POWER TOOL SAFETY WARNINGS

1) WORK AREA

1. Keep the work area clean 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.

2) ELECTRICAL SAFETY

1. Power tool plugs must match the outlet. Never modify the plug in any way. Do not

use adaptor plugs with earthed (grounded) power tools. Unmodified plugs and

matching outlets will reduce the risk of electric shock.

2. Do not expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electric shock.

3. 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.

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.

5. If operating the power tool in a damp location is unavoidable, use a residual current

device (RCD) protected supply.

3) 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. Use safety equipment. Always wear eye protection. Safety equipment such as dust

mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate

conditions will reduce personal injuries.

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

Carrying power tools with your finger on the switch or plugging in power tools that

have the switch on invites accidents.

4. Remove any wrench before turning the power tool on. A wrench left attached to a

rotating part may result in personal injury.

5. Do not overreach. Keep proper footing and balance at all times. This enables better

control of the power tool in unexpected situations.

6. 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.

4) POWER TOOL USE AND CARE

1. Do not force the power tool. Use the correct accessories for your application. The

correct power tool will do the job better and safer at the rate which it was designed.

2. 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.

3. Disconnect the plug from the power source before changing accessories, or storing

power tools. Such preventive safety measures reduce the risk of starting the power

tool accidentally.

4. Store idle tools out of the reach of children and do not allow persons unfamiliar with

the power tool or these instructions to operate it. Power tools are dangerous in the

hands of untrained users.

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

of parts and any other condition that may affect the power tool’s operation. If

damaged, have the power tool repaired before use. Many accidents are caused

by poorly maintained power tools.

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

manner intended, 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.

7. The performance of this tool may vary, depending upon variations in line voltage.

Extension cable usage may also affect performance.

5) SERVICE

1. Have your power tool serviced by qualified service personnel using only identical

replacement parts. This will ensure that the safety of the power tool is maintained.

BENCH GRINDER SAFETY WARNINGS

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

2. NEVER install an abrasive flap wheel or sanding disc on this grinder.

3. Always replace a cracked grinding wheel immediately.

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

5. Do not use aluminium oxide wheels when grinding non-ferrous metals such as

aluminium or brass. Use silicon carbide wheels (not included) for grinding non-ferrous

metals.

6. Always use the tool rests to steady the workpiece. If the tool attachments are not

used, the torque of the spinning grinding/polishing wheel may pull the workpiece

from your hands.

7. Never leave the grinder unattended when it is connected to an electrical power

supply. Switch off the machine and unplug it before leaving.

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

8. ALWAYS check for damaged parts. Before further use of the tool, a guard or other

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 centre. Following this rule will reduce the risk of electric shock, fire

or serious injury.

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

when operating grinding equipment.

10. Eye protection manufactured to the current European safety standards should be

worn when operating grinding equipment.

11. Eye guards supplied with the machine must be used at all times.

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.

BEFORE USE

MOUNTING THE GRINDER ON A WORKBENCH

NOTE: We highly recommend that you bolt this bench grinder securely to a

workbench to gain maximum stability for your machine.

1. Using the base of the bench

grinder as a template, mark the

bench through the holes in the

casting.

2. Bolt the bench grinder to the

bench with bolts, washers and nuts

(not supplied).

3. To reduce vibration, mount the

bench grinder on a vibration

absorbing mat.

INSTALLING THE TOOL RESTS

1. Fix the tool rests to the bench

grinder with the screw and hand

knob as shown.

• The tool rests are adjustable

and should be positioned 1.5

mm from the grinding wheels.

• Ensure that the tool rest is firmly

fixed and horizontal.

• One of the tool rests has an

angled groove to allow you to sharpen the ends of drill bits.

INSTALLING THE SPARK DEFLECTORS

Fit both the spark deflectors to the

wheel guards using the screws

provided.

• Adjust the spark deflector

frequently to compensate for

wear of the wheel, keep the

distance between the spark

deflector and wheel as small as

possible and never more than

2mm.

the bench grinder using the

bracket, flat washer and bolt

supplied.

2. Fit the lens to the lens holder as

shown.

NOTE: One of the lenes has a

manifying window.

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

OPERATION

NOTE: Check that there is a 1.5 mm clearance between the tool rests and the

surface of the grinding wheel. Adjust as necessary.

NOTE: Check the gap between the spark deflectors and the surface of the

grinding wheel. These should also be a maximum of 2 mm. Adjust as

necessary.

NOTE: Check that the eyeshields have been secured in the correct position

and that the grinding wheel lock nuts are tight.

1. Stand to the side of the bench grinder and switch it on using the on/off

switch.

• Let the grinding wheel reach full speed before grinding.

• The wheel rotates in the same direction as the arrow stamped in the

side of the wheel guard.

2. Hold the work piece firmly against the tool rest. Hold very small pieces with

pliers or other suitable clamps.

3. Feed the work piece smoothly and evenly against the grinding wheel.

4. Always keep the work piece moving across the face of the wheel. Grinding

against the same part of the wheel will cause uneven wear of the wheel

face.

• Grind only on the face of the grinding wheel and never the side of it.

NOTE: Prolonged grinding will cause most tools to become hot. Use care

when handling hot tools.

5. Switch the bench grinder off using the on/off switch when you have

finished.

USING THE BUILT IN LIGHT

The built in light will come on automatically whenever the bench grinder is

switched on.

The arm can bend to set the light in a suitable position.

CAUTION: KEEP ALL BYSTANDERS A SAFE DISTANCE AWAY FROM THE

TOOL AND NOT IN DIRECT LINE, FRONT OR BACK OF THE GRINDER.

CAUTION: ALWAYS WEAR SAFETY GLASSES
