Keep your hair, clothing and gloves away from moving parts as they may get
caught.
•Keep children and bystanders away while operating a power tool as distractions
can cause the operator to lose control.
•Screws, nuts and bolts that have been tightened to a specific torque, should be
tightened with a torque wrench once the tyres have been fitted in place.
•If you are in doubt of correct torque stipulated for your vehicle, consult your car
manufacturer and/or vehicle manual specifications.

1. Park vehicle in a safe outside location away from moving traffic. Always set the vehicle
parking brake and block the wheels so the vehicle will not move while the impact
wrench is in use.
2. If you take off the battery and insert the 12V DC part to the device. Plug into your 12V
accessory socket.
3. Pick an impact socket that will fit the wheel lug nut. Press the socket onto the
driveshaft. Never use sockets that are not specifically designed for use with impact
wrenches.
4. Place a jack under the jacking point for the wheel to be removed and raise the vehicle.
5. Support the vehicle by placing jack stands at locations recommended by the vehicle
manufacturer.
6. Set the directional lever to “REV” and carefully loosen the lug nuts. Remove in the
order recommended by the manufacturer.

Warning!Do not get under the vehicle without jack stands. Jacks are not designed to
maintain heavy loads for long periods of time.
1. Lift wheel back into place.
2. Slide lug nuts onto the wheel bolts in the order recommended by the lug nut
manufacturer.
3. Set the directional lever to “FWD” and tighten the lug nuts by impact wrench. Keep
pressing the switch, then the device continuous FWD, until it stops working
automatically and the torque data will show as 000 at same time.
4. Use a torque wrench to check that the lug nuts are tightened enough as per the
manufacturer’s recommendations.
5. Remove jack stands. Carefully lower the vehicle and remove the jack. Unplug the
impact wrench and store.
Important:
It is highly recommended to use a torque wrench after use of the impact
wrench to correctly and safely set the wheel nut.
