TRIGGER AND TRIP ARM ADJUSTMENT
1. Remove access cover on dog wheel assembly,
and open access cover on cut-off unit.
2. If necessary, center trigger (side to side) on
cam stop by adding .015" (.381mm) shims
(P/N 516237) onto trigger shaft, between the
case and trigger. Loosen set screw, and slide
trigger off the shaft to allow installation of shims.
3. Trigger must ride squarely on cam surface
when striking cam stop. If it does not, correct
by loosening the set screw on trigger and press
down on trigger until it rests on the cam. Check
spring for proper tension.
NOTE:
If the cam stop surface is not square, cam
stop and trigger MUST be replaced.
4. With trigger against cam stop, the cam follower
on trip arm should just touch the dog wheel.

5. When all adjustments are made, re-tighten lock
screw on trigger and run clutch through a few
cycles. Determine if the clutch and brake system
is working correctly, if not, additional adjustment
will be required.
CHECKING BRAKE CLEARANCE
NOTE:
As the clutch and brake liner become worn,
the clearance between clutch liner and flywheel, and
the brake lining and housing, will increase. If there
is too much clearance, the brake will not hold tight
enough and the rollers will run back down the slope
of the cam. The pressure plate will then move back
against the flywheel and cause extensive frictional
wear and heat. Eventually the brake and clutch lining
will need to be replaced. If the thickness of either
liner measures less than .095" (2.4mM) it is advisable
to install new liners.
1. Remove belt shield and cut-off blade for easier
access to clutch assembly. With pressure plate
in the locked position (ram is locked in to the
"UP" position), draw a pencil mark across the
housing and pressure plate.
2. With the engine running at half throttle or more
(cut-off will not operate properly at low speeds)
run the clutch through several cut-off cycles.
NOTE: Manually rotating the metering wheel will
allow the dog to trip the cut-off allowing the clutch
to operate.

3. After stopping at the end of each cycle, check the
pencil mark on the pressure plate. If the mark
has slipped back 1/8" (3.2mm) or more, the brake
and clutch clearance will have to be adjusted.
