and level.
Left Side Wheel Test
1.
Place a 4 in (10.16 cm) high block with ascension ramp in front
of left wheel of the oscillating axle.
2.
From platform control station, select LOW drive speed.
3.
Set the DRIVE control switch into position and carefully drive
the machine up ascension ramp until left oscillating axle wheel
is on top of block.
4.
Verify the axle oscillates to maintain contact with the ground/
ramp. (All four wheels on the ground.)
5.
Raise machine platform above stowed position to drive cutout
height, approximately 6 to 9 ft (2 to 3 m) for the 330LRT and
430LRT.
6.
Carefully drive the machine back off the block and ramp.
7.
Have an assistant check to see that the left oscillating axle
wheel that was on the block is in position on the ground. The
axle should oscillate so that all four wheels maintain contact
with the ground.
8.
In the current position (platform raised and all four tires on flat
and level surface), carefully drive machine up the ramp block
again.
9.
Have an assistant check to verify that the axle did not oscillate
and remained locked (one wheel is off of the ground).
10.
Carefully drive the machine back off the block and ramp.
11.
Lower the machine platform; the lockout cylinder should then
release and allow the axle to oscillate. It may be necessary to
activate DRIVE to release cylinders.

If the lockout cylinders do not function properly, have qualified
personnel correct the malfunction prior to any further opera
