INSTALLATION INSTRUCTIONS – SWA-48, POW-CAR

Review this entire instruction set before installing the stretch-wrap machine.

Consult the manufacturer in the event there are any questions or problems at the time of installation, or for information

regarding optional features not covered by the owner’s manual.

The model SWA-48 stretch-wrap machine must be removed from the shipping wood and securely anchored to the floor

before use!

• Modifications or the addition of ancillary equipment to any part of the stretch-wrap machine without prior manufacturer’s
authorization may void the machine’s warranty.

• The installation should be made so that it complies with all regulations applicable to the machine and its location. The
end-user must verify that the supplied equipment is installed so it will be suited to the environment in which it will be
used.

• Installation must be performed by suitably trained personnel with access to the appropriate equipment. The electrical
aspects of the installation should be performed by an electrician.

• Choose a location for the machine that will be free of obstructions to the largest diameter load that could be placed on
the turntable. Consideration should also be given to the approach path(s) of pallet trucks and fork trucks so that
personnel, the motor speed control, and the foot switch and its cord can be adequately protected from injury or damage.

For a typical installation, you will need the following:

i. A fork truck or hoisting means to unload the machine from the freight truck and to set it into place.
ii. A smooth, level, and adequately strong concrete surface on which to mount the machine’s frame.
iii. Concrete anchors, a masonry drill, a masonry bit, hand tools, grout, and steel shims. Consult the building’s architect or

facility engineer to determine the best size and type of hardware with which to anchor the machine to the floor.

iv. A power supply circuit and disconnect matching the motor voltage and current requirements. Refer to the machine’s

dataplate, to the labels on the control enclosure, and to the electrical section in this manual, for more information. The
end-user is responsible for supplying the branch circuit’s required (by code) overcurrent and short-circuit protection.

Note:

Static electricity is produced on the stretch-wrap film as it pulls off the roll during the stretch-wrapping of a palletized
load. This effect can be intensified by dry air conditions. If undesirable affects of static on personnel or product are
experienced, consult an ESD (electrostatic discharge) product supplier for available methods for static control.

MACHINE I NSTALLATION

1. Move the machine to its installation location by inserting the forks of a fork lift along each side of the frame until the fork

tips are under the ½” x 3” x 3” tabs on each side. Use care to avoid damage the electrical components and cable.

2. Prop the motor end of the frame up on a wooden 4 x 4 (or similar).

3. Stand the stretch-wrap mast upright on the end of the machine’s frame so that the stretch-wrap material’s carriage arm

is projecting over the side of the machine’s frame. Align the hole in each corner of the mast mounting plate with its
corresponding hole in the machine’s frame.

4. Bolt the stretch-wrap mast to the machine’s frame with the hardware provided, and wrench-tighten.

5. Remove the counterbalance retaining screw located approximately 12” up from the mast’s base plate, and cut the cable

tie holding the mast cable to the pulley at the top of the mast.

6. Anchor the machine’s frame to the floor through the 9/16” holes located at the frame corners and at the end of the

frame, under the edge of the turntable. Tighten the anchors only to the point where the frame is level.

7. Shim and/or grout under the frame sides as necessary to prevent bowing of the frame.

8. Tighten all of the floor anchors wrench-tight.

9. Bolt the motor/drive assembly onto the gear reducer using the included hardware and shaft key. When finished, the

electronic drive should be facing outward over the side of the machine’s frame.

10. Insert the turntable’s power cord plug into a standard 15A or 20A, 115 VAC receptacle. If a powered mast is installed

onto the machine, the turntable’s power cord can plug into the pigtail coming out of the mast’s control enclosure, and
the mast’s power cord can then be plugged into a 115V receptacle to supply both parts of the machine.

11. Verify that the turntable rotates and that the speed control knob provides full speed range adjustment.

12. If a powered mast is installed, verify that the mast operates and that the mast's upper and lower travel limit switches

function properly.

13. Clean up any debris, and verify that all the warning and safety labels are intact.

MATERIAL HOLDER A SSEMBLY

14. Unscrew and remove the plastic tension grip handle from the top of
the stretch-wrap material holder rod.

15. Remove the top plastic stretch-wrap material tube retainer (it should
have a bearing pressed into it) from the material holder rod.

16. Remove from the material rod any spacer tubes that will be
necessary for the stretch-wrap material width being used. Leave the
unneeded spacer tubes on the material rod. Subtract from 20" the
width of the material on the roll that will be used -- the difference is
the total length of the rod spacer(s) you will need.

17. Place the material tube onto the material holder rod, lowering it over
the bottom tube retainer. When the roll is correctly mounted onto the
rod, the material should pull from the outer side of the roll when the
material is pulled towards the turntable.

18. Place the top tube retainer into the top of the material tube, and then
drop any needed rod spacer tubes onto the top of the top tube
retainer.

19. Screw the material tension handle onto the top of the material rod.
The tension handle should screw down onto the top of either the
bearing in the top tube retainer or onto a spacer tube.

Longer film rods are available for 40" and 60" material. However, for
material lengths over 20", it will be very difficult to move the mast up
and down due to the counterweight being significantly less than the
weight of the wrap.

ROUTINE MAINTENANCE & SAFETY CHECKS – SWA-48, POW-CAR

o

Warning: Care should be taken to identify all potential hazards and comply with applicable safety procedures before
beginning work.

o

Only qualified individuals trained to understand mechanical devices and their associated electrical circuits should
attempt troubleshooting and repair of this equipment.

o

Note:

Record the maximum turntable rotation speed when the machine is installed. This will allow a reference for

evaluating drive belt slippage during future maintenance checks.

(A) Before each use inspect for the following:

1.) Frayed or damaged wires.

2.) Damage or structural deformation to the stretch-wrap mast, the machine’s frame, or the turntable.

3.) Damage to any of the machine’s control or power transmission components, particularly to the foot switch, its
guard, or its cord.

4.) Unusual noise or binding, or evidence thereof.

5.) Smooth and proper movement of the stretch-wrap mast carriage.

(B) Inspect monthly for:

1.) Worn or damaged electrical wires.

2.) Damage to the motor speed control. If the speed control’s enclosure has been broken, the drive should be re­placed.

3.) Looseness of the drive belt. See “Note,” above. Slipping of the drive belt will cause it to wear out rapidly, and the
turntable will rotate slower than intended or not at all. The belt tension is adjusted by the socket-head screws on
the side of the gear reducer mounting bracket. See the “Belt Tensioning Procedure” on the following page.

4.) Wear or impact damage to the edge of the turntable plate.

Warning:

of the plate or by a fork impacting the edge of the plate during loading and unloading. To prevent potential injury to
personnel, these must be filed, sanded or ground smooth.

5.) Damaged or worn load bearings. This is indicated by a scraping sound from the turntable during operation and by
grooves developing on the bottom side of the turntable.

6.) Wear of the turntable’s main bearing. Check that the turntable is parallel with the top of the machine’s frame and
that there is no wobble when the edge of the turntable is shaken.

7.) Excessive wear to the mast carriage slides, or to the fiber washer under the stretch-wrap material .

8.) The integrity of the frame anchors, and for cracks in the concrete around them.

9.) Unusual noises or movement during operation.

10.) All the information, safety, and warning labels being in place and in good condition.

11.) The need to clean off dirt and debris, particularly anything that has built up underneath the turntable.

In the event of a sudden and severe shock load to the turntable’s drive system, such as when the load is stopped instan­taneously while spinning due to a fork truck backing too close to the load, damage could occur to the drive system compo­nents (belt, pulleys, torque limiter, gear reducer, motor). Such damage is not covered under warranty.

The gear reducer uses .

The disassembly of the gear reducer will void its warranty, and at the manufacturer’s discretion may void all warranty of
the stretch-wrap machine.

Sharp edges or burrs can develop at the edge of the turntable plate by a fork truck’s forks scraping the top
