2. Footswitch (Japanese Specification Only)
For machines built to Japanese specifications, a
footswitch is provided as part of the operating sys-
tem. The footswitch must be depressed in conjunc-
tion with the red trigger switch on the joystick to
operate any function
3. Membrane Switch Panel
The function switches at the platform control station
are an integral part of a membrane switch panel,
which contains switches for drive, high drive, lift,
powered deck extension (if equipped), and posi-
trac, plus a red tilt indicator light (if equipped). The
drive, lift and powered deck extension function
switches have a small green light indicator beside
them which is illuminated when that function is
active. The function switch light indicators will flash
once or twice, then go out, when the platform emer-
gency stop switch is turned on. If the light indicators
fail to flash or if they fail to stop flashing, re-cycle the
emergency stop switch. To activate the drive, lift,
and powered deck functions, press the applicable
function switch, then activate the joystick within
three seconds to operate the function. If the joystick
is not activated within three seconds, power is
turned off to the function switch and the switch must
be pressed again. The posi-trac and high drive func-
tions are used in conjunction with the drive function.
Do not try to operate the drive, lift, and powered
deck extension functions simultaneously. If the
drive, lift, and powered deck extension functions are
selected simultaneously, no function will operate. If
this occurs, pause, then press only one of the func-
tion switches to activate the function. Refer to the fol-
lowing paragraphs for more information about the
function switches.
4. Controller (Joystick)
The joystick controls three functions: speed, direc-
tion, and powered deck extension (if equipped). The
joystick is used in conjunction with the trigger switch
and controls the drive, high drive, lift, and powered
deck extension switches to control speed and direc-
tion for the selected function. The drive, high drive
and posi-trac functions may be operated simulta-
neously, but the drive, lift, and powered deck exten-
sion functions must be operated independently of
each other. If the drive, lift, and powered deck exten-
sion functions are selected simultaneously, no func-
tion will operate. If this occurs, pause, then press
only one of the function switches to activate the
function. To operate the joystick, squeeze the red
trigger switch, then position the joystick to forward
or reverse, as desired
5. Steer Switch
The thumb-operated steer switch, located on top of
the joystick, works in conjunction with the trigger
switch and activates the steer wheels in the direction
the switch is moved (left or right).
6. Drive Switch
The drive switch, when used in conjunction with the
joystick, provides for driving the machine in forward
or reverse. Drive is activated by pressing the drive
switch, in conjunction with the trigger switch, and
moving the joystick forward (forward) or backward
(reverse). Drive speed is determined by the distance
the joystick is moved forward or backward.
Increased drive speed is possible when the high
drive speed switch is pressed either simultaneously
with the drive switch or while operating the drive
function. The drive switch is part of the enable cir-
cuit, which provides power to the joystick and the
drive function for 3 seconds when the drive switch is
pressed. If the joystick is not activated within 3 sec-
onds, the drive switch must be pressed again before
activating the joystick. When the joystick is returned
to the center off position, the operator has 3 sec-
onds to re-activate the joystick or select another
function before power is removed by the enable cir-
cuit. In addition, the posi-trac switch can be
engaged while operating the drive function to give a
more evenly distributed oil flow to each drive motor.
Do not try to operate the drive, lift, and powered
deck extension functions simultaneously. If the
drive, lift, and powered deck extension functions are
selected simultaneously, no function will operate. If
this occurs, pause, then press only one of the func-
tion switches to activate the function
NOTE: The machine is equipped with a Pothole Protection
System which lowers automatically when the plat-
form is raised. If the Pothole Protection System does
not fully lower, the DRIVE function is cut out until the
platform is completely lowered.
