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

tables:

Signal Words

This manual uses SIGNAL WORDS to draw the reader’s attention to safety-related information. Signal words
indicate the likelihood of personal injuries as well as the probable seriousness of those injuries, if the product is
misused in the ways described. Other signal words call attention to uses of the product likely cause property
damage. Signal words used in this manual appear below along with the meaning of each word:

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.
