5. HEALTH AND SAFETY INFORMATION
5.1 GENERAL SAFETY INSTRUCTIONS FOR POWER TOOL USE
Warning! Read all safety warnings, instructions, illustrations and specifications provided
with this power tool. Failure to follow all instructions listed below may result in electric shock, fire
and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tools” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not
use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current
device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3) Personal safety
a) 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 serious personal injury.
b) Use personal protective equipment Always wear eye protection. Protective equipment
such as a dust mask, non-skid safety shoes, hard hat or hearing protection use for
appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before
connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energising power tools that have the
switch on invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing
away from moving parts. Loose clothes, jewellery or long hair can be caught in moving
parts.
– 6 –
5. HEALTH AND SAFETY INFORMATION
g) If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of dust collection can reduce
dust-related hazards.
h) Do not let familiarity gained from frequent use of tools allow you to become
complacent and ignore tool safety principles. A careless action can cause severe injury
within a fraction of a second.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application. The correct
power tool will do the job better and safer at the rate for which it was designed.
b) 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.
c) Disconnect the plug from the power source and/or remove the battery pack, if
detachable, from the power tool before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar
with the power tool or these instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
e) Maintain power tools and accessories. 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.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to be performed.
Use of the power tool for operations different from those intended could result in a hazardous
situation.
h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for safe handling and control of the tool in
unexpected situations.
5) Service
a) Have your power tool serviced by a qualified repair person using only identical
replacements parts. This will ensure that the safety of the power tool is maintained.

10. MAINTENANCE
10.1 REPLACING THE GRINDING
WHEEL – FIG.16
Warning! For your own safety, always turn the
main switch on the machine OFF and remove the
plug from the power supply before carrying out any
servicing or maintenance.
− Remove the 3 screws from the grinding wheel
cover (FIG.16).
− Using an appropriate sized Hex. key (not
supplied), insert it into the aperture located on
the side of the drive shaft housing (FIG.17)
− Lock the drive shaft.
− Using a 17mm spanner (not supplied), undo the
grinding wheel retaining nut (18).
Note: Take care to note which washers and
spacers are mounted on each particular grinding
wheel. The diamond coated disc uses the thick,
black spacers, whilst the ceramic disc uses the
zinc-coated washers on each side.
Note: When fitting the ceramic disc, refer to
FIGS.4 – 5 on page 14, to make sure the disc is
fitted the correct way round.
10.2 MAINTENANCE
Regular inspection and cleaning reduces the
necessity for maintenance operations and will keep
your tool in good working condition.
The motor must be correctly ventilated during tool
operation. Avoid blocking the air inlets and vacuum
the ventilation slots regularly.
