Before Each Use

Thank you for selecting this CLARKE 230mm (9”) Angle Grinder, designed for use in a light industrial environment. Before attempting to use the tool, please read this leaflet thoroughly and follow the instructions carefully. In doing so you will ensure the safety of yourself and that of others around you, and you can look forward to the Angle Grinder giving you long and satisfactory service.

1. Always inspect the tool before use, and ensure it is in top condition.

2. Ensure air vents are clear, use compressed air at low pressure, to clean the tool where possible. (Always wear protective goggles when using compressed air).

3. Check the power cable to ensure it is sound and free from cracks, bare wires etc.

4. Ensure the grinding wheel or cutting disc is perfectly sound, free from cracks or damage in any way. Replace the disc when it is worn to 150mm diameter, or if it is chipped or cracked. Never use the grinder with a damaged disc. Only fit replacement discs with an outside diameter of 230mm (9”), and a bore of 22mm. If in doubt, consult your dealer.

After every 50 hours of use.

Unscrew Carbon Brush Caps, withdraw the Carbon Brushes and check their condition. They must be replaced when they have worn down to 6mm in length. If they are found to be serviceable, blow the brush holder clean with low pressure compressed air, and replace. Take care to avoid damaging the spring or wire when changing brushes.

The gearbox and motor are lubricated during manufacture, and further lubrication is not normally needed.

GENERAL SAFETY PRECAUTIONS

WARNING:

As with all machinery, there are certain hazards involved with their operation

and use. Exercising respect and caution will considerably lessen the risk of

personal injury. However, if normal safety precautions are overlooked or

ignored, personal injury to the operator or damage to property, may result.

1. READ and BECOME FAMILIAR with the entire operating manual. Learn the tools’ applications, limitations and the specific potential hazards peculiar to it.

2. ALWAYS ensure that ADEQUATE LIGHTING is available. A minimum intensity of 300 lux should be provided. Ensure that lighting is placed so that you will not be working in your own shadow.

3. CHECK for DAMAGE. Before using the tool, any damaged part should be checked to ensure that it will operate properly and perform its intended function. Check for alignment of moving parts, breakage of parts, mountings and any other condition that may affect the tools’ operation. Any damage should be properly repaired or the part replaced. If in doubt, DO NOT USE the tool. Consult your local dealer.

4. DISCONNECT the TOOL from the power supply before servicing and when changing accessories.

5. ALWAYS WEAR SAFETY GOGGLES manufactured to the latest European Safety Standards. Everyday eyeglasses do not have impact resistant lenses, they are NOT safety glasses.

6. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.

Page 4

7. NEVER force the tool. It will do a better and safer job at the rate for which it was designed.

8. ALWAYS USE A FACE OR DUST MASK if operation is particularly dusty.

9. DRUGS, ALCOHOL, MEDICATION. Do not operate tool while under the influence of drugs, alcohol or any medication.

10. USE RECOMMENDED ACCESSORIES. The use of improper accessories could be hazardous.

11. NEVER LEAVE THE TOOL RUNNING UNATTENDED. Turn power OFF. Do not leave the tool until it comes to a complete stop.

12. AVOID DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet locations or expose them to rain. Keep your work area well illuminated. DO NOT USE in explosive atmosphere (around paint, flammable liquids etc.).

13. KEEP CHILDREN AWAY. All visitors should be kept a safe distance from the work area, especially whilst operating the tool.

14. MAINTAIN TOOL IN TOP CONDITION. Keep tools clean for the best and safest performance. Follow maintenance instructions.

15. DON’T OVERREACH. Keep your proper footing/balance at all times. For best footing wear rubber soled footwear. Keep floor clear of oil, scrap wood, etc.

16. WEAR PROPER APPAREL. Loose clothing or jewellery may get caught in moving parts. Wear protective hair covering to contain long hair.

17. HANDLE WITH EXTREME CARE Do Not carry the tool by its’ electric cable, or yank the cable to disconnect it from the power supply .

18. AVOID ACCIDENTAL STARTING. Ensure the switch is OFF before plugging in to mains.

19. BE AWARE that accidents are caused by carelessness due to familiarity. ALWAYS concentrate on the job in hand, no matter how trivial it may seem.

20. ALWAYS store the tool in a clean dry environment when not in use, out of reach of children

21. ALWAYS guard against electric shock, avoid contact with earthed surfaces - pipes, radiators etc.

22. ALWAYS secure work - use a vise or clampswhenever possible.

ADDITIONAL PRECAUTIONS FOR ANGLE GRINDERS

1. It is strongly advised that you wear ear protectors/defenders as the noise level during operation, depending upon the work being carried out, can exceed safe working levels.

2. Always wear a good pair of industrial gloves to avoid potential injury from sparks and debris.

3. Do not use the tool if the electric cable, plug or motor is in poor condition.

3.Hand Grip (3-position)

A threaded hole, on the top, left and right hand side of the gear housing, is provided so that the hand grip may be screwed in, as required, to provide left or right hand control of the tool.

OPERATION Re: Fig.3

IMPORTANT! For safety, ensure the wheel is perfectly secure and the guard is set to the desired position to give maximum protection, and is also secure.

Fig 3.

The hand holding the body will control trigger switch, whilst the other hand grasps the hand grip and guides the tool over the workpiece.

Holding the tool firmly but not tightly, press the Trigger Safety button and pull up the trigger. The tool incorporates a ‘soft’ delayed start, therefore allow a second or two for the tool to reach full speed.

IMPORTANT! When renewing or replacing a disk/grinding wheel, ALWAYS allow the tool to free run for at least one minute, to check the disk/wheel is mounted correctly, any vibration should be investigated and rectified immediately. The tool should not be used should vibrations exist.

Allow the tool to do the work...DO NOT force the disk on to the workpiece and avoid putting any sideways pressure on cutting discs.

For rough grinding, hold the tool at an angle of 20-40 degrees to the work surface as shown in Fig.2.

To stop the tool, simply release the trigger. There is NO trigger hold device as this is undesirable for this type of tool. NEVER stop the grinder whilst it is in contact with the work. ALWAYS wait until it has come to a compete stop before placing it down carefully to avoid damaging the cutting/grinding disk.

If the machine is overloaded, or used for a long period, it will become hot. Running the machine on no-load for a few minutes will allow the internal fan to cool the motor to its normal temperature.

When using a cutting disk, avoid tilting the disk as it must present a clean cutting edge to the work. NEVER use a cutting disk to cut asbestos, or for rough grinding,

or for side grinding.

ASSEMBLY

1. Mounting the Blade Guard

Fit the blade guard to the shoulder of the grinder, ensuring it is fully located. Turn the guard so that the open end is facing away, i.e. the opposite end to the handle,

then nip up the securing nut.

2. Mounting the Grinding Wheel/Cutting Disc.

WARNING!

ALWAYS check to ensure the machine is disconnected from the mains supply, and that the grinding disk is suitable for the application in hand. The disk supplied with this machine is suitable for grinding steel.

Consult your Clarke dealer if you need a disk for cutting or grinding other materials...such as masonry etc.

Check also that the maximum RPM, marked on the disk exceeds 6000RPM.

2.1 Unscrew and remove the outer flange. If it is tight, lock the spindle by pressing

theSpindle Lock button (see Fig.3) and use thetool supplied to turn the flange to break theseal. It may then be screwed off by hand.

2.2 The Grinding wheel supplied is a

‘Depressed Centre’ type, mount it as shown in the Fig.1, i.e. with the depressed centre towards the motor.

2. 3 Ensuring the wheel sits snugly over the raised

boss on the inner flange, screw on the outer flange with the centre boss facing inwards.

Tighten the flange using the tool provided, locking the spindle by pressing the Spindle Lock button, and taking care to ensure the wheel is still sitting snugly, centred over the flange bosses. Care should be taken also NOT to overtighten the outer flange.

WARNING! NEVER use reducing bushes or adapters to adapt large bore abrasive wheels

2.4 Finally, rotate the disk by hand to ensure that does not foul the guard. If it

does, determine the cause and rectify before plugging in to a power supply.

Important:

Fig .2 shows the set up for a grinding wheel.

When attaching a cutting disk, YOU MUST REVERSE the Outer flange.

Fig 2.

4. Keep the mains cable well away from the tool and ensure an adequate electrical supply is close at hand so that the operation is not restricted by the length of the cable.

5. Switch the tool OFF immediately the task is completed and be aware that the wheel/disc will continue to rotate for a period of time after switching off.

6. NEVER allow the ventilation slots in the tool to become blocked.

7. DO NOT attempt any electrical repair yourself. Consult a qualified electrician, or our Service Dep’t on 020 8988 7400

8. DO NOT cut through walls or cavities before checking for hidden electrical wires or water pipes etc.

9. Ensure the grinding wheel or cutting disc is fully tightened before use.

10. Do not use the tool in a confined space which may limit body movement.

11. Ensure the wheel/disc is not touching the work when switching ON.

12. Use only wheels/discs having a maximum operating speed of at least 6,000RPM.

13. Check the disk carefully for cracks or damage before operation. Replace cracked or damaged wheels/discs immediately.

14. Take care not to damage the spindle or wheel flanges as damage to these parts could result in wheel/disc breakage.

15. The angle grinder will ‘kick’ as it starts, so hold it firmly with both hands, away from your body, when switching on.

16. Before using the tool on an actual workpiece, allow it to run briefly, checking for vibration which could indicate poor balance or installation of the wheel/ disc.

17. Use only wheels/discs designed for their specific function. DO NOT use cutting discs for grinding metal, or metal grinding wheels for cutting masonry.

18. Ensure tha wheel dimensions are compatible with the grinder.

19. ALWAYS follow the grinding wheel manufaturers recommendations for use and store the wheels according to manufacturers instructions.

20. Beware of flying sparks. Keep clothing and other flammable materials well away from flying sparks as fires could start after a short delay.

21. NEVER use excessive force. It should only be necessary to use a little more than the weight of the tool. If the rotational speed drops abnormally, reduce pressure immediately. Forcing the tool and excessive pressure can cause dangerous disc breakage and/or damage to the tool.

22. NEVER use the tool with the guard removed. If the guard becomes damaged, it should be replaced

Additionally, ALWAYS keep these instructions in a safe place for future reference.
