PREPARATION FOR WORK
ATTACHING THE ADDITIONAL HANDLE
It is recommended to use the additional handle for the sander. The
additional handle ( 8 ) is installed in one of the holes in the sander
housing ( fig. A ). If the sander is held with both hands during
operation (also using the additional handle), the risk of losing
control of the tool is much lower.
FASTENING THE SANDING PAPER
The sander has a working disc with the so called Velcro, which allows
for an easy and quick replacement of the sanding paper.
•
Move the sanding paper to the working disc (
10
) so that its holes
„ a ” coincide with the holes of the working disc and press it to
ensure efficient dust extraction ( fig. B ).
• In order to remove the sanding paper, just peel it from one side,
and then pull it all the way ( fig. C ).
Use perforated sanding paper, so that dust can escape through
the holes in the working disc to a dust extraction system. Each
time the sanding paper is replaced, clean the working disc
removing all dust and dirt using a brush.
DUST EXTRACTION
•
Insert the suction hose end onto the duct extraction connector
( 4 ) ( fig. D ).
• Connect the other end of the suction hose to a dust extraction
system, such as a dust bag or workshop vacuum cleaner.
•
Set proper suction force by turning the suction adjustment dial (
7
)
counter-clockwise or clockwise ( fig. E ).
FITTING AND ADJUSTING THE ARM BELT
Switch off the sander motor, when fitting or adjusting the arm
belt.
The proper adjustment of the arm belt can facilitate operation to
a great extent. The arm belt is especially useful when working at a
height.
• Put the snap-hooks in the hooks of the arm belt ( 1 ).
• Adjust the length using the arm belt buckle ( fig. F ).
OPERATION / ADJUSTMENTS
The mains voltage must correspond to the value specified on the
sander nameplate.
Switching on
- press the switch button (
6
).
Switching off - release the pressure on the switch button ( 6 ).
The switch lock (continuous operation)
Switching on:
• Press the switch button ( 6 ) and hold it in this position.
• Press the switch lock button ( 5 ) ( fig. G ).
•
Release the pressure on the switch button (
6
).
Switching off:
•
Press and release the pressure on the switch button (
6
).
SPEED ADJUSTMENT
The speed adjustment dial is located on the sander housing ( 3 ). The
speed is selected according to the needs (depending on sanding
paper used, workpiece hardness, type of work, etc.). Rotate the
speed adjustment dial ( 3 ) to increase or decrease the working disc
speed ( fig. H ).
WORKING WITH THE SANDER
Sanded surfaces should be dry, free of foreign bodies, such as
screws, nails, bolts, etc.
The sander should be held firmly with both hands.
• Switch on the sander and wait until the working disc reaches the
maximum speed.
•
Apply the entire surface of the working disc to the sanded surface
(the moving cover of the working disc will automatically fit tightly
to the surface).
• Putting a moderate pressure, move the sander on the sanded
surface making circular movements or alternately crosswise and
lengthwise.
•
An excessive pressure does not increase the sanding efficiency,
but may cause an early wear of the sander components and
sanding paper.
• When the working disc is moved away from the sanded surface, it
will cause dust to escape outside the device and into the room, in
which the work is carried out.
•
The efficiency and quality of the sanded surfaces depends to a
large extent on a sanding paper used and pressure applied. A type
of sanding paper is best selected by trial and error method.
• When the sanding is being completed, lower the pressure and
switch off the motor.
• Sanding paper should be replaced, when you notice it is worn.
• Make periodical breaks in operation.
Do not switch on the sander, if the working disc leans against the
sanded surfaces.
EMPTYING THE DUST BAG
When the dust bag becomes full, the suction force is reduced.
• To empty the dust bag, slide out the strip in the lower bag section
and remove its content (plaster dust).
•
When the dust bag is empty, slide the strip back into the guide to
cover the entire hole.
OPERATION AND MAINTENANCE
Before any adjustment, maintenance or repair works are
commenced, disconnect the tool from the mains.
• The sander should be always kept clean.
• Do not use water or other fluids for cleaning.
• The sander should cleaned with a brush.
• Venting slots should be cleaned on a regular basis not to overload
the sander motor.
•
When the commutator sparks excessively, check the condition of
motor carbon brushes.
• The sander should be stored in a dry place and out of reach of
children.
REPLACING THE WORKING DISC
A worn or damaged working disc should be immediately replaced.
• Loosen the clamping screw of the working disc ( 10 ) ( fig. I ).
• Replace the working disc with a new one and fasten with the
screw.
REPLACING THE CARBON BRUSHES
Worn (shorter than 5 mm), burnt or broken motor carbon brushes
should be immediately replaced. Both carbon brushes should be
always replaced at the same time.
•
Loosen the covers of the carbon brushes (
2
).
•
Remove the worn carbon brushes.
• Remove any carbon dust using compressed air of a lower pressure.
• Insert new carbon brushes (brushes should easily slide into the
brush holders).
• Fasten the covers of the carbon brushes ( 2 ).
After the carbon brushes are replaced, switch on the sander
without any load for approximately 3 minutes to make the carbon
brushes fit the motor commutator. Carbon brushes should be
replaced by a qualified person using original spare parts only.
All types of faults and defects should be eliminated by an authorised
service of the manufacturer.
