Jungheinrich DFG 425 Operating Instructions Manual page 15

Hydraulic system: The gear pump of the hydraulic system is powered by motor
through a power take off of the power shift gear. The pump speed and hence the
supply volume are controlled by the accelerator pedal through the motor speed.
Hydraulic functions are controlled by the control lever through a multiple control valve.
Electrical System: 12 volt system with starter battery and AC generator with
integrated controller. A start repeat block prevents incorrect operation during start-up
and a safety switch ensures the motor can only start when the travel direction switch
is in neutral. For diesel motors, a rapid pre-heat system is installed, LPG motors have
a non-contact electronic ignition system for rapid and trouble-free engine starting.
The ignition / start switch is used to stop the motor.
Mast (5): The target has been to maximize visibility. The maximum strength steel
section are narrow, allowing for good fork visibility in particular with the three-stage
mast. The same standard has been achieved for the fork carriage.
The mast and the fork carriage run on permanently-lubricated and hence
maintenance-free angled casters.
Attachments: The trucks can be optionally fitted with mechanical and hydraulic
attachments.
