Parts for Poulan ES400: Chain Saw Parts

This authentic OEM part is a replacement momentary switch meant for a chainsaw or edge trimmer. Also known as a kill switch, a momentary switch acts as a safety measure to immediately shut off the appliance's motor. If the user begins to lose control of the appliance, they can simply hit the momentary switch and the engine will disengage even if it is not currently in the off position. This helps to prevent accidents and bodily harm. When engaged, the engine requires a five second waiting period before it can restart. Over time and through repeated use, switches can naturally become worn out. They may also be damaged if knocked against something hard on accident. Replacing this switch will require a screwdriver to access the switch located in the handle of the appliance. Once accessed, the switch can easily be replaced by detaching the wires and inserting the new part. Be sure to follow the user's manual as this process will vary depending on the appliance. This part is sourced directly from its original manufacturer and will work with Poulan and Weed Eater appliances. This part ships individually.

This is a replacement oil cap for a variety of small gasoline-powered tools they build. These devices include power saws, chainsaws, trimmers, and pruners. The oil cap is tethered to the oil tank, granting easy access to the engine oil for filling or replacement while preventing outside contaminants from getting into the oil basin and, thus, the crankcase. While the cap is not a moving part, it is one of the most exposed pieces of this work equipment. As such it collides with multiple heavy objects such as other tools, trees, cement structures, and truck beds. This type of wear and tear can cause the interior threads of the cap to warp so that the cap cannot be closed tightly. The cap can also be damaged so that it leaks. For safety reasons as well as for the proper operating condition of the equipment, a damaged oil cap should be replaced immediately.

With this genuine OEM product from the original manufacturer, quickly and easily swap out the oil cap before anything can fall into the tank. Just remove the broken cap, feed the blocker into the tank, and screw the new cap on. Compatible with string trimmers and chainsaws made by Craftsman, Poulan, and Poulan Pro. Sold individually.
