2. INTRODUCTION
o
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 and powerful operation. Exhaust outlet adjusts 360°, keeping airflow 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.
Available with ‘Midi’ type body or for added power ‘Maxi’ bodied versions. Model No. SA656 features long reach shank with an overall length of
260mm.

4. PREPARATION
pr
4.1.
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.
4.1.1.
Ensure die grinder air valve (or trigger) is in “Off” before connecting to the air supply.
4.1.2. . You will require an air pressure of 90psi, and an air flow according to specification.
4.1.3.
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 8metres). The minimum hose diameter should be
1/4” internal diameter and fittings must have compatible 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.
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.
5. OPERATION
5.1.
Fitting Grinding Bit
WARNING!
Disconnect from the air supply before changing grinding stone.
5.1.1.
Check that grinding stones are not damaged in any way such as cracks, deformations or splinters etc. Damaged stones must not be
used.
5.1.2.
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.
5.2.
Operating
WARNING!
Ensure you have read, understood and apply Section 1 safety instructions.
5.2.1.
Connect the die grinder to the air supply as described in Section 4..
5.2.2.
To start, hold firmly and push the trigger locking lever forward whilst depressing trigger.
5.2.3.
The stone must be running at its maximum speed before attempting to grind the workpiece.
5.2.4.
Slowly and smoothly bring the grinding stone toward the workpiece (avoid jerky movements). Exert adequate pressure on the die grinder
to grind according to the type and size of the material you are working with. Avoid subjecting bit to excessive strain or harsh impacts.
Always hold die grinder firmly and ease grinding stone against workpiece. Maintain a controlled progression.
8
DO NOT
allow die grinder to free run for an extended period of time as this will shorten its life.
