INSTALLATION
7.1
UN-PACKING
Whenever possible the chopper should be transported to the installation position
in the packaging provided to avoid damage. Do not use a sharp knife to cut into
the box as damage to the machine may occur. Check for possible shipping
damage. If the unit is found to be damaged, save the packaging material and
contact your nearest Hobart sales office. Before installing, verify that the
5
electrical service agrees with the specifications on the rating plate located on the
front panel of the chopper below the drive hub.
With the machine in the vicinity of its final position, remove carton from around
the machine. Remove the four bolts holding the machine to the skid. Unpack the
chopper attachment carton.
After removing the skid, screw the threaded studs of the four legs (provided) into
the tapped holes in the four corners of the base. The rubber feet on these legs
cushion the machine. Under normal operation, the machines does not need to be
bolted down.
7.2 LOCATION
The chopper is not suitable for outdoor installation and must not
Be installed where a water jet could be used for cleaning. The
chopper must only be operated by trained staff and must be installed
in a area where the use and maintenance is restricted to trained
personnel
The chopper must be installed on a horizontal flat surface level to a
minimum of 1mm in a 1 metre side to side and front to back. Select a suitable flat
surface that can support the weight of the chopper and feed pan when full (refer
to table 1 for weights and page 5 for dimensions).
7.3 ELECTRICAL INSTALLATION
The electrical installation of the chopper must conform to the local
electricity board regulations. When installed in the United Kingdom
the installation must be in accordance with the current edition of the
IEE regulations for electrical equipment in buildings and the
Electricity at work act. A competent person must carry out the
electrical installation.
The machine is rated 230 Volts / 50 Hertz / 1 Phase. The 1.8 metre long flexible
power cord is IEC rated and should be fitted with a 10 Ampere grounding-type
plug. A properly grounded 10 Ampere circuit with proper fuse or circuit breaker
protection should be provided with a mating-type receptacle, convenient to the
final location of the machine.
7.4 ELECTRICAL CONNECTION
Refer to the wiring diagram supplied with the chopper on the rear housing panel.
6
8.0 COMMISSIONING AND OPERATING INSTRUCTIONS
8.1 OPERATOR TRAINING
Take time to explain the correct operation and cleaning of the chopper to the
users, referring to this manual. Leave this manual with the operator and explain
that it is important to use it for further reference.
8.2 USING FOR THE FIRST TIME
The chopper must be cleaned and sanitized before use. Refer to Cleaning and
Sanitizing, pages 10.
8.3 COMPONENT IDENTIFICATION:
CHOPPING END
Figure 1
7
8.4 ASSEMBLY OF CHOPPING END AND FEED PAN
Make sure the drive hub and socket are clean and clear of any obstruction. Insert
the socket end of the cylinder into the drive hub with a slight twisting motion
toward the left. The chopper cylinder stop pin in the attachment will contact the
side of the hole that receives it. Tighten the thumb screw to secure the chopper
cylinder in place ( Fig. 1).
Removing the chopper cylinder requires loosening the thumb screw three
complete turns. The thumb screw should never be removed. Slide the worm into
the cylinder and rotate it until the square shank of the worm locks into the hub
drive. Install the knife on the end of the worm with the cutting edges out, followed
by the grind plate (Figs. 1,2). The notch on the grind plate aligns with the pin in
the bottom of the chopper cylinder. Thread the adjusting ring on the chopper
cylinder hand tight. Install the feed pan and feed stomper.
CAUTION: The knife and plate depend on meat for lubrication. Therefore, the
chopper should never be operated without meat.
9.0 OPERATION
9.1 CONTROLS
Main power switch:
I (green) ----- Push turns chopper motor ON.
0 (red) ----- Push turns chopper motor OFF
9. 2 CHOPPING
Cut the meat into strips.
Turn the machine ON.
Feed the meat into the chopper using the feed stomper only as needed.
If the strips are cut to the proper size, they will feed without assistance from the
stomper; allowing both hands of the operator free to feed the meat. When
running meat through the chopper a second time, more speed is attained by
feeding small quantities at a time rather than by trying to force large amounts
with the feed stomper. The feed pan should always be kept in place on the
cylinder. It not only makes regular feeding easy, but it keeps the chopper
attachment ready for immediate use. The fineness to which the meat is cut is
governed by the size of the holes in the perforated Grind Plate, not by the tension
put on the Adjusting Ring. Do not tighten the Adjusting Ring more than hand
tight. Between uses, remove the entire chopper end and feed pan and place
them in the refrigerator for re-use; or, clean and sanitize, if required.

10.0 CLEANING AND SANITIZING
Disconnect the mains electricity supply before cleaning or
servicing this machine.
Remove the following parts for cleaning; Feed Pan, Adjusting Ring, Grind Plate,
Knife, Worm, and Chopper Cylinder.
The chopper must be thoroughly cleaned and sanitized after installation and
before being placed into service.
Cleaning Supplies (Not Provided)
Recommended cleaning and sanitizing supplies include:
• A 12" handle nylon brush that will slide through the cylinder
• A two compartment pail for cleaning solutions
• A pail for sanitizing solution
• A scrap pail
• Clean cloths
• A spray bottle
NOTE: When using detergents and sanitizers, always refer to the chemical
manufacture’s safety data sheet for hazard, handling, and first aid information.
Wear suitable gloves and eye / face protection.
Prepare a hot detergent solution in one side of the two compartment pail. Fill the
other compartment with warm potable rinse water.
Mix a sanitizing solution by adding one tablespoon of sodium hypochlorite bleach
(5.25%) to one gallon of water in a pail. This makes a 200 ppm solution. Use this
solution to fill the spray bottle as well as the pail for sanitizing.
Thoroughly clean and sanitize the feed pan, feed stomper, chopper cylinder
assembly, worm assembly, knife, plate, adjusting ring and machine housing.
Refer to Fig. 1 for component identification.
NOTE: After cleaning, apply a light coat of food grade mineral oil to the cylinder,
adjusting ring, knife, plate and worm before reassembly.
To reassemble, refer to ASSEMBLY----- page 8

11.0 MAINTENANCE
WARNING: UNPLUG CHOPPER POWER CORD BEFORE
CLEANING, SERVICING OR REMOVING PARTS. REPLACE PARTS BEFORE
USE.
MACHINE CLEAN UP
The machine should be thoroughly cleaned at the end of an operating day or
after being idle for an extended period of time. Refer to CLEANING for proper
procedure (previous section).
HUB AND CYCLINDER DRAIN
Hub Drain
A drain slot in the trim washer allows any meat juices to drain from the hub. This
slot should be inspected periodically to make sure that it is free of obstructions. A
small brush can be used to remove any material which may have accumulated.
Cylinder Drain
A drain hole at the bottom end of the cylinder allows any meat juices to drain.
This hole should be inspected periodically to make sure that it is free of
obstructions. A small wire can be used to remove any material which may have
accumulated.
AIR INTAKE
Under normal operating conditions the motor air intake screen, located in the
base of the chopper, will need little or no attention. However, in some
installations where sawdust or other foreign materials are present in the air, this
intake screen may become partially or completely covered. Where an adverse
dust condition does exist, periodically check the screen and wipe clean with a rag
or brush as required.
STORAGE
The chopper should be completely cleaned and covered with a towel or other
suitable cover when it is not to be used in the immediate future.
