1. SAFETY INSTRUCTIONS
3Follow all workshop health & safety rules, regulations, and conditions when using tool.
pWARNING! Disconnect from air supply before changing cutting disc or servicing.
3Maintain tool in good condition and replace any damaged or worn parts. Use
genuine parts only. Non-authorised parts may be dangerous and will invalidate the warranty.
pWARNING! Check correct air pressure is maintained and not exceeded. We recommended 90psi.
3Keep air hose away from heat, oil and sharp edges. Check air hose for wear before each
use and ensure that all connections are secure.
pWARNING! Before each use check cutting disc is secure, and the disc is not worn or
damaged, if damaged replace immediately.
3Ensure replacement discs are not damaged in any way such as cracks, deformations or
splinters etc. Also check the mounting washer to ensure it is not deformed, burred or
notched. Damaged washer must not be used as it may cause irregular pressure on the disc
which may cause the disc to break. DO NOT over tighten a disc and never tamper with a disc
in order to adapt it to a different size holder.
3Always use the correct disc suitable for the material being cut. Ensure the maximum speed
specification of the cutting disc is higher than that indicated on the machine data plate.
pWARNING! Keep disc guard in place, tight and in good working order. The safety guard is a
mandatory fitting where tool is used in premises covered by the Health & Safety at Work Act.
pWARNING! Always wear approved eye and face protection when operating the tool.
3Use breathing protection in accordance with COSHH regulations if fumes or dust pose a hazard.
3Wear ear defenders and gloves if necessary.
3Keep hands and body clear of the workpiece when operating the tool.
3Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip shoes.
3Secure non stable work piece with a clamp, vice or other adequate holding device.
3Keep children and non essential persons away from the working area.
3Avoid subjecting disc to excessive strain, always ease disc down against workpiece (a harsh
impact may break the disc). Do not over press in order to cut workpiece. Maintain a controlled
adequate progression, which will emit a min imum of sparks.
8DO NOT get the tool wet or use in damp or wet locations.
8DO NOT hold the workpiece by hand. Use clamps or a vice to secure the workpiece.
7DO NOT use the tool for a task it is not designed to perform.
p p
WARNING! DO NOT use tool if damaged or faulty. Contact your local service agent.
7DO NOT use tool unless you have been instructed in its use by a qualified person.
7DO NOT position your body in line with the disc whilst cutting, and DO NOT remove
the safety guard whilst in use.
7DO NOT carry the tool by the air hose, or yank the hose from the air supply.
7DO NOT direct air from the air hose at yourself or others.
pWARNING! DO NOT cut any materials containing asbestos.

3.0 NOTE. This machine is capable of operating at speeds up to 22,000 rpm without a disc fitted
and around 21,000rpm with a disc fitted. We recommend that the air inlet pressure of this
machine be regulated to 90psi and be fitted with 1/4 bore hose and couplings. This will limit
the machines free speed to 20,000rpm
3.1. AIR SUPPLY( Recommended hook-up procedure is shown in fig 1.)
3.1.1. Ensure tool 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. pWARNING! Ensure the air supply is clean and does not exceed 90 psi while operating the
tool. 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 tool.
3.1.5. Clean air inlet filter weekly.
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 tool.
To overcome this, connect a leader hose to the tool. A quick change coupling may
then be used to connect the leader hose to the air line recoil hose. See fig 1 & 2.
pWARNING! Disconnect tool from air supply before changing accessories, servicing or
performing maintenance. Replace or repair damaged parts. Use genuine parts only. Non-
authorised parts may be dangerous and will invalidate the warranty.
5.1. 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 tool 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 tool 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 tool 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 tool and store in a safe, dry,
childproof location.
3. PREPARING TOOL FOR USE
5. MAINTENANCE
4.2. OPERATING
pWARNING! Ensure you have read, understood and apply safety instructions.
4.2.1. Connect the tool to the air supply.
4.2.2. To start the tool, hold firmly and push the trigger locking lever forward whilst depressing trigger.
4.2.3. The disc must be running at its maximum speed before attempting to cut the workpiece.
4.2.4. Slowly and smoothly bring the cutting disc toward the workpiece (avoid jerky movements).
4.2.5. Exert adequate pressure on the tool to allow cutting according to the type and size of the
material you are working with. Avoid subjecting disc to excessive strain, always hold tool
firmly and ease disc against workpiece (a harsh impact may break the disc). Maintain a
controlled adequate progression.
DO NOT allow tool to free run for an extended period of time as this will shorten its life.

4.1 FITTING CUTTING DISC
p p
WARNING! Disconnect from the air supply before changing disc.
4.1.1. Use hex key to remove hex screw (item 32 on the parts list) and washer (31).
4.1.2. Place the cutting disc onto the spindle.
4.1.3. Replace the washer and secure with hex screw, but do not over tighten.
Check that replacement disc is not damaged, (cracks, deformations or splinters etc).
Also check the mounting washer to ensure it is not deformed, burred or notched .
A damaged washer must not be used as it may cause irregular pressure on the
disc which may cause it to break. DO NOT tamper with a disc in order to adapt it to a
different size holder.
