DUST EXTRACTION
Finishing sander features a dust bag for collecting dust, to maintain the processed surface clean.
Slide the dust bag mounting (3) onto the dust discharge outlet (2) and secure by turning it right (fig. C).
Check whether the dust bag is firmly fixed on the dust discharge outlet by pulling it gently (the dust bag
is sealed with a rubber O-ring seal).
The dust bag is placed in plastic dust bag housing (3). To empty the dust bag, slide back rear part of the
plastic housing (fig. D), remove the dust bag from its mounting and remove its content. Assemble the dust
bag in reverse order to its disassembly.
SWITCHING ON / SWITCHING OFF
The mains voltage must match the voltage on the rating plate of the sander.
Switching on – turn the switch button (1) to position I (fig. E)
Switching off – turn the switch button (1) to position 0.
USING THE FINISHING SANDER
The whole sanding area of the sander backing pad must rest on the processed surface.
Apply moderate pressure on the sander, move it on the processed material using rotary movements in
transverse or longitudinal direction.
Use coarse-grained abrasive paper for coarse processing and fine-grained abrasive paper for finishing
works. Best method of selection of abrasive paper is by trial and error.
When finishing polishing, reduce pressure and lift the sander above the processed surface and only then
switch the sander off.
Prior to commencing any installation, regulation, repair or maintenance work always unplug the
power cord of the sander from power supply socket.
MAINTENANCE AND STORAGE
It is recommended to clean the sander immediately after each use.
Do not clean the device with water or other liquids.
The device should be cleaned with a paintbrush or with compressed air at low pressure. Do not use any
cleaning agents or solvents, as they may damage the parts made of plastic.
Clean ventilation slots in the motor housing on regular basis to prevent overheating of the device.
In case of excessive commutator sparking have the technical condition of carbon brushes of the motor
checked.
The device must always be stored in a dry place out of reach of children.
REPLACEMENT / CHANGE OF SANDER BACKING PAD
Depending on the need and the type of work performed an appropriate backing must be used. Types of
backing pads provided together with the sander are shown in figure F.
Remove screws securing the backing pad (4) (figure G).
Remove and replace the backing pad.
Tighten the screws.
Damaged sander backing pad must be replaced immediately.
REPLACING CARBON BRUSHES

Always replace both brushes at a time.
Replacement of carbon brushes may only be done by a qualified person and with use of genuine
parts.
