4.8.2 Steering
• The wheel loader features a fully hydraulic,
proportionally acting articulated steering.
• Priority supply of hydraulic oil to steering
through load-sensing system.
In the event of steering malfunctions,
determine the cause immediately (see
Trouble-Shooting Table) and call for
service personnel if necessary.
4.8.3 Brakes
Service and auxiliary brake
• To bring the machine to a halt, release the
accelerator pedal (19/3). The hydrostatic travel
drive then acts as an auxiliary brake.
• Operate the brake-inching pedal (19/2) as
required.
Parking brake
• Only apply the parking brake (19/9) if the
machine is stationary.
Once the parking brake is applied
(19/16), the travel drive is deactivated.
Brake-inching mechanism
• The machine features a brake-inching
mechanism altering the relationship between
travel speed and engine speed.
• When the brake-inching pedal (19/2) is
operated, travel speed is reduced - irrespective
of engine speed - until the machine comes to a
stop.
This mechanism permits sensitive driving at
maximum engine speed, e.g. when loading a
truck, where fast working cycles are required.
