The blasting chamber illumination is activated when the main switch is switched on:
1. by pressing one of the keys (5) or
2. by pressing the pedal switch or
3. by withdrawing one of the blasting stylusses (31) from the holder (44).
The blasting chamber illumination remains switched on for as long as a blasting stylus is
withdrawn.
The vacuum extraction switches on automatically by actuating the pedal switch while the main
switch is switched on and a blasting stylus is withdrawn. The vacuum extraction switches off
after approximately 7 seconds if the pedal switch is no longer actuated (the time can be set).
3.6 Activating the desired blasting system (automatic recognition)
(see Fig. 2 page 5 and Fig. 4 page 8)
1. All blasting styluses (31) must be inserted in the blasting stylus holders (44) according to
their color marking.
2. By removing the desired blasting stylus from the blasting stylus holder, the corresponding
blasting system is automatically activated.
3. The operating parameters (dosing the blasting agent amount and operating pressure), as
adjusted during last use of this blasting system, are taken over and indicated in the display
(10).
4. The sand blast is activated with the foot pedal.
Attention
If the front cover (40) or the cover (23) of the blasting agent container chamber is not
completely closed, the sand blast cannot be activated. After activating the foot pedal "
Close
cover
” is indicated in the display (10).
5. Before a new blasting system can be activated, the blasting stylus previously removed must
be put back in the blasting stylus holder.
Remark
The respectively active blasting system is indicated with the control lights in the push buttons
(5/...) of the relevant operating field.
Remark
If all blasting styluses (31) are removed from the blasting stylus holders (44), the desired
blasting system can be activated with the push buttons (5/...). See "3.11.6 and 7 LED-
Display”.
3.7 Adjusting the operating pressure (blasting pressure)
(see Fig. 4 page 8)
The operating pressure is set separately for each blasting system with the corresponding
operating pressure regulator (9) and is indicated in bar in the display (10), see section
"3.11.5”). The relevant setting is maintained for the blasting system concerned until it is
changed.
Depending on the requirements, it is possible to work with 0.5 bar to 7 bar. Normally, a
maximum operating pressure of 5 bar is sufficient.
Also observe pre-pressure regulator setting, see 3.2.2
3.8 Dosing the blasting agent amount
(see Fig. 4 page 8)
The blasting agent portion in the spot blast of the relevant activated blasting system is
adjusted with the push buttons (6) and (7) and indicated in the LED display (10) with "
Volume
"
and a figure from "
0
" to "
9
".
−
value "
0
” means minimum of blasting agent portion
−
value "
9
” means maximum of blasting agent portion
