GENERAL SAFETY RULES

WORK ENVIRONMENT

1. Keep the work area clean, tidy and well lit. Cluttered and dark areas invite

accidents

2. Do not operate power tools in explosive atmospheres, such as in the

presence of flammable liquids, gases or dust. Power tools create sparks

which may ignite the dust or fumes.

3. Keep children and bystanders away while operating a power tool.

Distractions can cause you to lose control.

PERSONAL SAFETY

1. Stay alert, watch what you are doing and use common sense when

operating a power tool. Do not use a power tool while you are tired or

under the influence of drugs, alcohol or medication. A moment of

inattention while operating power tools may result in personal injury.

2. Avoid accidental starting. Ensure the switch is in the off position before

plugging in. Plugging in power tools that have the switch on invites

accidents.

3. Do not overreach. Keep proper footing and balance at all times. This

enables better control of the power tool in unexpected situations.

4. Dress properly. Do not wear loose clothing or jewellery. Keep your hair,

clothing and gloves away from moving parts. Loose clothes, jewellery or

long hair can be caught in moving parts.

5. Gloves, manufactured to the current European safety standards should be

worn when operating grinding equipment.

6. Eye protection manufactured to the current European safety standards

should be worn when operating grinding equipment. Eye protectors must

provide protection from flying particles from the front and the side.

GENERAL USE AND CARE OF POWER TOOLS

1. ALWAYS check for any damage or condition that could affect the

grinder’s operation. Any damaged part should be properly repaired.

2. NEVER use the grinder if it is defective or operating abnormally.

CAUTION: FAILURE TO FOLLOW THESE PRECAUTIONS COULD RESULT IN

PERSONAL INJURY, AND/OR DAMAGE TO PROPERTY.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

3. NEVER abuse the mains cable. Never yank the cable to disconnect it from

the socket. Keep the cable away from sharp edges/hot surfaces.

4. NEVER carry out any alterations or modifications to this product.

5. NEVER wipe the sharpener clean with solvents. Wipe plastic parts with a

soft cloth, slightly dampened with soapy water.

6. NEVER attempt any repairs yourself. If you have a problem with this product

contact your local CLARKE dealer.

7. Do not use the tool for any purpose than that described in this manual.

8. Always maintain the tool with care. Keep it clean for the best and safest

performance.

9. Do not force the power tool. Use the correct power tool for your

application. The correct power tool will do the job better and safer at the

rate which it was designed.

10. Do not use the power tool if the switch does not turn it on and off. Any

power tool that cannot be controlled with the switch is dangerous and

must be repaired.

11. Store idle tools out of the reach of children and do not allow persons

unfamiliar with the power tool or these instructions to operate the power

tool. Power tools are dangerous in the hands of untrained users.

12. Maintain power tools. Check for misalignment or binding of moving parts,

breakage of parts and any other condition that may affect the power

tools operation. If damaged, have the power tool repaired before use.

Many accidents are caused by poorly maintained power tools.

13. Use the power tool and accessories in accordance with these instructions

and in the manner intended for the particular type of power tool, taking

into account the working conditions and the work to be performed. Use of

the power tool for operations different from intended could result in a

hazardous situation.

ELECTRICAL SAFETY

1. Power tool plugs must match the outlet. Never modify the plug in any way.

Do not use adapter plugs with earthed (grounded) power tools. Correct

plugs and matching outlets will reduce the risk of electric shock.

2. Do not abuse the cable. Never use it for carrying, pulling or unplugging the

power tool. Keep the cable away from heat, oil, sharp edges or moving

parts. Damaged or entangled cables increase the risk of electric shock.

3. Do not expose power tools to rain or wet conditions. Water entering a

power tool will increase the risk of electric shock. If operating the power

tool in a damp location is unavoidable, use a residual current device

(RCD) protected supply.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

4. When operating a power tool outdoors, use an extension cable suitable for

outdoor use. Use of a cable suitable for outdoor use reduces the risk of

electric shock.

GRINDING STONE SAFETY

1. Check the speed of the grindstone before fitting to your grinder. Never use

a stone with a rpm speed less than the rpm speed of your grinder. See

specification.

2. The outside diameter and thickness of your accessories must be within the

capacity rating of the power tool. The correct size accessories can be

correctly guarded and controlled.

3. Never use a stone that is chipped, cracked or damaged. Fragments from

a broken or damaged grinding stone can cause serious injury. Make sure

that defective stones are destroyed and not used.

4. Bonded abrasive products are breakable and shall therefore be handled

with utmost care. The use of damaged or improperly mounted or used

abrasive products is dangerous and can cause serious injuries.

5. Always refer to the label for specified usage and observe the safety

information. Do not use for purposes other than specified.

6. Always use the correct stone for it’s intended task. Using the incorrect stone

can cause serious injury.

7. Allow the stone and tool to do the work. Never force the workpiece

against the stone as this could cause kickback and/or shatter the stone

causing serious injury.

8. Do not use separate reducing bushes or adapters to adapt large hole

abrasive wheels. Do not force a stone onto a machine or alter the size of

the arbor hole.

9. Never use a damaged grinding stone. Inspect the stone before each use

for chips, cracks or excess wear. If the tool or accessory is dropped, inspect

for damage or install a new accessory. After fitting the accessory, position

yourself away from the plane of the rotating accessory and run the tool at

full speed. damaged stones may break apart during this test.

10. Abrasive products shall be handled and transported with care. Abrasive

products shall be stored in such a manner that they are not subjected to

mechanical damage and harmful environmental influences.

BENCH GRINDER SAFETY WARNINGS

1. Hold a hand tool or blade being sharpened firmly to prevent loss of control.

2. Never install a abrasive flap wheel or sanding disc on this grinder.

3. Always replace a cracked grinding wheel immediately.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

4. Never use damaged or incorrect grindstones. The stone and retaining

fixtures were specially designed for your grinder, for optimum performance

and safety of operation. Inspect the condition of the grinding stone before

use and do not use if any damage is found.

5. Always use the tool rests to steady the workpiece, the torque of the

spinning grinding wheel may pull the workpiece from your hands.

6. ALWAYS check for damaged parts. Before further use any part that is

damaged should be carefully checked to determine if it would operate

properly and perform its intended function. Check for misalignment or

binding of moving parts, breakage of parts and any other condition that

may affect the tool's operation. A part that is damaged should be properly

repaired or replaced at an authorised service center. Following this rule will

reduce the risk of electric shock, fire or serious injury.

NOTE: Bench grinders used in industrial environments may be subject to

the requirements of The Provision and Use of Work Equipment

regulations 1992 (particularly regarding the training requirement

of The Abrasive Wheels Regulations 1970), or other legislation. If in

doubt seek advice.

Please keep these instructions in a safe place for future reference.

ASSEMBLY & INSTALLATION

1. Fix the grinder to the bench using

suitable screws or bolts through

the holes In the grinder base. Do

not overtighten the securing

screws.

2. The grinder has rubber mounting

feet to help minimise vibration,

and these will not be effective if

compressed too tightly. If using

bolts, make sure they will not work

loose under vibration by fitting

locknuts.

3. Fit the guard visor as shown in the illustration. Position the visor mounting

bracket to within 1.5mm (1/16") of the wheel.

4. Fit the work rest as shown in the illustration, positioning it to within 1.5mm (1/

16") of the wheel. This will help to prevent the workpiece being dragged

between the wheel and the work rest.

5. Rotate the wheel by hand to make sure the visor mounting bracket and

work rest are clear of the wheel.

6. Any fault which might lead to fracture in a new grinding wheel is likely to

show in its first minute of operation. Switch the grinder on, stand clear, and

allow the grinder to run for a minute or so before using it for the first time.

USING YOUR GRINDER

1. Switch on and allow the grinder to reach full speed, then hold the tool

firmly on the tool rest and apply slight pressure on to the grinding wheel,

allowing the grinder to do the work.

WARNING: FRAGMENTS FROM A BROKEN/DETACHED GRINDING WHEEL

CAN CAUSE INJURY.

WARNING: THE STONE WILL CONTINUE TO ROTATE BRIEFLY AFTER THE OFF

SWITCH HAS BEEN PRESSED.

WARNING: WARNING: APPLYIING EXCESSIVE FORCE TO THE GRINDING

WHEEL CAN BE DANGEROUS AND COULD CAUSE DAMAGE TO THE

MACHINE. NEVER ATTEMPT TO USE THE SIDE OF THE GRINDING WHEEL.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

NOTE: Never attempt to grind a piece of metal that is thinner than the

gap between the tool rest and the grinding wheel.

2. Press the tool blade evenly onto the grinding stone and move the tool

sideways across the stone. Make sure that at least half the width of the tool

cutting edge comes into contact with the grinding stone at any time to

avoid damage to the stone.

MAINTENANCE

GENERAL MAINTENANCE

Make sure that all components are tight and secure. Always have any

damaged or worn parts repaired or replaced by qualified service personnel.

Do not attempt to repair the grinder unless you are qualified to do so.

The drive motor and bearings are sealed units and require no regular

maintenance. Should you require assistance, contact your local Clarke

service agent.

The stone will wear down with use and may well go out of true. Use a dressing

wheel or stone grader to correct the trueness and to remove worn, glazed

grains from the stone.

The stone will have a finite life expectancy, dependant upon the nature of the

work being done. Periodically, make a note of the wheel diameter and

replace your 150mm dia wheel if it reduces to an little as 130mm in diameter.

INSTALLING A NEW GRINDING WHEEL

Use only correct replacement wheels of a suitable grade for your intended

use. Check that the spindle speed (no-load speed) marked on the machine

does not exceed the maximum rpm marked on the grinding wheel. Consult

your dealer if in doubt about choosing the correct replacement wheel.

Check replacement wheels thoroughly for any signs of damage before fitting.

Replacement wheels must fit easily, but not loosely, on to the machine spindle.

Do not attempt to fit a wheel that is tight on the spindle. There is a danger of a

tight fitting wheel bursting in use if the spindle expands due to becoming hot.

WARNING: NEVER RE-START THE GRINDER WITHOUT THE GUARDS

INSTALLED.
