breathing problems. The speed at which the bag
fills will depend on the material being sanded and
the thickness of the sandpaper used. Clean the
bag regularly to guarantee the best results.
PROTECTIVE BRUSH FOR SANDING DISC.
The sanding base is surrounded by a protective
brush (11). This brush enters into contact with the
surface being sanded before the sandpaper, gua-
ranteeing that both come into contact with each
other in parallel, avoiding damage caused by the
sandpaper accidentally rubbing against the work
surface. The protective brush also acts as a ba-
rrier against the dust created by the sander while
in operation, containing it so that it is gradually eli-
minated by the external vacuuming system. If the
protective brush is damaged or worn, it must be
replaced.
SPEED SELECTOR.
The sander is equipped with a speed selector (12).
The slowest speed is in position "1" and the fastest
on "6". The optimum speed adjustment for each
application mainly depends on the user's preferen-
ces. In general, a high value is preferable for hard
materials and a lower value for soft materials. The
speed at which material is removed increases with
the spin speed.
OPERATION.
Connect the external vacuum system. Once con-
nected to the power supply, press the power button
to start the sander (13). Place the sander carefully
over the surface to be sanded, applying sufficient
pressure to light the sanding base over the working
surface. Apply more pressure so that the sandpa-
per comes into contact with the surface and move
the sander with a to and fro motion to gradually re-
duce the working surface (14). Only use the force
required to maintain contact between the sander
and the working surface. Excessive pressure may
cause damage to the surface being sanded. While
the sandpaper is in contact with the working surfa-
ce, the sander must be in regular, constant motion
to avoid unwanted marks on the working surface.
Make sure the sandpaper does not come into con-
tact with sharp or pointed edges that may cause
damage to the sander. Check the results regularly,
as the sander is capable of removing material very
quickly, especially when using coarse sandpaper.
LED LIGHT FUCTION.
The sander is equipped with a LED light fuction
(15). To use this fuction, press the LED light power
button (16).
FIXING SANDING DISCS IN PLACE.
Disconnect the sander from the power supply before
making any adjustments or replacing accessories.
The sanding discs are held in place with velcro (17).
Align the sanding disc over the plate so that their
edges meet (18). Press the sanding disc in place
onto the base until it is firmly held in place (19).
FOLDING.
To fold the sander, simply release the fastening pin
located on the right side of the auxiliary handle.
MAINTENANCE.
The sander has been designed for a long working
life with minimum maintenance. Optimum use de-
pends on correct care of the sander and regular
cleaning. To prevent accidents, always unplug the
sander from the power source before cleaning or
performing any maintenance. The sander may
be cleaned effectively using compressed air after
each use. If compressed air is not available, use a
brush to remove dust from the sander. Motor ven-
tilation vents and switch levers must be dept clean
and free of foreign matter. Do not attempt to clean
by inserting pointed objects through openings. Ce-
tain cleaning agents and solvents damage plastic
parts, among them are gasoline, carbon tetrachlo-
ride, chlorinated cleaning solvents, ammonia and
household cleaners containing ammonia. Do not
use any of these to clean the sander.
