DANGER OF FIRE/EXPLOSION HAZARD
WARNING! The grinding process can produce streams of sparks which are a potential source of ignition, especially when grinding
o
o
metal.
DO NOT use the grinder where there are flammable liquids, solids or gases.
7
7
DO NOT allow grinder sparks to make contact with the operator’s clothing or any other fabric such as cleaning rags. Fabrics

contaminated with inflammable materials such as petrol, oil, grease, paint and solvents are a particular fire hazard.
To reduce the risk of clothing catching fire the operator should wear wool or cotton outer garments treated with a fire retardant in

preference to man-made fibres.
Risk of Hand Arm Vibration Injury
Micro Air Die Grinder Model SA673
when operated in accordance with these instructions and tested in
accordance with EN 28662-2: 1994 results in the following vibration emission declared in accordance with
BS EN12096: 1996.
Measured vibration emission value: . . . . . . . . . . .0.2m/s²
Uncertainty: . . . . . . . . . . . . . . . . . . . . . . . . . . . . .0.1m/s²
These values are suitable for comparison with emission levels of other tools that have been subject to
the same test.
This tool may cause hand-arm vibration syndrome if its use is inadequately managed.
Recommended Measures to reduce risk of hand-arm vibration syndrome:
This item represents a low Hand Arm Vibration risk to users. The calculated maximum usage period exceeds 8
hours. We recommend appropriate safety equipment is utilised and regular breaks for the operator are
employed to reduce any residual risk of fatigue or repetitive strain injury.

PREPARING TOOL FOR USE
3.1
AIR SUPPLY
Recommended hook-up procedure is shown in fig 1.
p
WARNING! Ensure the air supply is clean and does not exceed 90psi while operating the
p
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 switch is in the "off" position before connecting to the air
supply.
3.1.2 You will require an air pressure of 90psi.
3.1.3 Drain the compressors air tank daily. Water in the air line will damage the die grinder.
3.1.4 Clean the compressors air inlet filter weekly.
3.1.5 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.
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. A quick change coupling
may then be used to connect the leader hose to the air line recoil hose. See figs 1 & 2.

OPERATING INSTRUCTIONS
4.1
OPERATING
p
WARNING! Ensure you read, understand and apply safety instructions.
p
4.1.1 Connect the die grinder to the air supply.
4.1.2 To start, hold firmly and twist the gripped section (“ON” and “OFF” are marked on the body).
4.1.3 The bit must be running at its maximum speed before attempting to grind the workpiece.
4.1.4 Slowly and smoothly bring the grinding stone toward the workpiece (avoid jerky
movements).
Avoid subjecting stone to excessive strain or harsh impacts.
Always hold die grinder firmly and ease grinding stone against workpiece. Maintain a
controlled progression.
4.2
CHANGING GRINDING STONES
p
WARNING! Disconnect from the air supply before changing grinding stone.
p
4.2.1 Check that grinding stones are not damaged in any way such as cracks, deformations
or splinters etc. Damaged stones must not be used.
4.2.2 Use wrenches provided to loosen collet locking collar. Insert grinding bit and re-lock collar.
DO NOT allow die grinder to free run for an extended period of time as this will shorten
7
bearing life.
5.
MAINTENANCE
p
WARNING! Disconnect die grinder from air supply before changing accessories, servicing
p
or performing maintenance. Replace or repair damaged parts. Use genuine parts only.
Unauthorised parts may be dangerous and will invalidate the warranty.
5.1
If air supply does not have an oiler, lubricate the air tool daily with a few drops of Sealey air
tool 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.
