3.1. Air Supply (Recommended hook-up is shown in fig.1).
3.1.1. Ensure grinder throttle 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 of 3.0cfm.
3.1.3.
WARNING! Ensure the air supply is clean and does not exceed 90psi. Too high an air
pressure or unclean air will shorten the life of the grinder 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 grinder.
3.1.5. Clean compressor air inlet filter weekly.
3.1.6. Line pressure should be increased to compensate for unusually long air hoses (over 8
metres). The minimum hose size should be 1/4” I.D. and fittings must have the same internal
bore.
3.1.7. Keep hose away from heat, oil and sharp edges. Check hose 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 grinder.
To overcome this, connect a leader hose to the grinder. 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 you read, understand and apply safety instructions before use.
4.1. To mount a grinding tip place the smaller spanner provided across the flats on the shaft (just
below the collet) to prevent the shaft from rotating. Loosen the collet using the larger spanner
and drop the shaft of the selected grinding tip into the collet. Tighten the collet until the shaft
of the grinding tip is secuely held.
