4. Rough cleaning, metal or

stone sanding

The sander is equipped with full-wave tacho-
constant electronics for:
- Soft start and restriction of the starting cur-

rent;

- Speed pre-selection and adjustment and

maintaining constant rpm upon overloading;

-  Overload protection:
A  current  clutch  actuates  upon  considerable
brief overload to switch the machine off until the
load drops down.
Upon  minor  continuous  overload  the  thermal
overload  protection  actuates,  to  reduce  mo-
tor  rpm.  The  machine  becomes  disabled.  To
resume operation after the machine has cooled

down for 2-4 minutes, first turn off and then turn

on the ON/OFF switch;

- Non-self starting safety (NVR) at restoring
the mains supply. To resume operation after
the current clutch has switched the machine off,

release the ON/OFF switch and then press the

switch again.

- Stabilizing the spindle speed.

MOUNTING THE ACCESSORIES

When mounting the sanding accessories fix the

sander spindle (1) by pressing the lock button
(3) positioned on the gear box.

WARNING:

Never press the button

(3) while the spindle (8) is still rotating!

SANDING WITH SANDPAPER

The selection of sandpaper depends on the de-

sired surface quality. For rough operations use

sandpaper with larger grit size, and for fine and

finishing operations use sandpaper with smaller

grit size to achieve surface smoothness.

We recommend using original SPARKY acces-
sories specially designed for achieving optimum
results.
Use only hook-and-loop sanding sheets.
Do not use sanding discs with diameter exceed-
ing the maximum permitted for the power tool.

Refer to power tool specifications.

MOUNTING THE ACCESSORIES fOR
SANDING WITH SANDPAPER

The  precise  and  accurate  performance  of  the
below  described  procedures  guarantees  the
reliable and safe operation with the power tool.
All instructions are important and result from our
huge experience gained during design and op-
eration of power tools for the described use.
  1.  Ensure that the power tool is unplugged.

2. Turn the machine in a way ensuring ac

cess to the operating tool. We recommend fixing

the machine in stationary position. Thus it would
be possible to use both hands for convenient
and safe assembly.
3. Clean the threaded and face surfaces of

the spindle (8) using soft cloth and brush.

4. Take out the sanding set from the pack-
ing.

5. Clean the flange (14) face surface and

arbour and the support disc (27) face surfaces

using a soft cloth and brush. The support flange

(14) is the thinner flange.

6. Place the support flange (14) onto the

spindle (8) observing the orientation - its flat

face should stick to the spindle (8) flange. In

correctly chosen flange (14) will deteriorate dust

extraction.
7. Ensure there is no dirt or foreign body be-

tween the spindle (8) face and the flange (14)

face which may hamper their contact. The pres-
ence of foreign bodies and disturbed face con-
tact are prerequisites for inexact movement of
the operating tool and increased vibration caus-
ing unsatisfactory quality of the processed sur-
face.

8. Mount the support disc (15) on the flange

(14) and ensure there are no foreign bodies be-
tween their faces.

9. Fasten the tightening nut (16) to fix the

support disc (15) to the spindle (8) firmly. It is

obligatory to observe the tightening nut (16) ori-

entation as shown on Fig. A. Otherwise tighten

ing the support disc (15) will not be possible.
10. Press the spindle lock button (3) and ro-
tate the support disc (15) clockwise until the but-

ton sinks and locks the spindle (8) movement.

11. Fasten the tightening nut (16) reliably us

ing the pin spanner (26) supplied with the ma

chine.

12. Release the spindle lock button (3) and
