5. Turn the anti-restart master switch (refer to Figure
8.3) to on and pause a few seconds while the alarm
sounds to alert others that the machine is about to
start. Turn the switch to start, then release it to on.
The engine 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.

tion. Always look in the direction of movement.

riser boom, jib boom, main boom extend and plat-
form level function speeds.

leasing the foot switch will stop movement.
Driving and Steering
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 an elevated aerial plat-
form on soft, uneven, or sloping surfaces. Do not
drive the machine on grades that exceed 20 percent.
For operation on grades up to 20 percent, it is recom-
mended that the riser and main booms be fully lowered
and the jib elevated just enough to provide adequate
ground clearance. A 20 percent grade is a 61 cm (24 ″)
vertical rise in 3.05 m (10 ′) horizontal length.
Avoid driving with the platform over the front (steer) end
of the chassis. In this position the machine is difficult to
control because:
• drive and steer control movements and their result-
ing 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 plat-
form from colliding with obstacles several feet be-
yond the path of the tires.
