Lubrication And Cleaning - Virutex RT188N Manual De Instrucciones

sandpaper is fitted, giving a high-quality finish.
Its two movements (rotary and orbital) means smoothing
or finishing operations can be done quickly, leaving a
completely smooth, scratch-free surface.
Its specifications make it ideal for delicate sanding with
varnishing jobs.
The sander is fitted with a sanding dust collection system
and a duct collection bag.
6. PREPARING THE MACHINE
Place the sanding disc on plate "A" (Fig. 1) and match
up its holes with those on the plate.
If the plate has an adhesive base, carefully remove the
protective paper on the disc to prevent dirt coming into
contact with the adhesive part and exert pressure on
the disc until it is well attached.
Before starting work, check that the whole surface of
the disc is well stuck to the plate.
Should the discs not have suction holes, these may be
made by copying those on the plate.
7. STARTING UP
Before plugging in the machine, ensure that the power
supply voltage is the same as that stated on the machine
specifications plate. Hold the machine firmly and push
switch "B" (Fig. 1) forward to the on position. To stop
the machine, simply press the back of the switch and it
will return to the off position.
Place the machine over the surface to be sanded and
work the surface until the required finish is obtained.
You do not need to exert much pressure on the machine
while working as the best finishes are obtained using
just the weight of the machine itself.
The electronically regulated speed allows you to work
at the most appropriate speed for each surface and
sandpaper. This is particularly useful for heat-sensitive
surfaces, which require lower sanding speeds. To adjust
the speed, turn button "D" to the required working
speed (Fig. 2).
8. CHANGING THE SANDING PLATE
Unplug the machine from the electrical
outlet before performing any mainte-
nance operations.
Remove the sanding disc from the sanding plate (A) (Fig.
29 and remove screw "E" using the ALLEN key e/c: 6 mm
supplied with the machine. To attach a new plate, carry
out the same operation in reverse.
9. CONNECTING THE MACHINE
TO AN EXTERNAL DUST COLLECTOR
To connect the machine to dust collectors AS182K,
AS282K or another external suction source, the dust
collector attachment ref. 6446073 (optional accessory)
must be attached. To do this, remove collection bag "C",
and fit nozzle "G" of the dust collector attachment in
its place (Fig. 3).
The chosen external suction source may then be hooked
up to the other end of the suction connection.
10. MAINTENANCE OF BRUSHES AND COLLECTOR
Unplug the machine from the electrical
outlet before performing any mainte-
nance operations.
Brushes should be changed when they have a minimum
length of 10 mm.
Changing Brushes
Remove screws "H" (Fig. 4) that fasten the side covers
"I" and detach both. Remove the brush-holder "J" with
small screwdriver "K", using one of the brush-holder
side tabs to lever it out.
Push back the end of spring "M". Keep it in this position
to extract the brush and replace it with a new genuine
VIRUTEX brush.
Reinsert the brush-holder, ensuring that it is firmly
positioned in the casing and that each of the brushes
exerts a small amount of pressure on the collector.
Re-attach the covers "I" with the corresponding screws,
making sure that no wires get caught in the process.
It is advisable to allow the machine to run for 15 mi-
nutes in order to ensure that the brushes have properly
settled into place.
If the collector shows signs of burns or
protuberances, it should be repaired by
VIRUTEX Technical Service. Never use
emery paper for this operation. Keep the
lead and plug in good working condition.

11. LUBRICATION AND CLEANING

The machine comes fully lubricated from the factory
and does not require special care during its working life.
Always clean the machine carefully after use with a
dry air blower.
Keep the power cable in perfect condition.
Keep the machine's vent and cooling openings clean
and unobstructed.
12. NOISE AND VIBRATION LEVELS
The noise and vibration levels of this device have been
measured in accordance with European standard EN
