UNLOADING & ASSEMBLY
ATTACH HEADER
CAUTION: Read the Operator's Manuals carefully to familiarize yourself with procedures and
controls before attaching header to windrower or combine. Attaching instructions are
provided in the Windrower Tractor and Combine Adapter Operator's Manuals.
BLEED HYDRAULIC SYSTEM
Header Lift Cylinders
Raise and lower header a few times to allow trapped air to pass back to the reservoir.
Reel Lift Cylinders
CAUTION: Take care during this procedure as air in the system can cause the reel to raise
and lower erratically. Keep body and hands out from under reel and reel support arms.
IMPORTANT: If a pick-up reel is installed: To prevent
twisting damage to reel, complete this procedure before
installing finger pitch adjustment bolts. See Pick-Up Reel
Operator's Manual.
1. Fully lower header and reel.
CAUTION: Bleed screw (A) may be
forced from hole by hydraulic
pressure. Do not loosen screw too
quickly or too far.
2. SLOWLY loosen bleed screw (A) in right hand
reel lift cylinder. (For 36 ft. header, bleed
screw is in left hand cylinder.)
3. Start engine and activate reel lift. Left hand
cylinder will reach full extension first, then oil
will pass to right hand cylinder. (For 36 ft.
header, sequence will be: center cylinder, R/H
cylinder, L/H cylinder.)
4. Continue to activate reel lift until oil comes out
around bleed screw.
5. Tighten bleed screw.
REPOSITION WOBBLE BOX BREATHER
Unless header will be transported on a trailer that carries
headers upright, swap position of plug (B) and breather
(C) at wobble box, so breather is in rear hole.
ADJUSTMENTS & CHECKS
Perform final adjustments and checks as listed on the "Pre-
Delivery Checklist" (yellow insert) to ensure the machine is
field-ready. Use the Operator's Manual for directions.
