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 control
panel.
Use the platform lights to improve visibility while working
aloft in dimly lit areas. Do not use the platform work lights
to drive on public roadways.

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.
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 Light
An optional amber flashing light may be located on the
top of the boom near the base end (refer to Figure 4.9).
The flashing light warns personnel that the aerial platform
is in the area.
