Purging the cylinders
Purge the lift cylinders by fully lower-
ing the platform a few times. You may
have to lift the truck to fully lower the
platform.
For tilting cylinder model
The tilt cylinders can be purged by rais-
ing the platform fully against the vehicle
body and then tilting all the way down.

Transport lock
Electric hose rupture valves serve as
locks for the platform. The lock opens
automatically if the down function is
actuated from the control device. The
valves are non-return valves that let
fluid in from the cylinders but not out be-
fore they are actuated by the flow from
the lowering valve. The platform is thus
hydraulically locked during transport.
