WARNING! The following safety messages
address a potential Entanglement Hazard
while the machine is travelling:
• Verify there are no people within the
travelling path of the machine or around

not enter the travelling path or the working

• When reversing the machine, pay attention
to your footing. Decrease machine to a

WARNING! The following safety messages
address a potential Tip Hazard while the
machine is travelling:
• Never travel when a person or load is on
the travelling dolly or boom. Do not allow a
person to sit or stand on the travelling
dolly or boom while moving the machine.
Do not travel with a load placed on the
travelling dolly or boom.
• Never make sudden directional changes
while the machine is travelling. Reduce
speed slowly and allow the machine to
stop before changing direction.
• When travelling over uneven ground, use a
slow travel speed and avoid changing
direction.
WARNING! The following safety messages
address a potential Tip Hazard while the
machine is travelling on slopes (hills):
• The tilt alarm buzzer sounds if the machine
tilts by 15° or more from front to back or
sideways when travelling. Avoid travelling
over steeper slopes if the alarm buzzer
sounds.
• When travelling on a slope, the operator
should always stand on the upper side of
the machine.
Fig. 4-71
• Always travel slowly and use caution when
using the travel levers on a slope. Do not
drive the machine too fast for the
conditions of the slope.
• Avoid travelling across slopes and
changing travel direction of the machine
while on slopes. When slopes must be
crossed, and it is judged safe to do so,
proceed with extreme caution and at a low
speed. Never exceed 10° when travelling
across a slope.
