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. If you have already used the power tool
with another accessory - remove it following the
steps described in the corresponding section for
this accessory.
4. Clean the threaded and face surfaces of
the spindle (8) using a soft cloth.
5. Take the flange (20) for operation with a
diamond disc and place it on the face of the
spindle (8). Please note that flange (20) for
operation with a diamond disc is different from
flange (14) for operation with sandpaper. The
visual difference is in their thickness - the flange
for operating with a diamond disc is thicker. The
support flange (20) is thicker than flange (14). If
the flange is selected improperly operation will
be impossible as the spindle will project consid-
erably above the diamond disc surface.
6. Ensure there is no dirt or foreign body be-
tween the spindle (8) face and the flange (20)
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.
7. Mount the diamond disc (21) so that its
bore enters the flange (20) step.
8. Fasten the nut (16) in order to fix firmly the
diamond disc (21) to the spindle (8). It is obliga-
tory to observe the orientation of the fixing nut
(16) as shown on Fig. B. Otherwise the nut (16)
will not fix the diamond disc (21) reliably.
9. Press the spindle lock button (3) and ro-
tate the spindle (8) clockwise until the button
sinks and locks the spindle (8) movement.
10. Tighten firmly the nut (16) using the pin
spanner (26) supplied with the machine.
11. Release the spindle lock button (3). En-
sure that the button (3) has returned in its ini-
tial position and does not lock the spindle (8)
movement. In case the button (3) still locks the
spindle (8), rotate the spindle (8) or the diamond
disc (21) by hand until the button (3) has been
released and returned in its initial position.
12. Remove the pin spanner (26).
13. Turn the machine with the diamond disc
facing downward.
14. Plug the power tool.
15. Slide the ON/OFF switch (5) forward to
switch on the machine.
16. Let the machine operate at no load for
approximately one minute not allowing the dia-

mond disc (21) to contact any surface.
17. At the event of increased vibrations or
other symptoms not typical for operation, stop
the machine immediately and search for the
reason. If you can not detect the reason your-
self - contact the nearest authorised SPARKY
service centre. Operating with a faulty machine
may cause an accident!
18. If no trouble is detected then you can start
operation.
REPLACING THE DIAMOND DISC
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. Press the spindle lock button (3) and ro-
tate the diamond disc (21) by hand clockwise
until the button sinks and locks the spindle (8)
movement. Remove the tightening nut (16) us-
ing the pin spanner (26). After removing the
nut ensure that the button (3) has returned in
its initial position and does not lock the spindle
(8) movement. In case the button (3) still locks
the spindle (25) rotate the spindle by hand until
the button has been released and returned in its
initial position.
4. Remove the diamond disc (21) and flange
(20).
5. Clean the accessories for operation with
the diamond disc and store them for future use.
6. Follow steps 4 - 18 from section „Mounting
the diamond disc".
