5. Remove the screw and hold 

the oil port hole over a 

container to allow excess oil 

to drain.

6. If the oil is dirty, repeat the 

procedure above until the oil 

comes out clear. Install the 

screw and tighten. The residual 

oil remaining in the impact 

mechanism chamber is all that is needed for proper 

lubrication

Air supply

Air supply MUST be greater than air requirement of the 

tool. Recommended air compressor is 3/4HP tank for 

intermittent use; 1.5HP or larger for heavier duty use

Storage

The impact wrench must be lubricated before storing. 

Follow the air motor lubrication instructions. Only run for 

3 seconds instead of 20 seconds because more oil needs to 

remain in the tool when storing.

Adjustable speed control

This impact wrench is equipped 

with a regulator for adjustable 

speed control (4). This switch is 

located at the rear of the tool. 

The impact wrench should NEVER 

be used to set torque. Use a 

torque wrench to set the torque.
To remove nuts, set the regulator to the maximum setting. 

To install nuts, set the regulator to the minimum to 

medium setting. Do not over-tighten the nuts.
Forward and reverse directions are controlled by rotating 

the speed control knob noted.

General inspection 

1. Regularly check that all the fixing screws are tight. 
2. The supply cord of the compressor should be checked 

frequently for damage. If damaged, have the cordset 

replaced by an authorised service facility to avoid a 

hazard. 

Cleaning 

1. Keep the tool’s air vents unclogged and clean at all 

times. 

2. Remove dust and dirt regularly. Cleaning is best done 

with a soft brush or a rag. 

3. Re-lubricate all moving parts at regular intervals. 
4. If the body of the air tool needs cleaning, wipe it with 

a soft damp cloth. A mild detergent can be used but 

nothing like alcohol, petrol or other cleaning agent. 

5. Never use caustic agents to clean plastic parts. 

CAUTION:

 Water must never come into contact with the tool. 

Repairs 

1. Only an authorised service centre should carry out 

repairs on air tools.
