Maintenance
in both forward and reverse directions (5 to
6 times). Check the oil level, and add oil as
required after stopping the engine.
C. It may be necessary to repeat steps A and B
until all the air is completely purged from
the system. When the transaxle operates at
normal noise levels and moves smoothly
forward and reverse at normal speeds, then
the transaxle is considered purged.
Note: Do Not change the hydraulic system oil
(except for what can be drained when changing filter),
unless it is felt the oil has been contaminated or been
extremely hot.
Changing oil unnecessarily could damage hydraulic
system by introducing contaminants into the system.
Check Spark Arrester
(if equipped)
Service Interval: Every 50 hours
WARNING
Hot exhaust system components may ignite
gasoline vapors even after the engine is stopped.
Hot particles exhausted during engine operation
may ignite flammable materials. Fire may result
in personal injury or property damage.
Do Not refuel or run engine unless spark arrester
is installed.
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Wait for muffler to cool.
3. If any breaks in the screen or welds are observed,
replace arrester.
4. If plugging of the screen is observed, remove
arrester and shake loose particles out of the
arrester and clean screen with a wire brush (soak
in solvent if necessary). Reinstall arrester on
exhaust outlet.

Thread Locking Adhesives

Thread locking adhesives such as "Loctite 242",
"Loctite 243", or "Fel-Pro, Pro-Lock Nut Type" are
used on the following fasteners:
• ROPS spring pin housing.
• Sheave and clutch retaining bolt in the end of
engine crankshaft.
• Hydro cross member mounting bolts
Thread locking adhesives are required for some
hardware on engines — see the Engine manual.

Copper-Based Anti-seize

Copper-based anti-seize is used in the following
location:
On threads of Blade Bolts. See Check Mower
Blades section.

Dielectric Grease

Dielectric grease is used on all blade type electrical
connections to prevent corrosion and loss of contact.
Dielectric grease should not be applied to sealed
connectors.
