Specifications

Thank you for purchasing a semi-automatic stretch wrap machine made by Vestil Manufacturing Company (“Vestil”). Our wrapping machines are designed for dependability and incorporate numerous safety-enhancing features. Although use and maintenance procedures are relatively intuitive, all persons who might use or maintain this product must familiarize themselves with the instructions provided in this manual.

Notable features of standard models include:

• Carousel rotation controlled by a (foot) pedal switch connected to an 8 foot cord. The standard 115V, variable AC motor allows adjustable rotation speeds of 3-12 rpm and includes soft-starting and stopping capability.

• Adjustable stretch-wrap tension controlled by a friction-brake assembly. Film placement is controlled manually by moving the carriage assembly up and down on the vertical mast. An easy-to-release, hand operated carriage-brake allows the carriage to move freely making film application fast and simple.

• Adaptability to use stretch wrap rolls 10"-20" long.

• Minimal assembly is necessary. Each wrapping machine is shipped with the mast disconnected.

Assembly simply requires raising the mast and bolting it in place.

• The stretch-wrap delivery mechanism can be upgraded to a 115V, single phase, AC-powered mast option (PMO).

• Ability to be used in conjunction with an optional ramp, which allows the operator to load and unload the machine with a pallet truck.

Dimensions and other product specifications of standard wrapping machine models appear in the following

Hazards of Improper Use

Vestil diligently strives to identify foreseeable hazards associated with the use of its products. However, material handling is inherently dangerous and no manual can address every conceivable risk. The end-user ultimately is responsible for exercising sound judgment at all times.

Failure to read and understand the entire manual before assembling, installing, using and servicing the product is a misuse of the product. If this product is used improperly or carelessly, the operator and/or bystanders might sustain serious personal injuries. To reduce the likelihood of injury:

• DO NOT modify the product in any way UNLESS you first obtain written approval from Vestil. Unauthorized modifications automatically void the Limited Warranty and might make the product unsafe to use.

• Read the manual to refresh your understanding of proper use and maintenance procedures.

• DO NOT exceed the maximum rated load. See Label 287 in Labeling diagram on p. 17.

• DO NOT stand or sit on the turntable or on the load at any time.

• Loads must not extend over the shelves of the cart.

• Install the machine ONLY on even, level surfaces where the machine will not be exposed to the outdoor

environment.

• Keep hand, clothing, etc. out of contact with all moving parts of the machine.

• BEFORE using the wrapping machine, instruct all bystanders to stand away from the machine and the item to be

wrapped.

• The person operating the turntable should stand where the mast is between him and the turntable.

• DO NOT activate the turntable UNLESS the load is centered on it and stable. Be prepared to stop the turntable,

because rotation can cause the load to shift and become unstable. Because an unstable load might topple during the wrapping process, EVERY person involved should remain far enough away from the machine to avoid contact with the load if it falls. Higher rotation speeds can cause an unstable load to be flung from the turntable.

• DO NOT continue to use the machine if you observe abnormal motion or noise. Immediately tag the unit “Out of service” and report the problem to maintenance personnel.

• DO NOT attempt to resolve any problem(s) with the product unless you are both authorized to do so and certain that it will be safe to use afterwards.

• Inspect the product before each use:

A. DO NOT use this product if the inspection reveals structural damage. Examples of structural damage include, but are not limited to, the following: 1) Cracked, broken or significantly deformed frame, mast or turntable; 2) cracked welds; 3) corrosion, severe wear, or other condition that affects the ability of the product to support weight. Replace each part that fails to pass an inspection, and DO NOT use the product until it is fully restored to normal condition. B. DO NOT use the product if any unusual noise or movement is observed. If a malfunction occurs, remove the unit from service and notify your supervisor & maintenance personnel about the issue.

• DO NOT use this device UNLESS all product labels (see Labeling Diagram) are readable and undamaged.

Proper use, maintenance, and storage are essential for this product to function properly.

o Always use this product in accordance with the instructions in this manual and consistent with any training relevant

to machines, devices, etc. used in conjunction with this product.

o Periodically lubricate the chain. o Keep the product clean & dry. o Vestil uses only quality parts to make the equipment we manufacture. Vestil bears no responsibility for problems

that result as a consequence of using unapproved replacement parts. To order replacement or spare parts for this equipment, contact the factory.

when items are stretch wrapped. The static effect can intensify in dry air. To reduce the effects of static electricity on the wrapping machine, always ground the control to the frame of the machine. If significant static electricity is experienced, bond the frame of the machine to a driven ground rod (see National Electrical Code for details of driven grounding electrodes).

1. Move the machine to the desired installation location. Install the machine only on an even, level surface.

2. Lift the mast into the upright position. Insert the mast through the mast sockets with the stretch wrap carriage pointing towards the turntable.

3. Insert the squeeze bracket into the gap between the mast and the socket as shown below; then tighten the set screws against it using a plate flexion during use even with the squeeze angle firmly secured against the mast.]

4. [Manual models] Manual wrapping machines counterbalance the combined weight of the wrapping material and the material carriage with a counterweight inside the mast. The machine is shipped with the carriage raised to the top of the mast and the counterweight at the bottom of the mast. The retaining screw (through the mast) prevents the counterweight from sliding inside the mast during the shipping process, but must be removed now. The head of the screw is located approximately 12 inches from the base of the mast.

5. Fasten the machine to the floor with anchor bolts. There are 4 anchoring points: 2 in back and 2 under the turntable. Each of the 4 anchor tabs has a engineer should evaluate the installation site and select the location.

6. Shim and grout under the frame.

7. Connect the wrapping machine to an AC power source: Insert the turntable power cord into a 15A, 115 VAC receptacle.

• [Powered mast models] Powered mast models have 2 power cords: one for the turntable and another for the wrapping carriage. The 2 cords can either both be plugged into a power outlet, or be connected and plugged into an outlet. To connect the cords, plug the turntable power

Belt Tensioning Procedure

The wrapping machine uses 2 belts to rotate the turntable and the tension of each belt occasionally requires adjustment. For instance, if the turntable vibrates or rattles, the tension of the lower belt needs to be adjusted. Similarly, if the turntable drive motor (or the metal box that supports the motor) vibrates, the tension of the upper belt should be increased.

1. Adjust the tension of the upper (small) belt.

• Loosen all four bolts (1) adequately to allow the motor mounting bracket to slide. [NOTE: Only three bolts are shown in the diagram above.]

• Loosen the jamb nuts on the set screws (2).

• Remove the end guard by removing both end guard bolts.

• Assess the adequacy of belt tension by doing the following:

a. Locate the access opening (C); then insert a metal rod approximately 3/8” x 10” long, into

the access opening. The rod must have a smooth, flat end without sharp projections that might damage the belt.

b. Locate the belt with the end of the rod. Lightly contact the belt at the point approximately

halfway between the two pulleys. The rod should be perpendicular to the belt. Do not press the rod against the belt. Make a first mark on the rod that is flush with the top of the access opening (C). Make a second mark

/8 in. above the first mark.

Table of Contents Rev. 9/19/2018 SWA, MANUAL

c. Using a “pencil type” compression spring scale, measure the force required to push the

rod

/8 in., that is, the force required to move the rod inwardly so that the second mark is

flush with the top of the opening (C).

d. If necessary, adjust the tension of the belt. If the belt is new, the force measured by the

spring scale should equal 16 lbs. After a belt is broken in, the force required should be between 8-12 lbs. To adjust belt tension, use a

/16 in. Allen wrench to turn the set screws

(2). To increase tension, turn the screws clockwise. To decrease tension, turn the screws

counterclockwise. Turn both set screws the same amount.

• When belt tension is proper, retighten the jamb nuts on both set screws firmly against the bracket tabs; then reinstall the end guard and tighten all four of the motor mounting bracket bolts (1).

2. Adjust the tension of the lower (large) belt.

• Loosen all 4 power unit subassembly bolts (A). [NOTE: Only 2 bolts are shown in the diagram; the other bolts are on the opposite side of the subassembly.]

a. Locate the access opening (D); then insert a metal rod approximately 3/8” x 10” long, into

the access opening. The rod must have a smooth, flat end without sharp projections that might damage the belt.

b. Locate the belt with the end of the rod. Lightly contact the belt at the point approximately

Use Instructions

Standard SWA-50 and -70 wrapping machines must be used indoors. They are designed for moderate duty, intermittent cycling and will wrap loads weighing up to 4,000 pounds (1,818.2kg). The net weight of the pallet or skid and the items stacked on the pallet must not exceed 4,000 pounds. The load rating appears on Label 287, which is affixed to the machine as shown in the Labeling diagram on p. 17.

Place a load on the turntable

DO NOT drop loads onto the turntable, because shock loading will cause the load bearings to fail prematurely. DO NOT exceed the load rating; the drive system might be damaged or fail prematurely.

To protect the load bearings, be careful when loading the turntable and slowly apply loads to the turntable. In particular, take care to not drop items on the table or to slam the tines of your fork lift on it.

Wrap the load Standard model wrapping machines are equipped with a constant-pressure (dead man style) foot pedal control. As long as the pedal is pressed, the table will rotate. When the pedal is released, the turntable will coast to a stop.

Turntable rotation speed is adjustable. To increase or decrease the speed, turn the knob on the Delta controller (see p. 11) clockwise or counterclockwise, respectively. The number displayed on the screen of the control is the approximate number of revolutions per minute.

Page 16

Table of Contents Rev. 9/19/2018 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, on p. 13)

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 Belt tensioning procedure

, 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 p. 13): 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 Labeling diagram

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.
