3. Using The Power Management System
Air impact wrenches are not torque control devices. Fasteners with specific torque requirements must be
checked with suitable torque measuring devices after installation with an air wrench.
POWER MANAGEMENT SYSTEM
The impact wrench incorporates a Power Management System that allows the operator to select 3 power
output settings. These settings range from minimum power output through maximum power output.
The 3 power setting indicators of increasing size on the rear of the housing indicate increasing power output
levels, are for reference only and DO NOT denote a specific power output. The “1” power setting indicator
designates minimum power output, the “2” power setting indicators denote medium power outputs and the “3”
power setting indicator denotes maximum power output.
The power output can be further reduced in forward or reverse by using the variable throttle. Air supply
systems which do not deliver adequate air pressure can affect power output at all settings.
