3.7 Machine travel on slopes
< 10°

OM 803 us – Edition 3.7 * 803b330.fm
WARNING Warning!
Accident hazard due to tipping over or slipping of machine!
Can cause serious injury or death.
• Travel on slopes only on firm and level ground.
• Travel 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 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 reverse down slopes.
• Do not turn or swivel the upper carriage and the boom when traveling
downhill or uphill with a full attachment.
• Traveling diagonally on slopes is prohibited.
• Traveling on slopes is prohibited if a zero-emission power unit (HPU8, for
example) is raised with the stabilizer blade.
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 travel on a slope, immediately put the control levers to neutral
position and start the engine again.
Bear in mind the following under all circumstances when traveling uphill or downhill:
• Keep the travel 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.
Preparations for traveling on slopes
Always travel straight ahead when traveling uphill or downhill.
When changing position, do not exceed a maximum gradient angle of 15° and a maximum
lateral angle of inclination of 10°.
