Hydraulic Unit Overview

Flush and Startup procedure (10HP and 20HP)
1) Disconnect all power to the Hydraulic Unit.
2) Fill the Hydraulic Reservoir with any of the approved fluids and fill case drain if applicable on the
10HP and 20HP units.
3) Disconnect all devices such as hydraulic motor hoses and connect the lines together to by-pass
the motor.
4) Connect all feed lines and disconnect all return lines at the Hydraulic Unit and place in a bucket for
draining.
5) Close all flow controls and verify proper voltage and wiring.
6) Bump the Motor Starter to verify proper motor rotation.
7) Start the Hydraulic Unit and open each flow control until the fluid that comes out of the return
hoses is clean.
8) Reconnect all motors and return lines.
9) Start the Hydraulic Unit and check for proper Conveyor movement and correct rotation of all side-
wheels.
10) Adjust speeds for each component according to the individual component manuals.
Maintenance
• Check fluid level in hydraulic reservoir daily prior to startup.
• Check the oil temperature monthly at the end of a busy day. The temperature should always be
below 130º. The thermostat is part of the leveling site-gauge.
• Change the return oil filter annually or if the return pressure gauge goes into the red zone (which
ever comes first).
• Change the ISO-32 Hydraulic Oil every 3 years or if the oil appears dirty. A leak detector die may
be added to for quick leak detection.
• If a water glycol oil is used, check titration monthly. Change the oil and clean the reservoir based
on your oil manufacturers recommendations.
Startup procedure (5HP)
1) Follow the steps in both above sequences.
2) Open SNUBBER VALVE.
3) Start the Hydraulic Unit
4) Close the FLOW CONTROL
5) Verify system pressure at 900PSI. If not at 900PSI, adjust system pressure RELIEF VALVE to
obtain 900PSI.
6) Open FLOW CONTROL to desired equipment speed
7) Close SNUBBER VALVE
