8042/10042 Stabil-TRAK Hydraulic Circuit
Final Positioning Mode
(S/N 9908 & Before)
CONDITIONS:
Boom raised above 40°, vehicle in forward or reverse; proximity switch relay energizes solenoids 5 and 6; solenoids 1, 2, 3, and 4 are de-
energized.
Rear axle stabilizer cylinder oil flow is dampened to the hydraulic reservoir through the .060 orifices. The rear axle will react to terrain changes,
however the reaction will be dampened by the orifices.
The operator controls speed of frame tilt of the front axle in response to the orifices rear axle.
