INSTRUCTION MANUAL
Air Auto Shut-Off Straight Screwdrivers
This product is designed for installing and removing threadedfasteners in wood, metal,
and plastic. The use of spare parts/accessories other than those originally supplied by
the manufacturer may result in a drop in performance and/or increased
maintenance/noise level/vibrations, and as the result, the full cancellation of the
manufacturer’s liability. No other use is permitted. For professional use only.
Air Supply Requirements
1. Supply tool with 90 PSI (6.3 KG/CM2) of clean, dry air. Higher pressure drastically
reduces toollife.
2. Connect the tool to the airline using pipe, hose, and fitting sizes shown in the diagram
below.
Lubrication
1. Use an air line lubricator with SAE #10 oil, adjustedtotwo (2) drops per minute.
If an air line lubricator cannot be used, add air motor oil to the inlet once a day.
2. For gearing and clutch, use Shell-grade grease containingmolybdenum.
3. Grease clutches every 12,000 screws.
Torque Adjustment
Shut Off Clutch: Grip the tool around the handle and press the tool into the fixing
which is to be tightened. The motor will start and tighten the fixing to the required
torque set by adjusting the tensions on the clutch spring. At this point, the internal drive
is disengaged and the air to the motor cut off.

Operating Procedures
1. Make sure the air in airline is clean and dry.
2. Make sure the tool is connected correctly with the air compressor.
3. Install a bit (as illustrated below). Before using, do check the bit being installed in the
tool correctly.
4. Torque Adjustment: Take off the torque cover and turn the torque adjustment ring
clockwise to increase the torque. Turn the torque adjustment ring counter-clockwise
to reduce the torque. When the torque is set up, put the torque cover back and
fasten it tightly to avoid changing the set-up accidentally. (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. Push to start: Push the tool to activate the motor.
7. Suggestion: Correct / Re-set torques before operation on a daily basis.
8. If not usedfor a long time, re-set the tool to the lowest torque.
