1.SAFETY INSTRUCTIONS
•Follow all workshop Health & Safety rules, regulations, and conditions when
using tool.
•WARNING! Disconnect from air supply before changing cutting disc or servicing.
•Maintain tool in good condition and replace any damaged or worn parts. Use
genuine parts only. Unauthorised parts may be dangerous and will invalidate the
warranty.
•WARNING! Check correct air pressure is maintained and not exceeded. We
recommend 90psi.
•Keep air hose away from heat, oil and sharp edges. Check air hose for wear
before each use and ensure that all connections are secure.
•WARNING! Before each use check cutting disc is secure and the disc is not
worn or damaged. If damaged replace immediately.
•Ensure 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.
•Always use a disc suitable for the material being cut. Ensure the maximum
speed specification of the cutting disc is the same as or higher than that
indicated on the machine data plate.
•WARNING! Keep disc guard in place, tight and in good working order. The
safety guard is a mandatory fitting where the tool is used in premises covered by
the Health & Safety at Work Act.
•WARNING! Always wear approved eye or face protection when operating the
tool.
•Use breathing protection in accordance with COSHH regulations if fumes or dust
pose a hazard.
•Wear ear defenders and gloves if necessary.
•Keep hands and body clear of the workpiece when operating the tool.
•Maintain correct balance and footing. Ensure the floor is not slippery and wear
non-slip shoes.
•Secure non stable workpiece with a clamp, vice or other adequate holding
device.
•Keep children and non essential persons away from the working area.
•Avoid 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
maximum of sparks.

•DO NOT hold the workpiece by hand. Use clamps or a vice to secure the
workpiece.
•DO NOT use the tool for a task it is not designed to perform.
•WARNING! DO NOT use tool if damaged or faulty. Contact your local service
agent.
•DO NOT use tool unless you have been instructed in its use by a qualified
person.
•DO NOT position your body in line with the disc whilst cutting, and DO NOT
remove the safety guard whilst in use.
•DO NOT carry the tool by the air hose, or yank the hose from the air supply.
•DO NOT direct air from the air hose at yourself or others.
•WARNING! DO NOT cut any materials containing asbestos.
•DO NOT switch the tool on whilst the disc is in contact with the workpiece.
•DO NOT allow workpiece to overheat. Periodically cool by immersing the
workpiece in water.
•DO NOT use tool where there are flammable liquids, solids or gases such as
paint solvents including waste wiping or cleaning rags etc as any sparks
generated may be dangerous.
•DO NOT touch the workpiece close to the ground surface as it will be very hot.
Allow to cool.The workpiece may also be very sharp.
•DO NOT operate tool if you are tired or under the influence of alcohol, drugs or
intoxicating medication. When not in use disconnect from air supply and store in
a safe, dry, childproof location.
2.INSTRUCTION & SPECIFICATION
The tools feature contoured, soft-grip handles and housings which help reduce
the effects of vibration and
chill – major contributors to circulatory and nerve problems such as white finger.
The tools also include exhaust systems designed to reduce noise levels by
baffling the noise or directing it away from the operator’s environment. Most of the
tools include integral and adjustable air valves for precise control of output. The
air wrenches are pound for pound, amongst the most powerful machines we have
seen in the market and the materials and manufacturing techniques used in the
production of all these series will ensure long and reliable service

3. PREPARATION
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 6.2bar, and an air flow according to
specification.
3.1.3. WARNING! Ensure the air supply is clean and does not exceed 90psi 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 compressor’s air tank daily. Water in the air line will damage the
tool.
3.1.5. Clean the compressor’s air inlet filter weekly.
3.1.6. L ine 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
4. OPERATION
4.1. CHANGING T HE CUTTING DISC
WARNING! Disconnect from the air supply before changing disc.

5
4.1.1. Use spanner to secure the shank and unscrew central hex screw with hex
key.
4.1.2. Remove the washer and old disc, place the new 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.
4.2. OPERATING
WARNING! 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 progression.
5. MAINTENANCE
WARNING! Disconnect tool from air supply before changing accessories,
servicing 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 the air supply does not include 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 tool after use.
5.3. Loss of power or erratic action may be due to the following:

6
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. When not in use, disconnect from air supply, clean tool and store in a safe,
dry, childproof location.
