Air Auto Shut-Off Pistol Screwdriver

This product is designed for installing and removing threaded fasteners 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. As a result, the full cancellation of the manufacturer’s liability. No other

use is permitted. Professional use only.

Air Supply Requirements

1. Supply tool with 6.35 KG/CM2(90 PSI) clean and dry air. Too much pressure drastically

reduces the tool life.

2. Connect the tool to air line using pipe, hose and fitting sizes shown in the diagram below.

Lubrication

1. Use an air line lubricator with SAE #10 oil. Adjustedto two (2) drops per minute. If an air

line lubricator is not available, 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 tension on the clutch spring. At this point, the internal drive is disengaged and

the air to the motor cut off.

Operating Procedures

Air-inlet

Right/Left Switch

Torque Cover

Bit Retainer Sleeve

Trigger

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 the torque. Turn the torque adjustment ring left

(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.

7. Suggestion: Correct / Re-set torques before operation on a daily basis.

8. If the tool is not to be used for a long time, re-set the torque to the lowest.
