Dust Extraction; Pre-Selecting The Belt Speed - Redstone RS 976PB Instrucciones De Uso

8. Run the sander for a minute or so to ensure
correct alignment before using the sander on
a work piece.
WARNING: Do not continue to use the
sander with a sanding belt that is overworn or
damaged.
WARNING: Do not use the same sand-
ing belt for wood and metal. Metal particles
become embedded in the belt and will scour a
wooden surface.
SELECTING THE RIGHT GRADE OF
SANDING BELT
1. Different grades of sanding belt can be pur-
chased from your local hardware store. Typi-
cal grades are Coarse (40 grit), Medium (80
and 100 grit) and Fine (120 grit).
2. Use Coarse grade to remove rough finishes,
Medium grade to smooth the work and Fine
grade to finish it off.
3. It is best to make a trial run on a scrap piece
of material to determine the optimum grades
of belt for a particular job.
4. In order to take full advantage of your sander,
always purchase good quality belts.
NOTE: After sanding with a belt sander, an orbital
sander should be used to give a better surface fin-
ish.

PRE-SELECTING THE BELT SPEED

The necessary belt speed can be pre-selected
with electronic regulator thumbwheel (12), even
during operation.
The optimum belt speed depends on belt grit
and processed material and can be determined
through experience.
Recommended speed values are shown in the
table on page 56.
SANDING
1. These sanders are designed for sanding
wood, metal, plastic and similar materials.
They are used mainly for quickly removing
a large amount of material. Do not use these
sanders for sanding magnesium.
2. Ensure that the belt is in good condition.
3. Plug in the tool to the power socket.
4. Adjust the necessary speed by rotating the
regulator thumbwheel (12). The maximum
speed corresponds to the symbol G, and the
16
EN
minimum speed - to symbol A. Sanding ef-
ficiency and surface quality are determined
by belt grade and speed. The higher the belt
speed, the more material is removed and the
finer the sanded surface.
5. Bring down the sander onto the work piece
and apply light pressure. (Fig. 7)
6. Pull up the trigger and allow the belt to reach
full speed before moving it across the work.
7. Press the lock on button (4) if you require con-
tinuous operation.
8. Sand with the grain, in parallel overlapping
strokes.
9. To remove paint or smooth very rough wood,
sand across the grain at 45º in two directions,
and then finish parallel with the grain.
10. Use the front roller (8) only to sand corners or
irregular shapes.
11. Lift the sander off the work before switching
off.
12. Remember to keep your hands away from the
moving belt, as it will continue to move for a
short time after the machine is switched off.
13. Wear safety goggles, a dust mask and ear-
muffs.

DUST ExTRACTION

1. Disconnect the plug from the power supply.
2. Firmly push the plastic nozzle of the dust bag
(3) onto the dust extraction port (11). (Fig. 8)
3. Before removing the dust bag, first disconnect
the plug from the power supply.
WARNING: For optimum dust removal,
empty the dust bag when it is no more than half
full. Do not use the dust bag when sanding met-
al. The hot metal particles could cause residual
wood dust or the bag itself to catch fire.
Cleaning the bag: Dismount and empty the dust
bag, tapping it gently to remove dust. On occa-
sion, slip the bag off of the frame and turn bag
inside out. Brush dust off of the lining using a soft
brush.
4. A vacuum cleaner adapter can be used to
connect a household vacuum cleaner or
workshop dust extraction system to the sand-
er.
5. An adapter is fitted into the dust extraction
port (11).
