4.6 MECHANICAL PLATFORM EXTENSION
(OPTIONAL)
The machine may be equipped with a mechanically
extendable deck, adding 4 ft. (1.2 meters) to the front of
the platform, giving the operator better access to work-
sites. The deck extension is manually controlled by a pair
of handles connected to latching rods in the platform rail-
ing. With the handles in the down (vertical) position, the
latching rods are positioned into a pair of holes in the plat-
form deck, securing the extendable portion of the deck in
either the extended or retracted position. With the handles
in the up (horizontal) position, the latching rods are posi-
tioned above the platform deck, allowing the extendable
deck to be extended or retracted.
4.7 STEERING
To steer the machine, the thumb operated steer control
switch on the controller handle is positioned to the right
for traveling right, or to the left for traveling left.
When released, the switch will return to the center-off
position and the wheels will remain in the previously
selected position. To return the wheels to the straightened
position, the switch must be activated in the opposite
direction until the wheels are centered.
4.8 TRAVELING - (DRIVING)
ALWAYS RAISE LEVELING JACKS, IF EQUIPPED, BEFORE TRAV-
ELING TO AVOID INJURY TO PERSONNEL OR DAMAGE TO
MACHINE.
IF MACHINE BECOMES STUCK DURING TRAVEL, DO NOT
“ROCK” MACHINE IN AN ATTEMPT TO REGAIN TRACTION, AS
DAMAGE TO DRIVE HUBS MAY RESULT.
D O N O T D R I V E WI TH P LATF OR M R A I S E D E X C E P T ON A
SMOOTH, FIRM, AND LEVEL SURFACE FREE OF OBSTRUCTIONS
AND HOLES.
TO AVOID LOSS OF CONTROL OR UPSET ON GRADES AND
SIDESLOPES, DO NOT DRIVE MACHINE ON GRADES OR SIDES-
LOPES EXCEEDING THOSE SPECIFIED ON CAUTION PLACARD
AT PLATFORM. TRAVEL GRADES AND SIDESLOPES WITH PLAT-
FORM COMPLETELY LOWERED.
TRAVEL GRADES IN “LOW” DRIVE SPEED ONLY. USE EXTREME
CAUTION WHEN DRIVING IN REVERSE AND AT ALL TIMES WHEN
DRIVING WITH PLATFORM ELEVATED AND ESPECIALLY WHEN
DRIVING WITH ANY PART OF MACHINE WITHIN 6 FT (2 M) OF AN
OBSTRUCTION.
HIGH DRIVE SPEED IS CUT OUT WHEN PLATFORM IS RAISED
ABOVE STOWED POSITION. IF LIMIT SWITCH MALFUNCTIONS,
SHUT DOWN MACHINE AND HAVE AUTHORIZED SERVICE PER-
SONNEL REPAIR OR REPLACE LIMIT SWITCH PRIOR TO RESUM-
ING OPERATION.
MACHINE MAY BE EQUIPPED WITH A 3 DEGREE TILT SWITCH
THAT ILLUMINATES A LIGHT ON THE PLATFORM CONTROL
CONSOLE AND SOUNDS AN AUDIBLE ALARM WHEN THE
MACHINE IS ON A SEVERE SLOPE (OVER 3 DEGREES) WITH THE
PLATFORM RAISED.
Traveling Forward
1. Position main power switch to on (or platform, if
applicable) and position power on switch to on. If
machine has been shut down, start engine and
allow warm-up period before beginning any lifting.
2. Position pump and engine control switches to
desired positions (high or low) and position drive
control switch to desired position (torque or speed).
3. Position controller to forward, squeeze red trigger
switch on front of controller, and hold controller in
position for duration of travel. The red trigger switch
must be held for the duration of travel. Drive speed
is determined by the distance the controller is
moved from the center off position.
Traveling in Reverse
1. Position main power switch to desired position and
position power on switch to on. If machine has been
shut down, start engine and allow warm-up period
before beginning any lifting.
2. Position pump and engine control switches to
desired positions (high or low) and position drive
control switch to desired position (torque or speed).
3. Position controller to forward, squeeze red trigger
switch on front of controller, and hold controller in
position for duration of travel. The red trigger switch
must be held for the duration of travel. Drive speed
is determined by the distance the controller is
moved from the center off position.
