3.1. Air Supply

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.
3.1.1. Ensure die grinder air valve (or trigger) is in "Off" 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. Drain the air tank daily. Water in the air line will damage the die grinder.
3.1.4. Clean air inlet filter weekly.
3.1.5. Line pressure should be increased to compensate for unusually long air hoses (over
8metres). The minimum hose diameter should be 1/4” internal diameter and fittings must
have compatible dimensions.
3.1.6. 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 (Sealey ref: AH2R or
AH2R/38). A quick change coupling may then be used to connect the leader hose to the air
line recoil hose. See fig 1 & fig 2.

Composite cover moulded around lightweight aluminium alloy housing reduces effects of chill on
operator’s hands and provides added control. Air motor with quality bearings for smooth powerful
operation. Exhaust outlet adjusts 360° keeping air flow away from operator. Safety trigger prevents
inadvertent operation. Ideal for re-shaping, deburring and smoothing off rough edges on castings.
Suitable for the professional workshop.
4.1. Fitting Grinding Bit

WARNING! Disconnect from the air supply before changing grinding stonw.
4.1.1. Check that grinding stones are not damaged in any way such as cracks, deformations or
splinters etc. Damaged stones must not be used.
4.1.2. Use the spanners supplied to loosen collet locking collar. Insert grinding stone ensuring that
a minimum of 10mm gripping length is observed and re-lock collar.
