4. PREPARATION
4.1. Air Supply
4.1.1. Ensure wrench air valve (or trigger) is in the “o” position before connecting to the air supply.
4.1.2. You will require an air pressure of 90psi, and an air flow according to specification.
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.
4.1.3. Drain the air tank daily. Water in the air line will damage the wrench.
4.1.4. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig.1.
4.1.5. 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.

4.1.6. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.
4.2. 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.
fig.1
4.3. Handle Assembly
Attach the side handle to the wrench with bolts provided.
fig.2
5. OPERATION
WARNING! Ensure you read, understand and apply safety instructions before use.
5.1. Only use impact sockets which are specically designed for use with an impact wrench.
5.2. Connect the wrench to the air hose as in section 4 .
5.3. To undo a nut turn the direction/airow lever on the back face of the unit to the left so that it points to the ‘L’ symbol.
5.4. Place the socket over the subject nut and depress the trigger to operate the wrench.
8 DO NOT use any additional force upon the wrench in order to remove a nut.
5.5. To tighten a nut move the direction/airow lever on the back face of the unit to the right so that it points to the ‘1’ for low power. To
increase the power turn the lever further to the right selecting ‘2’ or ‘3’. When the lever is all the way to the right adjacent to the ‘R’
symbol the unit is at full power.
8 DO NOT allow wrench to free run for an extended period of time, this will shorten its life.
6. MAINTENANCE
WARNING! Disconnect wrench from air supply before changing accessories, servicing or performing maintenance. Replace or repair
damaged parts. Use genuine parts only. Non-authorised parts may be dangerous and will invalidate the warranty.
6.1. Lubricate the air wrench daily with a few drops of Sealey air tool oil dripped into the air inlet to prolong its life.
6.2. Clean the wrench after use. DO NOT use worn, or damaged sockets.
6.3. 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 4.
b) Grit or gum deposits in the wrench may also reduce performance. If your model has an air strainer (located in the area of the air
inlet), remove the strainer and clean it. Flush the wrench out with gum solvent oil or an equal mixture of SAE No 10 oil and paran.
Allow to dry before use.
6.4. For a full service contact your local Sealey service agent.
6.5. When not in use, disconnect from air supply, clean wrench and store in a safe, dry, childproof location.
