6. If an auger header is being replaced by a rotary disc
header: Disconnect hose (A) from knife pressure
receptacle (C) on the frame. Move the hose to storage
location (B).
7. Attach the couplers to the receptacles on the windrower as
follows:
a. Connect the pressure hose female coupler to
receptacle (A).
b. Connect the return hose male coupler to
receptacle (B).
c. Connect the case drain hose coupler to receptacle (C).
d. Connect the electrical harness to receptacle (D).
IMPORTANT:
The hydraulic hoses should have enough slack to pass by
multicoupler (E) without coming into contact with it. This
will protect the hoses from rubbing against the multicoupler
and becoming damaged. The slack in the hoses can be
increased by loosening and adjusting the hose holder on the
front windrower leg before pulling the hoses backward toward the windrower.
