The oil leak is likely from the automatic chain oiling system. Diagnosis follows a specific checklist.
- Confirm the saw is stored on a level surface. Tipping can cause oil to seep from the oil tank vent.
- Check the oil tank cap seal for damage or debris. A compromised seal is a primary leak source.
- Inspect the oil feed line from the tank to the pump and the outlet near the bar for cracks or disconnections.
IF THAT DIDN'T WORK: The oil pump itself may be faulty or the tank vent may be blocked, causing pressure to force oil out. Running the saw without the bar and chain to observe the oil output port can help isolate the leak location.
HEADS UP: Always empty the oil tank for long-term storage. Use only recommended bar and chain oil to maintain pump function.
