START-UP & OPERATION
To turn the machine on, plug in the power cord and wait 15 minutes to allow the heated
platen to reach operating temperature before attempting to seal trays.
Run the machine without trays and film to make sure everything is cycling properly.
1. VERIFY THE CONVEYOR IS READY TO OPERATE: Remove any extra items
that may have been placed on the conveyor and verify people are clear of the
trays and tray carriers. The guards (in-feed gate and clear exit cover) must be in
place and the emergency stop buttons must be in the up position (twist and allow
the button to pop up to reset).
2. VERIFY THE SEALING PLATEN IS CONNECTED TO THE PULL-DOWN
ARMS: Lift the black handles and hook the roller on the platen arch. This may be
left undone if it is desired to run the conveyor without operating the sealer.
3. PUSH THE GREEN “RUN” BUTTON.
4. PUSH THE RED “STOP” BUTTON TO STOP THE MACHINE WITH THE
SEALING PLATEN UP (NOT PRESSING ON A TRAY OR TRAY CARRIER).
NOTE: USE THE EMERGENCY-STOP BUTTONS OR THE SAFETY GATE
SWITCHES TO STOP THE MACHINE IN EMERGENCY SITUATIONS ONLY.
These switches act immediately and do not wait for the sealing cycle to finish.
This will leave the heater in contact with the tray resulting in over-heated
packaging materials. Stopping the machine improperly will result in a
shortened machine life.
5. TO CHANGE THE CONVEYOR SPEED: Adjust (turn) the black knob on the top
of the electrical box (lift the small stainless steel cover to access).
IMPORTANT NOTES
• Never run the machine with trays without film. Doing so can possibly cause a
jam because the trays can stick to the heated platen and be pulled out of the tray
carriers.
• Adjusting the speed of the conveyor will also change the dwell time of the sealer.
Excessively slow speeds will result in excessively sealed trays.
• If the conveyor becomes jammed, stop the conveyer and turn the power
off. The conveyor drive release knob may be pulled to allow manual movement
of the conveyor to aid removing jammed materials.

6. Load the film on the film stand as shown on the film-threading diagram located
on the machine and also shown in the diagram below.
NOTES
• The adhesive side of the film can be determined by pinching a fold and rubbing
the lid material against itself. Test both sides of the lid. The rough or tacky side
of the lid will be the adhesive side. The film supplied by Oliver is wound with the
adhesive side toward the inside of the roll. If the film is loaded in accordance
with the “FILM FEED” diagram it will be positioned properly for applying the
adhesive side of the film to the flange of the tray. If the film is loaded improperly,
it can cause the adhesive side to come in contact with the heated platen and the
film to stick to the heated platen. If this happens, the platen will need to be
cleaned.
• To thread the film through the machine, pull enough film off the roll so that you
can insert it into the slot between the tray carrier that is partially under the film
stand and the carrier that is upstream from that. After the film is hanging down
underneath the tray carrier, reach through the tray carrier and pull the film down
so that it touches the tray carriers underneath that are returning to come back up
on top. Then insert a tray into the tray carrier next to the film and cycle the
machine one time. This should seal the film to that tray and you can now fill the
rest of the conveyor with filled trays and begin running.
• The film dancer bar must move freely up and down.
• If you miss putting a tray in the machine it will not cause a problem, but the film
will be sealed to the top of the empty tray carrier. Let the machine continue to
run until that tray carrier goes around the bottom of the conveyor and comes
back up on top, then remove the piece of film.
1908S20074
1-11
• It is important that the roll of film is centered on the conveyor. There are white
plastic film guides on either side of the film roll. These guides can be adjusted
from side-to-side by pushing them with your hand. If the film is not centered,
move both guides toward the side that the film needs to go to. It may take a little
bit of running time before you can tell if the film is in the correct position.
7. Place filled trays in tray carriers. Take care to avoid spilling food product on the
flange of the tray. Contamination of the flange can result in poor heat seals.
8. After a few trays come out of the machine, stop and inspect the acceptability of
the seals. If the seals are not acceptable or the trays do not come out of the
machine smoothly, refer to the trouble shooting guide.
9. The machine can be stopped at any time by pushing the stop button down.
When started again, the machine will pick up sealing where it left off.
NOTE
• IT IS NOT RECOMMENDED TO LEAVE THE MACHINE PLUGGED IN IF IT IS
GOING TO BE OUT OF OPERATION FOR AN EXTENDED PERIOD OF TIME.

CLEANING AND MAINTENANCE
WARNING
Disconnect the power from the Model 1908 and allow the unit to cool before
performing cleaning and/or maintenance procedures.
These cleaning recommendations are not meant to replace or supersede plant-standard
manufacturing procedures or regulatory requirements. Do not immerse, hose down,
pressure wash, or otherwise soak electrical switches, electrical control box,
mechanical drive box, and electrical connections. Avoid getting these areas wet.
If your cleaning procedure involves liquid amounts greater than the use of a
damp cloth, protect these areas by shielding with plastic bags.
1. Heater Platen Cleaning:
CAUTION
• CAUTION HOT: The platen and surfaces around it may be very HOT! Care must
be taken to protect yourself and others. If the platen will be cleaned while it is still hot
make sure hand protection is used to prevent skin contact with the platen.
If food product comes in contact with the surface of the platen it tends to burn on and
become hard. This results in an irregular surface on the face of the platen that can
result in poor seals. If this happens, it will be necessary to remove this burnt on food
material.
1.1. Remove the In-feed guard.
1.2. Tip the film roll holder forward until it is resting on the side rails of the machine.
1.3. Remove the discharge cover and heat shield by removing the 4 black plastic
screw knobs on top of the covers and lift the covers off.
1.4. Release and tip the heater platen up by pulling the large black handles and
rotating the heater platen upwards until it is against the stops. The bottom of the
heater plate will be easily accessible.
1.5. Clean any food residue off the heater platen. When cleaning the surface of the
platen care must take to avoid scratching or gouging the surface. DO NOT
SCRAPE THE SURFACE OF THE PLATEN WITH SHARP OBJECTS AND
AVOID THE USE OF METAL TOOLS. Instead use a plastic or soft-metal
scouring pad such as Scotch Brite® or Chore Boy® brands provide a safe and
effective means of cleaning the heated platen. Wipe all surfaces with a
sanitizing agent after cleaning.

2. Tray Carrier Cleaning:
The tray carriers should be removed and cleaned daily. It is better to remove them
for cleaning rather than trying to clean them in the machine. The tray carriers can be
placed in your dishwasher for cleaning if you desire. Care should be taken so that
the rubber gaskets do not become damaged.
2.1. Disconnect the conveyor from the drive unit by lifting the cover on the side of the
machine and pulling the knob out. The knob will stay out if it is twisted ¼ turn
while pulling. This allows the conveyor to be moved manually.
The carriers should be removed in the middle of the in-feed area on the top of the
conveyor.
2.2. Lift up on two tray carriers next to each other and push one to one side while
pulling the other it to the other side. This spreads the chains so the pins can be
disengaged. Completely remove the two carriers as shown.
The picture below shows how to remove the tray carriers.
2.3. As the carriers are removed, the conveyor must be pulled forward to keep
getting to the remaining carriers. To move the conveyor forward, grasp a tray
carrier toward the infeed-end of the machine and pull the conveyor forward.
This must be done with the conveyor disconnected from the drive (step 2.1).
2.4. Wipe all surfaces with a sanitizing agent after cleaning.
2.5. Replace the tray carriers after cleaning the remainder of the machine.
1908S20074
1-15
Note: Look for a white painted chain link to center on the side of the first tray
carrier re-installed to get the tray carrier/ chain timing correct.
Note: When replacing the tray carriers, it is extremely import to make sure that
all four pins on the conveyor chains are fully engaged in the holes of the tray
carrier. If the tray carriers are put in on an angle because the pins are not
engaged on one side, it could cause damage to the cutter assembly.
2.6. Re-engage the conveyor drive by twisting the release knob until it snaps in.
Move the conveyor manually until the pin locks in and prevents further
movement.
3. Clean the remainder of the machine:
3.1. Remove the two bottom pans by sliding them toward the discharge end of the
machine. Note: the pans may need to be jostled up and down slightly to get
them over bolt heads and other obstacles.
3.2. Clean the cutter assembly with a mild cleaner or sanitizing solution and a damp
cloth.
NOTE
The use of plastic or soft-metal scouring pads such as Scotch Brite® or Chore
Boy® brands provide a safe and effective means of cleaning the cutter assembly.
Wipe all surfaces with a sanitizing agent after cleaning.
3.3. Clean the pans and remaining surfaces of the machine with a mild cleaner or
and a damp cloth. Wipe all surfaces with a sanitizing agent after cleaning.

4. Conveyor Chain Maintenance
4.1. Once a month the conveyor chains should be lubricated with vegetable oil such
as cooking spray. If you use hose-down cleaning, this should be done twice a
month.
SPRAY CHAINS WHILE
MACHINE IS CYCLING
4.2. Once a month the conveyor chains should be checked for proper tension. The
tension can be checked by lifting the lower tray carriers at the middle of the
machine. If you can easily lift them up more than 3 inches, the chains are too
loose and should be tightened by adjusting the tensioners at the infeed-end of
the machine. Loosen the locking nuts and turn the adjusting screws clockwise
to tighten the chains then retighten the locking nut. It is important to adjust both
sides equally. The easiest way to do this is to count the turns that you tighten
one side and then do the same on the other side. The best method is to adjust
each side in ¼ turn increments and then recheck the chain tension.

Products Company 24 Hour Emergency Service number @ 1 800-253-3893.
Please have the serial number of your machine available to give to the Customer
Service representative.
Before calling for assistance please check the list below to see if the problem you are
experiencing is listed. If it is, try the corrective action items listed for that problem
before calling for assistance.
OPERATION ISSUES:
Symptom:
Machine does not power-up
(does not run and/or the
heater platen does not get
hot)
Machine receives power, but
the conveyor does not move
when the start button is
pushed.
Corrective Action:
1. Verify the machine is plugged in to a working
outlet.
2. If the platen does not heat, unplug the power
and remove and inspect the fuse (located in the
electrical panel, see section 4). Replace if
necessary (see parts list).
3. Verify the two e-stop buttons are not engaged
(pushed down). Twist the button to release it to
the ready to run position.
4. Verify the in-feed guard is installed in the correct
position (stainless steel gate hung in front of the
heater platen).

(plastic cover).
6. Verify the speed control knob is turned to 75% to
100% of the speed range.
1908S20074
1-18
Conveyor does not move
when the start button is
pushed and steps 1-4
(above) have been taken.
A mechanical jam is
preventing the conveyor from
moving as indicated by a red
light in the electrical box
window.
7. Turn the speed up to 100%. Look in the window
of the electrical box under the conveyor outfeed. A green or red light should be visible.
--A green light indicates the motor is receiving power
and should be able to run. If only a green light is
visible, go to step 12.
--A red light indicates a mechanical jam— turn off the
main power immediately. Go to step 8.
--No light indicates power is not available to the motor
because a guard, e-stop switch, or main power switch
is tripped. Go to step 13.
8. Mechanically disconnect the indexer drive from
the conveyor by pulling the disconnect knob and
turning it 90 degrees (1/4 turn) so it stays out.
9. Mechanically disconnect the platen by pulling
the large black plastic handles. Allow the platen
springs to hold the platen up off the conveyor,
but do not remove guards and lift it as you
would for cleaning.
10. Manually pull the conveyor. If it pulls freely, the
problem is in the transmission box (Call for
service). If the conveyor does not move, look for
a jammed tray, an incorrectly installed and/or
wedged tray carrier, excessive food build-up,
excess film wrapped around a conveyor part or
the cutter, or excessive chain tension.
11. If no correctable cause is found for the jam, call
for service.
