PREPARING WRENCH FOR USE

3.1. Air Supply
Recommended hook-up procedure is shown in fig 1.
3.1.1. Ensure wrench air valve (or trigger) is in the "off" position (i.e. released) before connecting to
the air supply.
3.1.2. You will require an air pressure of 90psi, and an air flow according to specification.
3.1.3.  WARNING! Ensure the air supply is clean and does not exceed 90 psi while operating the
wrench. Too high an air pressure and unclean air will shorten the product life due to
excessive wear, and may be dangerous causing damage and/or personal injury.
3.1.4. Drain the compressor air tank daily. Water in the air line will damage the wrench.
3.1.5. Clean air inlet filter weekly. Line pressure should be increased to compensate for unusually
long air hoses (over 8 metres). The minimum hose diameter should be 1/4" I.D. and fittings
must have the same inside dimensions.
3.1.6 . Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain
that all connections are secure.
3.2. Couplings.
Vibration may cause failure if a quick change coupling is connected directly to the wrench.
To overcome this, connect a leader hose to the wrench. A quick change coupling may then be used
to connect the leader hose to the air line recoil hose. See fig 1 & 2.

4. OPERATING INSTRUCTIONS

WARNING! Ensure you read, understand and apply safety instructions before use.

4.1. Only use impact sockets which are specifically designed for use with a impact wrench.
DO NOT use worn or damaged sockets.
4.2. Connect the wrench to the air hose as in chapter 3.
4.3. Place the socket over the subject nut and depress the trigger to operate the wrench.
4.4. To change direction, push the button above the handle. Direction of "R" for reverse and
"F" for forward
4.5. The flow of air may be regulated by adjusting flow valve at the base of the handle.
DO NOT use any additional force upon the wrench in order to loosen/tighten a fixing.

DO NOT allow wrench to free run for an extended period of time as this will shorten bearing life.
