Operation - Husky H4490 Use And Care Manual

Operation

1
Operating the impact wrench
□ This Impact Wrench is designed to operate on 90 PSIG.
Lower pressure (below 90 PSIG) will reduce performance
of the tool. Higher air pressure (over 90 PSIG) raises the
performance of the tool beyond its rated capacity and
could cause serious damage to the tool and the user.
3
Changing the output torque level
□ This tool features a power management switch. This tool
operates in the maximum power in the Reverse position
and has three steps in the Forward position.
□ Turn the regulator until the desired output torque level is
achieved. The position with the smallest circle has the
least amount of power and the position with the largest
circle has the most amount of power. The settings on
the regulator are only for reference and do not denote a
specific power output.
2
Changing the output torque direction
□ This tool features a reverse switch to change the
output torque direction to tighten (assemble) or loosen
(disassemble) the bolt or fastener.
□ Control the output torque direction by pushing the reverse
switch button to the F (Forward) or R (Reverse) position to
change the direction.
4
Tightening/loosening the bolts or
fasteners
□ Place the rotation push button located above the trigger of
the impact wrench to the correct direction. Push the button
forward for the Forward position and push the button back
for the Reverse position.
□ To control power in either the forward direction or the
reverse direction, adjust the regulator knob located at the
foot of the handle of the impact wrench.
□ Fit the correct size socket to the anvil of the impact
wrench.
□ Hold the impact wrench with one hand and place the
socket onto the nut/bolt to be tightened or removed. Press
the trigger and stop the operation once the nut/bolt is
removed or tightened.
WARNING: Once a bolt or fastener is seated, impacting for
longer than five (5) seconds will cause excessive wear and
possible damage to the impact mechanism. If it takes longer
to tighten or loosen your bolt or fastener, we recommend the
use of a larger sized impact wrench.
