Ans: During the usage of a chainsaw, we always keep operational safety guides in our minds. A major safety rule should maintain during the period of fueling the tank. Following are the fuel safety guidelines: »  Never refuel the tank while the engine is running. »  Make sure that the fueling work is happening with the properly ventilated environment. »  Don’t start the chainsaw beside the refuelling point. » Wipe the spoiled oil/fuel on the machine before the start
