a. If the final knockoff point is greater than zero, adjust
the cam backward (clockwise when looking into the
trim hole) only. Do not attempt to adjust the cam
forward since you cannot reach zero without breaking
the internal stop. The cam must be adjusted 10 clicks
for a 1 digit change in the right-hand wheel. For
example, if a Preset final knockoff point was 0003, the
cam would be moved 30 clicks.
b. If the final knockoff point is less than zero, adjust the
cam forward (counterclockwise when looking into the
trim hole) only. Do not attempt to adjust the cam
backward since you cannot reach zero without
breaking the internal stop. The cam must be adjusted
10 clicks for a 1 digit change in the right-hand wheel.
For example, if a Preset final knockoff point was 9998,
the cam would be adjusted 20 clicks.
3. After adjustment, set a small number into the Preset
and deliver product. The final knockoff point should be
zero. If not, repeat the adjustments until zero is
reached.
4. Install the trim hole plugs or plate. Secure the plate
with screws and a new lockwire.
C. FIRST STAGE KNOCKOFF CHANGE.
Proper operation of the Preset depends on the correct
relationship between the first and second stage rakes
and the notches in the wheels. If this factory setting is
disturbed, the unit will not operate properly. To change
the first stage knockoff setting, perform the following
procedure:
1. Cut the lockwire that is threaded through the four
bolts securing the Register to the Preset.
2. Remove the four mounting bolts.
3. With the assembly in an upright position, lift the
Meter Register from the Meter Preset.
CAUTION: DO NOT BEND OR TWIST RAKES WHEN
SETTING FIRST STAGE KNOCKOFF. IF RAKES ARE
DAMAGED,
SEE
SECTION

FOR
TEMPORARY
EMERGENCY ADJUSTMENT.
4. Lift both rakes away from the wheels in the Preset
(Figure 4).
Figure 4. Lifting Rakes.
5. Set the first stage knockoff at a number from 3
through 900 by first depressing the SET button, then
one, two or three character wheel Preset buttons. The
Preset must be equipped with an option al three-finger
rake to obtain a first stage knockoff at a number
between 100 and 900.
6. Release the SET button by rotating the knockoff
plate.
7. Ensure that the character wheel disc inserts
(Figure 5) are located as follows:
a. For first stage knockoff at a number from 3 through
9, ensure that aIl disc inserts are installed in the
second character wheel (second wheel from right). .
b. For first stage knockoff at a number from 10 through
90, remove the disc insert nearest the top of the
second character wheel and install it in any other open
position in the wheel. Save the disc insert for future
changes in knockoff settings if there are no open
positions.
c. For first stage knockoff at a number from 100
through 900, remove the disc insert nearest the top of
the second and third character wheels. Install them in
any other open positions in these two wheels. Save the
disc inserts for future changes in knockoff settings if
there are no open positions.
