rubber dust ejector is pointing downward and
secure with retaining clips.

4. Replace the oil filter every other oil change. Clean
around oil filter and unscrew filter to remove.
Before reinstalling new filter, apply a thin coating
of oil on the surface of the rubber seal. Turn
filter clockwise until rubber seal contacts the filter
adapter then tighten filter an additional 1/2 to
3/4 turn.

Check Hydraulic Oil Level
Service Interval: Every 40 hours
1. Stop engine and wait for all moving parts to stop.
Engage parking brake.
2. Clean area around hydraulic reservoir cap and
remove cap. Oil level should be to the top of the
baffle inside the tank. If not, add oil. Use only
Exmark Premium Hydro oil. Replace hydraulic
reservoir cap and tighten until snug. Do Not
overtighten.
Note: The baffle is labeled “HOT” and
“COLD”. The oil level varies with the
temperature of the oil. The “HOT” level shows
the level of oil when it is at 225°F (107°C). The
“COLD” level shows the level of the oil when
it is at 75°F (24°C). Fill to the appropriate level
depending upon the temperature of the oil. For
example: If the oil is about 150°F (65°C), fill to
halfway between the “HOT” and “COLD” levels.
