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
gauge panel above the lower controls (refer to Figure
4.10).
Figure 4.10 – Engine Gauge Panel
High Engine Temperature Alarm
If the coolant in a Cummins engine exceeds the engine
operating temperature an alarm will sound and the en-
gine will shut off.
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 opera-
tion. 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 re-
started with low oil pressure, but it will only run a few
seconds before it shuts off again.
Horn
The horn may be used to warn personnel on the ground.
The horn button is on the right side of the upper control
box. The horn is operational when the emergency stop
button and the start switches are both on, at the lower
and 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 per-
sonnel in the work area to stand clear.
Flashing Lights
Optional red or amber flashing lights may be located on
each side of the machine, on the top of the cowling (re-
fer to Figure 4.11). The flashing lights warns personnel
that the aerial platform is in the area.
Figure 4.11 – Flashing Light
The light flashes at about one flash per second when
the engine is running.
Driving Lights
Optional headlights and blinking tail lights may be in-
stalled on the machine. The headlights are located on
the top of the front cowling. The tail lights are mounted
on the sides of the rear cowling.
Driving lights help improve visibility while driving the
aerial platform and help others see it too. Driving lights
are not for driving on public roadways.
Platform Work Lights
Optional platform work lights may be located on the top
rail of the platform, one on each side of the upper con-
trol panel.
Use the platform lights to improve visibility while work-
ing aloft in dimly lit areas. Do not use the platform work
lights to drive on public roadways.
