OPERATOR'S MANUAL
DIRECT DRIVE DIXIE DOUBLE SEAMER
Model 25D-TWIN-AL

1
INTRODUCTION
The DIXIE Model 25D-700-TWIN-AL is adaptable for
closing containers from 1½" to 4¼" diameters, up to 7" tall.
Change parts are required for closing each size container.
The Model 25D-TWIN-AL is designed with an air lift
assembly to raise containers into position with the seaming
rolls and chuck. The Model 25D-TWIN-AL may be
equipped with a single or dual switches to activate the air lift
and subsequently the seaming cycle. Alternatively, it may be
equipped with a sensor switch and programmed at the factory
for a built-in delay, suitable for your container, to allow
adequate time to place containers in the seamer before the
sensor switch activates the air lift to raises the containers into
position for the automatic seaming cycle. An average
capacity is 30 cans per minute depending on container size
and operator dexterity.
OPERATION
WITH SINGLE SWITCH: Operator positions cans with
tops then presses the start switch. The cans are automatically
raised, double seamed, and lowered. Operator removes cans
and repeats the operation.
WITH DUAL SWITCHES: Operator positions cans with
tops then simultaneously presses both start switches. The
cans are automatically raised, double seamed, and lowered.
Operator removes cans and repeats the operation.
WITH SENSOR SWITCH: Operator positions cans with
tops. After a brief programmed delay, the cans are automati-
cally raised, double seamed, and lowered. Operator removes
cans and repeats the operation.
*** INSTALLATION ***
BEFORE OPERATING YOUR DIXIE DOUBLE SEAMER
REVIEW THIS MANUAL. Also make certain that:
1. The seamer is secured directly to the floor or other stable
base with concrete drill-in anchor bolts or lag screws
using the appropriate anchoring system suitable for your
specific flooring and/or sub-flooring. Four (4) mounting
brackets with 9/16" diameter holes are located at each
corner of the cabinet base.
2. The machine is properly connected to 115 VAC, 60 Hz
electrical and 85 to 100 psi maximum air supply.
3. Auxiliary and accessory items are properly attached.
4. All moving parts are periodically oiled to prevent
unnecessary wear.
5. The machine is properly adjusted for the cans to be
closed. Inspect machine adjustments periodically to
assure proper results.
6. If used occasionally or inactive for more than a few
days, give special attention to servicing before and after
storage.

BASE PLATE PRESSURE ADJUSTMENTS
Proper base plate pressure is required to produce essential
body hooks and prevent slipping of cans during the seaming
cycle.
Each base plate has an adjusting screw (57) and set screw
(56) in its stem for making minute base plate adjustments as
follows:
1. Lift base plate out of Air Lift Shaft (805-1) or Height
Spacer and inspect the metal discs (46). If there is any
sign of undue wear or breakage of the metal discs, they
must be replaced. NOTE: If height spacers are used to
stabilize base plates for short cans, both the Height
Spacers and the Air Lift Shafts (805-1) will have 46
Metal Discs and 59 Retainer Springs.
Observe and note the original placement of the lock nut
on the threaded end of the air lift shaft before disassem-
bly. You will need to reference the original setting when
reinstalling. In order to replace the metal discs in the air
lift shaft (805-1), loosen the 5/16" lock nut, completely
unscrew the shaft and lift it out through the plunger
housing (30). Remove the retainer spring (59) from the
opening in the air lift shaft then tap the shaft against a
padded surface to dislodge the metal discs. To remove
the metal discs from a height spacer, lift it out of the air
lift shaft, remove the retainer spring and tap the height
spacer against a padded surface to dislodge the metal
discs. Replace with new discs and reassemble, making
certain that the retainer spring and metal discs are
properly seated and thattheentire assembly is adequately
lubricated (oiled).
2. Insert screwdriver into hole in tope of base plate and
remove the set screw (56) by turning counterclockwise.
3. Insert screwdriver into same hole and turn adjusting
screw (57) in the proper direction to lengthen or shorten
effective height of the base plate, as may be required for
proper tension (pressure).
4. Replace set screw and tighten snugly. It may be neces-
sary to hold the end of the adjusting screw firmly while
tightening the set screw.
5. Make certain that the base plate assemblies are properly
lubricated and replace the base plates in the plunger
housings or height spacers.
If further base plate pressure adjustment is needed, incre-
mental adjustments may be made to the air lift system as
follows:
Loosen the 5/16" locknut with a 1/2" open-end wrench; then
use a 5/8" open end wrench to turn the air lift shaft (805-1).
Adjust upward to increase base pressure, downward to
reduce base pressure. Use a 1/2" open end wrench to tighten
the lock nut against the shaft of the air lift assembly (803).
Note: Excessive base plate pressure may cause the plunger
of the air lift assembly (803) to fail to extend to its locked
position causing inconsistent lift. If the air lift operates
erratically and cans are not raised and lowered properly
although correct air pressure is maintained, a lessening of
base plate pressure may be required. Refer to the following
section on Air Filter/Regulator Adjustment for more infor-
mation.

816 AIR FILTER REGULATOR
803 AIR LIFT ASSEMBLY
AIR FILTER/REGULATOR & AIR LIFT
ASSEMBLY ADJUSTMENTS
Recommended air supplyis 80-100psi maximum. Different
types of containers may require specific psi settings. The air
pressure filter/regulator (816) on your machine has been set
at the factory for the sample containers submitted with your
order. If you find your air supply is inconsistent, or if you
change containers or lids, you may need to adjust the air
pressure filter/regulator. Too much air pressure may cause
your container to crush your lid against the chuck. Too little
air pressure will not lift the container against the lid prop-
erly. Any adjustments to the air pressure regulator should be
made in small increments until a satisfactory pressure is
achieved.
To set or change the air pressure, pull up on the black knob
on top of the regulator until the orange band is visible.
Turning the adjustment knob clockwise increases the
pressure and turning the knob counterclockwise reduces the
pressure. Adjust as necessary while observing the pressure
gauge. Do not exceed 100 psi. Push down on the adjust-
ment knob to lock air filter/regulator at selected psi to
prevent accidental setting change.
The filter element should be changed after 1 year or when a
pressure drop of 15 psi is reached. Periodically observe
condensate level through sight glass in filter and manually
drain as needed.
NOTE: Sufficient air pressure must be provided to cause the
plunger of the air lift assembly (803) to extend to its locked
position. Do not exceed 100 psi.
NEUTRAL POSITION
The machine is in a neutral position when both cam rolls
(20) are in their innermost position and both seaming rolls
are in their outermost position.
TIMING THE MACHINE
The machine is properly timed (or in neutral position) when
both cam rolls (D-20) are at their innermost position and
both seaming rolls (1st and 2nd) are at their outermost
position. There are ten (10) revolutions per seaming cycle.
Therefore, with power to the machine ON, by pressing the
actuator on the clutch/brake assembly to turn the clutch/
brake assembly one revolution at a time, the machine will
have been "timed" by or before the 9th revolution.
If it should be necessary to turn the clutch/brake assembly
less that a full revolution, proceed as follows. Turn power
to machine OFF. Press the actuator one time to release the
clutch brake. Grasp the collar (508) by hand, OR, use a
wrench to turn the chuck shaft, to turn the assembly in a
clockwise direction as needed. Turn power to machine ON
and verify that the machine is now in time.
**IMPORTANT** Once neutral position is reached, turn
off power to the machine to reset the counter. Then turn
power on and resume operation.

SEAMING ROLL ADJUSTMENTS
There are ten (10) revolutions per seaming cycle, five (5) for
each seaming roll. The function of the first operation seam
roll is to curl the cover hook and body hook into proper
position. The function of the second operation seam roll is
to complete the sealing of the can.
FIRST OPERATION
1. Put machine in neutral position.
2. With power ON, press and release the actuator on the
clutch/brake assembly four (4) times. Turn machine
OFF, then press the actuator ONE more time to release
the clutch brake. Then manually turn the clutch ONE
HALF revolution. Grasp the collar (508) by hand, OR,
use a wrench to turn the chuck shaft, to turn the assembly
in a clockwise direction. These 4½ revolutions of the
clutch/ brake assembly places the first operation seam
roll in its innermost position with the chuck.
3. While power to machine remains OFF, loosen lock nut
(16) and adjust set screw (17-A) until the first operation
seam roll is snugly in position with the chuck. While
holding the first operation gauge wire (40) in position
between the chuck lip and the ground profile of the first
operation seam roll, tighten the lock nut. The larger
diameter gauge wire (40) is the approximate THICK-
NESS of the first operation seam. Final adjustments may
be made after a can is closed and the double seam in-
spected.
SECOND OPERATION
1. Turn power to machine ON which will automatically
complete the fifth revolution. Press and release the
actuator FOUR times and turn power to machine OFF.
This is a total of nine (9) revolutions from the beginning
and puts the second operation seam roll into its inner-
most position with the chuck.
2. Use your wrench to loosen the lock nut (16), then turn
the set screw (17-A) to adjust the second operation seam
roll into position. Use the second operation gauge wire
(41) to fit the seam roll snugly in position with the chuck
then tighten the lock nut. The small diameter gauge wire
(41) represents the approximate THICKNESS of the
second roll seam. Final adjustments may be made after
a can is closed and the double seam inspected.
3. Press the actuator ONE time and turn power to machine
ON to complete the 10th revolution and cycle. This
will return the machine to its neutral position.
4. Close a can, tear down and inspect the double seam.
Make final adjustments of the seaming rolls and base
plate pressure to produce essential body hook, cover
hook, overlap and tightness recommended by the
container manufacturer or for a hermetically sealed can.
NOTE: If you are unable to obtain the essential mea-
surements recommended or a hermetically seamed con-
tainer, you may need seam rolls with different profiles.
