3. PREPARING TOOL FOR USE
3.1. Air Supply
Recommended hook-up procedure is shown in fig.1.
3.1.1. Ensure die 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 90psi while operating the die 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 die grinder.
3.1.5. Clean 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 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.
