Operation
3.19 Hydraulic brake
The pedals automatically return to their initial positions as soon as they are released. This
creates sufficient hydraulic braking effect.
During downhill machine travel, the automatic hydraulic brake valves prevent the machine
from “racing”. The machine does not run any faster than the permissible travel speed.
Information!
Use the accelerator pedals to reduce the travel speed as required.
3.20 Mechanical brake
The stop brake and parking brake is designed as a spring-loaded and hydraulically actu-
ated multidisk brake. This brake is automatically applied with a certain delay after having
released the drive levers or the accelerator pedals.
Stabilizer blade as a parking brake
The stabilizer blade is used as a parking brake. Press the stabilizer blade against the
ground.
3.21 Machine travel on slopes
DANGER
Accident hazard due to tipping over or slipping of machine
on slopes!
Can cause serious injury or death.
• Travel on slopes only on firm and level ground.
• Never exceed the stability limits of the machine (maximum gradient angle
15°, maximum lateral angle of inclination 10°)
• Raise the boom about 20 – 30 cm (8 – 12 in) off the ground and position it
straight ahead at the center of the machine. In an emergency, lower the
boom immediately to increase stability.
• Do not actuate high speed on slopes.
• Do not reverse down slopes.
• Do not turn or swivel the upper carriage and the boom when driving down-
hill or uphill with a full attachment.
• Performing machine travel diagonally on slopes is prohibited.
