For recommended hook-up, procedure is shown in fig.1 & 2
3.1. Air Supply.
3.1.1. Ensure wrench air valve (or trigger) is in the OFF position before connecting to the air
supply.
3.1.2. This wrench 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 90psi 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 compressor air inlet filter weekly.
3.1.6. Line pressure should be increased to compensate for unusually long air hoses (over 8
metres). The minimum hose diameter should be ¼” 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 fig 1 & 2.
3. PREPARING WRENCH FOR USE
4. OPERATING INSTRUCTIONS
WARNING! Ensure you read, understand and apply the safety instructions before use.
4.1. Only use impact sockets which are specifically designed for use with an impact wrench.
4.2. Connect the wrench to the air hose - see Section 3.
4.3. To undo a nut, turn the air regulator switch on the rear of the body to ‘R’, place the socket
over the subject nut and depress the trigger to operate the wrench.
4.4. To change drive direction to ‘F’ and regulate the flow of air, turn the air regulator switch
on the rear of the body, between 1-working torque and 3-ultimate torque (fig.3).
DO NOT use any additional force upon the wrench, in order to remove a nut.
DO NOT allow the wrench to free run for an extended period of time as this will shorten its life.
