2.6 OSCILLATING AXLE - LOCKOUT CYLINDER TEST (IF
EQUIPPED)
NOTICE
LOCKOUT CYLINDER SYSTEM TEST MUST BE PERFORMED QUARTERLY, ANY
TIME A SYSTEM COMPONENT IS REPLACED, OR WHEN IMPROPER SYSTEM
OPERATION IS SUSPECTED.
NOTE:
Ensure platform is fully lowered prior to beginning lockout
cylinder test, and that the surface used to approach the
ramp is flat and level.
Left Side Wheel Test
1.
Place a 4 inch (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 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
approximately 7 ft (2.1 m) on the 3369LE or 9 ft (2.7 m)
on the 4069LE.
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 wheel to rest on the
ground. It may be necessary to activate DRIVE to
release cylinders.
12.
If the lockout cylinders do not function properly, have
qualified personnel correct the malfunction prior to
any further operation.
