PROBLEM POSSIBLE CAUSE CORRECTION
9. External hydraulic uid
leakage.

Control valve O-rings defec-
tive.

Replace defective O-rings.

Control valve spool or body
damaged or worn.

Replace control valve.

Cylinder rod packing set leak-
age.

Check cylinders for leakage.

Repair as needed.
10. Hydraulic pump capacity
inadequate.

Cold hydraulic uid.

Allow hydraulic uid to warm up to operating temperature.

Engine R.P.M. too slow.

Increase engine R.P.M.

Low hydraulic uid supply.

Refer to Tractor Operator's Manual for service recommenda-
tions.

Hydraulic hose restriction.

Check for evidence of restriction in hydraulic hoses.

Hydraulic pump defective.

Refer to Tractor Operator's manual for recommended ser-
vice procedures. Replace hydraulic pump if determined to
be defective.
11. Lift cylinder rod bend when
lift cylinders extended.

Excessive shock load on lift
cylinders during transport.

Replace defective parts. Review and observe proper and
safe operational practices.
12. Bucket cutting edge wear is
uneven side to side.

Bucket is not level to ground.

Check rear tire ination and adjust to level bucket to ground.
13. Bucket cutting edge wear
rate is excessive. (Wear rate
is even across full width of
bucket).
Note : Extensive use of bucket
on concrete or asphalt surfaces
will accelerate wear rate of
bucket cutting edge.

Incorrect operational prac-
tices.
Excessive down pressure
placed on bucket when being
used on hard abrasive sur-
faces.

Refer to operation-scraping section for correct operating pro-
cedures.
Utilize oat position.

