Setup and Film Loading
1. Position unit on a flat level surface. Adjust feet (A) as needed to eliminate rocking.
2. Place film roll on top of Film Rollers (B) so that the Film Unwind (C) is coming from
bottom of roll towards front of unit and over Film Retaining Rod (D), and slightly past
Guard Lever (E).
3. Plug unit into 110 v - 120 v power source and flip Power Switch (F) on to heat Cutting
Rod (G) (approx. 3-5 mins). Rod is fully heated when film easily cuts.
4. Grasp sides of film from behind Film Retainer Rod (D) and simultaneously pull
forward and press down on Guard Lever (E) to cut excess film and create a clean
start line.
5. Adjust Film Tension Screw (H) until a slight drag is felt when pulling film to prevent
film roll from over spinning and sticking to itself. Loosen Film Tension Screw if film is
difficult to pull or rips when pulling.
6. Plug Optional Accessory Hand Iron or Hot Plate into Accessory Outlet or extension
cord. Turn on accessory and allow to heat (3-5 mins). Adjust thermostat knob until
Iron or Hot Plate is hot enough to seal film seams without melting holes in film. Turn
knob clockwise to increase heat and counter-clockwise to lower heat.

Basic Wrapping Technique
The following is a simple method to wrap bundles. There is no incorrect method, technique will
evolve as one gains experience. As long as the final product is an attractive sealed bundle you
are wrapping correctly!
1. Pull film length roughly 2x the width of the
bundle. Lay gently and smoothly across
cutting rod guard onto work area. Do not
cut film from roll.
2. Place bundle face down
on top of film. For cleanest
finished appearance. Face
up if not a concern.
3. Bring front edge of film
up and over the bundle to
the back edge of the
bundle.

4. Grasp left and right side of film
between front of guard and guard
lever.
5. Simultaneously pull film
forward and push down on guard
lever to raise cutting rod and cut
the film.
Do not let go of the film.
6. Fold cut end of film over
back of bundle overlapping
ends by at least 1/2”.

7. Place left hand on top right side edge of
bundle to hold secure. Use right hand to pull
right side of film out to straighten, then up and
over top of bundle. Pull less for delicate linens
to avoid wrinkles.
8. Repeat using opposite hands to finish left
side of bundle.
Seal Option 1: Hot Plate
Flip bundle over and place
folded seams on hot plate until
fully sealed. Adjust thermostat
knob so bundle can sit without
melting holes in film and seams
are secure.
Seal Option 2: Hand Iron
Use iron as necessary to tack
all bundle seams. Iron should
be hot enough to weld film to
itself without melting holes in
film.
Finished Bundle
Seams should be tack welded
to the point that a finger nail
across the seam will not
separate or easily open. Raise
thermostat heat if easily pealed
open or lower if melt holes exist.

CUTTING ROD TOO HOT OR NOT HEATING
1) Check the Hot Rod Fuse, F1 next to Power Switch
If a visual inspection does not verify a blown fuse, check the following:
 Neon Circuit Tester: Remove Electrical Service Panel. With the power OFF, disconnect red wire
from Circuit Board Terminal 1 and secure it out of the way without touching any metal. With power
ON, test across Circuit Board Terminals 3 and 4. If tester does not light, replace 2 Amp fuse.
 Multimeter: Set Meter for Ohms. Remove cap from fuse holder and pull fuse from cap. Check the
fuse for continuity with meter across the two fuse ends. If meter does not show continuity, replace 2
Amp fuse.
2) Test the Cutting Rod
 Neon Circuit Tester: Remove Electrical Service Panel. With the power OFF, disconnect red wire
from Circuit Board Terminal 1 and secure it out of the way without touching any metal. With power
ON, test between Circuit Board Terminal 1 and end of disconnected wire. If tester does not light,
cutting rod is bad.
 Multimeter: Set Meter for Ohms. Remove Electrical Service Panel. With the power OFF, remove
both red cutting rod wires from Circuit Board Terminals 1 and 2. Using an Ohm meter, measure
the resistance of the rod by connecting the leads of the meter to the red wires. Resistance should
read between 65 - 75 ohms. If the reading is out of this range, cutting rod is bad.
3) Check the Circuit Board
 Neon Circuit Tester: Remove Electrical Service Panel. With the power OFF, disconnect the red
wire from Circuit Board Terminal 1 and secure it out of the way without touching any metal. With
the power ON, test across Circuit Board Terminals 1 and 2. If tester does not light, circuit board is
bad.
 Multimeter: Set Meter for Voltage. With all wires connected as shown below and the power ON,
test for 100-120 volts across Circuit Board Terminals 1 and 2. If there is no or low voltage, circuit
board is bad.

** CAUTION: TESTING WITH POWER ON MAY CAUSE CUTTING ROD TO BECOME VERY HOT.
USE CAUTION TO AVOID POTENTIAL BURNS, MOVE LOOSE OBJECTS AWAY FROM UNIT TO
PREVENT POSSIBLE DAMAGE OR FIRE, AND WORK ON A NON-FLAMABLE SURFACE.**
Hot Rod works and Accessory Outlet does Not
1) Check the Outlet Fuse F2 next to the Outlet
 Neon Circuit Tester: Remove Electrical Service Panel. With power ON, test across Terminal Ends
of Accessory Fuse Holder. If tester does not light, replace 15Amp fuse.
 Multimeter: Set Meter for Ohms. Remove fuse from housing and visually inspect. If unable to verify
blown fuse, check for continuity with meter across the two fuse ends. If meter does not show
continuity, replace 15Amp fuse.
2) If Fuse F2 tests okay, test Electrical Outlet Wiring and Terminal Block
 Check Outlet Connections: Remove Electrical Service Panel. With power OFF, visually inspect all
wiring from Terminal Block to Fuse to Outlet to ensure all wires are securely connected and not
damaged.
 Neon Circuit Tester: Remove Electrical Service Panel. With the power ON, carefully insert probe
end into the Larger Neutral Outlet Slot and the other probe to the Side Terminal of the
Accessory Fuse Holder. If tester does not light and Hot Rod is working, replace Terminal Block. If
tester lights, and Accessory Fuse tests okay, replace Outlet.
 Multimeter: Remove Electrical Service Panel. Set for Meter for Voltage. With the power ON, test
Fuse Holder Side Terminal to Red Probe and Fuse Holder Bottom Terminal to Black Probe for
110 120v. If no voltage retest fuse or replace fuse holder. If 110 - 120v exists, carefully insert the
Red Probe into the Smaller Right Outlet Slot. Carefully insert the Black Probe into the Larger
Left Outlet Slot. Test for 100-120 volts across outlet. If there is no or low voltage, replace outlet.

CUTTING ROD
Rod should be cleaned of excess gum and film debris once a month or more often as needed
to prevent brown crusting of the Cutting Rod. Failure to clean rod will result in premature
failure of Cutting Rod.
General Cutting Rod Cleaning
 Turn on unit and allow to heat until film cuts easily.
 Pull and tear off 2” - 3” of wrapping film. Wad film into small baseball
sized ball.
 Turn off or unplug unit and let cool for approximately 1 minute.
 Press down on Guard Lever to raise cutting rod. While the cutting rod
is still warm, gently rub film ball back and forth across Cutting Rod to
remove any film residue.
*Use extreme care to avoid skin contact with hot Cutting Rod.
 After rod has fully cooled, blow or brush film debris from unit.
Deep Cleaning Cutting Rod of Burnt Film
*TURN OFF, UNPLUG THE UNIT,AND LET THE MACHINE COOL DOWN BEFORE
CLEANING
 Cover the unit surfaces with paper towels to protect them from over spray and debris.
 Spray and coat the Cutting Rod generously with an FDA approved “Degreaser” product.
 After soaking for a few minutes, lightly scrub the surface of the Cut-off rod with a non-
abrasive Scour Pad (Scotch-Brite™ green or blue type scouring pad).
*Avoid using sand paper, steel wool, or blade edges to clean the Cutting Rod as this may
damage the non-stick coating and cause the rod to prematurely burn out.
 Wipe the surface clean of debris and residue with clean paper towels or cloths.
ALUMINUM FRAME
*TURN OFF, UNPLUG THE UNIT,AND LET THE MACHINE COOL DOWN BEFORE
CLEANING
 The unit can be completely wiped down using mild cleaning detergent and soft rags or
paper towels. Do not hose down or submerse the unit.
