4. PREPARATION
4.1.
AIR SUPPLY Recommended hook-up procedure is shown in (fig.1).
4.1.1
Ensure wrench air valve (or trigger) is in the "off" position (i.e. released) 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 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.
4.1.3. Drain the compressor air tank daily. Water in the air line will damage the wrench.
4.1.4. Clean air inlet filter weekly. 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.
4.1.5 . 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 (fig.1 & 2).

5. OPERATION
WARNING! Ensure you read, understand and apply safety instructions before use.
‰
5.1.
Only use impact sockets which are specifically designed for use with an impact wrench.
DO NOT use worn or damaged sockets.
8
5.2.
Connect the wrench to the air hose as in section 4.
5.3.
Place the socket over the subject nut and depress the trigger to operate the wrench.
5.4.
To change direction, twist the switch on the rear of the wrench (fig.3), "anti-clockwise"
for reverse and "clockwise" for forward.
5.5.
The flow of air may be regulated by the switch on the back of the wrench, there are
three settings in the forward position.
DO NOT use any additional force upon the wrench in order to loosen/tighten a fixing.
8
DO NOT allow wrench to free run for an extended period of time as this will shorten
8
bearing 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. Unauthorised parts may be dangerous and will invalidate the warranty.
6.1.
If the air system does not have an oiler then lubricate the air wrench daily with a few drops of Sealey air tool oil dripped into the air inlet.
6.2.
Check and top up the gearbox by removing grub screw located on the side of the body adjacent to the trigger.
6.3.
Clean the wrench after use.
6.4.
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 chapter 3.
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 paraffin.
Allow to dry before use.
6.5.
For a full service contact your local Sealey service agent.
6.6.
When not in use, disconnect from air supply, clean wrench and store in a safe, dry, childproof location.
