1. Make sure the air in air line is clean and dry.
2. There are three air-inlets on the tool. Depending on different usage, choose one inlet to
connect correctly with the air compressor. Screw up the other two air-inlets separately
with screw caps.
3. Install a bit (as illustrated below). Before using, do check the bit being installed on the
tool correctly.
4. Torque Adjustment: Take off the torque cover and turn the torque adjustment ring right
(clockwise) to increase
(counter-clockwise) to reduce the torque. After setting up the torque, put torque cover
back and fasten it tightly to avoid changing set-up accidently. (as illustrated below)
5. Right/Left Indication: Turn right (clockwise) the switch (marked "R") for tightening screws.
Turn left (counter-clockwise) the switch (marked "L") for loosening screws.
6. Two ways to operate:
A. Push + Pull The Trigger to Start: Set the bit aiming the screw. Push down the tool
steadily and pull the trigger to activate the motor. When the required torque is reached,
the motor will shut off automatically. Either releasing the trigger or take the tool away
from the fixing will stop the motor. (Dual security design)
B. Push to Start: Press the trigger and push the "Locking" switch to the right to lock the
trigger. Push down the tool steadily to activate the motor. The operation can be repeated
without pulling trigger constantly. When the required torque is reached, the motor will
shut off automatically.
