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.
Figure 5.7: Ground Speed Lever (GSL)
1. Start the engine.
2. Use HEADER TILT switches (A) on the ground speed
lever (GSL) to set the center-link to the mid-range position.
3. Using HEADER DOWN switch (B), lower the header fully.
The header lift cylinders will fully retract.
4. Ensure the header is level with the ground with zero tilt.
5. Shut down the engine, and remove the key from the ignition.
6. Grasp one end of the header and lift it up. The lifting force should be 335–380 N (75–85 lbf) and should be the same at
both ends.
7. Restart the engine, and adjust the float as needed. For instructions on adjusting the float, refer to 5.5.2 Setting Float –
M1 Series Windrowers, page 100.
NOTE:
Increasing the float makes the header feel lighter.
