GENERAL SAFETY RULES
CAUTION: FAILURE TO FOLLOW THESE PRECAUTIONS COULD RESULT IN
PERSONAL INJURY, AND/OR DAMAGE TO PROPERTY.
WORK ENVIRONMENT
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. Anyone
entering the work area must wear personal protective equipment.
Distractions can cause you to lose control and fragments of work or a
broken disc may fly away and cause injury.
4. Store power tools properly when not in use. Abrasive products should be
stored in a dry, secure place out of the reach of children
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 or use discs that require liquid lubricants. Water entering a power tool will increase the risk of
electric shock.
3. Do not abuse the power cable. Never use the cable 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.
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.
4
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com
2. Use personal protective equipment. Always wear eye protection. Safety
equipment such as dust mask, non-skid safety shoes, hearing protection
and a workshop apron capable of stopping small abrasive or workpiece
fragments.
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 adjusting key or wrench before turning the power tool on. A
wrench or a key left attached to a rotating part of the power tool 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. Dress properly. Do not wear loose clothing or jewellery.
6. Keep your hair, clothing and gloves away from moving parts. Loose
clothes, jewellery or long hair can be caught in moving parts.Keep the
work area clean and tidy.
7. This tool vibrates with use. Vibration may be harmful to your hands or arms.
Stop using the tool if discomfort, a tingling feeling or pain occurs. Seek
medical advice before resuming use.
8. Hold the power tool by insulated gripping surfaces only, when performing
an operation where the cutting tool could contact hidden wiring or its own
cable. Contacting a live wire may make exposed parts of the power tool
live and give the operator an electric shock.
9. Never lay a power tool down until it has come to a complete standstill. The
rotating accessory may grab the surface and pull the tool out of your
control.
10. Do not run the power tool while carrying it at your side. Accidental contact
with a spinning accessory could snag on clothing and pull the tool to your
body.
11. Regularly clean the power tool’s air vents. The motor fan will draw dust
inside the housing and accumulation of material could cause electrical
hazards.
12. Avoid operator fatigue. Stop the power tool at regular intervals for a short
break to rest hands and arms.
13. Maintain your tools. Keep all handles and grips dry and clean.

ANGLE GRINDER SAFETY INSTRUCTIONS
1. Before starting work, always consider the following: The use of hand held
angle grinders for grinding and cutting operations can present risks to the
user. Full observation of the safety instructions in this user guide is essential.
2. Before undertaking grinding or cutting operations, always consider the following: Is the grinding/cutting work necessary? Could a different tool be
used with less risk? (e.g. a fixed controlled cutting/grinding machine). Can
the work be sensibly positioned, secured and accessed so the operator
can maintain adequate control of the tool, taking into account, for
example the possible hazards associated with potential snatch/jamming of
a cutting disc. Is the cutting task too large for a hand held tool? If in doubt,
use an alternative lower risk solution or refer to qualified trade personnel.
3. Always use the correct tool for the job. Always assess the job. You should
never force a small angle grinder to do the job of a heavy tool. Do not use
tools for purposes not intended.
4. Always position the power cable clear of the spinning disc. If you loose
control, the cable may be cut or snagged and you hand drawn onto the
spinning disc.
5. Start up speed. Always allow the angle grinder to run up to full operating
speed before applying it to the job.
6. Applying the disc to the workpiece. Never bump the angle grinder disc on
the workpiece, or let the disc hit any other objects while grinding.
7. Do not abuse the mains lead. Never carry the tool by the mains lead or pull
it to disconnect it from the mains socket. Keep the mains lead away from
heat, oil and sharp edges.
8. Secure the work. Use clamps, or vices to hold the workpiece. Failure to
secure the workpiece could result in serious injury.
9. 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.
10. Use outdoor extension leads. When the tool is used outdoors, only use
extension leads intended for outdoor use. Always make sure that the
extension lead is correctly rated.
11. Check damaged parts. A guard or other parts that are damaged should
be properly repaired or replaced, by an authorised service centre, unless
otherwise indicated in this user guide. Have defective switches replaced
by an authorised service facility.

• Do not force the disc through the material. Work with a feed rate
that is suited to the material being cut.
• Do not subject the cutting disc to sideways pressure.
• The direction of the cutting motion is important. Always feed the
cutting disc into the work so that it cuts in an upward direction. If you
do not do this It can result in the disc climbing out of the cut in an
uncontrolled manner and may lead to loss of control or serious injury.
GRINDING TIPS
WARNING: WHEN GRINDING, ONLY USE DISCS SPECIFICALLY DESIGNED
FOR GRINDING. YOU MUST NEVER USE CUTTING DISCS TO GRIND ANY
MATERIAL.
• The key to efficient grinding is to control the pressure and surface
contact between the grinding disc and the workpiece.
• Flat surfaces are ground at an acute angle, usually 15 to 30 degrees
to the workpiece. Too great an angle causes concentration of
pressure on a small area which may gouge, or burn the workpiece.
• Allow the disc to reach full speed before grinding.
• Avoid overloading the angle grinder. If it becomes hot when being
used, allow it to run for a few minutes under no-load conditions.
