OM 75Z3/8003 US – Edition 4.0 * 7003b110.fm 1-5
Introduction
Travelling drive
The diesel engine permanently drives the twin axial variable displacement pump whose oil
flow is sent to a hydraulic motor for each track drive.
Operating hydraulics
The diesel engine also drives the joint gear pump for the operating hydraulics. The oil flow
of this pump depends on the diesel engine speed only.
Shock cartridges (option)
The auxiliary hydraulics are equipped with a Shock cartridge to compensate pressure
peaks in the hydraulic system.
Cooling system
The indicator lights in the instrument panel of the machine ensure constant monitoring of
the engine and hydraulic oil temperature, as well as of the coolant temperature and level.
Cab (ROPS and FOPS)
The cab has been specially designed for protection in case of an accident.
• ROPS (Roll Over Protective Structure) tested cab.
• FOPS (Falling Object Protective Structure) – option
Do not modify or attempt to repair the ROPS cab or ROPS structure. Any permanent
deflection of the ROPS is a failure mode and the cab or structure must be replaced to
ensure future protection to the operator space in the event of a tipping incident. Contact a
Wacker Neuson dealer for instruction or clarification.
The ROPS is a special safety device designed and produced to exacting material and
assembly standards for certification. Bending, heating, welding, cutting, or drilling holes in
the ROPS will reduce the protection performance in a tipping incident.
Fasten your seat belt, otherwise you can be thrown around or even outside the cab and
crushed. Therefore always fasten your seat belt as you drive and work with the machine.
Tighten the seat belt before starting work with the machine.
