Final Positioning Mode
(Fig. 9– 26)
• Rod Oil OUT
Conditions: Boom angle is above 40°, park brake OFF,
and service brake released, and travel select lever in
FORWARD (F) or REVERSE (R) position; solenoids 3
and 4 are energized.
From the rod end of the stabilizer cylinder, oil flows
through solenoid-operated valve 4, through a 0.060" ori-
fice, through another 0.060" orifice, then through sole-
noid/valve 3, then to the base end. Because of the larger
volume of oil in the base end, extra oil will be supplied
from the main system through the 100 psi (7 bar) reduc-
ing cartridge in the stabilizer block. The restrictions pro-
duce the slow movement, or “final positioning” mode.
