Connections on M1240 Windrower (Parts

1. Use a clean rag to remove dirt and moisture from the
couplers.
2. Make the following hydraulic and electrical connections
to the windrower:
a. Connect disc pressure hose (A) marked with a red
cable tie (B) with coupler (C) and torque to 205–
226 Nm (151– 167 lbf·ft)
b. Connect disc return hose (D) with coupler (E) and
torque to 205–226 Nm (151–167 lbf·ft)
c. Connect case drain hose (F) to fitting (G)
d. Connect the electrical harness to plug (H)
NOTE:
Elbow fittings on quick couplers should be set at a 30°
angle to allow hoses to pass by the multicoupler without
coming into contact with it.
NOTE:
The hydraulic hoses should have enough slack in them
to pass by multicoupler (J) without coming into contact
with it. This will keep the hoses from rubbing against the
multicoupler and protect them from becoming damaged
or worn. You can increase slack in the hoses by
loosening and adjusting the hose holder on the front
windrower leg and pulling the hoses backwards toward
the windrower.
