surface is flat.
Next use middle-grained paper to remove traces of coarse processing.
To finish the work use fine-grained sanding paper.
3.2. Installing sanding paper.
Orbital sander is equipped with pad with so called VELCRO (hook-and-loop) and only perforated
sanding paper of appropriate diameter size 125 mm should be used.
3.3. Put the sanding paper close to the sander backing pad.
Place the paper so its holes match holes on the sander backing pad.
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.
3.4. Dust extraction.
Equipment of orbital sander includes dust container that helps to maintain the processed surface
clean.
When the container is full, remove and empty it by opening its lower lid.
Use water with soap to wash the filter. Dry thoroughly. Do not use cleaning agents or detergents.
Assemble the dust container and reinstall it on the dust outlet.
Ensure the dust container is well fixed on the dust outlet by pulling it gently.
It is recommended to empty the container when it is half-full.
4. Operation and settings.
4.1. Switching On / Switching Off.
Press the switch button (1) and fix in ON position.
Switching off: Press and release the switch button (1).
4.2. Wheel for spindle rotational speed control.
Orbital sander allows for operation with different spindle speeds. It can be controlled with the wheel
for speed control (3). Speed adjustment is 6 stages.
Choose proper rotational speed when the orbital sander operates with no load, and with switch lock
button pressed. Defined speed may decrease under load.
4.3. 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.
5. Operation and 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.
5.1. 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.
5.2. Any faults should be repaired by service workshop authorized by RAIDER.
6. Environmental protection.
In order to protect the environment, the power tool, accessories and packaging must be suitably
processed for the reuse of the raw materials contained therein.
Do not dispose of power tools in household waste! According to the European Union Directive
