INSTRUCTIONS
Always wear safety goggles and gloves.
1. If removing wheels from a vehicle, block the wheels and jack the car
as instructed in the owner’s manual.
2. In other applications, be ready for parts shifting when the fastener
is removed.
3. Install the correct impact socket on the tool. Only use impact rated
sockets.
4. Select the correct rotation direction using the button above the
trigger switch.
5. Slide the fully charged battery pack onto the base of the handle. The
tool will operate at peak power with a fully charged battery pack.
6. Place the socket onto the fastener to be removed/tightened.
7. Hold the impact wrench with both hands and squeeze the trigger to
start the tool. The tool is variable speed so the harder you squeeze
the higher the speed.
8. When removing nuts, always squeeze the trigger fully so the tool
operates at its maximum speed to generate maximum torque.
9. If a fastener to be removed is “frozen” and will not loosen after
15 seconds of operation, reverse the impact wrench rotation and
tighten the fastener for 5 seconds to break it loose then change the
rotation direction again to remove the fastener.
10. When tightening fasteners, do not let the tool “rattle” for more than
2-3 seconds. This may overtighten the fastener.
11. Always check tightened fasteners with a torque wrench
recommended by the manufacturer to ensure the correct torque has
been applied. Particularly when tightening wheel nuts.
CHARGE THE BATTERY
NOTE: A discharged battery pack will be fully charged in approximately
two hours. Remove the battery pack from the tool when not in use.
WARNING
Always charge the battery pack indoors in a well-ventilated area. The
charger must never be subjected to wet conditions.
