UNSAFE JOBSITE HAZARDS
• Do not operate the machine on
surfaces, edges or potholes that
cannot bear the weight of the
machine. Raise or extend the
boom only when the machine is
on firm, flat ground.
• Never travel on uneven terrain or
unstable surfaces or in other
dangerous conditions when
raising the platform.
• When the machine is on rough
ground, with gravel or other
uneven surfaces, or near holes
and steep slopes, maintain a
minimum distance of 0.6m (2ft)
and reduce the speed.
• Do not use the tilt alarm as a
horizontal indicator. The tilt alarm
on the platform will sound only
when the machine is heavily tilted.
If the tilt alarm sounds:
– Carefully lower the platform
and move the machine to firm
level surface. Do not rotate the
turntable while lowering the
mast. Do not modify the level
or limit switches.
• Do not drive the machine
exceeding 0.6 km/h (0.37 mph)
with platform raised.
• If the machine can be used
outdoors, never operate it during
strong winds or gusts. Do not lift
the platform when the wind speed
exceeds 12.5 m/s (28 mph). If the
wind speed exceeds 12.5 m/s (28
mph) after the platform is lifted,
fold the platform and do not
continue to operate the machine.
• Do not use any device that may
increase the wind load on the
machine.
• Do not drive or lift the machine on
slopes, steps or vaulted surfaces
that exceed the maximum
gradeability of the machine.
