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 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 a 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.

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 center. 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.
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
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.

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).

1. Fix the tool rest to the bench
grinder with the hand knob and
washer as shown.
• The tool rest is adjustable and
should be positioned 1.5 mm
from the grinding wheel.
• Ensure that the tool rest is firmly
fixed and horizontal.
INSTALLING THE SPARK DEFLECTOR (GRINDING WHEEL ONLY)
Fit the spark deflector to the wheel
guards using the screws provided.

OPERATION
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
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 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 (if grinding). Hold very small
pieces with pliers or other suitable clamps.
3. Feed the work piece smoothly and evenly against the 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.
• The wire wheel can be used to remove paint and rust. Always wear
a dust mask when removing paint or rust.
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 to a suitable position.
