PREPARING TOOL FOR USE
3.1.
Air Supply
3.1.1.
Ensure grinder air valve (or trigger) is in "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.
WARNING! Ensure the air supply is clean and does not exceed 90 psi while operating the grinder. 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 grinder.
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 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 die 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 fig 1 & 2.
