3. 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 AW-32
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.
If the oil is at room temperature (about 75°F
(24°C)), fill only to the “COLD” level.
