Checking Tire Pressures; Check/Add Gearbox Oil Level; Changing The Gearbox Oil; Lubrication - Ferris IS600 Series Operator's Manual

2. Fill the new filter with oil. Lubricate the new filter seal with
a few drops of oil.
3. Remove the oil filter and quickly thread the new filter onto
the filter base until the gasket makes contact, then tighten
3/4 of a turn more.
4. Raise the seat plate to gain access to the hydraulic oil
tank.
5. Fill the hydraulic oil reservoir with fresh oil and
replace any oil lost during filter change.
6. Raise the rear of the unit and secure with jack stands.
Chock the front wheels to prevent the unit from rolling.
Run the unit for several minutes to purge any air from the
hydraulic system and check the hydraulic oil level.
NOTICE Use caution after changing the filter. Air in the
hydraulic system may affect the responsiveness of the
control levers. Repeat step #6 until air is completely purged
from the system.

Checking Tire Pressures

Tire pressure should be checked periodically, and maintained
at the levels shown in the Specifications chart. Note that
these pressures may differ slightly from the "Max Inflation"
stamped on the side-wall of the tires. The pressures shown
provide proper traction and extend tire life.

Check/Add Gearbox Oil Level

This unit is equipped with a sealed gearbox (A, Figure
42) that needs its oil checked periodically. Refer to the
Maintenance Schedule for the specific intervals for checking
the gearbox oil level.
42
To check the gearbox oil level:
1. The gearbox's fill plug (B) is located on the front of the
gearbox. Remove the fill plug from the gearbox.
2. Once the fill plug is removed, oil should seep out of the
fill plug hole. If no oil drains out, fill with Amsoil® SAE
75W-140 weight gear oil (or equivalent) until oil starts to
seep from the hole and then replace the fill plug.

Changing the Gearbox Oil

Change interval: Every 250 Hours (Initial Gearbox Oil
Change after first 50 hours of operation).
1. Park the unit on a flat, level surface such as a concrete
floor. Disengage the PTO, engage the parking brake, turn
the ignition switch to OFF, and remove the ignition key.
2. There is a port on the right side lower support bracket (C,
Figure 42) that allows access to the drain plug (D).
3. Position the lower gearbox pulley so that when the oil
is drained from the gearbox it can drain into a container
without spilling on the pulleys and/or belts.
4. Remove the oil drain plug and completely drain the
gearbox oil into the container.
5. Replace the drain plug.
6. Remove the oil fill plug (B) and fill with Amsoil® SAE
75W-140 weight gear oil (or equivalent) until oil starts to
seep from the fill hole. Replace the oil fill plug.
7. Using a parts solvent, thoroughly clean any excess oil
that may have spilled on the pulley, pulley grooves, and/
or belts.

Lubrication

Lubricate the unit at the location shown in Figures 43, 44, 45
and as well as the following lubrication points.
Grease:
• front caster wheel axles and yokes.
• deck lift pivot blocks.
• deck lift linkages.
• mower deck spindles.
Use grease fittings when present. Disassemble parts to apply
grease to moving parts when grease fittings are not installed.
Not all greases are compatible. Red grease (p/n 5022285)
is recommended, automotive-type, high-temperature, lithium
grease may be used when this is not available.
Oil:
• control handle pivots.
• seat plate pivots.
• deck lift pivots.
• discharge chute hinge.
• parking brake lever shafts.
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 fitting and surfaces clean
both before and after lubrication
