New Holland 499 Operator's Manual page 38

WARNING
Disengage the PTO, turn off the tractor engine
and remove the key. Wait for all movement to
stop before leaving the operator's position.
Never adjust, lubricate, clean or unplug machine
with the engine running. Failure to comply could
result in death or serious injury.
For mid position header tilt (between 4° and 7°),
insert the pin through the middle plate holes and the
cylinder rod slot, 1, as shown. This position allows the
tilt cylinder to extend the length of the slot in the
cylinder rod so the header tilts forward to a
mid-position (7°).
For maximum header tilt (4° and 10°), insert the pin
in the front plate holes, 2. This position does not
restrict the tilt cylinder stroke, and allows the header
to tilt forward to the lowest cutting height.
If a stone or obstacle is seen when the machine is
being operated in the mid or maximum position, the
header angle can be retracted to minimum tilt
position without lifting the header. Just move the
tractor valve to the raise position long enough to
retract the tilt cylinder. After the obstacle is passed
extend the cylinder by moving the tractor lever to the
lowering position.
WARNING
Disengage the PTO, turn off the tractor engine
and remove the key. Wait for all movement to
stop before leaving the operator's position.
Never adjust, lubricate, clean or unplug machine
with the engine running. Failure to comply could
result in death or serious injury.
REEL ADJUSTMENTS
The factory settings of reel position and reel speed
are satisfactory for many crops. The reel adjustment
chart lists unusual crop conditions which may require
changing reel position or reel speed for better cutting.
