Operating Instructions
1. Operation
The tool features an air regulator (at the top back of the tool) allowing you to vary the
amount of torque exerted on the nut or bolt you are working on. Setting
0
is the
lowest setting and Setting
5
is the highest setting and provides the biggest torque
and speed.
2. Loosening
-
Step 1: Attach the correct size socket to the anvil.
-
Step 2: Set the compressor’s pressure regulator to 90PSI. Do not set the
compressor’s outlet regulator above 90PSI.
-
Step 3: Connect the tool to the air compressor’s hose. If leakage is detected,
disconnect the air hose and fix it correct before use.
-
Step 4: Place the socket over the nut to loosen.
-
Step 5: Grip the tool firmly. Press the REVERSE Valve forward at the top back of
the tool. Press the trigger to start the tool.
(Caution: Make sure the nut or bolt can withstand the impact wrench’s working torque.)
* Note:
-
If the tool cannot loosen the nut, DO NOT raise the outlet pressure of the air
compressor.
-
If the tool’s air regulator is set in a low setting, you may raise the setting and try
again. If the tool’s air regulator is already set on
5
setting, do not continue
attempts to loosen the nut with the tool. Use other appropriate tools and methods
To loosen the nut.
-
When the nut is removed, stop the tool by releasing the trigger and remove the
tool from the nut. Remove the nut from the socket if needed.
3. Tightening
(The working torque of the impact wrench is 585 feet/lbs. Make sure that the nut or
bolt you are using the tool to tighten can withstand the rated torque.)
- Step 1: Tighten the nut as far as you can by hand.
- Step 2: Place the socket on the nut. Press the REVERSE Valve backward at the top
back of the tool. Press the trigger to start the tool.
* Note:
- If the tool stalls while tightening, DO NOT raise the outlet pressure of the air
compressor above 90PSI.
- If the tool’s air regulator is set on a low setting, it may be raised and try again. If the
nut will not tighten at the maximum setting, do not continue attempts to tighten the
nut. Use other appropriate tools and methods to tighten the nut.
- When the nut has been tightened, remove the tool and socket. Do not over-tighten.
- If available, check the recommended torque specifications for the nut. You should
use a torque wrench to torque the nut after using the impact wrench.

Air Supply
(please refer to the diagram below)
1. Make sure that the air compressor being used for the air tool operation supplies the
correct output (CFM).
2. Turn the throttle in the
off
position when connecting the tool to the air supply.
3. Use normal 90psi (or ranging from 6.0 to 8.0kg.) air pressure while running the tool.
High pressure and unclean air will shorten the tool’s life due to faster wear and also
may create a hazardous situation.
4. Drain the air tank daily. Water in the air line may enter the tool and damage the tool
mechanism at the operation.
5. Clean the air inlet filter cartridge weekly. The recommended hook-up procedure can
be viewed in the diagram below.
6. Line pressure should be increased accordingly to make up for extra long air hoses
(usually over 8 meters). The minimum hose diameter should be 1/4
I.D. and the
fittings should have the same inside dimensions. But usually a 3/8
I.D. air hose is
recommended for air supply to get the best function of air tool operation.
7. Use proper hoses and fittings. We do not suggest connecting quick change couplings
directly to the tool since they may cause failure due to vibration. Instead, add a
leader hose and connect coupling between air supply and hose whip.
8. Keep hoses away from the heat, oil and sharp edges. Check hoses for wear before
