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. Water entering a
power tool will increase the risk of electric shock.
3. Do not abuse the 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: [email protected] or [email protected]
Page 5
2. Use personal protective equipment. Always wear eye protection. Safety
equipment such as dust mask, non-skid safety shoes, hand 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.
6. Dress properly. Do not wear loose clothing or jewellery.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. Avoid operator fatigue. Stop the power tool at regular intervals for a short
break to rest hands and arms.
14. 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 duty 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 your 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 centre.

12. Accessories. Only use the recommended accessories. Ensure that the discs
are fitted in accordance with the manufacturer’s instructions.
13. Only use discs that comply with EN12413 or EN13236. Make sure that the
disc used is suitable for the no load speed of the angle grinder. See
Specifications on page 16. Check that the speed marked on the disc is
compatible with the grinder. Check that discs are specifically for hand held
angle grinder use.
14. Sparks and particles. Ensure that sparks and particles resulting from use do
not create a hazard, use screens where appropriate.
15. Personal protective equipment. Always use protective safety glasses and
dust mask. Use other protective equipment such as gloves, apron and
helmet where necessary. If working at floor level, always wear knee pads.
16. Switching off. The disc will continue to rotate for a few seconds after the
angle grinder is switched off. Always wait until the disc has completely
stopped before putting the angle grinder down.
17. Use the disc guard. Do not use the angle grinder without the disc guard.
Make sure that the guard is securely fitted and positioned for maximum
safety before operating the angle grinder. Always use the correct guard for
cutting or grinding work as described in this manual.
18. The grinding surface of depressed centre discs must be mounted below
the plane of the guard lip. An improperly mounted discthat projects above
the plane of the guard lip cannot be adequately protected.
19. Holding the angle grinder. Always hold the angle grinder with both hands.
Ensure that the workpiece is kept at waist height where possible. Never use
the angle grinder between the legs whilst sitting on the floor.
20. Feed direction. For cutting, always feed the disc into the work so that an
upcutting action is achieved.
21. Spindle lock. Do not operate the spindle lock while the spindle is still
spinning.
22. Beware of kickback. Always take care to avoid kickback by maintaining a
firm grip of the tool and positioning your body and arm to resist kickback
forces. Always use the auxiliary handle for maximum control.
23. Avoid moving parts. Never position your hand close to the rotating parts
and take special care when working in corners or with sharp edges, or any
situation where the disc could snag.

the wrong disc can cause serious injury.
7. Using the disc. Allow the disc and tool to do the work. Never force the disc
onto the workpiece as this could cause kickback and/or shatter the disc
causing serious injury. Kickback can occur in the event of a disc jam.
8. Cutting discs. Do not use cutting discs for side grinding. Do not put
sideways pressure on cutting discs.
9. Do not use reducing bushes. Do not use separate reducing bushes or
adapters to adapt large hole abrasive discs. Do not force a disc onto a
grinding machine or alter the size of the arbor hole.
10. Never use a damaged disc. Inspect each disc before each use for chips,
cracks, excess wear. If the tool or accessory is dropped, inspect for
damage or install a new accessory. After fitting the accessory, position
yourself away from the plane of the rotating accessory and run the tool at
full speed. damaged discs are likely to break apart during this test.
11. Handling and storing discs. Abrasive products shall be handled and
transported with care. Abrasive products shall be stored in such a manner
that they are not subjected to mechanical damage and harmful
environmental influences.
12. Always use suitable mounting discs. Ensure they are of the correct size and
shape for your cutting or grinding disc to support the disc and reduce the

• Do not subject the cutting disc to sideways pressure.
14
Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]
Page 15
• 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.
• Whenever a new disc has been fitted, always run the grinder at no
load speed to check for irregularities before starting work.
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.
