• 1 Service Allen e/c:6 key.
• Carrying bag.
• Safety and instruction manuals and miscellaneous
documentation.
Carefully remove the tool and all loose items from the
shipping container.
Retain all packing materials until after you have inspected
and satisfactorily operated the machine.
4. ELECTRICAL CONNECTION
Check the power supply is always the same voltage as
that indicated on the machine's specifications plate.
The machine must not be used under any circumstances
if the power lead is damaged.
A lead that is damaged or in poor condition should be
immediately replaced by an authorised technical service;
do not try to repair it yourself.
Working with a lead in poor condition can cause elec-
trical accidents.
5. ELECTRONIC CONTROLS
Smooth starting: Electronic starting controls that ensure
a smooth start and gradual increase in speed.
Controlled speed: You can set the uninterrupted disc
turning speed, from 1,000 to 1,600 rpm with no load,
by using the correct buttons (C, Fig. 1). You can this way
set the best possible sanding speed for each material.
We advise using the highest speeds when a lot of material
needs to be removed and low speeds for finer sanding
and to improve control of the machine.
6. ATTACHING THE ABRASIVE DISC
Unplug the machine.
Take off the used disc, ensuring that the sponge plate
remains in position.
Carefully align the holes in the disc (Fig. 3) with those
on the plate and press the disc so that it is held in place
by the Velcro on the plate.
Do not attempt to attach any accessory
other than sandpaper, this may lead to
damage to the machine.
Always take care to ensure that the
sandpaper is well-centered on the bac-
king pad, and double check to confirm
that it is fully adhered. Off-center or
poorly adhered sandpaper will lead to
excessive vibration which could damage
the machine.
NOTE: The sponge pad has 2 different hook profile
types. The black side is finer hook, the white side is
16
coarser hook. Choose the side which adheres best to
your sandpaper (Fig. 4)
7. CHANGING THE SPONGE PLATE
The sponge plate should be perfectly smooth for proper
sanding and good results.
If the pad has become misshapen or damaged by work,
the sanding will be irregular and poor quality. You should
change the pad immediately when it has been damaged.
To replace the sponge plate, unplug the machine from
the mains.
The sanding plate has Velcro on both sides, therefore to
change it you have to pull it until it comes off the base
plate and replace it with a new one. (Fig. 4).
Make sure the holes in the sponge plate
are perfectly aligned with the slots in the
Base. An incorrect alignment will cause
excessive vibration.
Use only original replacement sponge
plates. Other types of external fabrication
do not work properly with this tool.
8. CHANGING THE PLATE COVER
Cover functions: The brush on the edge of the plate
cover has the dual function of keeping the abrasive
disc properly aligned with the surface it is sanding and
to enable the vacuum cleaning system to work more
effectively.
The brush on the cover becomes worn with constant
machine use, no longer guaranteeing the correct position
of the plate or effective dust collection. When this occurs
you should change the whole cover.
Change the cover in the following way:
• Unplug the machine.
• Hold the sponge plate with one hand and use the
other hand to insert the Allen key provided inside the
spindle on the plate, first break free the center bolt (M,
Fig. 5) clockwise. Then only use the Allen key to hold
the center bolt from turning and spin off the sanding
plate counterclockwise.
Remove the 8 screws (N, Fig. 6) to remove the sanding
plate cover from the sanding cover base.
• Now press the cover down against the spring (Fig. 4)
and with the help of some special pliers for retaining
rings, take off the retaining ring fastening the cover.
• Finally, remove the dust collector tube with care (Fig.
5), take off the plate cover and replace it, turning it in
the opposite direction for attachment.
9. VACUUM CLEANER PIPE INSTALLATION
• Unplug the machine.
