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 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 air tank daily. Water in the air line will damage the wrench.
3.1.5. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig 1.
3.1.6. 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.
3.1.7. 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 figs.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 ratchet wrench.
4.2.
Connect the wrench to the air hose as indicated in section 3.
4.3.
Set the integral air regulator to one of the four positions indicated (see fig.3).
4.4.
Place the socket over the subject nut and depress the trigger to operate the wrench.
4.5.
To change wrench direction turn the switch on the head of the wrench (see fig.3).
DO NOT use any additional force upon the wrench in order to remove a nut.
DO NOT allow wrench to free run for an extended period of time as this will shorten its life.
4.6.
The direction of the air flow from the exhaust holes in the central sleeve can be altered by
rotating the whole sleeve to a suitable position. The sleeve can be rotated continuously
through 360° (see fig.3).
