SECTION 3. CHASSIS, PLATFORM, & SCISSOR ARMS
3.1 OPERATING CHARACTERISTICS
Leveling Jacks (If Equipped)
The machine may be equipped with auto-leveling jacks
with a manual adjust feature. These leveling jacks are
activated through a switch on the platform control con-
sole.
AUTO-LEVELING
1. With the machine in the stowed position, turn the
power on, start machine.
2. Press the leveling jacks button on the front of the
platform control box.
3. While squeezing the trigger switch on the joystick,
move the joystick forward to lower the leveling jacks.
4. Once the leveling jacks make contact with the
ground surface there will be up to a 5 second delay
before the actual auto-leveling begins.
NOTE: Due to varying ground conditions, there may be sev-
eral delays between machine level corrections. Be
sure ample time is allowed for all leveling adjust-
ments to be completed.
NOTE: The level adjustment of the machine may still be
improved. Refer to Manual Level Adjustment (Trim)
for more information.
5. Continue to engage the leveling jacks until the tilt
light stops blinking and is no longer lit. The platform
alarm will sound three times to indicate this is com-
plete.
NOTE: If a 2/5 flash code through the system fault light at
the platform control station, the machine is unable
to level. Reposition and try again.
6. To retract the leveling jacks, press the function but-
ton, then move the joystick backward. The platform
alarm will sound two times to indicate this is com-
plete.
NOTE: The tilt indicator shows when the machine is outside
the allowable lifting operation. When the machine
reaches a position within level of the specific market
specification, the tilt light will go out. Once the light
is out, the level adjustment of the machine may still
be improved. (Refer to Manual Level Adjustment
(Trim)).
NOTE: There is a limit switch that senses when all four cylin-
ders are fully retracted and this will light up the four
leveling jack lights in the platform control station.
The proximity sensor will not allow the jacks to be
extended or retracted when the machine is elevated.
If there is a proximity sensor failure the leveling jacks
cannot be used.
MANUAL LEVEL ADJUSTMENT (TRIM)
NOTE: There is an override feature on the leveling jack sys-
tem that allows the operator to adjust (trim) the level
of the machine to the left or right when the platform
is completely lowered. Use the following instructions
to adjust the level of the machine.
1. With the machine in the stowed position, turn the
power on, start machine.
2. Press the leveling jacks button on the front of the
platform control box.
3. To adjust (trim) the machine to the right, activate the
steer switch on the top of the joystick to the right
until the desired position is reached.
4. To adjust (trim) the machine to the left, activate the
steer switch on the top of the joystick to the left until
the desired position is reached.
NOTE: Anytime the trim function is used there is a possibil-
ity that the machine may become out-of-level. At
this time the machine will no longer lift but the
machine can be lowered.
NOTE: The machine must be in the stowed position before
the trim function is operable.
