Engaging the Bypass Function
The bypass function is performed by the multi-function
valve cartridges. The prime mover should be shut down
when opening or closing the bypass valves.
The bypass valves on both of the multi-function valves
must be opened to engaged the bypass function.

wrench on the large hex to prevent rotation of the
cartridge assembly, rotate the middle hex three
revolutions counterclockwise to open the bypass
valve.
Do not rotate more than 3-1/2 revolutions,
as additional rotation will permit external leak-
age.
2. For units with an MDC-type control, prior to moving
the vehicle or otherwise causing the motor shaft to
turn, move the control handle of the manual displace-
ment control on the pump to the maximum full
forward position. Hold the handle in this position
during bypass valve operation.
Caution
"Tow" at extremely low speeds and for short
distances only.
