• Bleed the air out of the hydraulic system.
• Check the hydraulic oil level and add oil if needed. When checking hydraulic oil level,
make certain that all system cylinders are fully retracted.
• Calibrate dump light system.
• Be sure to check all clearances.
• Set/check relief pressure no higher than 4500 PSI (See procedure on next page).
Step 14: Fill reservoir and activate hydraulic flow.
• Fill reservoir to site gauge, within 3” from the top (Roughly 25 Gallons). Note: ISO 32 hy-
draulic oil is recommended.
• When connections are secure, activate hydraulic flow by opening the ball valve on the
bottom of the reservoir. This will allow oil to flow from the reservoir to the pump.
