Sealey SA722 - Manual (Page 2)

3.1. Air Supply
3.1.1. Ensure the polisher 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 the specifications.
3.1.3. p WARNING! Ensure the air supply is clean and does not exceed 90psi while operating the polisher.
Too high an air pressure and/or 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 polisher and will invalidate your warranty.
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
3.2.1 Vibration may cause failure if a quick change coupling is connected directly to the air polisher. To
overcome this, connect a leader hose to the polisher. A quick change coupling may then be used to
connect the leader hose to the air line recoil hose. See figs.1 & 2.

WARNING! Ensure you read, understand and apply the safety instructions in Section 1 before use.
4.1. Assembly
4.1.1. Screw the backing pad into the polisher spindle, then
tighten with supplied spanner. Attach the compounding
pad, only use pads with speed ratings equal to or
higher than the speed rating of the polisher.
DO NOT use cloth backed polishing pads.
4.1.2. Connect air supply to polisher and press the trigger
(fig.3C) to check that the polisher is working correctly.
4.2. Operating
4.2.1 The polisher speed can be changed by switching the
thumb control on the side of the polisher (fig.3A).
4.2.2 Operate the polisher by depressing the trigger (fig.3C).
4.2.3. Always use a polishing compound appropriate for the
job.
4.2.4. DO NOT apply excessive pressure, let the polisher do the work for you. Start the polisher and bring the
polishing pad to the work surface evenly and slowly. Move the polisher back and forth in overlapping
areas.
4.2.5. Remove the polishing pad from the work surface before stopping the polisher. Regularly check the
polishing pad for wear, always change if worn or damaged.
4.2.6. DO NOT allow polisher to run in “idle rotation” for an extended period of time as this will reduce bearing
life.
