3. CONTENTS STANDARD EQUIPMENT
You will find the following items inside the box:
• LPC97S long-reach dry wall sander.
• Dust collecting pipe (4 m).
• 1 Service Allen key.
• 1 Abrasive disc grit 80.
• D-handle.
• Carrying bag.
• Safety and instruction manuals and miscellaneous
documentation.
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 650 to 1,600 rpm with no load, by
using the thumb wheel (A, Fig. 1). You can in 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 (B, Fig. 2) with those
on the plate and press the disc so that it is held in place
by the Velcro on the plate..
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
2
change it you have to pull it until it comes off the base
2
plate and replace it with a new one. (C, Fig. 3).
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, and turn it by just 1/8 of a turn
to unlock the plate (Fig. 4). Keep the Allen key in the
spindle to prevent it turning and take out the sponge
plate by unscrewing it counterclockwise.
• Now press the cover down against the spring (Fig. 5)
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.
6), take off the plate cover and replace it, turning it in
the opposite direction for attachment.
9. FITTING THE D-HANDLE
• Remove the two knobs (F, Fig. 7) and take off the
cover (G, Fig. 7).
• Fit the D handle in the required position on the
column (Fig. 1).
• Fit the cover again (G, Fig. 7) and firmly fasten it with
the two knobs (F, Fig. 7).
10. VACUUM CLEANER PIPE INSTALLATION
• Unplug the machine.
• Fit the bayonet connector (D, Fig. 8) into the swivel
connector (E, Fig. 8) on the end of the handle.
