7.5 MAINTENANCE

SWITCHES

Maintenance switches are located inside the control box to assist the technician when servicing the
lifting system (see fig. 8.1). These switches can be used to check the correct functioning of the
lowering valve, unlock solenoid and the hydraulic unit. As long as the control system is still functional,
the switches can also be used to check the safety margins for control.

Switch

heights of the guide bolcks so that they
become level.
