NOTICE
Prevent machine damage.
Failure to perform flushing procedure after
a pump, motor or hose failure will result
in a repeat failure and will void machine
warranty.
Either the conveyor loop or traction drive loop can be
flushed, depending on which loop has failed. If there is
a concern that both loops have debris, refer to Flushing
Conveyor And Traction Drive Systems in section 6.4.3.

NOTICE
Prevent machine damage.
Do not pour hydraulic oil directly into
closed loop circuit hoses or a failure will
occur.
In following detail, major steps are mentioned as "Step
#" for dual side machine or as "Step #A" for single
sided machine where applicable. These steps refer to
the schematic description with same headings.

connect to each other using a 3/4 MJIC x 3/4 MJIC
adapter. This is shown as step 2 (for dual side) and
2A (for single sided).
Start the engine and slowly increase conveyor flow

until filter's "visual service indicator" is positioned
in center of the window. If pump goes over relief,
the flow is going against check valve. Stop the
flow, then reverse conveyor direction or hoses.
