3. PREPARING WRENCH FOR USE
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. You will require an air pressure of 90psi, and an air flow according to specification.
3.1.3. WARNING! Ensure that the air supply is clean and does not exceed 90 psi whilst
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).

4.1. Only use impact sockets which are specifically designed for use with an impact wrench.
4.2. Connect the wrench to the air hose as in section 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 at the top of the handle. Direction of “R” for reverse and
“F” for forward
4.5. The flow of air may be regulated by adjusting the flow valve at the base of the handle.
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.
5. MAINTENANCE
WARNING!Disconnect the wrench from the air supply before changing accessories,
servicing or performing any maintenance.Replace or repair damaged parts. Use genuine
parts only. Non-authorised parts may be dangerous and will invalidate the warranty.
5.1. Lubricate the air wrench daily with a few drops of Sealey air tool oil dripped into the air inlet.
5.2. Check and top up the gearbox by removing grub screw located under the impact head.
5.3. Clean the wrench after use.
