INSTRUCTIONS FOR
AIR CUT-OFF TOOL Ø75MM
MODEL NO: GSA25.V2
Thank you for purchasing a Sealey product. Manufactured to a high standard, this product will, if used according to these instructions,
and properly maintained, give you years of trouble free performance.
IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS, WARNINGS & CAUTIONS. USE
THE PRODUCT CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGE AND/OR
PERSONAL INJURY AND WILL INVALIDATE THE WARRANTY. KEEP THESE INSTRUCTIONS SAFE FOR FUTURE USE.
1. SAFETY
9Follow all workshop Health & Safety rules, regulations, and conditions when using tool.
WARNING! Disconnect from air supply before changing cutting disc or servicing.
9Maintain 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.
9Keep 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.
9Ensure 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. A 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.
9 Alwaysuseadiscsuitableforthematerialbeingcut.Ensurethemaximumspeedspecicationofthecuttingdiscisthesameasor
higher than that indicated on the machine data plate.

9Secure unstable workpiece with a clamp, vice or other adequate holding device.
9Keep children and non essential persons away from the working area.
9Avoid 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.
8DO NOT hold the workpiece by hand. Use clamps or a vice to secure the workpiece.
8DO NOT use the tool for a task it is not designed to perform.

4. PREPARATION
4.1. AIR SUPPLY
Recommended hook-up procedure is shown in fig 1.
4.1.1. Ensure tool air valve (or trigger) is in “off” position before connecting to the air supply.
4.1.2. You will require an air pressure of 90psi, and an air flow according to specification.
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.
9Drain the compressor’s air tank daily. Water in the air line will damage the tool.
9Clean the compressor’s air inlet filter weekly.
9Line 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.
9Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.
4.2. COUPLINGS
4.2.1. Vibration may cause failure if a quick change coupling is connected directly to the tool.
4.2.2. 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g1.
5. OPERATION
5.1. CHANGING THE CUTTING DISC
WARNING! Disconnect from the air supply before changing disc.
5.1.1. Use spanner to secure the shank and unscrew central hex screw with hex key.
5.1.2. Remove the washer and old disc, place the new cutting disc onto the spindle.
5.1.3. Replace the washer and secure with hex screw, but do not over tighten.
5.1.4.
Check that replacement disc is not damaged (cracks, deformations or splinters etc).
5.1.5. Also check the mounting washer to ensure it is not deformed, burred or notched.
5.1.6. 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
5.2. OPERATION
WARNING! Ensure you have read, understood and apply safety instructions.
5.2.1. Connect the tool to the air supply.
5.2.2. To start the tool, hold firmly and push the trigger locking lever forward whilst depressing trigger.
5.2.3. The disc must be running at its maximum speed before attempting to cut the workpiece.
5.2.4. Slowly and smoothly bring the cutting disc toward the workpiece (avoid jerky movements).
5.2.5.
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.
5.3. SAFETY
  TheAirCut-OffToolhasimprovedfeaturesincluding:
360° rotating exhaust, this allows the user to direct airflow away from the body/hands. This is located at the base of the tool’s handle
  Variableair-valve,allows4differentdegreesofairvolumeintotheunit.
8DO NOT allow tool to free run for an extended period of time as this will shorten its life.
6. 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.

6.1. 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.
6.2. Clean the tool after use.
6.3. 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 4.
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.
6.4. For a full service contact your local Sealey service agent.
6.5. When not in use, disconnect from air supply, clean tool and store in a safe, dry, childproof location.
WARNING! – Risk of Hand Arm Vibration Injury.
This tool may cause Hand Arm Vibration Syndrome if its use is not managed adequately.
This tool is subject to the vibration testing section of the Machinery Directive 2006/42/EC.
This tool is to be operated in accordance with these instructions.
Measured vibration emission value (a): ...........0.8 m/s²
Uncertainty value (k):...........................0.4 m/s²
Please note that the application of the tool to a sole specialist task may produce a different average vibration emission. We recommend that a
specific evaluation of the vibration emission is conducted prior to commencing with a specialist task.
A health and safety assessment by the user (or employer) will need to be carried out to determine the suitable duration of use for each tool.
NB: StatedVibrationEmissionvaluesaretype-testvaluesandareintendedtobetypical.
Whilst in use, the actual value will vary considerably from and depend on many factors.
Such factors include; the operator, the task and the inserted tool or consumable.
NB: ensure that the length of leader hoses is sufficient to allow unrestricted use, as this also helps to reduce vibration.
The state of maintenance of the tool itself is also an important factor, a poorly maintained tool will also increase the risk of Hand Arm Vibration
Syndrome.
Health surveillance.
We recommend a programme of health surveillance to detect early symptoms of vibration injury so that management procedures can be modified
accordingly.
Personal protective equipment.
We are not aware of any personal protective equipment (PPE) that provides protection against vibration injury that may result from the
uncontrolled use of this tool. We recommend a sufficient supply of clothing (including gloves) to enable the operator to remain warm and dry and
maintain good blood circulation in fingers etc. Please note that the most effective protection is prevention, please refer to the Correct Use and
Maintenance section in these instructions. Guidance relating to the management of hand arm vibration can be found on the HSC website
www.hse.gov.uk-Hand-ArmVibrationatWork.
