Detaching an R1 Series header from an M1 Series windrower requires removing the electrical and hydraulic connections,
detaching the header supports, and releasing the center link.
DANGER
To prevent bodily injury or death from the unexpected startup of the machine, always stop the engine and remove the
key from the ignition before leaving the operator's seat for any reason.
DANGER
Ensure that all bystanders have cleared the area.
1. Start the engine.
2. Press switch (A) to raise the header to its maximum height.
3. Shut down the engine, and remove the key from
the ignition.
4. Engage the safety props on both lift cylinders as follows:
a. Pull lever (A) toward you to release it, and then rotate
it toward the header to lower the safety prop onto the
cylinder.
