Boom Operation
Use the following procedure to operate the turntable,
boom, or platform functions.
1. Press the appropriate function button.
2. Squeeze and hold the interlock switch against the
joystick and push and hold the joystick in the cor-
responding direction of the colored arrow for the
selected function. Always look in the direction of
movement.
3. To stop movement release the joystick to its neutral
position or release the interlock 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 36 percent.
For operation on grades up to 36 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 36 percent grade is a 43″ (1.1 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.
Warning
Death or serious injury could result from improperly
driving or steering the aerial platform. Read and un-
derstand the information in this manual and on the
placards and decals on the machine before operating
the aerial platform on the job.
The red and yellow arrows next to the function select but-
tons on the upper control placard indicates the direction
the chassis will move when the drive or steer control is
moved toward the corresponding color.
