Maintenance
A.With the bypass valve open and the engine running, slowly move the directional control in both forward and reverse (5 or 6 times).
B.With the bypass valve closed and the engine running, slowly move the directional control 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” or
•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
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.
