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.
