Advanced, auto-leveling dual oscillating axles with a
manual adjust feature. These axles are activated
through a switch on the platform control console.
AUTO-LEVELING
1. With the machine in the stowed position, turn the
power on, start machine.
2. Press the dual oscillating axles button on the front of
the platform control box.
3. While squeezing the trigger switch on the joystick,
move the joystick forward to begin leveling the
machine.
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.
4. Continue to hold the joystick forward until the level-
ing sequence ends and the platform alarm sounds
three times to indicate this is complete.
5. To realign the chassis with the rear axle, press the
function button, then move the joystick backwards.
The platform alarm will sound two times to indicate
this is complete.
NOTE: If a 2/5 flash code through the system fault light at
the platform control station while driving in the
stowed position, reattempt to realign the chassis
and the rear axle.
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)).

MANUAL LEVEL ADJUSTMENT (TRIM)
NOTE: There is an override feature on the QuikLevel
Advanced system 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 fol-
lowing 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 dual oscillating axle on the front of the plat-
form 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.

Lift

Lift up and down uses separate valves for control.

Drive

If traveling at high speed up a grade and the incline
exceeds 7° - 10° (depending on machine configuration),
the drive function will cut back to low speed. The drive
pump will shift back into high speed once the incline
decreases to 5° - 8° (depending on machine configura-
tion). There will be a two second delay before the
machine returns to high speed.
If traveling at high speed down a grade and incline
exceeds 12° - 14° (depending on machine configura-
tion), the drive function will cut back to low speed. The
drive pump will shift back into high speed once the
incline decreases to 5° - 8° (depending on machine con-
figuration). There will be a two second delay before the
machine returns to high speed.
