10 Operation traction drive
10.1 General
10.1.1 Traction drive
The machine is driven via all wheels (4x4) using four hydrostatic wheel hub drives
with hydraulic differential locks.. The transverse differential lock can be enabled at
the switch (25).
Disable the lock when driving on roads or if the chassis is set wide.
The wheel hub drives are equipped with an automatic parking brake. The spring pressure disk brake is a
safety brake that is always closed by compression springs. It is opened by the supply of pressurised oil.
The brake does not need to be adjusted, and thus is also maintenance-free.
10.1.2 Driving
Please read following rules, if the machine isn't in drive position.
Directions
Should the upperstructure be positionend in excess of 900 from the driving position, driving controls
will be in reverse order. To check the function of driving controls operate foot pedal with caution. If the
operator isn't sure in which direction the machine's moving, he has to tip softly on the foot pedal before
start driving.
Driving preparation
Prior to driving warm engine 2 - 3 minutes. Raise chassis and stabilizers off the ground. Parallel steering
stabilizers. Engage steering switch 19 to lock in steering. Place boom assembly between driving wheels.
Steering by the Joy Stick (change into steering mode)
10.1.3 Driving up steep roads
Steep roads must be navigated with the following engine setting:
1. With one speed: Maximum revolutions (2000 rpm), control the speed using the foot pedal.
2. With 2 speeds: Maximum revolutions (2000 rpm.), drive in first gear and control the speed using the
foot pedal.
In this setting, the diesel engine has adequate braking force and cannot therefore be over-revved.
