Danger of Fire/Explosion Hazard
WARNING! The grinding process can produce streams of sparks (especially when grinding metal), which are a potential source of
ignition.
8DO NOT use the grinder where there are flammable liquids, solids or gases.
8DO NOT allow grinder sparks to make contact with the operator’s clothing or any other fabric such as cleaning rags. Fabrics
contaminated with inflammable materials such as petrol, oil, grease, paint and solvents are a particular fire hazard.
9To reduce the risk of clothing catching fire the operator should wear wool or cotton outer garments treated with a fire retardant in
preference to man-made fibres.

4.1. AIR SUPPLY
4.1.1. Recommended hook-up procedure is shown in fig 1.
4.1.2. Ensure tool air control valve (or trigger) is in “Off” position before connecting to the air supply.
4.1.3. You will require an air pressure of 90psi, and an air flow according to specification.
WARNING! Ensure the air supply is clean and does not exceed 90psi while operating the tool. 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.
4.1.4. Drain the air tank daily. Water in the air line will damage the tool.
4.1.5. Clean air inlet filter weekly.
4.1.6. 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.
4.1.7. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.
4.2. COUPLINGS
4.2.1. Vibration may cause failure if a quick change coupling is connected directly to the tool. To overcome this, connect a leader hose to
the tool. A quick change coupling may then be used to connect the leader hose to the air line recoil hose (see gs.1 & 2).
5. OPERATION
