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, re and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your electric (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 ammable 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. Unmodied 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,

240W 1/4 SHEET SANDER
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 inuence 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 nger 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.

240W 1/4 SHEET SANDER
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 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
a. Have your power tool serviced by a qualied repair person
using only identical replacement parts. This will ensure that
the safety of the power tool is maintained.
b. If the replacement of the supply cord is necessary, this
has to be done by the manufacturer or his agent in order to
avoid a safety hazard.
ADDITIONAL SAFETY INSTRUCTIONS FOR YOUR SANDER
1. Harmful/toxic dusts will arise from sanding e.g. lead painted
surfaces, woods and metals. Contact with or inhalation of these

240W 1/4 SHEET SANDER
dusts can endanger the health of operator and bystanders.
Always use eye glasses and dust mask.
2. Hearing protection should be worn when using the sander.
3. Always wear safety glasses or eye shields when using the
sander. Everyday eyeglasses have only impact-resistant

240W 1/4 SHEET SANDER
Warning: Some dust particles created by power sanding, sawing, grinding, drill
and other construction jobs contain chemicals known to cause cancer, birth
defects or other reproductive harm. Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks and cement and other masonry products.
• Arsenic and chromium from chemically treated timber.
Your risk from these exposures varies, depending upon how often you do this type of work.
To reduce your exposure to these chemicals:
• Work in a well-ventilated area.
• Work with approved safety equipment, such as those dust masks that are specially
designed to lter microscopic particles.
VIBRATION
The European Physical Agents (Vibration) Directive has been brought in to help reduce
hand arm vibration syndrome injuries to power tool users. The directive requires power
tool manufacturers and suppliers to provide indicative vibration test results to enable users
to make informed decisions as to the period of time a power tool can be used safely on a
daily basis and the choice of tool.
Further Advice can be found at www.hse.gov.uk
Vibration total values (triax vector sum) determined according to EN 60745:
Typical weighted vibration Vibration emission value ah = 4.86 m/s²
Uncertainty K = 1.5 m/s²
The declared vibration emission value should be used as a minimum level and should be
used with the current guidance on vibration.
Calculating the actual period of the actual period off use can be difcult and the HSE
website has further information.
The declared vibration emission been measured in accordance with a standardised test
stated above and may be used to compare one tool with another tool.
The declared vibration emission value may also be used in a preliminary assessment of
exposure.
Warning: The vibration emission value during actual use of the power tool can differ
from the declared value depending on the ways in which the tool is used dependant
on the following examples and other variations on how the tool is used:
How the tool is used and the materials being cut or drilled.
The tool being in good condition and well maintained
The use the correct accessory for the tool and ensuring it is sharp and in good condition.
The tightness of the grip on the handles.
And the tool is being used as intended by its design and these instructions.
While working with this power tool, hand/arm vibrations occur. Adopt the correct
working practices in order to reduce the exposure to vibration.

240W 1/4 SHEET SANDER
This tool may cause hand-arm vibration syndrome if its use is not adequately
managed.
Warning: identify safety measures to protect the operator that are based on an
estimation of exposure in the actual conditions of use (taking account of all parts of
the operating cycle such as the times when the tool is switched off and when it is running
idle in addition to the trigger time).Note The use of other tools will reduce the users’ total
working period on this tool.
Helping to minimise your vibration exposure risk.
ALWAYS use sharp chisels, drills and blades
Maintain this tool in accordance with these instructions and keep well lubricated
(where appropriate)
Avoid using tools in temperatures of 10ºC or less
Plan your work schedule to spread any high vibration tool use across a number of days.
Health Surveillance
All employees should be part of an employer’s health surveillance scheme to help identity
any vibration related diseases at an early stage, prevent disease progression and help
employees stay in work.
Double insulation
The tool is double insulated. This means that all the external metal parts are
electrically insulated from the mains power supply. This is done by placing insulation
barriers between the electrical and mechanical components making it unnecessary for the
tool to be earthed.
Important note
Be sure the supply is the same as the voltage given on the rating plate. The tool is tted
with a two-core cable and plug.
Remove the mains plug from socket before carrying out, any adjustment or servicing.

OPERATING INSTRUCTIONS
Note: Before using the tool, read the
instruction book carefully.
1.CHANGING THE SANDING PAPER (See Fig.
1-1, 1-2)
To remove the sanding paper, lift up the clamp lever
(8) and move away from the clamp lever lock (6).
The sanding paper clamp (7) is now loose. Repeat
with the other clamp on the opposite side of your
sander.
To t new sanding paper, insert approximately 5mm
of one end of the sanding paper under the sanding
paper clamp (7) until the paper contacts the housing
wall. Lift up the clamp lever (8) and move it to the
lever lock position. Press the sanding paper around
the base plate shape as tight as possible and x the
end under the other sanding paper clamp (7).
Check the sanding paper is square to the base
plate. If not correct, remove and ret it again.
Always, ensure the sanding paper is tight over the
base plate and secured underneath both locked
clamps(7). This will ensure safe and efcient
sanding performance.
For hoop & loop sanding paper, align the sanding
sheet and press it onto the sanding pad by hand.
Firmly press the power tool with the sanding sheet
against a at surface and briey switch the power
tool on. This provides for good adhesion and
prevents premature wear.
2. PAPER PUNCH
If using sanding paper without dust holes, use the
paper punch (9) to perforate the holes to ensure
correct dust extraction. Position the punch over the
base-plate (5) with the punch sides on the edges of
the base-plate.
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.
3. USING THE DUST BAG (See Fig. 2)
Your sander is equipped with a dust collection bag.
To attach, insert the dust collection bag into the
back of the sander until it is secure.
Caution:To prevent the possibility of sanding
dust or foreign body being thrown into your
face or eyes, never attempt to use your sander

Fig. 1-2
Fig. 2
Fig. 3-1

240W 1/4 SHEET SANDER
without the dust box/bag properly installed.
Empty dust bag (See Fig. 3-1, 3-2)
For more efcient operation, empty dust bag every
5-10mins. This will permit the air to ow through the
bag better. To empty the dust bag, remove it from
the dust extraction port, shake out dust.
Using the dust extraction adaptor (See Fig. 3-3)
Your sander is equipped with a dust extraction
adaptor, which is designed for collecting dust task.
Connect the dust extraction adaptor into the hose of
a vacuum cleaner.
First please turn on the vacuum cleaner, then turn
on the sander. If you stop sanding, rst turn off the
sander, then turn off your vacuum cleaner.
4. OPERATING THE SWITCH (See Fig. 4)
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”.
5. FLUSH SANDING FACILITY
Your sander can sand ush on three sides of the
baseplate which allows easy access to corners and
edges of mouldings.
6. ORBITAL SANDING
Your sander operates in small circular rotations
which allows efcient material removal. Operate
your sander in long sweeping movements across
your workpiece and even across the grain. For a
ner nish, always use a ne 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 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
rmly held or clamped to prevent movement. Any
movement of the material may affect the quality of

the sanding nish. 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
tted. 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 ne grit for the nal surfaces.
If necessary, rst make a test run on scrap material.
Use only good quality sandpaper. The sandpaper
controls the sanding efciency, not the amount of
force you apply to the tool. Excessive force will
reduce the sanding fciency and cause motor
overload. Replacing the sandpaper regularly will
maintain optimum sanding efciency.
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 and will not damage your power tool. If the
supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualied
persons in order to avoid a hazard.

240W 1/4 SHEET SANDER
TROUBLESHOOTING
1. If your sander will not operate, check the power
at the mains plug.
2. If the sander does not abrade surface, check the
sanding paper. If the sanding paper have been
worn, replace the new paper and try again. The
paper must be kept in a dry place; If it is allowed
to become damp, the abrasive particles will lose
their adhesion to the backing paper and will not
abrade.
3. If the sander dose not move smoothly, The
sanding paper may be loose, damaged or
wrinkled. Replace and try again.
4. If a fault can not be rectied return the sander to
an authorized dealer for repair.
