use and ensure that all connections are secure.
Wear approved safety eye/face shield, ear defenders and hand protection.
Remove ill-fitting clothing. Remove ties, watches, rings and other loose jewellery and

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.

5. MAINTENANCE
WARNING!Disconnect wrench from air supply before changing accessories, servicing or
performing maintenance.Replace or repair damaged parts. Use genuine parts only.
Unauthorised parts may be dangerous and will invalidate the warranty.
5.1. If the air supply system does not have an oiler, lubricate the wrench daily with a few drops
of air tool oil, dripped into the air inlet before use (Sealey part no’s. ATO500S (500ml)
or ATO1000S (1 Litre)).
5.2. Clean the wrench after use.
5.3. Loss of power or erratic action may be due to the following:
a) Excessive drain on the air line. Moisture or restriction in the air pipe. Incorrect size or
type of hose connectors. To remedy, check the air supply and follow instructions in
Section 3.
b) Grit or gum deposits in the wrench may also reduce performance. Remove the strainer,
clean it and flush the wrench out with gum solvent oil or an equal mixture of SAE No
10 oil and paraffin. Allow to dry before use.
5.4. If you continue to experience problems, or for a full service, contact your local Sealey
service agent.
5.5. When not in use, disconnect from air supply, clean wrench and store in a safe, dry,
