Testing the Proximity-switch
The Proximity-switch detects if the machine is sucked against the surface to be treated.
In the unlikely event that the machine comes from the wall during blasting, the proximity-switch will
immediately close the shotvalves at double speed, minimising the damage and danger.
Make sure the dusthose is connected and the dustcollector is ON.
Observe the lights on the
remote control and
proximity-switch.
Place a metal object in front
of the proximity-switch.
The lights on the remote
control and proximity switch
should light up.
Remove the metal object.
The lights on the remote
control and proximity switch
should go out.
DO NOT PROCEED IF THE PROXIMITY-SWITCH DOES NOT WORK!
