Q-8
Check the Oscillate Directional
Valve Linkage (if equipped)
Genie specifications require that this procedure be
performed quarterly.
Note: Perform this test only on models equipped
with an oscillating axle.
Proper axle oscillation is essential to safe machine
operation. If the oscillate directional valve linkage
is not operating correctly, the stability of the
machine is compromised and it may tip over.
1 Remove the drive chassis cover and the axle
covers from the non-steer end of the drive
chassis.
2 Locate the oscillate directional valve inside of
the non-steer axle and inspect the linkage for
the following:
•
Lock nut is tight against yoke
•
Yoke clevis pins are installed
•
Cotter pins are installed through clevis pins
•
Linkage is properly attached to directional
valve
Q-9
Visual Inspection of the Hydraulic
Oil
Genie specifications require that this procedure be
performed quarterly.
Replacement or testing of the hydraulic oil is
essential for good machine performance and
service life. Dirty oil and a clogged suction strainer
may cause the machine to perform poorly and
continued use may cause component damage.
Extremely dirty conditions may require oil changes
to be performed more often. For hydraulic oil
specifications, Refer to Specifications,
Hydraulic
Specifications
.
Note: Before replacing the hydraulic oil, the oil
may be tested by an oil distributor for specific
levels of contamination to verify that changing the
oil is necessary. Replace the oil when it fails the
test. Refer to Maintenance Procedure,
Test or
Replace the Hydraulic Oil
