Lubrication - Ferris 300S Series Operator's Manual

These purge procedures should be implemented any time a
hydraulic system has been opened to facilitate maintenance
or any additional oil has been added to the system.
The resulting symptoms of air in the hydraulic system may be:
• Noisy operation.
• Lack of power or drive after short term operation.
• High operation temperature and excessive expansion of
oil.
Before starting, make sure the transaxles/transmissions are
at the proper oil levels. If it is not, fill to the specifications
outlined in the Check / Fill Transmission Oil Level procedure.
Purging Air from the Hydraulic System:
1. Chock the front wheels to prevent the unit from rolling.
Raise the rear of the unit so that the unit's rear tires do
not contact the ground. Position jack stands under the
rear bumper of the unit to secure it.
2. Open the transaxle's bypass valves (see Pushing the
Unit by Hand for the location and function of the bypass
valves), start the engine, release the parking brake, and
slowly move the unit's ground speed control levers in both
forward and reverse directions (5 to 6 times), as air is
purged from the unit, the oil level will drop.
3. Stop the engine and engage the parking brake.
4. Close the transaxle's bypass valves, start the engine,
release the parking brake, and slowly move the unit's
ground speed control levers in both forward and reverse
directions (5 to 6 times), as air is purged from the unit, the
oil level will drop.
5. Stop the engine. Remove the jack stands from
underneath the unit.
6. Repeat the process detailed above but with the unit's
drive wheels on the ground. The procedure should be
performed in an area free of any objects or bystanders.
It may be necessary to repeat the process detailed above
until all the air is completely purged from the system. When
the transaxles/transmissions operate at normal noise levels
and move smoothly forward and reverse at normal speeds,
then the transaxles/transmissions are considered purged.

Lubrication

Lubricate the unit at the location shown in the following
figures as well as the lubrication points listed below.
Grease:
• Mower deck spindles (A, Figure 22).
• Rear transmission cradle pivots (A, Figure 23).
• Front caster wheel axles (A, Figure 24).
Use grease fittings when present. Disassemble parts to apply
grease to moving parts when grease fittings are not installed.
Not all greases are compatible. Your product is manufactured
using Heavy Duty Lithium Complex EP, NLGI grade 2
grease. Using non-compatible grease could damage or cause
premature parts failures.
26
Oil:
• Deck lift linkage pivots (A, Figures 25 and 26).
• Mower deck idler arm (B, Figures 25 and 26).
Generally, all moving metal parts should be oiled where
contact is made with other parts. Keep oil and grease off belts
and pulleys. Remember to wipe fittings and surfaces clean
both before and after lubrication.
