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. FIG 5.19 After each unit has been adjusted to 1000 PSI, test the set-
