GENERAL SAFETY RULES
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.
CAUTION: FAILURE TO FOLLOW THESE PRECAUTIONS COULD RESULT IN
PERSONAL INJURY, AND/OR DAMAGE TO PROPERTY.

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.

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 wheels must be mounted below
the plane of the guard lip. An improperly mounted wheel that 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. 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. 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.

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 wheels. Do not force a disc onto a
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. damages discs are likely to break apart during this test.
