PREPARATION
4.1. AIR SUPPLY
4.1.1. Recommended hook-up procedure is shown in fig.1.
4.1.2. Ensure die grinder air 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 die grinder. Too high an air pressure and contaminated air will
shorten the product life owing to excessive wear, and may be dangerous causing
damage and/or personal injury.
Drain the air tank daily. Water in the air line will damage the die grinder.
4.1.4. Clean air inlet filter weekly.
4.1.5. 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.
4.1.6. 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 die grinder.
4.2.2. 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. 
OPERATION
