System Set-up

Machine Placement
Place the semi-automatic Stretch Wrap Machine close to an area where you will be wrapping your pallet loads. Refer to figure 2 to insure the machine meets the minimum clearance space requirements. Make sure that there is sufficient room to load/unload the machine and that you do not stretch the wiring cable. Remember, you will need to provide electrical service to 120 VAC, 9.1-AMP outlet. (see Figure 2)

Floor Weight Bearing Tolerance

• The floor must be able to bear the weight of the machine, the weight of the maximum load, pus a safety factor. The floor must also be able to tolerate the stress of the machine
• operation. If the truck will operate on the same weight bearing area, add the weight of the trucks to the weight bearing stress tolerance requirement.

Figure 2

Machine Set-up

1. Place the crated machine close to the designated wrap area. Remove all shipping fasteners holding the machine to the pallet. The machine may be crated with the tower tilted down the motor cover front carriage roller removed for shipping purpose.
2. Place forks of the forklift through the tubes provided at the rear base of the module, remove the machine from crate and place it at the designated wrap area.
3. Check all internal connections to ensure there is no loose/disconnected electrical wiring.
4. Connect the motor wiring and sensor leads according to the corresponding wire numbers.
5. If the OPTIONAL ramp ( Model NO: 241020) is purchased: Select a ramp position illustrated below. The ramp can be positioned anywhere in a 180 rotation around the front of the turntable. There should be a 1/4” gap between the turntable and the ramp. The ramp should be fully supported by the floor. (See Figure 3)
