close. Remove and retain the hose for future use.
e) Replace the oil filter as per Engine Owner's Manual. 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
2/3 to 3/4 turn.

5.1.8 Check hydraulic oil level.
Service Interval: 40 hr.
a) Stop engine and wait for all moving parts to stop.
b) 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
Mobil 1 15W-50 synthetic motor 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 a 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°), fill to halfway between the "HOT"
and "COLD" levels. If the oil is at room temperature (about 75°F (24°C)), fill
only to the "COLD" level.
