Horn
The horn may be used to warn personnel on the ground.
The horn button is to the right of the emergency stop
button on the upper control panel (refer to Figure 4.8).
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. The flashing light warns person-
nel that the aerial platform is in the area.
The light flashes at about one flash per second when the
engine is running.
Driving Lights
Optional headlights and blinking tail lights may be installed
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 (refer to Figure 4.9), one on each side
of the upper control panel.
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 ex-
ceeds 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 4.7).

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 (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.
