• Use safety goggles or glasses when operating the sander above
head.
• When operating the sander do not apply excessive pressure that
might stop the tool.
CAUTION! This device is designed to operate indoors.
The design is assumed to be safe, protection measures and
additional safety systems are used, nevertheless there is always a
small risk of operational injuries.

CONSTRUCTION AND USE
Orbital sanders are hand-operated power tools with insulation class II.
Tools are driven by single-phase commutator motors. Orbital sander is
designed for sanding and polishing surfaces of wood, metal, plastic and
similar materials, with the use of sanding paper with appropriate gradation.
Range of use covers repair and building works, and any work from the
range of individual, amateur activities (tinkering).
Do not use the sander for sanding surfaces that contain magnesium or
asbestos, or covered with gypsum.
OPERATION
Choosing sanding paper
Coarse-grained sanding paper is used for coarse processing of most
materials, while fine-grained paper is used for finishing works.
• When the surface is not flat, start the work with coarse-grained
sanding paper and continue until the surface is flat.
• Next use middle-grained paper to remove traces of coarse
processing.
• To finish the work use fine-grained sanding paper.
Installing sanding paper
Orbital sander is equipped with pad with so called hook-and-loop and only
perforated sanding paper of appropriate size should be used.
• Put the sanding paper close to the sander backing pad.
• Place the paper so it's holes match holes on the sander backing pad
(fig. B)
• Press the sanding paper against the backing pad.
• Ensure that the holes on the sanding paper and backing pad fully
match; it ensures possibility of dust extraction.
Switching on / switching off
• Turning On - Move the switch on the front of the body to the right to
the on position.
• Shutdown - Slide the switch on the front of the body to the left to the
off position.
Speed setting
The sander is equipped with a knob to set the gear and increase the
rotational speed of the disc (fig. C). The speed must be set before turning
on the sander.
Orbital sander operation
• Whole area of backing pad must rest on the processed surface.
• Turn the sander on and apply moderate pressure; move it on the
processed material in circular movements, in transverse or
lengthwise direction.
• For coarse processing use sanding paper with coarse grain, for
finishing processing use fine-grained paper. It is best to match the
type of sanding paper by trials and errors.

• When finishing polishing, reduce pressure, lift the sander above the
processed surface and only after that switch the tool off.
Dust extraction system
The sander is equipped with a built-in dust extraction system located at
the rear of the device. It has been designed to work with a box put directly
on the exhaust or with a vacuum cleaner. The box should be emptied
regularly.
STORING AND MAINTENANCE
Unplug the power cord from the mains socket before commencing any
activities related to installation, adjustment, repair or maintenance.
• Always keep the sander clean.
• Remember to always keep the ventilation holes of the sander casing
pervious.

• Never use any caustic agents for cleaning plastic parts.
• In case of excessive commutator sparking check technical condition
of carbon brushes of the motor.
Replacement of backing pad
Damaged backing pad must be replaced immediately
• Unscrew four screws that fix the backing pad.
• Remove and replace the backing pad.
• Screw the fixing screws.
Replacement of carbon brushes
Replace immediately used up (shorter than 5 mm), burnt or cracked motor
carbon brushes. Always replace both brushes at a time.
Entrust replacement of carbon brushes only to a qualified person. Only
original parts should be used.
All faults should be repaired by service workshop authorized by the
manufacturer.

devices and for a preliminary assessment of vibration exposure.
The stated vibration level is representative only for the basic use of the
device. If the machine is used for different applications or with different
working tools, the vibration level may change. The higher level of
vibrations will be influenced by insufficient or too rare maintenance of the
device. The reasons given above may result in an increased exposure to
vibration during the entire period of operation.
To accurately estimate exposure to vibration, consider periods when
the equipment is turned off or when it is turned on but not in
use. After all factors have been carefully assessed, the overall
vibration exposure may be significantly lower.
In order to protect the user against the effects of vibrations, additional
safety measures should be implemented, such as: periodic maintenance
of the device and working tools, protection of the appropriate temperature
of hands and proper organization of work.
