描述

Quit guessing if your saw is performing at it's peak level. This simple tool makes testing your saws compression a snap. Tester has both imperial and metric scale that goes up to 300 psi. Has a side release valve for multiple tests also. Head accepts 14mm and 18mm plug holes, so it will work on most all chainsaws and other small gas engines made today. It's check valve is in the end of the hose and the release valve is on the gauge. Most chainsaws need a minimum of 110 psi to function properly. Though a chainsaw may start at less than a 110 psi reading, it will not perform at the optimum level.
