Echo P021001980 Auto Oiler Pump Chainsaw Oem

Product Description

The ECHO P021001980 is a genuine OEM auto oiler pump designed to deliver automatic bar and chain lubrication in ECHO chainsaw models. The oiler pump meters oil flow to the guide bar and chain during cutting operation, reducing friction and heat buildup that would otherwise accelerate wear on the cutting components. At 0.11 pounds and measuring approximately 0.98 inches on each side, this compact pump is a direct factory replacement. Installation is performed by a qualified small-engine technician or experienced outdoor power equipment service pro.

This auto oiler pump fits ECHO chainsaws including the CS330MX4, CS330T, CS360T, CS370, and CS400 models. It is suited for residential and light commercial chainsaw applications where reliable chain lubrication is critical to safe cutting performance. Replacing a worn or failed oiler pump restores proper oil delivery and protects the bar and chain from premature wear during operation.
