Machine travel on slopes
WARNING
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.
► Drive on slopes only with the telescopic travel gear extended (normal
operation).
► Never exceed the stability limits of the machine (maximum gradient
angle 15°, maximum lateral angle of inclination 10°).
► Raise the boom 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 during uphill or downhill machine operation.
► Do not drive downhill in reverse travel speed.
► Do not turn or swivel the upper carriage and the boom when driving
downhill or uphill with a full attachment.
► Performing machine travel diagonally on slopes is prohibited.
Stones and the humidity in the upper layer of the ground can drastically
affect machine traction and stability.
The machine can slip sideways on gravel or loose, rocky soil. The stability
of the machine can be reduced on rough terrain.
Newly filled or muddy ground can give away under the weight of the
machine, or the tracks can dig into the ground and increase the angle of
the machine (maximum gradient angle and maximum lateral angle of
inclination).
If the engine dies as you drive on a slope, immediately put the control
levers to neutral position and start the engine again.
Observe under all circumstances during uphill or downhill travel:
• Keep the drive levers near the neutral position.
• Perform slow and smooth travel movements.
• Avoid sudden travel movements.
• Reduce the engine speed.
The machine can slip even on gentle slopes if it travels across grass,
leaves, humid metal surfaces, frozen ground or ice.
