1. SAFETY
Refer to
Instructions
Follow all workshop Health & Safety rules, regulations and conditions when using tool.
WARNING! Disconnect from air supply before changing bit or servicing.
Maintain grinder 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 recommended 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 grinding bit is secure, and the bit is not worn or damaged, if damaged, replace
immediately.
Ensure replacement grinding bits are not damaged (cracks, deformations or splinters etc).
Always use the correct grinding bit suitable for the material being ground. Ensure the maximum speed specification of the bit is
higher than that indicated on the machine data plate.
WARNING! Always wear approved eye or face protection when operating the grinder.
Use breathing protection in accordance with COSHH regulations if fumes or dust pose a hazard. Wear ear defenders and
safety gloves.
Keep hands and body clear of the workpiece when operating the grinder.
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 grinding bit to excessive strain, always ease grinding bit against workpiece (a harsh impact may break the bit).
Maintain a controlled, adequate progression.
DO NOT get the grinder 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 grinder for a task it is not designed to perform.
WARNING! DO NOT use grinder if damaged or faulty. Contact your local service agent.
DO NOT use grinder unless you have been instructed in its use by a qualified person.
DO NOT carry the grinder 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 grind any materials containing asbestos.
DO NOT turn the grinder on whilst the grinding bit is in contact with the workpiece.
DO NOT use grinder where there are flammable liquids, solids or gases such as paint solvents, including waste wiping or
cleaning rags etc as generated sparks 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 grinder if you are tired, 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.
LEAD PAINT WARNING!
Paint once contained lead as a traditional ingredient. Dust from the removal of such paint is toxic and contact with it must be
avoided. The following action must be taken when using the sander on paint that you suspect may contain lead.
1. User must determine potential hazard relating to age of paint to be removed (modern paints do not contain lead).
2. DANGER! Keep all persons and pets away from the work area. The following are particularly vulnerable to the effects of lead paint dust:
Pregnant women, babies and children.
3. We recommend personal protection by using the following safety items:
a) Paint Spray Respirator
b) PE Coated Hooded Coverall
c) Latex Gloves
4. Take adequate measures to contain the paint dust, flakes and scrapings.
5. Continue to wear safety equipment as in (3) above and clean all areas thoroughly when the task is complete.

4. PREPARATION
4.1. Air Supply
4.1.1. Ensure grinder air valve (or trigger) is in "off" position before connecting to the air supply.
4.1.2. Use an air pressure of 90psi, and an air flow according to specification.
4.1.3. WARNING! Ensure the air supply is clean and does not exceed 90 psi while operating the 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 ury.
4.1.4. Drain the air tank daily. Water in the air line will damage the grinder.
4.1.5. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig 1.
4.1.6. 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.
4.1.7. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.
4.2. 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 fig 1 & 2.

Maintain a controlled, adequate progression.
DO NOT allow grinder to free run for an extended period as this will shorten its life.
6. MAINTENANCE
WARNING!Disconnect grinder 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 system does not include an oiler lubricate the air grinder daily with a few drops of Sealey air grinder oil dripped into the air
inlet to prolong its life.
6.2. Clean the grinder 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 3.
b) Grit or gum deposits in the 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 grinder out with gum solvent oil or an equal mixture of SAE No 10 oil and paraffin. Allow to dry
before use.

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):
Uncertainty value (k):...........................0.7 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 HSE website
www.hse.gov.uk - Hand-Arm Vibration at Work.
