chemical agents which are known to cause cancer,
congenital and other similar defects. Some examples
of the chemical agents are given below: the lead in
lead-based paint, crystalline silica from bricks and
cement and other masonry products, and also arse-
nic and chromium from chemically treated wood. The
risk deriving from this type of exposure varies and
depends on the frequency with which this type of
work is carried out. In order to reduce exposure to
these chemical agents: work in a well ventilated area
and work with approved safety equipment, such as
face masks which are specially designed to filter out
microscopic particles.
WARNING! Pregnant women and children should not
enter any area where paint is being sanded until it has
been thoroughly cleaned. Pregnant women and chil-
dren are at greater risk from lead poisoning.
BRIEF DESCRIPTION
This polisher has been designed to polish all types of
construction and industrial surfaces.
BEFORE USING THIS TOOL
Before using the tool, make sure the mains voltage is
correct: it must be the same as that on the specification
label. Machines with 230V can also be connected to a
220-V mains supply.
FITTING SAFETY DEVICES
WARNING! Always unplug the machine before carrying
out work on it.
Use of the auxiliary handle is obligatory in order to ensure
greater control and safety when handling the tool.
FITTING THE ACCESSORIES (DISCS AND WHEELS)
WARNING! For safety reasons, the machine should
always be unplugged from the mains before changing
the disc or wheel. Always wear safety goggles.
WARNING! Never press the blocking button C when the
machine is running. The shaft must have stopped com-
pletely before the blocking button is pressed.
To assemble the foam plate, proceed in the following
manner:
1. With hexagonal key, unscrew screw E (Fig.2) and
remove the washer.
2. Position the Velcro plate.
3. Replace the washer and screw on the screw with the
help of the hexagonal key.
4. Once the disc is fitted, check that the blocking button
has returned to its original position due to movement
of the incorporated spring.
STARTING THE TOOL
WARNING! Check that the mains voltage is the same as
that in the machine's specifications.
Plug the machine in with the switch off.
Start the machine by turning the switch A to position
"ON". To switch off, do the same in reverse.
Constant electronic performance and speed adjustment
The built-in module permits:
- Soft start.
- The maintenance of a practically constant rated speed
up to rated power.
- An overload protection system by means of current
cut-off in the case of motor overload, in which case the
burring machine shuts down and re-starts when the
grinding pressure has been reduced.
The electronic speed regulator enables the speed to
be set to different positions from 1 to 6. The most
appropriate speed should be selected according to the
part to be polished.
PRECAUTION: The speed regulator can only be turned
to position 6 and then be returned to position 1. It must
never be forced beyond 6 or 1, since this could cause
damage to the machine.
Overload protection
The motor will stop if an overload occurs. The ma-
chine should be immediately removed from the piece
being worked and allowed to operate off-load at
maximum revolutions during some thirty seconds in
order to cool the motor.
WORKING INSTRUCTIONS
Do not use the sander without the abrasive disk.
To dry sand walls
Turn on the sander.
Place the sander lightly on the work area.
Apply only the pressure necessary to maintain the
abrasive disk flat against the work area.
Maintain the movement of the sander while the disk is in
contact with the work area. Use constant and broad
movements.
Attention: do not let the spinning disk touch sharp
protrusions, screws, nails, etc., because they could
cause damage.
ATTENTION: limit of work pressure.
The tool always indicates beforehand its maximum work
limit; this is seen by uncontrollable vibrations of the
transmission cable due to pressure, revolutions or type
of abrasive unsuitable for the work surface.
To avoid breaking the transmission cable, when un-
controllable vibrations are detected, remove the plate
from the work surface for the amount of time neces-
sary for the machine to recover (3-5 seconds), start
working again moderating the pressure or regulating
the speed of the tool.
Heavy force should never be applied to the ma-
chine. Excessive pressure may lead to jams, motor
over-heating, burning of the part being polished and
back-kicking.
Use sandpaper discs which are suitable for the surface
to be worked and the required results.
Always maintain the abrasive disk parallel to the work
surface.
PRECAUTION: During polisher operation, the elec-
trical cable should always be kept behind to prevent
it being trapped.
DUST EXTRACTION
WARNING! Always make sure that the tool is switched
off and unplugged before fitting or removing any dust
extraction device.
Dust extraction keeps the workplace clean, prevents
dust build-up in the air and facilitates waste elimination.
