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 the 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 & fig.2.

5. OPERATION
WARNING! Ensure you read, understand and apply safety instructions before use.
‰
5.1.
With seized or rusted nut, use penetrating oil and a spanner to "crack" the fixing before using the wrench.
5.2.
Fit the required socket to the wrench.
5.3.
Connect the wrench to the air hose as indicated in section 4.
5.4.
CHANGE FROM 1/2" DRIVE TO 1/4" DRIVE
5.4.1.
Partially remove grub screw from side of 1/2" drive and remove to reveal 1/4" drive. Store securely.
5.5.
Place the socket over the subject nut and depress the trigger to operate the wrench.
5.6.
To change the wrench direction turn the switch on the head of the wrench (see fig.3). F = Clockwise, R = Anti-clockwise.
DO NOT use worn or damaged sockets.
8
DO NOT use any additional force upon the wrench in order to remove a nut; it is possible to damage the head by using excessive
8
hand force.
DO NOT allow the wrench to free run for an extended period of time as this will reduce 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. Un-authorised parts may be dangerous and will invalidate the warranty.
6.1.
If the air system does not have an oiler, 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 with a dry cloth.
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
paraffin. Allow to drain before use.
6.4.
For a full service contact your local Sealey service agent.
6.5.
When not in use, disconnect from the air supply, clean the wrench with a dry cloth and store in a safe, dry, childproof location.
