1-Inch High Torque Impact Wrench Operator's Manual 7
Always use clean dry air. Excessive moisture and dirt will greatly reduce the life of any
air motor. We recommend the installation of an in-line filter-regulator-lubricator as close
to the tool as possible.
Be sure all hoses and fittings are the correct size and tightly secured.
Designed to operate on 90 PSIG, lower pressure (below
90 PSIG) will reduce performance of the tool while higher air
pressure (over 90 PSIG) raises the performance of the tool
beyond its rated capacity and could cause serious damage
to tool and user.
