20 in. and 16 in. 45cc Heavy Duty Gas Chainsaw Combo
Home Depot Online
I bought a 20 in. and 16 in. 45cc Heavy Duty Gas Chainsaw Combo from Home Depot online. This item is manufactured by QV Tools. The muffler got red hot and started the plastic housing on fire. I tried to blow out the flames but I was only making things worse. QV Tools should have put fire retardant in the plastic. The piece of trash burnt to a crisp.

Report No. 20180620-0797B-2147387257

Comments: [REDACTED] apparently was the purchaser of the chainsaw at issue, according to the information provided by CPSC and the information on QV Tools ("QVT") Packing List. Unfortunately, the chainsaw in question was not returned to QVT so that we could conduct an inspection/failure analysis on this particular chainsaw. The incident reported by [REDACTED] is the first and only notification QVT has received that one of its chainsaws has caught on fire. In order to try to understand what happened to the chainsaw, QVT has taken steps to identify a particular failure, but has not been able to identify what caused the fire, though QVT has several theories of what took place that could have caused the fire, as set out below.
Initially, [REDACTED] purchased the chain saw on or about May 3, 2018 with a shipping date of May 4, 2018, as shown on the packing slip mentioned above. Over the next forty-five (45) days or so, [REDACTED] purchased two additional 20-inch chains for the saw in addition to one additional 20-inch bar for the saw, as set forth on QVT's packing lists. QVT assumes that [REDACTED] had worn out two chains and a bar by the time of the fire, which we understand took place on June 20, 2018. To our knowledge, no other user of this model chainsaw has worn out either a chain (let alone two) or a bar in such a short length of time. We therefore conclude that [REDACTED] was utilizing this chainsaw at a very high rate.
As with any type of tool, it is important to maintain the tool in good working condition. The manual for the chainsaw shows areas where it is important to keep wood chips and/or saw dust from accumulating. If wood chips and/or saw dust accumulated in the areas shown in the photos in the manual and not cleaned out during operation, especially when it appears that the chainsaw was being used so extensively, such a condition could lead to a seriously overheating engine which may have resulted in the fire.
Another condition that could have led to the fire is a lack of oil. This chainsaw uses a 2 stroke engine and uses a gas and oil mixture of 40 parts gas to 1 part oil. We have no way of knowing if the correct mixture was used. The oil is used for lubrication and cooling. If not enough oil was used, this can lead to more friction and heat.
Another condition that could have occurred had to do with the chain itself. If the chain was not receiving enough oil to keep it lubricated, the engine would have had to work harder in order to keep the chain moving, thus resulting in engine overheating and possible premature wear to the chain and/or bar, which appeared to have occurred, based on the number of chains and the bar that was ordered shortly after the chainsaw was purchased. If the engine were already running hotter because of a chain not being lubricated properly, a reduced amount of wood chips and dust caught in the cylinder and/or exhaust vents could have substantially increased the chances of a fire.

Finally, it appears from the photos that were submitted to CPSC by [REDACTED] that some type of tape had been wrapped around a portion of the body of the chainsaw. A portion of this tape was positioned over the cap to the fuel tank. QVT cannot identify any reason that tape would be placed over the cap on the gas tank unless the cap had been broken. This could have allowed the gas/oil mixture to splash out and possible ignite. QVT cannot identify any other reason tape would have been wrapped around the body of the chainsaw in this manner except to keep the cap in place.
After considering the above information, along with our testing of the same model chainsaw that [REDACTED] purchased, we believe that a fire may have been inadvertently caused by the operator. We have sold several thousand chainsaws like this one and have never been informed that a single fire started while using the chainsaw in the manner it was designed to be used. Thus, we do not believe that either the design of the chainsaw or the use instructions were to blame.

I certify that I have reviewed the Report and the Comment, and that the information contained in the Comment is true and accurate to the best of the Manufacturer/Importer's knowledge, information and belief.
