Controls
CAUTION
Risk of personal injury or equipment damage if
repositioning boom with platform removed. Use
base controls with auxiliary power (engine off) to
reposition safely.
If boom repositioning is necessary with the platform
removed, reconnect the two cable harnesses and the
jib (as equipped) and platform rotate harness to the
platform control box.
IMPORTANT
If boom repositioning is necessary during this
procedure, select emergency power position from
start–function enable–emergency power switch,
then activate desired boom function.
When operating on auxiliary power, do not
operate more than one function at a time to avoid
overloading the 12-volt auxiliary pump motor.
IMPORTANT
Be aware that the short length of control cables
connected to the platform control box limits boom
movement.
Procedure:
1.
Connect the jib and platform rotate harness as
