1:0 BEFORE STARTING THE MACHINE
Please refer to the following checklist before calling your Cousins Packaging
distributor or the factory for start-up assistance. This will prevent confusion and
additional expense during the start-up process.
1. Check for any freight damage, (hidden or apparent) and if found report it
to the carrier. It is the responsibility of the consignee to report any
damage incurred during shipment.
2. Uncrate and assemble the machine. If the machine is equipped with an
extended tower, erect the tower according to the instructions in Section
4:3.
3. Set the machine in place, and ensure that it is level. After leveling, lag it
to the floor.
4. Before operating the machine, remove any Styrofoam, strapping, or
shipping blocks from beneath the film carriage that may be present.
5. Actuate the Film Carriage Descent Obstruction Plate upwards and then
release, to ensure that the plate mechanism and safety switch assembly
are functioning freely. If the Descent Obstruction Plate becomes
jammed in the recessed position, the film carriage lower function
will become inoperable.
6. If the machine is being used in conjunction with a gravity exit conveyor,
ensure that the conveyor is correctly aligned with the turntable conveyor
and a minimum 1/2" gap is present between the turntable and the first full
length roller on the gravity conveyor. Mount the gravity conveyor photo-
eye to the conveyor in the indicated location. After leveling the conveyor,
lag it to the floor.
7. Connect the incoming electrical power supply and verify that the voltage
is correct, (refer to Section 4:6). Do not connect or attempt to operate
the machine without supplying proper and consistent electrical
input. Potential damage may occur that will void warranty.
8. Ensure that the limit switches mounted on the film carriage operate
between the Upper and Lower Limit Switch Strikers. These strikers are
the adjustable button-head screw and bar assemblies mounted to a rail
on the side of the tower. These strikers define the maximum travel of the
carriage. WITHOUT THESE STRIKERS AT THE TOP AND BOTTOM
TO TELL THE CARRIAGE TO STOP, THE CARRIAGE WILL OVER-

10
RUN ITS SAFE OPERATING RANGE, POTENTIALLY CAUSING
SERIOUS DAMAGE!
9. During the winter months, gear-reducer lubricants will thicken when
exposed to cold weather during shipment. Allow the machine to warm up
to room temperature for 8 hours (minimum) before attempting to operate
the machine. FAILURE TO DO THIS MAY RESULT IN BLOWN FUSES
OR MOTOR V/F DRIVE FAILURE!
10. If the machine is to be loaded and / or unloaded by fork-lift truck, it is
strongly recommended that fork-lift truck floor stops be installed to
prevent the lift truck from colliding with the conveyors.
11. READ THE MANUAL!

Before applying power or operating the machine, a general inspection is
recommended to determine if any damage has taken place during transport.
IT IS THE END-USER’S RESPONSIBILITY TO REPORT ANY DAMAGE
INCURRED DURING SHIPMENT TO THE TRUCKING COMPANY!
1. In order to obtain a clear view of all elements of the machine, carefully
remove all packaging, strapping and blocking materials, as well as any
shipping bolts.
2. Inspect the underside of the turntable for evidence of impact or crippling
of caster supports, center axle, or drive assembly.
3. Ensure that the turntable home position target mounted to the underside
of the turntable clears the Turntable Home Position Sensor by 3/8” to
1/2”.
4. Inspect visible cables and conduit for crushed sections or loose fittings.
5. Operate all control panel dials and switches. Their actions should be
crisp and free.
6. Check the carriage limit switch lever arms to ensure that they will contact
the limit switch strikers. Ensure that the upper and lower limit switch
strikers are positioned above and below the film carriage limit switches,
respectively.
CAUTION! The film carriage limit switches must operate
between the upper and lower limit switch strikers to safely limit the
travel of the film carriage!

18
4:3 Extended Tower Assembly (Optional)
Machines equipped with extended towers may be shipped in a “fold-down”
condition. Assemble the tower to the machine as follows:
4:3:1 Fold-Down Tower Assembly
Assemble the tower to the machine as follows:
1. Remove all packaging from the machine.
2. Remove the tower top cover retainer bolt and tower top cover, (the tower top
cover, may not be installed at time of shipment and may be loose shipped).
3. Round up the necessary personnel and a crane, forklift truck or other lifting
device with which to raise the tower.
4. Attach a sling or cable through the lifting eye at the top of the tower. Lift the
tower slightly until the lifting device takes up the weight, and then remove the
shipping bracket and support brace from the front of the machine.
5. Carefully raise the tower to the vertical position, taking care to keep hands and
feet and any cables clear of the tower bottom flange pinch-point.
6. Ensure that the tower is completely seated on the machine base and that the
threaded mounting holes the machine base are aligned to the mounting holes
on the tower.
WARNING! At this stage the tower is not secured to the
machine base, from this point onward exercise extreme caution
that the tower does not fall or topple forwards, at its pivot point!
7. Remove the tower front and rear guards, (refer to section 4:3:2), from the
machine.
8. Verify that the tower is completely seated on the machine base and then
fasten it down securely, using the four 1/2” –13 X 1 ¼” bolts and washers
provided. Be careful not to pinch the cable(s) located at the hinged
section of the tower!
9. Replace and securely fasten down the tower front and rear guards, (refer to
section 4:3:2).
10. Replace and securely fasten down the tower top cover.

19
11. Test for proper machine operation.
4:3:2 Tower Guard Removal / Installation
To remove the front or rear tower guard:
1. Remove the four Button Head Socket screws securing the tower guard to
the tower (two on top and two on the bottom).
2. Pull the top of the tower guard away from the tower slightly, then carefully
spread the sides of the tower guard apart, (just enough to allow them to
pass over the tower guard upper mounting bracket), then pull the top of
the tower guard away from the tower slightly past the tower guard upper
mounting bracket.
3. Lift the tower guard upwards, thereby allowing the tower guard lower
flanges to pass above the lower tower mounting brackets and then
forward away from the tower.
4. To replace the tower guard(s), reverse the procedure.
4:4 Installing the Machine
1. Prepare the installation site by measuring the equipment to be installed
and marking the conveyor centerline and the centerline of the stretch
wrap machine on the floor with a chalk-line. Refer to the System
General Arrangement Drawing provided in the manual for details and
dimensions of the system layout.
2. A fork-lift truck rated for a minimum of 4,000 pounds is required to install
the stretch-wrapper portion of the system.
3. The stretch-wrapper portion is shipped in one piece. The machine base
design incorporates two rectangular fork-lift truck lifting tubes to allow the
machine to be picked-up from either front or rear.
4. Move the stretch-wrapper portion of the system into position. The
centerline of the Turntable Conveyor is half the distance between the
inside of the chain guard on the driven side and the inside of the side rail
on the undriven side of the conveyor. This centerline must be aligned
with the centerline marked on the floor. Shim or grout as necessary to
ensure that the machine is level and supported at all points of contact
with the floor. After verifying that the stretch wrap machine is positioned
correctly and on centerlines, secure it by lag-bolting it to the floor.

20
5. Install the gravity exit conveyor(s) on the appropriate side of the stretch
wrap machine. After the conveyor(s) have been positioned, level the
conveyor sections by adjusting the threaded conveyor feet. Once the
conveyor section(s) have been leveled, secure the conveyor(s) to the
floor using lag-bolts.
6. Mount the Gravity Conveyor photo-eye to the gravity conveyor and route
the photo-eye conduit so that it passes under the conveyor. Secure the
conduit to the conveyor frame with the conduit clamps provided.
7. Mount the Machine Status Indicator Beacon Light assembly to the top of
the tower and secure it in place with the bolts provided.
8. Using the cable support grips supplied on the Remote Start / Stop
Station cable, suspend the cable to the ceiling structure directly above
the tower of the machine, and then route the cable out over the desired
loading position for the machine. Suspend the pendant control station
from the ceiling in a location where the pallet jack or lift-truck is clear of
the turntable and the operator can reach out comfortably to operate the
START and STOP push-buttons.
4:5 Pre-Operation Check and Final Assembly
1. Install and fasten the tower top cover using the two screws provided.
2. Visually check all chains for proper tension and alignment.
3. Check the film carriage limit switch lever arms to ensure that they will
contact the limit switch strikers. Ensure that the upper and lower limit
switch strikers are positioned above and below the film carriage limit
switch lever arms, respectively.
CAUTION! The film carriage limit switches must operate
between the upper and lower limit switch strikers to safely limit the
travel of the film carriage!
4. Inspect the cable running from the control panel to the film carriage and
ensure that it is unobstructed and will not snag on anything.
5. Operate all control panel dials and switches. Their actions should be
crisp and free. Open the control panel and verify that all the relays are
properly seated in their sockets.
