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

tool’s 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, and are

NOT safety glasses.

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

7. DON’T 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 an explosive atmosphere (near 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 into 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 Guard against electric shock. Avoid body contact with earthed or grounded

surfaces (e.g. Pipes, Radiators, Ranges, Refrigerators).

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.

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.

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

the Clarke Service Department on 0208 988 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 11,000RPM.

13. Check the disc 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. ALWAYS hold the tool firmly in BOTH hands.

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. When grinding, hold the grinder at an angle of 15-30Oto the work surface.

19. 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.

20. NEVER use the tool with the guard removed. If the guard becomes damaged,

it should be replaced.

21. NEVER twist the grinder when using Cutting Discs. Take care to ensure sparks

do not fall on to sensitive areas. Be aware of the fire risk from sparks.

22. Never use Wheels/Discs other than 115mm diameter.

23. ALWAYS store and handle abrasive discs according to the manufacturer’s

instructions. 5

When pressed, this button, located on top

of the head, is used to lock the spindle

when attempting to unscrew and remove the outer flange (using the special tool

provided), in order to mount or change the grinding wheel or cutting disc.

The blade guard can be rotated about its axis

and is locked by a single hex head screw (see

Fig.3). Slacken the screw, using the tool supplied,

grasp the guard firmly and move to the desired

position, ensuring maximum protection for the

operator without impeding the work being

carried out. The screw must be tightened when

the guard is in the desired position.

NOTE: When the tool is new, it may be necessary

to slacken the three cross head screws, in

addition to the securing screw, in order to free

off the guard. This can only be achieved with

the cutting disc removed. Once the guard has

been moved, the three screws must be retightened, and should not require slackening

for this purpose again. Before fitting the cutting disc, try moving the guard again ensuring

only the locking screw is loose, then with the guard in the desired position, retighten the

locking screw.

The hand holding the tool body will control the ON/OFF trigger switch, whilst the other

hand grasps the hand grip and guides the tool over the workpiece.

Hold the tool firmly but not tightly. Allow the tool to do the work...DO NOT force the wheel

on to the workpiece.

The ON/OFF trigger switch (A) in Fig 1, is provided with a safety lock button (B), to

prevent accidental starting. To operate, fully depress the trigger switch and depressing
