1. Start the engine.
2. Use the HEADER TILT switches (A) on the ground speed
lever (GSL) to set the center-link to the mid-range position
(
5.0 on the Harvest Performance Tracker [HPT]).
3. If checking float with a draper header attached, set the reel
to the normal operating position.
4. Using the HEADER DOWN switch (B), lower header fully
with lift cylinders fully retracted.
5. Turn engine off, and remove the ignition key.
6. Grasp one end of the header and lift. The force to lift (refer
to Table
4.3, page 186 ) should the same at both ends.
