Leaking major oil
For model number DCS540
PartSelect logo
Hello Jay and thank you for writing. It's easy to do and it is amazing how many times this simple oversight is the cause of chain oil leaks. An overfilled reservoir can often leak oil when the saw is turned on. If the oil is running out via the delivery line to the bar then there is a chance that the tank vent PS9866666 is plugged up or defective. We hope this helps. Please contact us anytime if you require further assistance.

Keep searches simple. Use keywords, e.g. "leaking", "pump", "broken" or "fit".
Gas leaking from the side of the body when the fuel fill inlet was facing up. Determined that the fuel was leaking around the fuel line where it came out of the tank
Removed the handle, carburetor, and plastic piece under the carburetor to access the fuel line where it comes out of the tank.
Fished the fuel filter out the gas fill port and removed the fuel filter.
Ended up cutting the old fuel line where it enters the tank.
Removed the old fuel line pieces out from the top and bottom.
Was having a tough time pressing the new line into the hole at the top of the tank so I added a dab of grease and it slipped right in.
Used a piece of thin wire to fish the new fuel line to the gas filler port in order to reinstall the gas filter.
Will install a new gas filter the next time the saw runs out of gas.
