215575 93 Revision B
3.12.4 Adjusting Header Float
The header float setting is factory-configured but can be adjusted for various harvest conditions.
WARNING
To avoid bodily injury or death from unexpected startup of machine, always stop the engine and remove the key from
the ignition before leaving the operator’s seat for any reason.
1. Attach the header to the combine feeder house and ensure that it is latched securely. It is not necessary to attach the
driveline or hydraulic connections. For instructions, refer to the relevant combine attaching procedure in: 3.10 Header
Attachment and Detachment, page 38
2. Lower the combine feeder house so that the front draper deck rotates upwards to the full floated-up position. The
header frame will be close to the ground and the coil spring will be fully collapsed.
NOTE:
The tension of the coil spring is factory-set to the second hole from the bottom on the float anchor.
3. Shut down the combine and remove the key from the ignition.
Figure 3.149: Left Endshield
4. Open left endshield (A). For instructions, refer to 3.3.1
Opening Left Endshield, page 25.
NOTE:
The right spring float assembly can be removed or adjusted
without removing the right endshield. For improved
accessibility, however, remove four M12 carriage bolts and
hex flange nuts from the endshield support (not shown)
and remove the right endshield.

5. Ensure that all spring tension has been released from spring
float assembly (A). Remove cotter pin (B), clevis pin (C), and
three flat washers (D).
NOTE:
When the spring tension is fully released, the spring coils
should be fully collapsed and the spring float assembly
should rock from side to side when moved by hand. If
pressure on the clevis pin is still present, raise or lower
the header slightly.
