7. Start engine and allow hydraulic system to warm up. Operate controls
gradually until you fully extend and retract each cylinder, including
steering cylinders. This procedure removes air from the system.

the engine. Recheck oil level and add oil as required.
9. Loosen and remove hose (Item 3) from reservoir filler fitting (Item 4).
Install hex cap (Item 1) and torque to 70 ft-lbs.
CAUTION: Do not fill reservoir through breather opening. The hydraulic
system can become contaminated.
Oil must be filtered through the return filter to ensure purity.
Contamination, even small amounts, can permanently damage hydraulic
system components and void the warranty.
