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
The restrictor supplied can be installed to slow reel
lift/lower rates. Follow instructions in bag for
location and positioning of restrictor.
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.
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) at top of right
hand reel lift cylinder.
3. Start engine and activate reel lift. Left-hand
cylinder will reach full extension first, then oil
will pass to right hand cylinder.
4. Continue to activate reel lift until oil comes out
around bleed screw.
5. Tighten bleed screw.
REPOSITION WOBBLE BOX BREATHER
