Low Oil Pressure Alarm
The low oil pressure alarm sounds when the engine oil
pressure is near the lower limit for safe engine operation.
If the alarm sounds, lower the platform to the ground and
then turn the engine off.
• If the engine oil pressure falls below a safe operating
value the engine will shut off.
• The engine can be restarted with low oil pressure,
but it will only run for a few seconds before it shuts
off again.
• Do not restart the engine until the condition that
caused the low oil pressure has been corrected.
All Motion Alarm
The all motion alarm sounds, in short beeps, anytime the
machine functions are being operated. The alarm is used
to warn personnel in the work area to stand clear.
Horn
The optional horn may be used to warn personnel on the
ground. The horn button is on the right side of the upper
control panel (refer to Figure 4.7). The horn is operational
when the machine is set up for operation from the upper
controls.

Drive Motion Alarm
An optional drive motion alarm may be provided on the
machine. When the drive/steer control is moved out of
neutral the alarm sounds, in short beeps, to warn person-
nel in the work area to stand clear.
Flashing Light
An amber flashing light may be located on the top of
the boom near the base end (refer to Figure 4.8). The
flashing light warns personnel that the aerial platform is
in the area.

Tilt Alarm
If the aerial platform chassis is out of level more than
five degrees when the main boom is raised or extended,
an alarm will sound. The tilt alarm is located under the
upper control panel.
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not drive or position the aerial platform for
elevated use near any drop-off, hole, slope, soft or
uneven ground, or other tip-over hazard.
Retract and lower the booms and then drive to a level
surface when the tilt alarm sounds.
The tilt alarm is for added protection and does not
justify operating on anything other than firm, flat, level
surfaces.
Engine Protection Systems
A constant tone alarm will sound to warn against high
engine temperature or low oil pressure.
The engine will shut-down:
• if the operating temperature exceeds a preset level
• or if the oil pressure is too low for safe operation.
High Engine Temperature Alarm
If the coolant in a Cummins or GM engine exceeds the
engine operating temperature an alarm will sound and
the engine will shut off.
If the oil in a Deutz engine exceeds 230°F (0°C) an
alarm will sound and the engine will shut off. Any time
there is no alternator current being produced, an alarm
will sound and the engine will shut off. This prevents high
engine temperature if the fan belt breaks.
Do not restart the engine until the condition that caused
the overheating has been corrected.
