Sealey SA650.V3 User manual

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 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.
WARNING! 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.
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 unstable 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 use force in order to cut workpiece. Maintain a controlled progression.
DO NOT get the tool wet or use in damp or wet locations.
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 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. Cool using an oil lubricant.
 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.

INSTRUCTIONS FOR:
AIR CUT-OFF TOOL 75MM
MODEL No: SA650.V3

3.1. Air Supply
Recommended hook-up procedure is shown in fig 1.
3.1.1. Ensure tool air control 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. 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 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.

disc which may cause it to break. DO NOT tamper with a disc in order to adapt it to a
different size holder.

 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 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 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.

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.

Risk of Hand Arm Vibration Injury.
Air Cut-Off Tool 75mm, Model No. SA650.V3 ,when operated in accordance with these instructions and tested
in accordance with BS EN 28662-1:1993, ISO 8662-1:1988 and BS EN ISO 28927-8:2009 r esults in the
following vibration emission declared in accordance with BS EN12096:1996.
Measured vibration emission value: 1.9 m/s ² Uncertainty: 0.76 m/s ²
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.
This is a ‘NO LOAD’ vibration figure.
A competent person should carry out a risk assessment following HSE guidelines.
Measurement results can be highly variable, depending on many factors, including the operator's technique,
the condition of the work equipment, the material being processed and the measurement method.
Recommended Measures to reduce risk of hand-arm vibration syndrome:
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.
Danger of Fire/Explosion Hazard
WARNING! The grinding process can produce streams of sparks (especially when grinding metal), which
are a potential source of ignition.
DO NOT use the grinder where there are flammable liquids, solids or gases.
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.
