4.5 PLATFORM EXTENSION
Manual Platform Extension
The machine is equipped with a mechanically extendible
deck, which adds 0.9 meters to the front of the platform,
giving the operator better access to worksites. To extend
the deck, squeeze the release lever on the handle on the
right side of the platform to release the lock pin, then use
the handle and handrail to push the extendible deck out.
To retract the deck, squeeze the release lever to release
the lock pin and use the handle and handrail to pull and
retract the deck. Be sure the lock pin is locked in place
after the deck is retracted. Maximum capacity of the deck
extension is 113 kg - 1 person.
IF THE MACHINE IS EQUIPPED WITH THE OPTIONAL PIPE
R A C K S , T H E P L AT F O R M E X T E N S I O N M U S T B E I N T H E
RETRACTED POSITION WHEN THE PIPE RACKS ARE LOADED.
FAILURE TO RETRACT THE PLATFORM EXTENSION COULD
RESULT IN DAMAGE TO THE PLATFORM EXTENSION.
IF THE MACHINE IS EQUIPPED WITH A POWERED DECK EXTEN-
SION AND THE OPTIONAL FOLD-DOWN RAILS, THE RAILS MUST
BE IN THE UPRIGHT POSITION BEFORE RETRACTING THE
POWER DECK EXTENSION
4.6 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 posi-
tion. To return the wheels to the straightened position, the
switch must be activated in the opposite direction until the
wheels are centered.

SMOOTH, FIRM AND LEVEL SURFACE FREE OF OBSTRUCTIONS
AND HOLES.
TO AVOID LOSS OF TRAVEL CONTROL OR UPSET ON GRADES
AND SIDESLOPES, DO NOT DRIVE MACHINE ON GRADES OR
S I D E S L O P E S E X C E E D I N G T H O S E S P E C I F I E D F O R T H E
MACHINE.
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 1.8 METERS OF
AN OBSTRUCTION.
SELECTION OF MULTIPLE FUNCTIONS WHEN TRAVELING UP A
GRADE CAN CAUSE AN OVERCURRENT SHUTDOWN TO OCCUR.
IF THIS SHOULD HAPPEN, LET THE CONTROL HANDLE RETURN
TO NEUTRAL, THEN PAUSE FOR 3-5 SECONDS TO ALLOW THE
SYSTEM TO RESET BEFORE RE-SELECTING A FUNCTION. TO
GO BACK DOWN THE GRADE, IF TRAVELING FORWARD UP THE
GRADE, BUMP THE CONTROL HANDLE FORWARD SLIGHTLY TO
ENSURE THE BRAKES ARE RELEASED BEFORE DESCENDING
THE GRADE.
WHEN TRAVELING ON A GRADE, MAXIMUM TRACTION IS
OBTAINED BY TRAVELING IN REVERSE. ALWAYS USE REVERSE
TRAVEL WITH LOW SPEED AND POSI-TRAC ENGAGED WHEN
LOADING ON A TRUCK OR WHEN ADEQUATE TRACTION IS NOT
OBTAINED TRAVELING FORWARD.
NOTE: The machine is equipped with a Pothole Protection
System which lowers automatically when the plat-
form is raised. If the pothole protection does not fully
lower, the drive function is cut out until the platform is
completely lowered.
Traveling Forward
1. Place power selector switch at ground control sta-
tion to platform.
2. Position emergency stop switch at Platform Control
Station to on position.
3. Press drive switch, in conjunction with the trigger
switch, and move joystick forward and hold for
duration of travel. Drive speed is determined by the
distance the joystick is moved from the center off
position. The drive switch is part of the enable cir-
cuit, which supplies power to the drive switch and
the joystick for 3 seconds after the drive switch is
pressed. If the joystick is not activated within 3 sec-
onds after the drive switch is pressed, power is
removed from the switch and joystick and the switch
must be pressed again before activating the joystick.
When the joystick is returned to the center off posi-
tion, the operator has 3 seconds to re-activate the
joystick or select another function before power is
removed by the enable circuit. For additional drive
speed, press the high drive speed switch simultane-
ously when depressing the drive switch or while
operating in the drive forward mode. The posi-trac
switch can also be used in conjunction with drive to
evenly divide the oil flow to each drive motor when
