How to Set Up the Oscillate
Directional Valve
Note: Adjustment of the oscillate directional valve
linkage is only necessary when the linkage or valve
has been replaced.
Note: It will take two persons to perform this
procedure.
1 Lower the boom to the stowed position.
2 Use a "bubble type" level to be sure the floor is
completely level.
Tip-over hazard. Failure to
perform this procedure on a level
floor could compromise the
stability of the machine resulting in
the machine tipping over.
3 Check the tire pressure in all four tires and add
air if needed to meet specification.
Note: The tires on some machines are foam-filled
and do not need air added to them.
4 Remove the drive chassis non-steer axle cover.
5 Loosen the lock nuts on both sides of the
adjusting rod.
6 Remove the clevis pin and clevis from the axle
mount.
7 To level the drive chassis, start the engine,
select high idle and push up or pull down on the
threaded rod until the machine is completely
level.
4 - 40
Note: It may be necessary to increase the pressure
of the oscillate relief valve temporarily to allow the
chassis to level. Do not raise the presure higher
than 1500 psi. Reset the relief valve pressure to
950 psi. Refer to 7-6, Valve Adjustments - Oscillate
Relief Valve.
8 Verify that the drive chassis is completely level.
9 Turn the adjusting rod until the clevis lines up
10 Install the clevis pin and secure with a cotter
11 Tighten the nuts on both sides of the adjusting
12 Verify that the drive chassis is completely level.
13 Measure the distance between the drive chassis
Note: The gap between the drive chassis and the
non-steer axle should be 0.150 to 0.170 inches at
the narrowest point.
Note: If the distance is not between 0.150 and
0.170 inches and the adjustment to the linkage was
completed with the ground and drive chassis level,
repeat steps 6 through 11 OR consult Genie
Service Department.
