GENERAL SAFETY WARNINGS
WARNING
When using electric tools, basic safety precautions
should always be followed to reduce the risk of re,
electric shock and personal injury. Read all these
instructions before attempting to operate this product
and save these instructions.
■Keep work area clear. Cluttered areas and benches
invite injuries.
■Consider work area environment. Do not expose
tools to rain. Do not use tools in damp or wet locations.
Keep work area well lit. Do not use tools in the presence
of flammable liquids or gases.
■Guard against electric shock. Avoid body contact with
earthed or grounded surfaces (e.g., pipes, radiators,
ranges, refrigerators).
■Keep other persons away. Do not let persons,
especially children, be involved in the work, touch the
tool or the extension cord, and keep them away from
the work area.
■Store idle tools. When not in use, tools should be
stored in a dry locked-up place, out of reach of children.
■Do not force the tool. It will do the job better and safer
at the rate for which it was intended.
■Use the right tool. Do not force small tools to do the
job of a heavy duty tool. Do not use tools for purposes
not intended, for example, do not use circular saws to
cut tree limbs or logs.
■Dress properly. Do not wear loose clothing or
jewellery, they can be caught in moving parts. Non-
skid footwear is recommended when working outdoors.
Wear protective hair covering to contain long hair.
■Use protective equipment. Use safety glasses. Use
face or dust mask if working operations create dust.
■Connect dust extraction equipment. If the tool is
provided for the connection of dust extraction and
collecting equipment, ensure these are connected and
properly used.
■Do not abuse the cord. Never yank the cord to
disconnect it from the socket. Keep the cord away from
heat, oil and sharp edges.
■Secure work. Where possible, use clamps or a vice to
hold the work. It is safer than using your hand.
■Do not overreach. Keep proper footing and balance
at all times.
■Maintain tools with care. Keep cutting tools sharp
and clean for better and safer performance. Follow
instruction for lubricating and changing accessories.
Inspect tool cords periodically and if damaged, have
them repaired by an authorized service facility. Inspect
extension cords periodically and replace if damaged.
Keep handles dry, clean and free from oil and grease.
■Disconnect tools. When not in use, before servicing
and when changing accessories such as blades, bits
and cutters, disconnect tools from the power supply.
■Remove adjusting keys and wrenches. Form the
habit of checking to see that keys and adjusting
wrenches are removed from the tool before turning it
on.
■Avoid unintentional starting. Ensure switch is in “off”
position when plugging in.
■Use outdoor extension leads. When the tool is used
outdoors, use only extension cords intended for outdoor
use and so marked.
■Stay alert. Watch what you are doing, use common
sense and do not operate the tool when you are tired,
under the influence of any drugs, alcohol, or medication
that could affect your ability to use the tool properly.
■Check damaged parts. Before further use of tool, it
should be carefully checked to determine that it will
operate properly and perform its intended function.
Check for alignment of moving parts, binding of moving
parts, breakage of parts, mounting and any other
conditions that may affect its operation. A guard or
other part that is damaged should be properly repaired
or replaced by an authorized service centre unless
otherwise indicated in this instruction manual. Have
defective switches replaced by an authorized service
centre. Do not use the tool if the switch does not turn
it on and off.
■Warning. The use of any accessory or attachment
other than the one recommended in this instruction
manual may present a risk of personal injury.
■Have your tool repaired by a qualified person. This
electric tool complies with the relevant safety rules.
Repairs should only be carried out by qualified persons
using original spare parts otherwise this may result in
considerable danger to the user.
SPECIAL SAFETY RULES
■The plug must be plugged into a matching outlet that is
properly installed and grounded in accordance with all
local codes and ordinances. If you are not sure, have a
certified electrician check the receptacle.
■Mount the bench grinder firmly to the workbench,
grinding stand or other rigid frame before operation.
An unsecured bench grinder is unstable and will move
during operation. This may result in damage or injury.
■Prior to operation, inspect the components and any
accessories of the bench grinder to ensure there are
no conditions that may affect proper operation. Tighten
grinding wheel lock nuts, securing bolts and all clamps
and guards.
■Prior to each start up, inspect the grinding wheel for
damage. Do not use damaged or unshaped wheels.
Replace any damaged grinding wheel according to the
instructions.
■Check that the wheel rotates freely prior to each start
up. With the bench grinder unplugged and the switch

turned to OFF, carefully spin the wheel by hand. The
wheel should not contact any components of the
bench grinder, and there should be no binding or other
conditions that may affect proper operation.
■During each start-up, stand to one side of the grinder
and switch it ON. Let the grinder operate at full speed
for one minute so that any undetected flaws or cracks
of the wheel will become apparent. Do not contact the
wheel with the work piece until the bench grinder has
reached full speed.
■Secure work. Use clamps or a vise to hold the work
when practical. It is safer than using your hand and it
frees both hands to operate the tool.
■Keep hands and body parts clear of grinding wheels.
Contacting the rotating wheel may cause injury.
■Always use guards and eye shields. Keep all guards in
place and in working order. Operating the bench grinder
without guards or with damaged guards may result in
injury.
■Avoid burns. Grinding may cause items and the grinding
wheel to become hot. Do not touch the grinding wheel
or items that may be hot.
■Do not use the grinder to work on small items or items
which cannot be held properly. The item may be thrown
and result in injury.
■Never grind on the side of the wheel. The wheel will
shatter. Grind on the face of the wheel only.
■Never leave a running tool unattended. Turn the power
switch to OFF. The grinding wheels continue to rotate
after the tool is switched off. Do not leave the tool until
it has come to a complete stop.
■Never reach behind or beneath the grinding wheels.
■Use ear protection, such as plugs or muffs, during
extended periods of operation.
■The vibration emission during actual use of power tool
can differ from the declared total value depending on
the ways in which the tool is used. Operators need to
identify safety measures to protect themselves based
on an estimation of exposure in the actual conditions
of use.
■Remove the plug before carrying out any adjustment,
servicing or maintenance. The power cord must remain
unplugged whenever you are maintaining your bench
grinder.
■Adjust tool rests whenever necessary to keep the
distance between the work rests and the grinding
wheels as small as possible. This distance shall be less
than or equal to 2 mm in any case. As the diameter
of the grinding wheel decreases with use, maintain the
maximum tool rest distance by adjusting it.
■Adjust spark arrestors whenever necessary to keep
the distance between the work rests and the grinding
wheels as small as possible. This distance shall be less
than or equal to 2 mm in any case. As the diameter
of the grinding wheel decreases with use, maintain the
maximum spark arrestor distance by adjusting it.
■Replace grinding wheel when its diameter wear value
is more than 8mm.
■Replace work rest when its thickness wear value is
more than 0.5 mm.
■When fitting a new grinding wheel, always check that
the stated maximum RPM meets or exceeds that stated
on the grinder. Ensure the wheel diameter and arbor
size meet that stated on the specifications. Also check
the new wheel for damage, such as flaws or cracks.
INTENDED USE
■This bench grinder is ideal for use in sharpening
chisels, axes and other wood-cutting tools. It is also
useful for repairing tips on screwdrivers and drill bits
or for removing excess metal burrs from pieces of cut
metal.
■With the proper accessories, this tool can be used for
cleaning metal surfaces using a wire brush or for buffing
and polishing using a cloth wheel.
■Never use this bench grinder for cut-off operations.
