How to Set Up the Directional
Valve Linkage
Note: Adjustment of the oscillate directional valve
linkage is only necessary when the linkage or
valve has been replaced.
1 Lower the boom to the stowed position.
2 Use a "bubble type" level to be sure the floor is
completely level.
WARNING
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 cover and the non-
steer axle covers.
5 Place a "bubble type" level across the drive
chassis non-steer end. Check to be sure the
drive chassis is completely leve.
6 Remove the ball joint retaining fastener from
the bracket.
7 To level the drive chassis, start the engine and
push up or pull down on the threaded rod until
the machine is completely level.
8 Verify that the ground and drive chassis are
completely level.

9 Adjust the ball joint until the hole lines up with
the retaining fastener hole in the bracket.
10 Install the ball joint to the axle and tighten the
jam nut.
11 Check to be sure the drive chassis is
completely level.
12 Measure the distance between the drive
chassis and the non-steer axle on both sides
(from the inside of the drive chassis).
Note: If the distance is not equal and the
adjustment to the linkage was completed with the
ground and drive chassis level, repeat steps 6
through 11 OR consult Genie Product Support.
