Roller Tension System
The rollers are one of the most essential elements of the entire system. Proper
maintenance and care are needed to keep them in optimal condition.
IMPORTANT: Remove roller tension when the machine is not in use to avoid developing
a flat spot in the rollers, which degrades machine performance. Apply tension prior to
bucking as shown below, and remove roller tension after use.
Applying Roller Tension
Using the provided 5/16” hex key, tighten the two bolts located on top of the hood until
fully seated with lock washers pressed flat.
Removing Roller Tension
Using the provided 5/16” hex key, loosen the two bolts located on top of the hood.
These bolts will only back out ~5 full rotations. Once you feel the bolt provide resistance
stop loosening. These bolts will not be loosened to the point of removal.
§ ATTENTION – Do not make any adjustments to the tensioning system of
the machine, the tension has been preset and will not need adjustment
unless otherwise directed by MUNCH Machine.
Hood
The hood of this machine is designed to protect the user from moving internal parts of
the machine, while allowing access for cleaning and maintenance. The hood must be
installed and secured properly before any operation.
§ WARNING – Keep all shields, guards and safety devices installed and in
proper working order at all times.

11
Hood Removal
Unplug the machine. Approach from the back side and locate the two thumb screws on
the top of the hood. Also locate and note the position of the hood mount pegs, located
on the lower left and lower right sides of the hood. Loosen and fully remove the two
thumb screws one at a time while supporting the hood with the opposite hand.
§ CAUTION – Supporting the hood with one hand while removing the
thumb screws is crucial to prevent dropping the hood and possibly
causing injury.
While still supporting the hood, place one hand on each left and right side of the hood
using the lower edge for additional support, lift upwards on the hood while shifting it
towards your body (away from the machine) to allow the hood to clear the two hood
mount pegs.
Hood Installation
Unplug the machine. Approach the machine from the back side and locate the two hood
mount pegs on the lower left and lower right sides of the bucking head side plates. Also
locate the two roller tension bolts located on top of the force cap.

12
Lift the hood keeping the 4 holes upwards and away from your body, the curvature on
the back of the hood should be the closest point to your body. Tilting the top edge of
the hood slightly forward, align the Roller Tension Bolts with the top 2 holes on the
Hood but do not set the hood down on the Force Cap. Leave about 1 inch of gap
between the Hood and Force Cap as you slowly pivot the bottom of the hood
downwards to the point where the notches on the hood and the hood mount pegs are
centered on each other. Lower the hood so that it makes contact with the pressure
plate. The two bolts should easily pass through the 2 larger holes on top of the hood,
and the notches should seat on the hood mount pegs tight against the bucking head
side plate on both the left and right side.
§ CAUTION – Supporting the hood with one hand while installing the
thumb screws is critical to prevent dropping the hood and possibly
causing injury.
Locate the 2 unused smaller holes on top of the hood, align them with the threaded
holes in the force caps, install the two thumb screws, and firmly tighten. Do not force
the thumb screws - ensure that threads are aligned properly before tightening. If you
feel any resistance, unscrew and restart. The thumb screws come pre-treated with food-
grade anti seize, which may need to be reapplied over time.
Direct Contact Surfaces
The food-grade stainless steel Faceplate and Die Plate are designed to be the only
machine surfaces in contact with product and are compatible with a cGMP compliant
workflow. Daily cleaning of these plates with the proper cleaning products (See

rotation on a concrete or paved surface.
Outdoor Wheels
Outdoor machines will come with 8” flat free outdoor tires. These allow for movement
on rough surfaces.
Machine Guarding
All guards must be in place before any operation of the machine. The die plate must be
installed properly, the hood must be installed properly, and the Control Panel must be
closed and locked.
To prevent processed stalk material from jamming in the outfeed side of the machine it
is not possible to closely guard the outfeed area. To ensure personnel cannot reach into
the rollers during operation a barrier guard on the sides and back of the machine must
be in place. Four posts (48” tall) and a metal or plastic chain set 36” away from the
machine and connected to the sides of the machine must be in place during operation.
Signs on the chain advising personnel to stay out when the machine is running must be
on the chain or posts.

17
Solid panels or rigid mesh panels may also be used and can be placed closer to the
machine depending on the mesh opening size (US companies should refer to OSHA
regulations). Consult with your local work place safety officials to ensure you meet your
relevant regulations.

loosened to the point of removal.
o Clean the machine using the method defined below.
o Store the machine in a clean, dry, sheltered location.
Cleaning
This machine will perform at its best when cleaned after each use. The machine is built
to wash-down rated specification ns, but some precautions need to be adhered to.
Recommended cleaning materials
o Rubber gloves
o Stiff plastic bristle brush
o 70% rubbing alcohol, or citrus based cleaner , in a spray bottle
§ ATTENTION - Do not use alcohol stronger than 70%. Anything higher will
have an adverse effect on the rollers and cause premature breakdown.
Use of high content alcohol will void the warranty.
o Clean, low-lint rags
o Plastic razor blades or application squeegee
With the Machine powered off, remove the hood. Use 70% alcohol in a spray bottle to
spray down rollers and interior sides of the Bucker Head and Lower Cross Plate. Use a
stiff bristle brush to scrub the rollers, then rotate the rollers by hand and repeat with
additional alcohol. Do the same for any debris that is left on the Bucker Head or Lower
Cross Plate. Once everything has been scrubbed down, apply 70% alcohol to a clean rag
and wipe down rollers, Bucker Head, and Lower Cross Plate until clean.

19
Pressure Washers
The entire machine may be washed using water from a hose. The Rollers, Faceplate, Die
Plate, and Frame may be cleaned using a high-pressure washer. Do not direct a high-
pressure stream at any electrical components, Control Buttons, Motor, Cables or the
Bearings.
§ ATTENTION – Improper use of a pressure washer may cause damage to
your machine. Avoid spraying directly into any electrical components,
Control Buttons, Motor, Cables or the Bearings.
Use of a pressure washer is not recommended for daily cleaning of the machine. An
annual deep clean with a pressure washer will keep the machine running properly, while
not creating additional wear on the components.
§ ATTENTION - Properly dry and protect and lubricate all components of
the machine after using a pressure washer for cleaning.
Maintenance
General maintenance on the machine is minimal. The machine does have a few wear
parts that the user needs to be aware of and maintain to keep the machine in good
working order.
Lubrication
The Take Up Bearings and Flange Bearings will occasionally require greasing. Grease
zerks are installed on each bearing for use with a grease gun. Due to the machine
running at low speeds and low temperatures the machine does not use grease as quickly
as other equipment.
§ ATTENTION – Damage can occur to the bearing seals if they are over-
greased.
Bearing Lubrication Intervals
o High use situations (daily use, year-round) require application of one grease
pump per bearing every 3-4 months.
o Low to Moderate use situations (Seasonal use) require application of one grease
pump per bearing 1 time per year.
Pump slowly; one grease pump will add enough grease for this application. One of the
primary causes of bearing damage is over greasing.
§ ATTENTION – Damage can occur to the bearing seals if they are over-
greased.
Recommended Food Safe Lubricant:
§ Lubriplate FGL-2 - product number L0232

20
Side Plate Lubrication
After a thorough cleaning of the machine, it will be necessary to lubricate the side
plates where the Take Up Bushings and Side Plates interact to insure proper movement
of the Take Up Bearings when loosening or tightening the Roller Tension System. This
grease application can be applied by a gloved hand or a small brush.
Recommended Food Safe Lubricant:
§ Lubriplate FGL-2 - product number L0232
Rollers
The Drive Roller and Follow Roller should be inspected during the cleaning process after
each use. The rollers are a wear part and will need to be replaced occasionally, and only
after significant wear is present on the rollers surface.
Proper care of the rollers starts with proper use of the Roller Tension System.
§ ATTENTION – Do not make any adjustments to the tensioning system of
the machine. The tension has been preset and will not need adjustment
unless otherwise directed by MUNCH Machine.
Coupler
The green Flex Element within the coupler assembly is a wear component that reduces
wear on the drive train components. This Nylon Cover and Flex Element should be
removed and inspected prior to high use scenarios or inspected monthly in the event of
perpetual harvest. With high wear the green Flex Element should be replaced. One
additional Flex Element is included with each machine, and additional Flex Elements can
be purchased from MUNCH Machine Customer Service. It is recommended to keep a
spare Flex Element on hand at all times.
To remove the green Flex Element, back the two screws partially out of the Black Nylon
Cover. Next, slide the Nylon Cover off, taking note of the alignment between the Nylon
Cover screws and the holes in the Flex Element. The green Flex Element can then be
removed by finding the split and then peeling the teeth out of the steel 5R Couplers. To
reinstall work backwards through these steps, being mindful of the alignment between
the Nylon Cover screws and the holes in the Flex Element.
While inspecting the Flex Element ensure that the black Nylon Cover is in good
condition. Once installed, align the Nylon Cover with the Flex Element and ensure the
screws are fully seated in the black Nylon Cover.
§ CAUTION – Do not run the machine without a complete Coupler
assembly.
