Hydraulic System
Maintenance
Check Auxiliary Hydraulic Oil
Level
Service Interval: Every 50 hours
1. Lower the tines to the ground.
2. Stop engine and wait for all moving parts to stop, and
remove key. Engage parking brake.
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 107°C (225°F).
The Cold level shows the level of the oil when it is at
24°C (75°F). Fill to the appropriate level depending
upon the temperature of the oil. For example: If the
oil is about 65°C (150°F), fill to halfway between the
Hot and Cold levels. If the oil is at room temperature
(about 24°C (75°F)), fill only to the Cold level.
