OVERVIEW
The Schaefer Technologies, Inc. Model CP-4200 Capsule Polisher is easy to operate, clean and
maintain. The polisher is fast, clean and adaptable to batch or in-line processing. These factors
make the CP-4200 the best buy among the capsule polishers available on the market today.
Connect to the appropriate power source for your specific machine (see the Power Wiring Diagram
on page 16). As a standard, the CP-4200 requires only 120 volt, single phase, 60 Hz electrical
service, but it can be supplied with other electrical configurations upon request. The machine is
equipped with a reliable, solid state controller that drives a variable speed AC motor.
View Shown with Cover Removed
The CP-4200 polishes your capsules through the action of a soft nylon bristled brush that also
conveys the capsules through the polisher. Dust and powder are conveyed with a vacuum assist
through a perforated stainless steel screen. The two dust collecting nozzles may be connected
either to house vacuum or to a portable vacuum available separately from Schaefer Technologies,
Inc. All product contact parts, other than the nylon brush bristles, are of stainless steel.
With both vertical height and polishing chamber pitch adjustable, the CP-4200 can be used whether
as an in-line or a batch polisher. The combination of pitch and height adjustment allows the CP-
4200 to be used with the widest range of capsule filling machines: automatic and semi-automatic.
Although the pitch of the polishing chamber is adjustable, care should be taken so as not to make
the pitch so steep as to allow the capsules to collect at the in-feed end of the chamber. This may
lead to damage to the polisher and/or the product. Generally, the pitch should not exceed 30
degrees off the horizontal.
The CP-4200 is delivered completely assembled and ready to operate.

Unpacking, Set-up, and Operation
The Schaefer Technologies, Inc. CP-4200 Capsule Polisher is carefully packed so as to minimize
transportation damage. After removal from the crate, carefully inspect the polisher for visible signs of
damage.
Shipment contains:
•One - CP-4200 Capsule Polisher, completely assembled and operational.
•Two –Brush holding / drying cradles.
•One –Instruction Manual.
Be sure to remove the brush drying and holding cradles. When the brush is out of the polisher, these
cradles are required to support the brush to prevent the bristles from taking a “set.” It is especially
important that the cradles be used after washing to allow the brush to dry and retain its natural state.
Set the machine on a level surface and set the pitch and height of the polisher to fit your application.
The CP-4200 is designed for use either in batch polishing or as an in-line polisher. The height and
pitch of the polisher can be adjusted to fit under a range of capsule filling machines: including
semiautomatic fillers like the STI Models 10. When setting the CP-4200 for use with a Model 10, it is
necessary to increase the vertical height slightly in order to fit the in-feed of the polisher under the out-
feed of the capsule filler.
To adjust the height, turn the handle on the vertical height adjustment box. To adjust the pitch, loosen
the tilt rod lock and set the pitch to the desired angle. Loosen the tilt rod lock carefully so as to best
control the change in pitch and to prevent sudden large movements of the polishing chamber.

Unpacking, Set-up, and Operation (continued)
Connect the polisher to the appropriate power source for your machine (see the Power Wiring Diagram
on page 15). If desired, attach vacuum lines to the polishing chamber exhaust and the extractor. The
polisher performs best when vacuum is applied to remove dust and any item such as empty capsules or
loose caps and bodies. If a suitable vacuum source is not available, Schaefer Technologies, Inc. offers
a portable unit to provide the necessary vacuum source. Attach the air source for the Empty Capsule
Eliminator and/or Air Flow Brush refer to those sections for the initial settings.
NOTE: When running the numbers will show the speed setting (in HZ). When not running the word
"Stop" should be displayed. If for some reason the button "M" is pressed by mistake and "Stop" is
NOT displayed, the "M" should be pressed again until "Stop" is displayed. (Machine will NOT start
until "STOP" is in the display).
Move the ON/OFF switch to the “ON” position. Push “Run” on the control box and adjust the up or
down arrows on the variable speed controller to obtain the optimum throughput speeds for your
application. It is usually not necessary to set the rotational speed of the brush so that the rate of
discharge of the capsules is greater than the input speed. Matching the input and output rates
maximizes the ability of the CP-4200 to polish the capsules.
The pickup can be adjusted to maximize removal of powder/dust, not removed through the screen in
the polishing chamber, while minimizing rejection of good capsules. The best way to monitor the
setting is to put an air break, such as a glass or plastic bottle, in the vacuum line to collect the items.
DO NOT INSERT FINGERS OR OTHER OBJECTS INTO THE POLISHING CHAMBER WHILE

Cleanup
When your production run is complete, the machine is easily disassembled for inspection and cleaning.
If your changeover is between batches only, the following procedure is recommended:
1. Turn the speed control to the “Stop” position, move the ON/OFF switch to the “OFF”
position and unplug the CP-4200. Remove the top cylinder half by opening the six (6) cam
latches. Inspect and clean as necessary.
1. Remove the shaft coupling guard and loosen the allen set screws that hold the coupling on
the brush shaft (the motor coupling does not have to be loosened). Disconnect the coupling
and lift out the brush and polisher tube assembly. Slide the brush out of the polisher tube
and inspect for strangers. Wash the brush if desired. The brush may be washed in any mild
detergent or dish liquid. Washing with solvents is not recommended. If the brush is
washed, dry it on the cradles provided to prevent distortion of the bristles.
2. Inspect the base cylinder half for strangers.
3. Disconnect the vacuum lines from the base cylinder half. Inspect the lines for strangers and
reattach.
4. See page 17 for the empty capsule eliminator’s cleaning instructions.

blocks on each end of the base cylinder half. Make sure that the bearings are securely
seated in the blocks. Reconnect the coupling making sure that the coupling is fully engaged
and that the allen set screws are tight. Double-check the tightness of the set- screws in the
couplings. Reattach the coupling cover.
7. Reattach the top cylinder half making sure that the bearings are fully seated in their blocks.
Secure all the cam latches.
8. Inspect all the external surfaces of the polisher, including the base, for strangers: especially
in the corners formed by the frame weldment and the end brackets.
9. Plug the CP-4200 back in the electrical source and you are ready to process the next batch
of capsules.

Maintenance and Troubleshooting
NOTE: The controller program is password protected. This allows the operator to access
diagnostic parameters without being able to access the factory operational settings. Diagnostic
parameters are listed in the AC Tech manual supplied with the machine. Please contact your
Schaefer Technologies representative for any additional issues.
1. When setting up the CP-4200 for use with a capsule filler with a low discharge, such as the STI
Models 10, it may be necessary to raise the polisher slightly so that the pitch can be adjusted to
the filler’s output chute.
2. The center of gravity of the polishing chamber and motor/controller is not precise. Exercise
caution in loosening the tilt rod lock to prevent sudden movements of the polishing chamber.
Loosening the rod lock slowly will also allow for easier setting of the pitch of the polishing
chamber.
3. Brush maintenance and change out:
a. Remove the shaft coupling guard and loosen the allen set screws that hold the
coupling on the brush shaft (the motor coupling does not have to be loosened).
Disconnect the coupling and lift out the brush and polisher tube assembly. Slide the
brush out of the polisher tube.
b. The brush may be washed in any mild detergent or dish liquid. Washing with
solvents is not recommended. If the brush is washed, dry it on the cradles provided
to prevent distortion of the bristles. Air dry only.

Maintenance and Troubleshooting (continued)
c. To reinstall, slide a clean brush into the polisher tube assembly. Set the bearings
into blocks on each end of the base cylinder half. Make sure that the bearings are
securely seated in the blocks. Reconnect the couplings making sure that the
bearings are fully seated in their blocks. Secure all of the cam latches.
d. If you have more than one brush, be sure to store all spares in a cradle that prevents
the bristles from bearing the full weight of the brush.
4. When using the CP-4200 as a batch polisher for larger capsules such as a double ought (00), the
in-feed hopper may become clogged. If this occurs, gently swirl the capsules to encourage
them to flow through the in-feed opening.
5. DO NOT INSERT FINGERS OR OTHER OBJECTS INTO THE POLISHING
CHAMBER WHILE THE POLISHER IS RUNNING.
6. If output from the polisher slows down, it is possible that:
a. The powder/dust pickup is set to close the out-feed chute; adjust as required.
b. Capsules are clogged in the in-feed hopper
c. The variable speed controller may be set at too low a setting to allow the polisher to
keep up with the rate of capsule in-feed
d. The motor couplings may have been inadvertently left loose during reassembly; turn
off the controller, unplug the CP-4200, and tighten the couplings as required; plug
the polisher back in and adjust the speed controller to deliver the desired output.
7. It is normal for the motor housing to feel warmer to the touch at slower operating speeds than at
higher ones. In any event, make sure that the vents on the bottom of the housing are clear.
8. If the bearings “chatter” or are otherwise noisy, make sure that they are properly seated in the
two cylinder halves.
9. If the capsules exiting the CP-4200 are not sufficiently clean, make sure that the vacuum lines
are attached and are not obstructed. Also, make sure that the rotational speed of the brush is
not set too high compared to the rate of capsule in-feed. Reduced residence time in the
polishing chamber will reduce the polisher’s performance.
10. If you have performance or operational questions contact Schaefer Technologies, Inc. at 317-
546-4081.

Empty Capsule Eliminator
Warring: Do not over tighten Black Tip Nuts. Maximum torque is 24 in/lb.
Operation:
The capsule eliminator needs to run in the fully tilted (30 deg. Max) position to operate
properly. The empty capsules removal is controlled by the speed of the brush and the air flow
introduced into the unit. Depending on the size and weight of the capsules, the air pressure (normally
20psi +) and the speed of the brush (normally no less than 30Hz) will need to be adjusted.
The feed rate of the capsules being introduced into the capsule polisher hopper has a direct
influence on the operation. If capsules are fed into the polisher too fast, a jam can occur at the entry
into the empty capsule eliminator.
Use the following setting as a starting point:
Speed of brush - 35Hz
Air regulator - 22 p.s.i.
Cleaning (Disassembly): Note: Cleaning agent must be compatible with polycarbonate, aluminum,
delrin and stainless steel.
1. Remove the air line from the rear of the capsule eliminator.
2. Loosen the two knurled knobs (48) and remove the eliminator cover (42)
3. Remove the eliminator tube (40)
4. Remove four screws (45) from the eliminator base (38) and remove from the product
chute (37).
5. Remove the bolt (43) attaching the product chute to the leg brace of the capsule
polisher.
