High Engine Temperature Alarm
If the coolant in a Ford or Cummins 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 (110°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.
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. Do not restart the engine until
the condition that caused the low oil pressure has been
corrected.
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 a few seconds before
it shuts off again.
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 box (refer to Figure 4.7).
A
Danger
The aerial platform can tip over if it becomes un-
stable. Death or serious injury will result from a tip-
over accident. 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 haz-
ard.
Retract and lower the main boom and then drive to a level
surface when the tilt alarm sounds.
Figure 4.7 – Tilt Alarm
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. An engine temperature gauge is on the
lower control panel (refer to Figure 4.8).
