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 adapter 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 power cable. Never use it for carrying, pulling or unplugging the
power tool. Keep the power 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 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 rests to steady the workpiece. If the rests 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 grinder and unplug it before leaving.
8. ALWAYS check for damaged parts. Before further use of the grinder, 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 you local CLARKE
service department. Following this rule will reduce the risk of electric shock,
fire or serious injury.
9. Eye protection manufactured to the current European safety standards
should be worn when operating grinding equipment.
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.

BEFORE USE
INSTALLING THE TOOL RESTS
1. Fix the tool rests in place with the
thumb screw as shown.
• The tool rests are adjustable
and should be positioned less
then 2 mm from the grinding
wheels.
• Ensure that the tool rest is firmly
fixed and horizontal.
INSTALLING THE SPARK DEFLECTORS / EYE SHIELDS
Fit the spark deflector / eye shields to
the wheel guards using the screws
provided.
• Adjust the spark deflector to
compensate for wear of the
wheel. Keep the distance
between the spark deflector
and wheel as small as possible
and never more than 2 mm.
NOTE: Adjust the eye shields to an
appropriate distance from the tool rests avoiding interference during
operation.
BLADE SHARPENING TIPS
SCISSORS
If possible, take scissors apart to make the sharpening operation easier and
safer. Remove material only from the outside surface and work from the heavy
end of the blade toward the tip.
KNIVES
Remove metal from both faces of most knives, working from the large end of
the blade toward the tip.

OPERATION
NOTE: Check that there is approx a 1.5 mm clearance between the tool rest
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 wheels reach full speed before use.
• 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. Press the workpiece smoothly and evenly against the grinding wheel.
4. Always keep the workpiece 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 tools/workpieces to become hot. Take
care when handling hot items.
5. Switch the bench grinder off using the on/off switch when you have
finished.
DRESSING THE GRINDING WHEEL
The grinding wheel may need dressing occasionally. Only dress the wheel with
a proper dressing tool whilst wearing safety goggles or glasses. If in doubt seek
professional advice. Dressing tools are available from your CLARKE dealer.
