ORIGINAL INSTRUCTIONS
GENERAL POWER TOOL
SAFETY WARNINGS
WARNING: Read all safety warnings
and all instructions. Failure to follow the
warnings and instructions may result in electric
shock, fire and/or serious injury.
Save all warnings and instructions for future
reference.
The term “power tool” 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 dust mask, non-skid safety shoes, hard
hat, or hearing protection used 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, clothing and
gloves away from moving parts. Loose
clothes, jewellery or long hair can be caught in
moving parts.
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.
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 the battery pack 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. 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 HINTS FOR YOUR
FINISHING SANDER
If your power tool becomes too hot, especially when
used at low speed, set the speed to maximum and run
it with no load for 2-3 minutes to cool the motor. Avoid
prolonged usage at very low speeds. Always use sand
paper that is suitable for the material you want to sand.
Always ensure the work-piece is firmly held or
clamped to prevent movement.
Any movement of the material may affect the quality
of the sanding finish.
Start your sander before sanding and turn it off only
after you stop sanding. For the best results, sand
wood in the direction of the grain.
Do not start sanding without having the sandpaper
fitted.
Do not allow the sandpaper to wear away it will
damage the base-plate.The guarantee does not cover
base-plate wear and tear.
Use coarse grit paper to sand rough surfaces,
medium grit for smooth surfaces and fine grit for the
final surfaces. If necessary, first make a test run on
scrap material.
Use only good quality sandpaper.
The sandpaper controls the sanding efficiency, not
the amount of force you apply to the tool. Excessive
force will reduce the sanding efficiency and cause
motor overload. Replacing the sandpaper regularly
will maintain optimum sanding efficiency.
MAINTENANCE
Remove the plug from the socket before
carrying out any adjustment, servicing or
maintenance.
Your power tool requires no additional lubrication
or maintenance.There are no user serviceable parts
in your power tool. Never use water or chemical
cleaners to clean your power tool. Wipe clean with
a dry cloth. Always store your power tool in a dry
place. Keep the motor ventilation slots clean. Keep
all working controls free of dust. Occasionally you
may see sparks through the ventilation slots.This
is normal. If the supply cord is damaged, it must be
replaced by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard.
