SECTION 3 - MACHINE CONTROLS AND INDICATORS
8. Drive/Steer.
Provides for driving either forward or backward. Push
forward to drive forward, pull back to drive in reverse.
Steering is controlled by a thumb-activated rocker
switch on top of the joystick.
NOTE: Both drive and steer functions work in the opposite
direction when the boom is positioned over front of
the chassis.
9. Main Telescope Control.
Allows extension and retraction of the main boom when
positioned to in or out.
10. Articulating Jib Lift. (460SJ Only)
Push level, toggle switch forward to lift up, pull back to
lift down.
11. Platform Rotate.
Allows the operator to rotate the basket to the left or
right when positioned to the desired direction.
3-14
DO NOT OPERATE MACHINE IF DRIVE SPEED/TORQUE SELECT OR
FUNCTION SPEED SWITCHES OPERATE WHEN BOOM IS ABOVE HORI-
ZONTAL.
12. Function Speed.
Provides variable speed control of all boom functions
grouped to the right of the knob. For smoothest opera-
tion of these functions, use two hands: rotate the knob
counterclockwise to the slowest position, select the
function switch, and while holding the switch on, rotate
the knob to the desired speed. To achieve a smooth
stop, rotate the knob ccw to a slow speed prior to let-
ting go of the function switch.
Rotating the knob fully counterclockwise until a click is
heard puts all controls, including drive, main lift, and
swing into creep speed. This slow speed is used for
fine positioning of the platform when close to obsta-
cles. A snail symbol is used to indicate "creep" speed
and is shown at the Function Speed knob as well as
near the proportional controllers to act as a reminder.
