General Power Tool Safety Warnings
SAFETY INFORMATION
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 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 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

EN-3
Important - Please read these instructions fully before starting assembly
General Power Tool Safety Warnings
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 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.

EN-4
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 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.

EN-5
ADDITIONAL SAFETY RULES
1) Always wear eye protection.
2) Always wear ear protection during extended
periods of operation..
3) Always inspect and remove all nails and screws etc
before sanding.
4) Always check walls and ceilings to avoid hidden
power cables and pipes. A metal detector can be
obtained from any good DIY store for this purpose.
5) Use the original accessories and the tool provided,
no others.
6) Only use accessories in good condition. Do not use
torn or worn accessories.
7) Do not turn the machine on whilst any of the
accessories are resting on or inserted into the
work piece or material that you want to work with.

Vibration Information
Vibration total values (triax vector sum) determined according to EN 60745:
Vibration emission value:
ah = 4.943m/s2 Uncertainty K = 1,5 m/s²
The declared vibration total value may be used for comparing one tool with another, and 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 if any anti vibration accessories are used.
And the tool is being used as intended by its design and these instructions.
This tool may cause hand-arm vibration syndrome if its use is not adequately
managed.
WARNING! To be accurate, an estimation of exposure level in the actual conditions of use
should also take account of all parts of the operating cycle such as the times when the tool is
switched off and when it is running idle but not actually doing the job. This may signicantly reduce the
exposure level over the total working period.
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)
If the tool is to be used regularly then invest in anti vibration accessories.
Plan your work schedule to spread any high vibration tool use across a number of days.

OPERATING INSTRUCTIONS
NOTE: Before using the tool, read the instruction book carefully.
Intended Use
The machine is intended for dry sanding of wood, plastic, metal and ller material as well as painted
surfaces. Machines with electronic control are also suitable for polishing.
1. FITTING THE SANDING PAPER (SEE FIG A, B)
FIT THE SANDING PAPER
This sander features an easy hook and loop accessory fastening system for quick changing without
clamps.
The sanding papers are placed directly onto the base plate. The hole pattern in the base plate and
sanding paper must match. Then press the sanding paper onto the base plate by hand. Firmly press
the power tool with the sanding paper against a at surface and briey switch the power tool on. This
provides for good adhesion and prevents premature wear
Before placing on the sanding paper, free the base plate from dust/debris by lightly
tapping against it.
REMOVE THE SANDING PAPER
Simply remove the sanding paper directly.
2. INSTALLING THE AUXILIARY HANDLE (SEE FIG. C)
For your personal safety we recommend using the auxiliary handle at all times.
To adjust the handle, release the auxiliary handle locking knob and rotate the handle , the tool has
preset some locked positions, choose the most comfortable and balanced one. Then press the auxiliary
handle locking knob.
3. DUST COLLECTION/EXTRACTION (SEE FIG. D1,D2,D3,D4,D5,D6)
– Dust produced while working can be detrimental to health, inammable or explosive. Suitable
protection measures are required. Examples: Some dusts are considered to be carcinogenic. Use
suitable dust/chip extraction and wear a dust protection mask.
– Light metal dust can burn or explode. Always keep the work place clean since material mixtures are
especially dangerous.
CAUTION: Fire hazard! For unfavorable conditions such as ying sparks when sanding metals,
sanding dust in the dust bag, micro lter or paper sack (or in the lter sack or lter of the wet/
dry vacuum cleaner) can self-ignite, especially when mixed with remainders of varnish, polyurethane
or other chemical materials and when the sanded work piece is hot after long periods of working. Avoid
overheating the object being sanded as well as the machine and always empty the dust container
before pauses in the work.
A) Internal vacuuming with dust bag
Attaching The Dust Bag
Push the dust bag into the adapter.(SEE FIG. D1), and rotate the dust bag clockwise.(SEE FIG. D2).
Place the dust bag with adapter on the outlet piece and allow the latching lever to latch. (SEE FIG. D3)
Empty The Dust Bag
Always operate your sander with the dust bag with adapter tted. To remove the dust bag with adapter,
take the dust bag with adapter away from the sander. (SEE FIG. D4) . Then rotate the dust bag
counterclockwise and pull off the dust box out of adapter directly and shake out dust.(SEE FIG. D5,D6)
. For the best performance, always empty the dust bag in time. To ret the dust bag with adapter, rmly

EN-13
push the dust bag with adapter into the location on the sander housing.
4. OPERATING THE ON/OFF SWITCH (SEE FIG E, F)
Slide the on/off switch to the position marked ”I” to start the tool. (SEE FIG E)
Slide it to the position marked “0” to stop it. (SEE FIG F)
5. VARIABLE SPEED CONTROL (SEE FIG G)
With the variable speed control (1), the required speed can be selected (also while running).
The required speed is dependent on the material and is to be determined by a practical trial.
After longer periods of working at low speed, allow the tool to cool down by running it for approx. 3
minutes at maximum speed with no load.
6. USING THE SANDER (SEE FIG. H)
Guide your sander parallel to the working surface and move it in circles or in a cross pattern. Do not tilt
the tool in order to avoid deep unwanted sanding marks. The amount of material removed is determined
by the speed of the sanding disc and the grit size used. The speed of the sanding disc diminishes
relative to the pressure applied to the tool. For faster removal, do not increase pressure on the tool, but
use a coarser grit size .
7. SELECT THE RIGHT SAND PAPER
Selecting the correct grit of sanding paper is an extremely important decision that will allow you to achieve
the best quality sanding nish.
Coarse grit will remove the most material and ner grit will give you the best nish in all sanding operations.
The condition of the surface to be sanded will determine which grit will do the job.
If the surface is rough:
Start with coarse grit (sold separately) and sand until the surface is uniform. Then use medium to
remove any scratches left by the coarse grit. Then use ner grit (sold separately) for nishing the
surface.
NOTE: Always continue sanding with each grit until the surface is uniform.
WORKING HINTS FOR YOUR 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, sanding
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 efciency and cause motor overload. Replacing the sandpaper regularly
will maintain optimum sanding efciency.

EN-14
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
qualied persons in order to avoid a hazard.
TROUBLESHOOTING
1. If your sander will not operate, check the power at the mains plug.
2. If the sander does not abrade surface, checking the sanding paper. If the sanding paper has 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 cannot be rectied return the sander to an authorized dealer for repair.
