SETTING THE POWER REGULATOR

Impact wrenches are not torque control devices.
Fasteners with specific torque requirements must be
checked with suitable torque measuring devices after
installation with an impact wrench.
Models AW434C and AW434C–2 Impact Wrenches
incorporate a power regulator into the reverse mechanism
that allows the operator to have either full power output in
one direction and reduced power output in the other
direction or full power output in both directions. To adjust
the power, proceed as follows:
For full power in both directions, rotate the reverse
valve until the notch on each end of the reverse valve
aligns with the Letter H on each side of the housing.
The Letters H thru L on the
housing are only for reference
and DO NOT denote a specific
power output. L designates
the lowest power output while
H denotes the highest.

protection when operating
this tool.
