Sealey SA21/S - Manual (Page 2)

3.1. Air Supply
3.1.1. Ensure the 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. p WARNING! Ensure that 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 the 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 the 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.
3. PREPARING WRENCH FOR USE
4. OPERATING INSTRUCTIONS
p WARNING! 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 section 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.
4.6. DO NOT allow wrench to run in “idle rotation” for an extended period of time as this will
shorten its life.
