USE INSTRUCTIONS.
►
Before starting up the sander, we recommend
that you carefully read all of the instructions as
indicated
►
Please respect all regulations regarding
the prevention of accidents, health and safety
directives, laws and applicable restrictions for work
places
►
The sander must only be used by persons
who have been instructed in its use and only for the
purposes for which it has been designed.
POWER SUPPLY.
►
Make sure the power supply is adapted to
the requirements shown on the information
panel of the sander (1)
►
Using the motor at low
voltage will make it operate slowly
►
This will
reduce performance and may cause the motor to
overheat.
EXTENSION CORD.
►
If the working area is at some distance from the
power supply, use an extension cord of enough
diameter and quality.
OPERATION.
►
To turn the sander on, press the power switch
(2)
►
Move the sander in long sweeping strokes
along the surface being sanded, letting the sander
do the work (3)
►
Pushing down on the sander
slows the removal rate and produces an inferior
quality surface (4)
►
Never operate with the
sander inclined, this can damage the base and
break the sandpaper (5)
►
Be sure to check your
work often
►
This sander is capable of removing
material rapidly, especially with coarse paper
►
To
produce the best finish possible, start with coarse
grit sandpaper and change gradually to finer and
finer paper
►
A final sanding with a piece of well-
worn fine sandpaper will produce a professional
looking finish that in many cases will need no
hand sanding at all
►
The rate at which the dust
collection bag will fill up will vary with the type
of material being sanded and the coarseness of
the sandpaper
►
For best results, empty the bag
frequently and check the opening for clogging
►
When sanding painted surfaces, you may find
that the sandpaper loads up and clogs with paint
►
A heat gun will work much better to remove
paint before sanding
►
Avoid overloading the
sander
►
Overloading will result in a considerable
reduction in speed and efficiency and the sander
will become hot
►
In this event, run sander at a no-
load condition for a minute or two.
DUST EXTRACTION.
►
The sander includes a integrated dust collector.
TO EMPTY DUST COLLECTOR.
►
While holding the sander and remove the dust
collector cup
►
Gently shake or tap the dust
collector to empty
►
Put again the cup in the dust
collector
►
Sanding dust exhaust may create a
breathing hazard.
PRECAUTIONS TO TAKE WHEN SANDING
PAINT.
►
Sanding of lead based paint is not
recommended due to the difficulty of controlling
the contaminated dust
►
The greatest danger of
lead poisoning is to children and pregnant women.
CLEANING AND DISPOSAL.
►
All surfaces in the work area should be
vacuumed and thoroughly cleaned daily for the
duration of the sanding project
►
Vacuum filter
bags should be changed frequently.
FIXING THE 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 (6)
►
Align the sanding disc over the plate
so that their edges meet
►
Press the sanding disc in
place onto the base until it is firmly held in place.
SPEED SELECTOR.
►
The sander is equipped with a speed selector
►
The optimum speed adjustment for each
application mainly depends on the user’s
preferences
►
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.
MAINTENANCE.
►
The sander has been designed for a long
working life with minimum maintenance
►
Optimum use depends 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 ventilation
vents and switch levers must be dept clean and
