Danger!
Risk of electric shock.
Make the system voltage-free by switching the unit at the
master switch (17.1) to “0” and securing it against being
switched on again.
Risk of injury by unexpected exit of compressed air.
Compressed-air tanks and lines remain under pressure
even after the system has been switched off. Before
doing work on the system, it is essential that pressure is
reduced by opening the condensate drain-valve. To do
this, open condensate drain valve by a maximum of one
rotation. Then check absence of pressure at pressure
gauge at the maintenance unit (a).
Risk of injury from unexpected exit of jet of water under
high pressure. The high-pressure system remains under
pressure even when the system has been switched off.
Before doing work on the system, it is essential that the
high-pressure system is made pressureless.
Risk of eye injury from parts or dust being flung out. Do
not stand near rotating brushes. Wear protective goggles
when doing maintenance work.
