Operation
The impact wrench must be
properly lubricated before operation. See
“Lubrication” section.
Figure 1
1. Remove protective cap from air inlet (Figure
1). If an in-line oiler is not being used, add 4
or 5 drops of air tool oil (not included) into the
air inlet.
2. Blow out air line to remove any dirt or
moisture, then connect air supply hose to
tool. Set air pressure to 90 psi.
IMPORTANT: Connecting a quick-change
coupling directly to the tool is not
recommended, as vibration may cause the
connection to fail. Instead, add a leader hose
and install any quick-change couplings
farther down the line.
3. Push drive socket (not included) onto anvil
until it clicks into position.
4. Select rotation direction: “F” for forward, “R”
for reverse.
5. Set regulator switch to desired speed setting.
Make sure nut or bolt can
withstand rated torque of impact wrench.
To loosen nut or bolt:
1. Select reverse rotation.
2. Place socket over nut, hold grip firmly, and
place other hand over top of housing. Gently
squeeze trigger.
Important: If tool cannot loosen nut, DO
NOT raise air pressure above 90 psi. If tool’s
air regulator is in low setting, raise setting
and retry. If tool’s regulator is already at
maximum, do not continue attempts to
loosen nut with this impact wrench. Use
other methods or tools to loosen nut.
3. Release trigger to stop impact wrench.
To tighten nut or bolt:
1. Install nut as far as possible by hand.
2. Select forward rotation.
3. Place socket over nut, hold grip firmly, and
place other hand over top of housing. Gently
squeeze trigger.
Important: If tool stalls while tightening, DO
NOT raise air pressure above 90 psi. If tools’
air regulator is in low setting, raise setting
and retry. If nut will not tighten on
maximum setting, do not continue
attempts to tighten nut with this impact
wrench. Use other methods or tools to
tighten nut.
4. Release trigger to stop impact wrench.
NOTE: Do not overtighten. Fasteners with critical
torque settings should be fully tightened with a
torque wrench.
