1. Park the combine on a level surface, and ensure the feeder house is level.
2. Ensure the top of the oat module is level with the combine axle and the combine
res are inated equally.
3. Adjust the header so the cuerbar is 150–254 mm (6–10 in.) o the ground.
4. Set the header angle hydraulic cylinder to between B and C on indicator (A).
5. Adjust the reel fore-a to the middle posion (5 or 6 on the reel arm decal).
6. Lower the reel completely, shut down the combine, and remove the key from the
combine ignion.
7. Place wing lock spring handles (B) in the locked (upper) posion.
8. Place both le and right header oat locks (C) in the unlocked (lowered) posion.
9. Set the stabilizer/transport wheels (if equipped) to the storage posion.
Step 1: Preadjustments
Complete before adjusng oat or wing balance.
IMPORTANT:
Read your operator’s manual and complete all the setup tasks before seng the
header oat.

Ensure your machine operates at top eciency by using only clean uids and lubricants. Use clean containers to handle all uids and lubricants. Store uids and
lubricants in an area protected from dust, moisture, and other contaminants.
Break-In Inspecons
To help avoid major component service or replacement, perform break-in inspecons on your machine during the rst 50 hours of operaon. Refer to your operator’s
manual for complete break-in inspecon and adjustment procedures.

Step 2: Retrieving Torque Wrench from Storage
1. Remove special torque wrench (A) from its storage posion at the right side of the
oat module frame. Pull in the direcon shown to disengage the wrench from
its hook.
Follow these ve steps to set the header oat and wing balance:
Inspecon Instance Item
First 5 Minutes Check hydraulic oil level in reservoir (check aer rst run-up and aer the hydraulic hoses have lled with oil).
5 Hours Check for loose hardware and ghten to required torque.
Check knife drive belts tension (check periodically for the rst 50 hours).
10 Hours Check auger drive chain tension.
Check knife drive box mounng bolts.
50 Hours
Change oat module gearbox oil.
Change oat module hydraulic oil lter.
Change knife drive box lubricant.
Check gearbox chain tension.
Check deck height adjustment.
Ongoing Maintenance Intervals
Refer to the operator’s manual for a comprehensive maintenance schedule and record. Log hours of operaon, use the maintenance record, and keep copies of your
maintenance records. Following the maintenance schedule will increase your machine’s life.

Subject to change without noce

1. Before adjusng oat spring adjustment bolts (A), rotate spring locks (B) by loosening
bolts (C).
2. To increase oat (decrease header weight), turn both adjustment bolts (A) on the le
side clockwise. Repeat the adjustment at the opposite side.
3. To decrease oat (increase header weight), turn le side adjustment bolts (A)
counterclockwise. Repeat the adjustment at the opposite side.
IMPORTANT:
Ensure the torque wrench indicator readings are equal on both sides of the oat
module.
NOTE:
For FD140 and FD145 double-knife headers, set the oat as described above, then
loosen the right side oat spring bolts two full turns.
NOTE:
If the adequate header oat cannot be achieved using all available adjustments, an
oponal heavy duty spring is available. See your MacDon Dealer or refer to the parts
catalog for ordering informaon.
Step 4: Seng Header Float
1. Place torque wrench (A) onto oat pivot (B). Note the change in wrench orientaon
when checking the oat module’s le and right sides.
2. Push down on torque wrench (A) to rotate bell crank (C) forward.
3. Connue pushing down on the torque wrench unl wrench indicator (D) reaches a
maximum reading and then begins to decrease. Note the maximum reading.
4. Repeat the above steps for the opposite side of the oat module.
5. Refer to Table 1.1 as a guide for the oat sengs.
 If the reading is high, the header is heavy.
 If the reading is low, the header is light.

IMPORTANT:
Torque sengs in Table 1.1: Float Sengs are the recommended header oat sengs. If
necessary, adjust the oat values to suit the crop and eld condions.
1. Remove the wing balance linkage cover on the le side of the oat module by removing
the securing bolt, and rotang the cover upwards unl the inboard end can be lied o.
2. Place the wing lock spring handles in the unlocked (lower) posion.
3. Place torque wrench (A) on bolt (B).
4. Check that pointer (C) is properly posioned as follows:
a. Use torque wrench (A) to move the bell crank unl lower edge of bell crank (D) is
parallel to lower edge of top-link (E).
b. Ensure pointer (C) is aligned with top-link (E). If necessary, bend the pointer so it
aligns with bolt hole (J).
5. Move the wing upward with torque wrench (A) unl the pointer’s lower alignment tab (F)
lines up with the upper edge of top-link (E). Refer to Figure 8. Record the reading on
torque wrench indicator (G).
6. Move the wing downward with torque wrench (A) unl the pointer’s upper alignment
tab (H) lines up with the lower edge of top-link (E). Refer to Figure 9. Record the reading
on torque wrench indicator (G).
7. Check the wing balance on the opposite side of the header.
 If the dierence between the readings is 0.5 or less, the wing is balanced and
adjustment is not required.
 If the dierence between the readings is more than 0.5, the wing is not balanced and
adjustment is required.
Step 5: Checking Wing Balance
1. Place torque wrench (A) on bolt (B) on the le side of the header.
2. Loosen clevis bolt (C) and jam nut (J).
3. Recheck the wing balance. Refer to Step 5: Checking Wing Balance.
4. If necessary, make the following adjustments:
 If the wing is too heavy, turn clevis adjuster bolt (D) clockwise to move clevis (E)
outboard (F).
 If the wing is too light, turn clevis adjuster bolt (D) counterclockwise to move clevis (E)
inboard (G).
5. Adjust clevis (E) posion (if necessary) unl the dierence between the torque wrench
indicator readings is 0.5 or less. Tighten clevis bolt (C) and jam nut (J).
6. Place wing lock spring handles (H) in the locked (upper) posion. If the lock doesn’t
engage, move the wing up and down with torque wrench (A) unl it locks. When locked,
there will be some movement in the linkage. Repeat on the opposite side of the header.
7. If the cuerbar is not straight when the wings are in lock mode, then further adjustments
are required. Contact your MacDon Dealer.
8. Return torque wrench (A) to its storage locaon on the oat module frame.
Step 6: Adjusng Wing Balance
IMPORTANT:
Before proceeding, the header oat must be set properly. Refer to Step 4: Seng Header Float.
