Battery installation (VI)
Warning! Before installing the battery in the tool, make sure that the power switch is in the off position, i.e. it is not pressed down.
Slide the battery into the battery socket guides until it latches in the socket. A correctly installed battery cannot be removed other-
wise than by pressing and holding the battery latch in this position, and then pulling the battery out of the tool socket.
Starting the sander
Do not start the sander while leaning the work head against any surface with the sanding sheet being in contact with any object.
This may lead to loss of control of the tool and cause serious injury.
The sander is fi tted with a knob (V) which allows for the adjustment of the motor speed, which translates into disc rotation speed.
The knob is marked with appropriate signs to indicate the direction of the knob rotation for speed control.
Check that the product switch is in the "O" off position (VII).
Move the speed controller to the maximum speed position.
Start the dust extraction system.
Grip the sander with both hands - one hand on the front handle grip and the other on the rear handle grip.
Use your thumb to move the switch to the "I" on position (VIII).
The power switch is equipped with a lock that allows it to retain the "I" on position without the need for continuous hold. This makes
extended work easier. Press the rear part of the power switch and allow it to retract to unlock the switch. If the power switch is not
locked, releasing it will automatically move it to the "O" off position, which will stop the tool operation. The disc may be still spinning
for some time after turning off the sander. Wait until the disc has stopped revolving completely before putting the sander down. It
is forbidden to stop the disc by pressing it against the processed surface.
The disc will start operating at its nominal speed.
Hold the sander in this position and monitor its operation for approx. 1 minute. If you notice any signs of malfunction such as
increased vibration or excessive noise, turn the sander off immediately using the power switch, remove the battery from the tool,
and search for the cause of the malfunction. It is forbidden to resume operation without rectifying the fault.
If there are no signs of malfunction, you can adjust the speed and start working.
Grinder operation
Where required, the processed material must be secured, e.g. with vices or clamps, in such a manner that it cannot move during
work. The sander disc rotates at a high speed and, if not properly secured, the material may move uncontrollably during work,
which would increase the risk of serious injury.
Wear personal protective equipment, such as eye and hearing protection, a dust mask, safety gloves and appropriate work clothing.
Make sure you carry out all assembly and adjustment steps.
Make sure that the power switch is in the "off " position, then connect the battery to the tool socket.
Always hold the sander with both hands gripping its front and rear handles. If the extension arm is used, grip the rear handle and
the extension arm handle.
Allow the sander to reach full speed and only then start working the material.
After fi nishing work, use the power switch to turn off the sander, remove the battery from the tool, and proceed with maintenance.
Grinder operation tips
It is forbidden to hold the sander in any other way but by the handle grips. Do not hold the sander by any parts of the housing
other than the handle grips.
Always hold the sander with both hands.
Do not press the sander against the processed surface too hard. Excessive pressure can cause the sander to overheat and
damage the processed surface.
Position the sander so that the entire surface of the sanding sheet is used. This will ensure uniform wear of the sheet.
Move the sander towards and away from you, and gradually to a side. Do not move the sander in circles. Wood should be sanded
along the grain. Sanding should be started with coarse-grit sandpaper, then use increasingly fi ner-grit sandpapers until the desired
eff ect is achieved. Avoid checking the condition of the processed wood surface with your bare hand. This can cause injury from
splinters and burrs generated during work.
The sander features two areas from which dust is transported to the dust extraction system. One area is the holes in the lower side
of the work head, and the other one is a gap between the edge of the work head and the guard. The dust extraction force must be
selected experimentally during operation. The greatest force will not always be the most eff ective. The airfl ow generated during
operation may cause the sander to suck too much to the ground surface, which will make it diffi cult for dust to move towards the
holes in the disc or its edges, and reduce the performance. If the extraction force is too low, the dust generated during operation
will remain on the material.
The tool speed and sandpaper sheet grades must be selected according to the processed surface. Too high grit size of the sand-
paper will produce scratches on the processed material surface.
Higher speeds should be used for sanding ceramic materials and non-resinous wood. Resin wood should be sanded at a lower
speed. If the speed is too high, the resin in the wood will heat up quickly and the sanding sheet will become clogged. For a similar
reason, sanding paints and varnishes should also be carried out at a lower speed.
