NANCE (72620 & 74824)
Service and Maintenance
CAUTION
Hydraulic systems contain fluid under high pressure.
Never check for leaks with your hands. Relieve pres-
sure before disconnecting any hydraulic lines.
CAUTION
Before servicing or repairing any of the hydrostatic feed
components (pump, motor, and/or relief valve), contact
your dealer or factory service department. Warranty on
these items may be void without prior authorization.
The hydrostatic pump normally does not require regular
fluid changes. The system filter should be changed at 250
hour or annual intervals. The fluid and filter should be
changed and system cleaned if the fluid becomes
contaminated with foreign matter (water, dirt, grease, etc.)
or if the fluid has been subjected to temperature levels
greater than the maximum recommended.
There is a greaseable bearing on each side of the main
jack shaft on the main hydraulic feed housing. Grease
periodically.
