few seconds while the alarm sounds to alert others
that the machine is about to start. Wait ten seconds
for the engine to preheat, if required.

gine will not start if the switch is left in the on position
for 30 seconds or longer before turning it to start. The
switch must be turned back to off before the engine
will start.

Always look in the direction of movement.
3. To stop movement release the control to its neutral
position or release the foot switch.

Driving and Steering

Danger
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury will result from a tip-over
accident. Do not drive an elevated aerial platform on
soft, uneven, or sloping surfaces. Do not drive the
machine on grades that exceed 45 percent.
For operation on grades up to 45 percent, it is recom-
mended that the main boom be near horizontal and the
jib be elevated just enough to provide adequate ground
clearance.
A 45 percent grade is a 4.5' (1.37 m) vertical rise in 10'
(3.05 m) horizontal length.
Avoid driving with the platform over the front end of the
chassis. In this position the machine is difficult to control
because:
• Drive and steer control movements and their resulting
machine movements are reversed.
• When driving fast, sudden turns or stops produce
more severe reactions to platform occupants.
• More turning space is required to prevent the platform
from colliding with obstacles several feet beyond the
path of the tires.
