Sequence Of Operation - Line-Out - Allied Systems W8L Service Manual

Sequence of Operation - LINE- OUT
LINE-OUT (reverse) operation is achieved by pushing
the control lever forward from the BRAKE-ON position,
which simultaneously closes the bypass valve and
opens the accumulator valve. Oil fl ow from the pump
and accumulator increases pressure. Brake pressure
increases. The brake and reverse clutch proportional
valves open according to the control module program.
Figure 3-8 Hydraulic System, Electronic Controls - LINE-OUT (Reverse)
Modulated pressure to the clutch and brake is supplied
during inching (slight movement of the control lever from
the BRAKE-ON position). Full pressure is applied to the
clutch when the control lever is in full LINE-OUT position.
Brake pressure is limited to just above brake release
pressure for faster response.
