DANGER
To avoid bodily injury or death from

stop engine, remove key and engage lift
cylinder locks before going under machine for
any reason.
a. Raise header, engage header lift cylinder stops,
and lower header onto stops.
b. Lower the reel fully.
c. Adjust fore-aft reel position so that back end of
cam disc is approximately between 4 and 5 on
the arm decal.
d. Measure clearance ‘X’ at ends of each reel.
NOTE
The reel has been adjusted at the
factory to provide more clearance at the
center of the reel than at the ends
(frown) to compensate for reel flexing.
e. Check all possible points of contact between
points ‘Y’ and ‘Z’. Depending on reel fore-aft
position, minimum clearance can occur at guard
tine, hold-down or cutterbar.
f. If adjustment is required, refer to following
