Use perforated abrasive paper so that the dust can reach the dust
extraction system through the holes in the working disc. Before
changing the abrasive paper each time, clean the work disc by
removing dust and any debris from the disc with a brush or
brush, for example.
DUST EXTRACTION
• Push the end of the suction hose onto the dust extraction nozzle fig. C3
or fig. C6 if using the extension.
• Connect the other end of the supplied suction hose to a suction system
such as a workshop hoover.
LIFT FORCE ADJUSTMENT
The suction force is adjusted by turning the knob to the left or right,
fig. E1.
OPERATION / SETTINGS
The mains voltage must correspond to the voltage specified on
the grinder's rating plate.
• Switching on - press the switch button fig. A5. Switching off - release
pressure on the switch button fig. A5.
Switch lock (continuous operation)
Switching on:
• Press the on/off button Fig. A5 and hold it in this position.
• Press the on/off button Fig. A5 to lock for continuous operation.
• Release pressure on the switch button Fig. A5.
Switching off:
• Press and release the pressure on the switch button Fig. A5.
SPEED CONTROL
There is a speed adjustment knob on the body of the sander Fig. A6. The
speed is selected as required (depending on the abrasive paper used, the
hardness of the material being worked on, the type of work, etc.). Turning the
speed adjustment knob fig. A6 increases or decreases the speed of the
working disc .
GRINDING WORK
The surfaces to be machined should be dry and free of foreign
matter such as screws, nails, bolts, etc.
Hold the sander securely with both hands.
• Switch on the grinder and wait for the working disc to reach
maximum speed.
• Apply the entire surface of the work disc to the work surface (the
movable work disc guard automatically adjusts to the surface).
• Exerting moderate pressure, move the sander across the work
surface in circular or alternating transverse and longitudinal
movements.
• Excessive pressure does not lead to an increase in sanding
performance, but can cause faster wear of the sanding machine
components and sandpaper.
• If the working disc is moved away from the sanding surface during
operation, dust will escape to the outside of the machine and thus
into the working room.
• The performance and quality of the sanded surface largely depends on the
type of abrasive paper used and the contact pressure. The type of
sanding paper is best selected by trial.
• When finishing sanding, reduce pressure on the sander, switch off the
motor.
• Replace the sandpaper when wear is observed.
• Use periodic breaks.
Do not start the grinder if its work disc is resting against the
work surface.
SANDING IN THE CORNERS
The sander is equipped with an additional triangular-shaped sanding
disc, which is used precisely for sanding in corners Figure B6.
REPLACEMENT OF GRINDING DISC
To change the disc, unlock the disc retaining clamps fig. B3 located on
the motor and remove the mounted grinding disc pad fig. A4 or fig.
A16. To correctly install the second disc, the following components of
the grinder and disc must be fitted together:
• Dust extraction nozzle fig. B2 located on the disc with the flexible
dust extraction nozzle fig. B1 located on the motor housing.
• Disc rotation and oscillation drive coupling Fig. B4 with matching
input on the disc on the motor housing.
• The locating hole of the disc Figure B7 with the matching pin on the
disc on the motor housing.
• The final step is to lock the disc mounting clamps Fig. B3.
SANDING AGAINST THE WALL
The grinder is equipped with the possibility to remove the dust cover
part of the round disc fig. E3. To remove the guard, unhook the guard
part clip fig. E2. Working without the guard part allows a very close
approach to the edge of the wall or ceiling.
ATTENTION: Remember to put the cover back in place when you have
finished work. Not doing so will result in a significant increase in dust in
the room
TORCH
The sander is equipped with a torch fig. A7 to make it easier to find
irregularities on the wall to be sanded. When the torch Fig. A7 is
switched on and illuminates the working area, any unevenness on the
wall that needs to be corrected becomes visible. The torch is switched
on by pressing the button fig. D1 and switched off fig. D1.
OPERATION AND MAINTENANCE
Disconnect the unit from the mains supply before carrying out
any adjustment, maintenance or repair work.
• Keep the grinder clean at all times.
• Do not use water or other liquids for cleaning.
• The sander should be cleaned with a brush.
• Clean the ventilation slots regularly to prevent the grinder motor from
overheating.
• The motor protection filter fig. A12 must be cleaned regularly. To clean
it, remove the filter block fig. D3 take out the filter fig. D4 clean it of dust.
It can be washed but must dry naturally before it is put back in place.
Place the clean and dry filter again fig. D4 lock it again fig. D3.
• If there is excessive sparking on the commutator, check the condition
of the motor's carbon brushes.
• Always store the grinder in a dry place out of the reach of children.
REPLACEMENT OF SANDING PAD
• If the sanding pad is damaged, it is available as a spare part.
• After removing the sandpaper, use a spanner inserted into the holes
in the sanding pad with Velcro and loosen the screws. Then remove
the old sanding pad, install the new pad and tighten the screws.
REPLACEMENT OF CARBON BRUSHES
Worn (shorter than 5 mm), burnt or cracked motor carbon brushes must
be replaced immediately. Always replace both carbon brushes at the
same time.
• Unscrew the carbon brush covers fig. B5.
• Remove used carbon brushes.
• Remove any carbon dust, using low pressure compressed air.
• Insert new carbon brushes (brushes should slide freely into
brushstops).
• Fit the carbon brush covers fig. B5.
After replacing the carbon brushes, it is necessary to run the
grinder without load for approx. 3 minutes so that the carbon
brushes fit into the commutator of the motor. It is recommended
that carbon brush replacement should only be carried out by a
qualified person using original parts.
Any defects should be rectified by the manufacturer's authorised service
department.
GRINDING FOLDING
The sander has a folding feature to make it easier to transport. To fold
the sander, loosen the locking mechanism fig. C9 of the hinge fig. A9
and fold the sander. To disassemble the grinder follow the above steps
in reverse order, making sure not to cut the power cord fig. C8. When
assembling the grinder, clean the seals fig. C7 from dust and other dirt.
Once assembled and cleaned, the grinder will fit into the carry bag.
