DANGER!
Risk of injuries!
Danger due to dropping load!
The load can drop uncontrollably if the volume
flow of the auxiliary hydraulic is too high.
The load can drop uncontrollably if the pressure at
the auxiliary hydraulic raises too quickly.
The load can drop uncontrollably if the motor cavi-
tates.
Installation:
Install 3-port / 2- way control valve (12), Auxiliary hydraulic
system or hand pump (10) and Check valve (13) according
to hydraulic diagram.
When oil is supplied from the auxiliary hydraulic or the
hand pump to the emergency brake release, it flows into
the main circuit through an orifice inside the motor housing.
To avoid overflow of the main tank the auxiliary hydraulic or
the hand pump shall be connected to the same tank.
