Operation
The wrapper is appropriate for fruit, vegetable, fish, meat, cold food, etc. First, insert the electrical plug into a standard
NEMA 5 -15 outlet and switch on. A red light will appear. Turn the thermostat to set the desired temperature. Before
starting the operation, let the machine preheat for 5 to 10 minutes. This can be done by leaving the temperature
setting on the desired temperature. Put the wrapping material in place. Next, open up the cover plate. The wrapping
material is then placed between the cover plate and bar. Adjust the tightness of the plastic wrap. Then put the food on
cover plate and pull out the wrapping material. After finished wrapping the food, cut-off the wrapping with the heated
cut-off rod equipped with the machine. Put the wrapped food on hot plate for a few seconds. If only using the heated
cut-off rod and not wrapping any food, please turn thermostat to Min. “LO”.
Dispensing Mechanism: Axle
The film dispensing mechanism is the axle. Model accepts film roll widths up to 18" W x 8" D. Contact your film supplier
for application information regarding film thickness and color.
Heated Cut-off Rod
The heated cut-off Rod cuts the desired length of film. The temperature is factory preset at 266°F +/-50°F and monitored
and controlled electronically by a printed circuit board mounted inside the electronic box. It is field adjustable by an
electrical technician.
Hot Plate Sealing
The hot plate is a 15 3/16" x 6 1/2" aluminum casting with a built-in heating element. The operator seals the ends of the
film on the Hot Plate. The thermostat mounted under the hot plate is adjusted by a plastic knob mounted on the right
side of the hot plate. Adjustment ranges from “off” to 330°F. Temperature setting is determined by film thickness, air
temperature (kitchen or cooler) and operator’s speed.
FILM ROLE AXLE ASSEMBLY INSTRUCTIONS
1. Install Bearing Block Assembly (A) on the
left side of Base, line up holes and insert
Carriage Bolts (B) and tighten.
2. Repeat step (1) on right side of Base.
3. Loosen all Wing Nuts (C) on Bearing
Blocks on both sides to loosen top
of Bearing Blocks, and then rotate top
to expose Film Roll Axle Slots.
4. Install Film on Film Roll Axle (E),
tighten Core Adapter Wing Nut (F),
and insert in slots in the bottom of
the Bearing Blocks.
5. Rotate the top of Bearing Block to cover shaft
of Film Roll Axle, and tighten Wing Nuts (C) to the
required tension.

left Bearing Blocks.
2. Lift out the Axle Assembly. Unscrew Wing
End Cap, position Pin End Cap for correct
film width, secure with Pin and 0-Ring.
3. Position the cardboard core of the Film
Roll against the taper of the Pin End Cap.
Make certain that the film will dispense
from the bottom of the roll.
4. Replace Wing End Cap and Screw tightly.
5. Replace Axle and Film onto the Lower Bearing Blocks. Swing Upper Bearing Blocks back into place.
Tighten and adjust Wing Nuts for desired film tension.

Testing
Testing the Cut-Off Rod:
1. Disconnect the “red” CUT-OFF ROD wire from terminals 1 and 2.
2. Using an ohmmeter, measure the resistance across“red” terminal wires.
3. Disconnect “black” sensor wires from terminals 5 and 6. If the reading across “black” sensor wires is over
1M Ohms or if there is no reading -replace Cut-Off Rod.
Testing the Circuit Board:
1. Disconnect rod wires from Circuit Board. (Terminals 1, 2, 5 and 6).
2. Using D.C. voltmeter and with the switch“on”: the reading across“black” sensor terminals should be 6.5 VDC.
If it is less, replace Circuit Board.
3. Reconnect ”black” wires to board. Reading should be 3 VDC. If less than 3 VDC- replace Circuit Board.

Troubleshooting
and Maintenance
TROUBLESHOOTING
Apparent Problem Check Point Solution
Cut-off rod fails to heat properly The cut-off rod and circuit board must be
tested together. Use procedure described
herein. Check Fuse.
Replace if necessary
Cut-off rod temperature is too
high or too low
Rheostat knob on the printed circuit board
(see circuit board on page 6, Rheostat =
R5 knob) can be adjusted by an electrical
technician. Note: rheostat is fragile. Turn
clockwise to increase heat and to decrease
resistance of R5. Turn counterclockwise
to decrease heat and increase resistance
of R5.
Replace if necessary
Hot plate fails to heat or
overheats
Visually inspect the wire and connections
under the hot plate for burning and replace
if burnt. Visually inspect the lead on the
heating element for burning and replace if
burnt.
If burning or short circuiting does
not show, replace the thermostat.
If burnt replace element.
