Step 2: Checking Header Float
a. On the left side of the header, lift float setting lever (A) by hand to
remove slack.
b. Fully engage the flat end of multi-tool (B) on the float setting lever.
The multi-tool should be angled toward the front of the float module.
c. Pull multi-tool (B) toward the back of the float module until lever (A) is
locked in place and will not return to its original position.
d. Move the header up and down by hand several times to reduce the
effect of friction.
e. Remove the multi-tool and repeat on the opposite side.
WARNING
Once the float setting lever has been set, remove the multi-tool
from the lever IMMEDIATELY. If the lever falls to its starting
position while the multi-tool is engaged with it, injury can occur.
f. On the left side of the float module, inspect smaller float setting
indicator (FSI) (A). Arm (B) on the FSI should point to the number 2.
• If the FSI points to a value higher than 2, the header is too heavy.
• If the FSI points to a value lower than 2, the header is too light.
NOTE: The larger numbers (C) indicate the float height while operating
the header in the field.
NOTE: If necessary, adjust the float values to suit crop and field
conditions. For more information, refer to the header operator's
manual.
Step 3: Setting Header Float
a. Loosen bolts (C), and rotate spring locks (B).
• To decrease header weight, turn both adjustment bolts (A) equally
clockwise (decreasing the value on the FSI).
• To increase header weight, turn both adjustment bolts (A) equally
counterclockwise (increasing the value on the FSI).
NOTE: Ensure the FSI values are equal on both sides.
b. After adjustment, lift the end of the header by hand and recheck the
FSI reading.
NOTE: If an adequate header float cannot be achieved using all the
available adjustments, an optional heavy duty spring is available. See
your MacDon Dealer or refer to the parts catalog for ordering
information.
c. Once the float adjustment is complete, lock adjustment bolts (A) with
spring locks (B). Ensure that bolt heads (A) are engaged and tighten
bolts (C) to secure the spring locks.
d. Use the combine to fully lower the header. The left and right float
setting levers will return to their original positions.
WARNING
Do NOT use the multi-tool to release the float setting lever. Using
the multi-tool to release the float setting lever can result in injury.

Step 4: Checking Wing Balance
NOTE: Before proceeding to check and adjust the wing balance, ensure the header
float is set. Refer to Step 3: Setting Header Float for instructions.
a. Attach flex checker cable (A) to flex checker cable lock (B).
NOTE: Images shown are from the left side.
b. On the side that you are adjusting, move spring handle (A) to the lower (UNLOCK)
position. Keep the opposite wing locked. You should hear the lock disengage. If
not, use multi-tool (B) to rotate the mechanism so that the lock disengages.
c. On both sides of the float module, place the header float locks (shown in
Figure 3) in the locked position.
d. On the flex checker plate, pinch indicators (A) and (B) together with your fingers.
e. Use multi-tool (C) to rotate the flex checker plate up until the pin reaches the end
of slot. Lower indicator (B) will move down to give the first reading.
f. Use multi-tool (C) to rotate the flex checker plate down until the pin reaches the
end of the slot. Upper indicator (A) will move up to give the second reading.
g. Refer to Figure 10 and interpret the indicator positions as follows:
• Condition A – the wing is too light; make the wing heavier.
• Condition B – the wing is too heavy; make the wing lighter.
Step 5: Adjusting Wing Balance
a. If the wing is too light (Condition A), make it heavier by turning adjuster bolt (D)
to move clevis (E) in direction (F).
b. If the wing is too heavy (Condition B), make it lighter by turning adjuster bolt (D)
to move clevis (E) in direction (G).
c. Recheck the wing balance. Adjust as required until the wing is balanced
(Condition C).
d. Move the spring handle to the upper (LOCK) position.
e. If the lock does not engage, move the wing up and down with the multi-tool until
it locks.
f. Detach the flex checker cable from the flex checker lock.
g. Repeat on the other side.
h. Return the multi-tool to its storage location, and reinstall the linkage cover.
