2. INTRODUCTION & SPECIFICATION
Recommended hook-up is shown in fig. 1.
3.1. Ensure that the polisher air valve (or throttle) is in the "off" position before connecting to the air supply.
3.2. You will require an air pressure between 70-90psi, and an air flow according to the specification above.
3.3. WARNING! Ensure that the air supply is clean and does not exceed 90psi while operating the polisher.
Too high an air pressure and/or unclean air will result in excessive wear and may be dangerous, causing
damage and/or personal injury.
3.4. Drain the compressor air tank daily. Water in the air line will damage the polisher and invalidate your
warranty.
3.5. Clean compressor air inlet filter weekly.
3.6. 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.
3.7. Keep hoses away from heat, oil and sharp edges. Check hoses for wear, and make certain that all
connections are secure.
3.8. Vibration may cause failure if a quick change coupling is connected directly to the 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.

4. OPERATING INSTRUCTIONS
WARNING! Ensure that you read, understand and apply the safety instructions before use.
4.1. Ensure the hook and loop pad is securely fitted to the spindle. Using the spanner provided to hold the
spindle, turn the pad clockwise until tight.
4.2. Attach the compounding pad by firmly placing on the hook and loop pad.
4.3. Press trigger to start the polisher, release trigger to stop.
Always use a polishing pad appropriate for the job. Work progressively from coarse to finer grades. DO NOT go
from coarse to fine in one step as it may be difficult to remove swirl marks left by the coarse pad.
DO NOT apply excessive pressure, let the polisher do the work for you. Start the polisher and bring the pad to
the work surface evenly and slowly. Move the polisher back and forth in overlapping areas. Remove the pad
from the work surface before stopping the polisher. Regularly check the pad for wear, always change a damaged
pad.
DO NOT allow the polisher to run in idle rotation for an extended period of time as this will reduce bearing life.
