V. OPERATING INFORMATION

Hydraulic System Continued

Setting Each Lift Assembly

Install a 3,000 PSI pressure gauge on the inlet of the electro-hydraulic valve (fig. 5.20, item 1). With the engine running at an idle, raise each unit one at a time with the Tasseltrol® box while in “MANUAL” mode. Observe the pressure. Adjust each lift cylinder to 1000 PSI.

To increase the pressure of a given lift cylinder, turn the adjustable screw (fig. 5.20, item 2) on the raise orifice clockwise. To decrease the pressure of a given cylinder, turn the adjustable orifice screw counter-clockwise.

NOTE:

Over

After each unit has been adjusted to 1000 PSI, test the settings by turning the Tasseltrol® box to “AUTO” and activate the “ALL UP” switch (fig. 5.19) on the hydrostatic control handle (“ALL UP” dwell should be set at 20 seconds – see page 56). At this time all units should lift together.

Adjust each lower orifice as outlined on page 49.
