SECTION 9. OPERATION
Form 169006 90 Revision D
12.6 in +/-1.0
(
320 mm +/-25
)
4. Lower header to desired cutting height using
combine controls, and check spring length as
shown. Re-adjust wheels as required to
achieve range.
IMPORTANT
Continuous operation
with excessive spring
compression
(i.e. spring length
shorter than 295
mm) can result in
damage to suspension
system.
d. Set up the stabilizer/slow speed transport wheels,
if installed, as follows: Otherwise, proceed to
step e.
1. Adjust right wheels as follows:
i. Remove hairpin (D) from latch.
ii. Disengage latch (E) and lift right wheel
out of hook, and place on ground as
shown. This reduces weight of
assembly, and makes adjusting wheel
position easier.
iii. Support left wheel weight by lifting
slightly with one hand. Pull up on handle
(F) to release lock.
iv. Lift left wheel to desired height, and
engage support channel into slot (G) in
upper support.
v. Push down on handle (F) to lock.
vi. Lift right hand wheel back into field
position, and ensure latch (E) is
engaged.
vii. Secure latch with hairpin (D).
2. Adjust left wheels as follows:
i. Support wheel weight by lifting slightly
with one hand. Pull up on handle (G) to
release lock.
ii. Lift wheels to desired height, and engage
support channel into slot (H) in upper
support.
iii. Push down on handle (G) to lock.
iv. Lower header to desired cutting height
using combine controls, and check load
indicator as shown below. Re-adjust
wheels as required to achieve range
between 2 and 3 as shown below.
IMPORTANT
Continuous
operation with
excessive spring
compression (i.e.
load indicator
reading greater
than #4) can
result in damage
to suspension
system.
e. Adjust header angle to desired working angle with
the machine’s header angle controls. If angle is
not
critical, set it to “mid-position”.
f. Use the combine AHHC to automatically maintain
cutting height. Refer to your combine Operator’s
Manual and AHHC instructions for details.
NOTE
Header angle adjustments or AHHC
ground pressure control may be used
for “on-the-go” cut height adjustments.
