SWA, MANUAL
The tension applied to the roll of stretch wrap determines how much the material stretches as it wraps
around a load. Tension is also adjustable. To increase tension, turn the rod tension wing nut (item no. 1,
clockwise. To decrease tension, turn the wing nut counterclockwise.
To begin wrapping a load, set the tension to allow the wrap to easily pull off of the roll. Fix the end of the
wrap to the load, for example by tying it to the pallet; then press the pedal control to rotate the turntable.
Next, tighten the wing nut to achieve the desired material tension after wrapping the material around the
load once or twice to prevent it from coming loose. To wrap the load, move the wrap holder assembly up
and down as necessary to achieve the coverage desired for the load. Cover the entire load with 2-3
layers of wrapping material. To complete the wrapping process, cut (or tear) the material and press the
end against the side of the load.
Inspections & Maintenance
DO NOT use the wrapping machine until all problems discovered during an inspection have
been resolved.
Before each use, inspect the listed components:
1. Wiring: examine the wires for fraying and damage.
2. Mast, turntable, and frame: Handrails: check each structure for bends, warps and cracks.
3. Power transmission and control equipment (particularly the foot pedal): inspect each component and
associated guards and cords for damage.
4. Operate the wrapper: observe and listen to the machine as it operates for unusual noise or
movement, or binding.
5. Product labels: all labels should be readable and located as shown in the “Labeling diagram” on p.
17. If a label(s) is unreadable or missing, order a replacement.
NOTE:
Label appearance and content is subject to change over time, and consequently,
replacement labels might differ from labels shown in the manual supplied with the unit.
At least 1 time per month, inspect:
1. Electrical wiring: closely inspect wiring for regions of significant wear, cuts, frays, and other damage.
2. Fasteners (hardware): check fasteners for looseness and damage. Tighten all loose fasteners;
replace any that are damaged: Bolts, nuts, washers;
3. Turntable drive belt: inspect the drive belt for significant wear and looseness. If the belt is significantly
worn, replace the belt. Operate the turntable and compare the current maximum rotation speed with
the speed recorded when the machine was first installed. If the top rotation speed is slower than the
initial figure, adjust the tightness of the belt. See
, pp. 14-15).
4. Motor speed control: if the speed control enclosure is broken, then the drive should be replaced.
5. Turntable: examine the turntable for significant wear and impact damage. Sharp projections might
develop along the edge of the turntable. Sand or grind off all projections, burrs, etc.
6. Load bearings: operate the turntable and listen for scraping sounds. If the turntable is noisy while it
rotates, replace the load bearings.
7. Turntable main bearing: the top of the turntable should be parallel to the supporting frame; it should
not wobble (press down and pull up on the edge of the turntable).
8. Carriage slides: inspect the slides for excessive wear.
9. Fiber washer (see item no. 2 on
): check the fiber washer of the (shrink wrap) material holder.
Make sure that it is not significantly worn.
10. Anchoring points: check each of the anchor bolts and the concrete. The machine should be solidly
fixed to the floor. Tighten bolts, if necessary. Also inspect the concrete around each bolt. It should not
be cracked, chipped, etc.
11. Labels: confirm that all labels (shown in
on p. 17) are present, undamaged and
readable.
12. Overall condition of wrapping machine: the structure should be clean, square and rigid, and free of
rust and corrosion. Remove dirt and debris. Do not use the machine if the base is excessively rusted
or corroded.
