SAFETY INSTRUCTIONS

WARNING! Read and understand all instructions. Failure to follow all instructions listed
below, may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

1. WORK AREA
a) Keep your work area clean and well lit. Cluttered benches and 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 bystanders, children, and visitors away while operating a power tool. Distractions

can cause you to lose control.

2. ELECTRICAL SAFETY
a) Double Insulated tools are equipped with a polarized plug (one blade is wider than the

other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in
the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install
a polarized outlet. Do not change the plug in any way. Double Insulation eliminates the

need for the three wire grounded power cord and grounded power supply system.

b) Avoid body contact with grounded surfaces such as pipes, radiators, ranges and

refrigerators. There is an increased risk of electric shock if your body is grounded.

c) Don’t 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 to carry the tools or pull the plug from an

outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged
cords immediately. Damaged cords increase the risk of electric shock.

e) When operating a power tool outside, use an outdoor extension cord marked “W-A” or

“W”. These cords are rated for outdoor use and reduce 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 tool while 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) Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair,

clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be

caught in moving parts.

c) Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with

your finger on the switch or plugging in tools that have the switch on invites accidents.

d) Remove adjusting keys or wrench before turning the tool on. A wrench or a key that is left

attached to a rotating part of the tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance at all times. Proper footing and

balance enables better control of the tool in unexpected situations.

f) Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes,

hard hat, or hearing protection must be used for appropriate conditions.

4. TOOL USE AND CARE
a) Use clamps or other practical way to secure and support the workpiece to a

stable platform. Holding the work by hand or against your body is unstable and may lead

to loss of control.

Palm Sander WT645K

b) Do not force tool. Use the correct tool for your application. The correct tool will do

the job better and safer at the rate for which it is designed.

c) Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled

with the switch is dangerous and must be repaired.

d) Disconnect the plug from the power source before making any adjustments,

changing accessories, or storing the tool. Such preventive safety measures reduce the

risk of starting the tool accidentally.

e) Store idle tools out of reach of children and other untrained persons. Tools are

dangerous in the hands of untrained users.

f) Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained

tools, with sharp cutting edges are less likely to bind and are easier to control.

g) Check for misalignment or binding of moving parts, breakage of parts, and any

other condition that may affect the tools operation. If damaged, have the tool
serviced before using. Many accidents are caused by poorly maintained tools.

h) Use only accessories that are recommended by the manufacturer for your model.

Accessories that may be suitable for one tool, may become hazardous when used on another
tool.

5. SERVICE
a) Tool service must be performed only by qualified repair personnel. Service or

maintenance performed by unqualified personnel could result in a risk of injury.

b) When servicing a tool, use only identical replacement parts. Follow instructions

in the Maintenance section of this manual. Use of unauthorized parts or failure to follow

Maintenance Instructions may create a risk of electric shock or injury

6. SPECIFIC SAFETY RULES
a) Hold tool by insulated gripping surfaces when performing an operating where the

cutting tools may contact hidden wiring or its own cord. Contact with a “live” wire

will make exposed metal parts of the tool “live” and shock the operator.

ADDITIONAL SPECIFIC SAFETY INSTRUCTIONS FOR BELT
SANDER

1. Remove the plug from the socket before carrying out any adjustment, servicing or

maintenance.

2. Fully unwind cable drum extensions to avoid potential overheating.

3. When an extension cable is required you must ensure it has the correct ampere rating for your

OPERATING INSTRUCTIONS

1. ON /OFF SWITCH

To start your sander, depress the protective cover over
the switch at the position marked“I”.To stop your sander,
depress the protective cover at the position marked “0”.

2. HAND GRIP AREA

You can operate your sander with one hand (See Fig 1).

3. CHANGING THE SANDING PAPER

To remove the sandpaper, lift up the clamp lever (4)
and move away from the lever lock (5) (See Fig 2). The
sandpaper clamp (3) is now loose. Repeat with the other
clamp on the opposite side of your sander.
To fit new sandpaper, insert approximately 5mm of one
end of the sandpaper under the sandpaper clamp (3) until
the paper contacts the housing wall (See Fig 2). Lift up the
clamp lever (4) and move it to the lever lock position.
Press the sandpaper around the base-plate shape as tight
as possible and fix the end under the other sandpaper
clamp (3). Check the sandpaper is square to the base­plate, If not correct., remove and refit it again .
Always, ensure the sandpaper is tight over the base-plate
and secured underneath both locked clamps (3). This will
ensure safe and efficient sanding performance.

4. PAPER PUNCH

If using sanding paper without dust holes, use the paper
punch (7) to perforate the holes to ensure correct dust
extraction. Position the punch over the base-plate (8) with
the punch sides on the edges of the base-plate (See Fig 3).
Press the punch into the base-plate to punch holes into the
sanding paper. Then remove the punch and check all the
holes have been formed correctly.

5. DUST BAG

Always operate your sander with the dust bag fitted. For
the best performance always empty the dust bag in time.
Open the zip and empty the dust from the bag. To remove
the bag (See Fig 4). To refit the bag, firmly push the
mounting bracket into the location on the sander housing
(See Fig 5).

6. FLUSH SANDING FACILITY

Your sander can sand flush on three sides of the base­plate which allows easy access to corners and edges of
moulding (See Fig 6).

7. ORBITAL SANDING

Your sander operates in a small circular rotation which

allows efficient material removal.
Operate your sander in long sweeping movements across
your workpiece and even across the grain. For a finer
finish, always use a fine type sand paper and only move
the sander in the direction of the grain 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.

WORK HINTS FOR YOUR PALM
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.

MAINTAIN TOOLS WITH CARE

Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and
changing accessories. Inspect tool cords periodically and
if damaged, have repaired by authorized service facility.
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. If you see some sparks flashing in the
ventilation slots, this is normal and will not damage your
power tool.
