Operating on Inclines
WARNING
• Operating on an incline may cause the machine
to become unstable.
• Use caution when operating the machine on
inclines and use a lower engine speed.
• Operate the machine slowly and monitor
machine movement.
• Do not travel on an incline with the bucket loaded
or with a lifted load.
• Do not swing a loaded bucket toward the
downhill direction.
• Build a platform on an incline so the machine can
be operated on a level surface.
Failure to follow these warnings could result in
death or serious injury.
Observe the following when operating a machine on an
incline:
• Do not travel on an incline exceeding 15° (26.8%) side
to side, or 35° (70%) fore and aft.
• The hydraulic tank must be at the proper operating
level.
• Avoid holes, rocks, extremely soft surfaces, and other
obstacles that might subject the machine to undue
stresses or possible tip-over.
• Position the bucket 16 in. to 20 in. (20 cm to 30 cm)
above the ground while traveling.
