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. pWARNING! 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.
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 hoses 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.
pWARNING! 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.
5.1. Lubricate the air wrench daily with a few drops of Sealey air tool oil dripped into the air inlet to
prolong its life.
5.2. Clean the wrench after use. DO NOT use worn, or damaged sockets.
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
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. If you continue to experience problems, contact your local
Sealey service agent.
5.4. 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,
childproof location.
3. PREPARING WRENCH FOR USE
4. OPERATING INSTRUCTIONS
5. MAINTENANCE
pWARNING! Ensure you read, understand and apply safety instructions before use.
4.1. Only use sockets specifically designed for use with a ratchet wrench.
4.2. Connect the wrench to the air hose as in chapter 3.
4.3. Place the socket over the subject nut and depress the trigger to operate the wrench.
4.4. To change ratchet direction turn the switch on the tool head. F = Forward R = Reverse.
DO NOT use any additional force upon the wrench in order to remove a nut.
4.5. The flow of air may be regulated by turning the screw above the trigger.
DO NOT allow wrench to run in idle rotation for an extended period of time as this will
shorten its life.
