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 dura-
tion of travel. Drive speed is determined by the dis-
tance 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
traction is a problem. Do not try to operate the drive,
lift, and powered deck extension functions simulta-
neously. 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 function switches to activate the function.
IMPORTANT
WHEN TRAVELING A GRADE, MAXIMUM TRACTION IS OBTAINED
BY TRAVELING IN REVERSE. REVERSE TRAVEL SHOULD BE
USED WHEN LOADING ON A TRUCK OR WHEN ADEQUATE
TRACTION IS NOT ACHIEVED BY TRAVELING FORWARD.
NOTE: If the machine is equipped with the optional powered
deck extension, the DRIVE function is cut out when
the deck is extended with the platform raised above
the stowed position.
As an option, Models 2033E3 and 2646E3 may be
equipped for 1,000 lb. (455 kg) platform capacity.
