leak if not properly installed. In addition, when transporting the chain saw, it must be properly secured to avoid fuel spillage. Please take your chain saw to your local STIHL servicing dealer and have it inspected. The chain saw fuel cap or fuel filler opening at issue could have been damaged and in need of repair or a fuel line could have been loose or the fuel tank could have developed a crack from having been dropped. The sooner you take the unit to your dealer, the sooner the cause of the leak can be determined and remedied.
For your information, you can find detailed instructions, guidance and cautions in your STIHL chain saw instruction manual including instructions on fueling your chain saw and properly opening and closing the fuel cap.
We very much appreciate your calling this matter to our attention. We hope that you will be able to provide some of the information that is missing from the initial report so that we can make a more informed assessment about what might have occurred. If you have any other questions or concerns about the operation, safety or performance of your STIHL chain saw or any other STIHL products, please contact us directly at 1-800-GO-STIHL and press “2” for Technical Services.

The product, in the report: Stihl Chain Saw Model # MS-290

An employee was starting a Stihl MS-290 chain saw. Once the saw was started the employee revved the engine twice and the saw exploded in the area of the fuel tank catching the saw on fire and the employees left leg (and chaps) on fire. The employee threw the chain saw to the ground and started rolling to put out the fire on his leg. He was assisted by another employee in the area and the fire dept. and medical services were called for assistance.
The employee was wearing the proper PPE (gloves, chaps, safety glasses, hearing protection).
After the incident was over the chain saw was inspected by the employees co-workers and the safety department.
The Stihl web site was researched and found that there was a “Fuel Cap” recall but the chain saw was not listed in the recall. The recall stated that the caps being replaced would have a molded letter “D” or lower on it and the new caps would have a “E” or higher on it. The caps on the saw involved in the incident (and one other saw of the same model) both had the letter “D” on the inside of the cap.
The Stihl phone number for the fuel cap recall was called and they were informed of the incident that had occurred with the saw and that a fuel cap with the letter “D” was on the saw at the time of the incident.
The Stihl representative stated that there were caps on other pieces of equipment that were similar to the recalled caps and that the cap could be replaced at no charge if the cap was taken to a local distributor.
Our concern was that there is a possibility that there are still defective caps on their equipment and that there could possibly be more incidents / injuries because of these caps.

The company’s comments, in its own words

(10/9/2012) STIHL, INC.: At STIHL Incorporated, safety is a top priority, and we are sorry to hear that your employee was involved in an accident while using a STIHL chain saw. We have been trying to contact you with respect to this report, but, so far, have not heard back from you. We would like to understand more about the accident and its causes. For instance, we cannot determine several important items from the description of the incident that was submitted and the accompanying pictures. From the photos it appears the fuel cap was not installed in the fuel filler opening at the time of this accident. This suggests that the fuel cap was never properly installed. Because no picture of the fuel cap was included, we cannot tell if it was damaged prior to the accident. It also would be beneficial to have information on the last time the machine had been refueled, since fuel could have been spilled on the chain saw and the operator at that time. Finally, because of the “richness” of the gasoline-to-air mix in the fuel tank, an “explosion” cannot take place inside the tank, so we would like to speak to the reporter to try to understand what he did observe.
While it is correct that STIHL voluntarily recalled certain products in cooperation with the CPSC on May 25, 2011, it was not as you indicate, due to “defective [fuel] caps.” Those products were recalled specifically because the levels of ethanol, aromatics or other additives in some gasoline can distort parts of the fuel cap, which sometimes makes the caps more difficult to install and/or remove. Your description of the incident, however, does not indicate that the operator had been experiencing problems installing or removing the fuel cap on the machine.
As STIHL makes it clear in its Instruction and Safety Manuals, it is important always to check for fuel leakage before and during usage of any gasoline powered tool and in the event of fuel or oil leakage not to start or run the engine until the leak is fixed. If fixing the leak involves anything more than properly reinstalling the cap, operators should take the equipment to a STIHL dealer for inspection and any necessary repairs.
We very much appreciate your calling this matter to our attention. We hope that you will be able to provide some of the information that is missing from the initial report so that we can make a more informed assessment about what might have occurred. If you have any other questions or concerns about the operation, safety or performance of your STIHL chain saw or any other STIHL products, please contact us directly at 1-800-GO-STIHL and press “2” for Technical Services.

The product, in the report: Stihl Chain saw with 16” bar, Orange, white, color, with tool-less gas and oil caps. Approximate purchase date of 2005

There is an existing recall from May 2011, on Stihl brand power equipment that use a faulty gas cap design that is a safety hazard. I was very disappointed to find that this recall does not cover their chainsaws which is this SAME cap design. I own a chainsaw made by Stihl and have no less than 5 times been soaked with fuel while using the saw and having the cap come off while in use. I have had my clothing and shoes soaked with not only gasoline/oil mixture, but also chain saw bar oil, which also has a resivoir that uses the same cap design. In my opinion Stihl needs to be pressured to include their saws in this recall, as they are just as much of a safety hazard as the other products included in the recall. Completely aside from the safety issue, they are also an environmental one as well. Chain saw bar oil has spilled from my saw on several occasions onto the soil. I took responsibility and properly cleaned up the spill as not to have my ground water which I drink from my private well contaminated.

The company’s comments, in its own words

(1/27/2012) STIHL, INC.: We appreciate you calling this matter to our attention. At STIHL Incorporated, safety is a top priority, and we are sorry to hear that you experienced fuel and oil leakage while operating your STIHL chain saw. Without additional information we cannot determine the exact reason for your problem. However the fact that you were having difficulty with both the oil and fuel filler caps on your chain saw suggests that the caps were not closed properly or could be damaged. With a seven-year-old machine, even normal wear and tear obviously can affect the performance of various components.
Per our Instruction and Safety Manuals, (which are available from any authorized STIHL dealer or downloadable at www.stihlusa.com) you should never start or run any STIHL product in the event of fuel leakage. Please stop using your chain saw immediately and take it to your nearest servicing STIHL dealer (www.stihldealer.net/locator), who will be able to correct the problems you identified and inspect your chain saw for any needed repairs or maintenance.
Please note that the STIHL products voluntarily recalled by STIHL in cooperation with the CPSC on May 25, 2011 (the “Recall”) were recalled because the levels of ethanol, aromatics or other additives in some gasolines at times made fuel caps more difficult to install or remove, and not, as you noted, due to a “faulty gas cap design.” For that reason, the Recall did not include oil filler caps, which are not exposed to ethanol or other fuel additives.
Again, thank you for calling this matter to our attention. If you have any other questions or concerns about the operation, safety or performance of your STIHL chain saw or any other STIHL products, please contact your local STIHL dealer or us directly at 1-800-GO-STIHL and press “2” for Technical Services.

(9/16/2011) STIHL, INC.: At STIHL Incorporated, safety is a top priority, and we are sorry to hear that your MS 270 chain saw, which you indicated was about 6 years old, was leaking fuel from the cap. We were glad to learn during our recent conversation with you that you recently received a replacement toolless fuel cap for the unit from your local STIHL dealer. We are pleased that you are no longer having difficulty installing and removing your replacement toolless fuel cap and also have not had any further incidents of fuel leakage.
The Instruction Manual for the MS 270, which can be downloaded from this webpage http://www.stihlusa.com/information/info_product2.html, contains fueling instructions and warnings about fuel leakage. In addition, the Instruction Manual provides instructions on how to properly open and close the toolless fuel cap. Take care not to spill fuel while fueling and do not overfill the tank. We would encourage anyone that does not understand any of the instructions in the Instruction Manual to contact their local STIHL dealer for clarification prior to operating the unit. If anyone is experiencing a fuel leak, they should immediately stop using it and take it to their STIHL dealer for an inspection and repair.
If you still have any questions or concerns about the operation, safety or performance of your MS 270 chain saw or any other STIHL products, please contact us directly at 1-800-GO-STIHL and press “2” for Technical Services. We thank you for calling this matter to our attention.

The company’s comments, in its own words

(9/15/2011) STIHL, INC.: At STIHL Incorporated, customer satisfaction and safety are top priorities. We are sorry to hear that you were experiencing problems operating your MS 290 chain saw. Our records indicate that this unit was purchased in April 2011 and was recently serviced by your local STIHL dealer. According to our records, the STIHL mechanic noticed that the torsion spring that is part of the Master Control Lever™ connecting the throttle trigger and the throttle interlock was bent. The mechanic determined that the torsion spring had been bent as the result of an improper starting procedure for the chain saw.
The Instruction Manual for the MS 290 (which can be downloaded here: http://www.stihlusa.com/information/info_product2.html) contains specific instructions on how to properly start its engine with the chain brake engaged. It outlines that when initially moving the Master Control Lever™ to either the cold start or warm start position, the operator must first press down the throttle trigger interlock and squeeze the throttle trigger at the same time. Also, after pulling the starter grip, if the engine begins to pop or fire, the Master Control Lever™ must be moved to the warm start position (if not already set there) before continuing to pull the starter cord. As soon as the engine starts to run, the operator must immediately depress the throttle trigger interlock and blip or squeeze the throttle trigger which causes the Master Control Lever™ to move to the “Run” position and returns the engine to its regular idling speed.
Forcing the Master Control Lever™ into the initial starting position described above, or into the Run position without first simultaneously depressing the throttle trigger interlock and throttle trigger will create excessive force on the torsion spring. Based on the mechanic’s inspection, he determined that the bent torsion spring resulted from the repeated forcing of the lever. Following the proper starting procedure should prevent this from re-occurring.
