6.
Overload Indicator (If Equipped) - Indicates the platform
has been overloaded. An audible alarm will also signal
when the plaform is overloaded.
NOTE:
If the Overload Indicator is illuminated, all functions will be
prevented from the platform controls. Using the ground
controls or manual descent, fully lower the machine and
reduce the weight in the platform so as to not exceed the
rated workload indicated on the capacity decal.
7.
Controller and Steer Switch
a.
Control Handle - The control handle controls five
functions: drive, lift, power deck, leveling jacks and
steer. The drive, lift, power deck or leveling jack
function switch must be selected and the red trigger
switch must be depressed and held during control-
ler movement, prior to moving the control handle.
After selecting the drive function, moving the control
handle forward will drive the machine forward and
moving the control handle backwards will drive the
machine backward. After selecting the lift function,
moving the control handle forward will lift the plat-
form up and moving the control handle backward
will lower the platform. After selecting a power deck
function, moving the control handle forward will
extend the power deck extension and moving the
control handle backward will retract the power deck
extension. After selecting the leveling jack function,
moving the control handle forward will extend all
four leveling jacks. moving the hand controller
backward will retract the leveling jacks. The speed
on all selected functions, (except leveling jacks), is
proportionally controlled by the distance of travel of
the hand controller. The thumb-operated steer
switch on top of the hand controller activates the
steer wheels in the direction activated (right or left).
b.
Steer Switch/Auto Leveling Trim Adjust - The steer
switch/auto leveling trim adjust is located at the top
of the control handle. Selecting the drive function
and depressing the switch to the right will steer the
wheels to the right. Depressing the switch to the left
will steer the wheels to the left. When auto leveling
is selected this switch is used to manually adjust
(trim) the leveling of the machine to the left or right.
Refer to Section 4.3 for leveling jack operating pro-
cedures.
8.
Lift Select - When selected, the lift function will be active
for 5 seconds. Moving the control handle in the forward
or reverse direction within the 5 seconds will cause lift
motion to occur at a speed determined by the range
selected by the Low/High switch and the distance the
controller is moved from center. The proportional control
does not effect the lift down function.
