How to Set Up the Oscillate Directional Valve
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.
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 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 level.
6 Remove the heim joint retaining fastener from
the axle.
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.
