PREPARING TOOL FOR USE
3.1.
Air Supply
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. p WARNING! Ensure the air supply is clean and does not exceed 90 psi 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. 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.

4. OPERATING INSTRUCTIONS
4.1
FITTING grinding bit
WARNING! Disconnect from the air supply before changing grinding bit.
4.1.1. Check that grinding bits are not damaged in any way such as cracks, deformations
p
or splinters etc. Damaged bits must not be used.
4.1.2. Use wrenches enclosed to loosen collet locking collar. Insert grinding bit and re-lock collar.
4.2.
OPERATING
WARNING! Ensure you have read, understood and apply safety instructions.
4.2.1.
Connect the die grinder to the air supply.
p
4.2.2.
To start, hold firmly and push the trigger locking lever forward whilst depressing trigger.
4.2.3.
The bit must be running at its maximum speed before attempting to grind the workpiece.
4.2.4. Slowly and smoothly bring the grinding bit 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 bit against workpiece. Maintain a
controlled adequate progression.
DO NOT allow die grinder to free run for an extended period of time as this will shorten its life.
5. MAINTENANCE
WARNING! Disconnect die grinder from air supply before changing accessories, servicing or
performing maintenance. Replace or repair damaged parts. Use genuine parts only. Non-
p
authorised parts may be dangerous and will invalidate the warranty.
5.1.
Lubricate the air die grinder daily with a few drops of Sealey air die grinder oil dripped into
the air inlet to prolong its life.
5.2.
Clean the die grinder after use.
5.3.
Loss of power or erratic action may be due to the following:
a) Excessive drain on the air line. Moisture or restriction in the air pipe. Incorrect size or
type of hose connectors. To remedy check the air supply and follow instructions in
chapter 3.
b) Grit or gum deposits in the die grinder may also reduce performance. If your model has
an air strainer (located in the area of the air inlet), remove the strainer and clean it. Flush
the die grinder out with gum solvent oil or an equal mixture of SAE No 10 oil and
paraffin. Allow to dry before use.
5.4.
For a full service contact your local Sealey service agent.
5.5.
When not in use, disconnect from air supply, clean die grinder and store in a safe, dry,
childproof location.
5.6.
Periodically lubricate crown and pinion gear with general purpose grease through the grease
nipple on head.
