(C) A cycle begins with the trigger locking the cam, which
places the rollers on the rise of the cam incline. (This has
pulled the pressure plate into its braking position against
the housing, and holds the connecting rod at the top of its
stroke, which holds the cutting blade in the up position).
(D) The metering wheel rotation, turns the dog wheel
which lifts the trigger and releases the cam.
(E) The cam rotates and the rollers run down the incline
allowing the spring to force the pressure plate against the
flywheel.
(F) The flywheel rotates the pressure plate and eccentric
shaft, to which the connecting rod is attached.
(G) The down stroke of the connecting rod (attached to
the cutting blade) produces the cutting stroke of the
blade.
(H) At the end of one revolution, the trigger slides into the
notch of the cam locking it into position. The rollers are
forced up the cam end incline, pulling the pressure plate
into its braking position and locking the cutting blade in
the up position.

If the cut-off is not operating properly, refer to the Trouble
Shooting Guide and determine what problem is occur-
ring. Use the following adjustments, as necessary, to cor-
rect the problem.
!
WARNING
When tripping the cut-off manually with the
metering wheel, BE SURE to keep hands and
feet away from all moving parts.
There may be tension on the cam stop and trig-
ger. Slightly rock the cut-off flywheel to release
the tension so the trigger can be lifted out of the
way.

SHAFT NUT ADJUSTMENT
1. Be sure trunnion rollers are in the lowest position on
the cam. This can be achieved by manually tripping
the cut-off, by rotating the metering wheel by hand.
2. Remove set screws and brass plugs in the adjusting
nut. Refer to Figure 19.

3. Lift the trigger so it does not interfere with the rocking
movement of the cam. Adjust the nut enough to allow
the cam to be rocked back and forth approximately
1/4" (6.4 mm). Using a tape measure (or ruler) verify
the 1/4" movement illustrated in Figure 20. Be sure
trigger does not interfere with cam stop.
4. Replace brass plugs, and tighten set screws. Run
through a few cycles and recheck 1/4" (6.4 mm)
measurement. It may be necessary to loosen the set
screws and readjust before final tightening.

5. Run sodcutter through a few cycles again and check
for proper operation. Since the same problem or
occurrence can be attributed to the shaft nut as well
as the trigger, it is possible that an adjustment to the
trigger may be needed.
6. When proper adjustment of the shaft nut has been
completed and the problem still exists, continue with
the following trigger adjustment.
