Setting Each Lift Assembly
Install a 3000 PSI pressure gauge on the inlet of the elec-
tro-hydraulic valve (fig. 4.10, 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. 4.10, item 2) on the raise orifice clock-
wise. To decrease the pressure of a given cylinder, turn the
adjustable orifice screw counter-clockwise.
After each unit has been adjusted to 1000 PSI, test the set-
tings by turning the Tasseltrol
®
box to “AUTO” and activate the
“ALL UP” switch (fig. 4.9) on the hydrostatic control handle
(“ALL UP” dwell should be set at 20 seconds – see page 34).
At this time all units should lift together.
Adjust each lower orifice as outlined on page 26.
NOTE:
Over adjustment of raise
orifice can cause excessive
working pressure.
