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
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 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.

inflated.
Note:
Do Not add any type of tire liner or foam
fill material to the tires. Excessive loads created by
foam filled tires may cause failures to the hydro drive
