GENERAL SAFETY RULES
WARNING! Read all instructions.
Failure to follow all instructions listed
below may result in electric shock, fire and/
or serious injury.The term “power tool” in
all of the warnings listed below refers to
your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
SAVE THESE INSTRUCTION
1. Work area
1) Keep work area clean and well lit.
Cluttered or 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.
Distractions can cause you to lose control.
2. Electrical safety
1) 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.
2) 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.
3) Do not expose power tools to rain or
wet conditions. Water entering a power
tool will increase the risk of electric shock.
4) 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.
5) 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.
6) 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
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
serious personal injury.
2) Use safety equipment. Always wear
eye protection. Safety equipment such as
dust mask, non-skid safety shoes, hard hat,
or hearing protection used for appropriate
conditions will reduce personal injuries.
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. Keep your
hair, clothing and gloves away from
moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
7) If devices are provided for the
connection of dust extraction and
collection facilities, ensure these are
connected and properly used. Use
of these devices can reduce dust-related
hazards.
4. Power tool use and care
1) Do not force the power tool. Use
the correct power tool for your
application. The correct power tool will

WX638 WX638.1
WX640 WX640.1
Finishing sander
do the job better and safer at the rate for
which it was designed.
2) 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.
3) 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.
4) 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.
5) 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.
6) Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to bind
and are easier to control.
7) 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.
5. Service
1) Have your power tool serviced by
a qualified repair person using only
identical replacement parts.This will
ensure that the safety of the power tool is
maintained.
ADDITIONAL SAFETY
POINTS FOR YOUR
FINISHING SANDER

3. DUST BOX (See Fig. D, E)
A) ATTACH THE DUST BOX (See Fig. D)
Your sander is equipped with a dust collection box.To
attach, slide the dust box onto the outlet piece and take
care that the dust box locks in the grooves of the outlet.
CAUTION: To prevent the possibility of sanding
dust or foreign body being thrown into your face
or eyes, never attempt to use your sander without the
dust box properly installed.
B) EMPTY DUST BOX (See Fig. E)
For more efficient operation, empty dusts box every
5-10mins.This will permit the air to flow through the
box better.To empty the dust box, pull off the dust box
out of the dust extraction outlet directly and shake out
dust.
4. USING THE DUST EXTRACTION ADAPTER
(See Fig. F, G)
Your sander is equipped with two dust extraction
adapters, which are designed for connecting the hose
of a vacuum cleaner.
If the vacuum hose is 35mm, insert the 35mm dust
adapter (a) directly into the rear dust outlet of sander
(See Fig. F).
If the vacuum hose is 32 mm, insert the 32 mm adapter
(b) into the back of 35mm adapter (a) (See Fig. G).
NOTE: Please pull the dust adapter to make sure
tightened securely on the dust outlet.
5. FLUSH SANDING FACILITY
Your sander can sand flush on three sides of the base
plate which allows easy access to corners and edges of
mouldings.
6. ORBITAL SANDING
Your sander operates in small circular rotations which
allow efficient material removal. Operate your sander
in long sweeping movements across your work piece
and even across the grain. For a finer finish, always use
a fine grain sanding paper and only move the sander in
the direction of the grit and never across the grain. Do

not allow your sander to remain in the same
position otherwise you will remove material
and create an uneven surface.
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.
