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
