Overloading
If the tool is overloaded for any reason that causes
excessive heating of switch or battery, the internal
electronics will cause the tool to stop working. This is a
safety feature that will help to prevent overheating of the
tool. Release the trigger to resume operation.
— Battery over temperature – indicated by all four
LED lights flashing on the battery. This means
the internal temperature of the battery is too
high, and it will stop operation to prolong battery
and tool life. The lights will continue to flash for
four (4) minutes after each trigger pull until the
temperature lowers to an acceptable level. Fan
cooling can be used to speed battery or tool
cooling. Note: The electronics have been tuned
to get optimal performance /capacity from the
battery prior to reaching the temperature limit.
When this condition occurs, usually the battery
will be very close to needing recharging.
— Tool over temperature – indicated by the
illumination LED flashing. When the tool is used
under heavy load continuously, the internal
temperature of the switch may be reached, and
the tool will temporarily stop working. Allow the
tool to air cool to resume operation.
— Tool current limit exceeded – indicated by the
illumination LED flashing and tool stopping
operation while the trigger is fully depressed.
When the tool is used continuously in heavy
duty application, the current limit may be
reached, causing shut-down of the tool power.
Tool operation can be resumed immediately
after releasing the trigger.
Forward/Reverse Switch
The forward/reverse switch determines the rotating
direction of the anvil, either clockwise or
counterclockwise.

Figure 2: Forward/Reverse Switch
A – Depress switch for reverse or
counterclockwise rotation.
B – Release switch for forward or clockwise
rotation.
To change the direction of anvil rotation:
1. Be sure the impact wrench is stopped and not
operating.
2. The position of the forward/reverse switch
determines the direction of the anvil rotation. Switch
positions, when tool is positioned as above, are:
— Forward (B above), the anvil rotates clockwise,
— Reverse (A above), the anvil rotates
counterclockwise.
3. The switch must be in either the forward or the
reverse position to operate. Center position locks the
switch off.
Trigger
Depress the trigger to rotate the anvil. The lever must be
in a forward or reverse position to operate. The trigger
can be locked in the OFF position. Locking the trigger in
the OFF position helps to reduce the possibility of
accidental starting the impact wrench when not in use.
Place the lever in the center position to lock the trigger.
Lock the trigger when not in use.
Battery Charging
1. Insert the power cord plug into the socket of the charger.
2. Plug the other end of cord plug into power source
outlet.
3. Insert battery pack in the charger. Position the battery
pack so that the battery sits flush with the top of the
charger.
— The green light will start flashing. This indicates
the charger is charging the battery pack.
4. The fuel gauge on the battery pack will display the
charge percentage % value status. Standard fast
charging time is 45 minutes.
— When the battery is 25% charged, one light will
be solid green.
5. When the fast charge is complete all (4) lights on the
battery pack will be solid green indicating battery is fully
charged and charger will indicate solid green light.
6. If the LED on the right hand side is flashing a yellow light
then the battery pack is either hot or cold. The charger
will not fast charge the battery if it is too hot or cold. The
charger goes into a fast charge mode when the battery
temperature is between 32°F (0°C) and 113°F (45°C).
7. If the LED on the right hand side is flashing a red light,
the battery pack is faulty and the charger will not charge
the battery.
8. When the fast charge is complete, battery voltage is
detected by the charger and it automatically turns off to
prevent an over-charge and all four lights on the battery
fuel gage will be on and charger will indicate solid green
light
9. The charger has one USB port, its output current is 0.5 A
and output voltage is 5 VDC. Do not connect to an
appliance requiring over 0.5 A.
