2. General description
This manual refers to the following models:
LM-10/P, LM-22/P, LM-82/P
Meat grinders are designed to grind fresh meat quickly, producing a good quality grinding result
and they have been constructed following the KT product development methods. The operation
of the grinders is quiet. They are easy to dismantle for cleaning purposes.
Models LM-10/P, LM-22/P and LM-82/P start/stop buttons, as well as emergency stop switch
are located in the front of the grinder (Picture 1: No. 1a, 1b, 1c). The starting switch also
incorporates an undervoltage circuit breaker to prevent unintentional restarting after the power to
the machine has been cut off.

3. Unpacking
The meat grinder may be stored in the cold store. All models must be thoroughly cleaned before
usage. See chapter 6.1 for the recommended cleaning agents.
The meat grinder is delivered with feeding equipment dismantled. The installation of the feeding
equipment is dealt in chapter 6.3. If the grinder or its package has been damaged during the
transportation, contact your retailer or the manufacturer.
The meat grinder can be lifted from the pallet or from its packaging by hand. The weight of the
grinders are mentioned in chapter 1.1. Utmost care must be taken when lifting the grinder.
4. Installation
4.1 Location
The meat grinder must be installed on a steady table, which must be large enough so the grinder
fits completely on the table.
A base for the table is provided as an optional equipment. The base is equipped with wheels. The
front two wheels may be locked, while the two back wheels are fixed. The wheels make the
moving of the machine easier. When using the optional base, the grinder must be attached to the
base with a bolt which is included in the base.
The location of the grinder must be away from corridors and doors. The location must have
adequate light. For the safety of the user, the surface of the floor must be non-slippery.

4.2 Electrical connection
Please note
1. Ensure that the voltage corresponds with the voltage marked on the rating label.
2. The machine must be CORRECTLY EARTHED.
3. Only an authorized electrician may connect the electrical supply to the machine and carry
out the servicing work.
4. Ensure that the electrical supply has been disconnected before any electrical connections
are made, or maintenance or adjusting work is carried out.
4.2.1 Direction of rotation
Before using the machine, check the direction of rotation with the feeding equipment
dismantled.After start-up, the machine's blade should rotate counter-clockwise when observing
it from the front (Picture 2). If the direction of rotation is incorrect, ask an authorized electrician
to change the direction of rotation.

5.1 Safety
5.1.1 Safety measures
The importance of following safety procedures in the operation of industrial meat grinders
cannot be over-stressed. Meat grinders are capable of inflicting bodily damage to operators.
However by using common sense and being careful, as well as following all safety measures in
the operation of meat grinders, the operator will get the best possible performance out of this
versatile machine, and minimize the of accidents.
Your personal safety is more important than the quick operation of the machine.
It is recommended that only authorized persons who have received the correct training in the
operation of industrial band saws may operate them. They must also be aware of the danger
factors and safety measures.
PLEASE NOTE
All safety instructions in this manual are the manufacturer's recommended practices. Local safety
regulations and measures must always be observed.
Do not use this machine to anything else, than the purposes mentioned in this manual. The
diameter of the holes in the last plate towards the outlet shall be less than 8 mm. It is
forbidden to use hole plates with larger holes. The last plate towards the outlet is not
allowed to be ground thinner than 5 mm thickness.
5.1.2 Before use
Before starting up the meat grinder, the operator must:
1. DISMANTLE the blades and feeding screw (Instructions for cleaning: chapter 6)
2. CHECK the direction of rotation of feed screw (counter-clockwise).
3. CHECK that the meat tray is firmly in place.
4. CHECK that the blade and hole plate to be mounted in the machine are used in pairs.
5. CHECK that the blade and hole plate are correctly mounted in the grinder housing.
6. CHECK that the edge of the hole plate remains 2-4 mm outside the housing (LM-
10/P & LM- 22/P), or the edge of the distance ring remains 2-4 mm outside the
housing (LM-82/P).
7. CHECK that the blades in the assembly are always mounted in the same order (LM-82/P)
8. CHECK that the entry nut is not too tight, in order to prolong the lifespan of the blade
assembly.
9. ENSURE that the diameter of the holes in the last plate towards the outlet shall be less
than 8 mm.

5.1.3 During use
Keep a check on the quality of the product. If the product does not flow out properly or if it has a
porridge-like consistency, check the blade and the hole plate. Worn components should be
replaced. See chapters 6.2 and 6.3, dismantling and reassembly of the blade assembly
5.1.4 After use
1. STOP the machine by pressing the black stop button (Picture 1, No. 1b).
2. DISCONNECT the power supply.
5.2 Starting up
Provided that all the conditions in chapters 5.1.2 are fulfilled, the grinder may be started by
pressing the white start button (Picture 1, No. 1a).
5.3 Stopping
The meat grinder may be stopped by pressing the black stop button (Picture 1, No. 1b) or IN AN
EMERGENCY by pressing the EMERGENCY STOP BUTTON (Picture 1, No. 1c). The
machine is equipped with an undervoltage circuit breaker, so that it will not start up
unintentionally when the power supply is restored following a power cut or disconnection of the
machine from the power supply.
5.4 Grinding
•Feed the meat to the grinding house by using the feeding hammer provided with the machine.
•Do not push your fingers to the feed intake.
•Let the grinded product fall freely to the tray.
•Do not try to push your fingers into the holes of the hole plate.
•Do not drop foreign objects into the grinding house.
6. Cleaning and maintenance
Clean the grinder thoroughly after usage. At first, remove the plug from the wall socket. Remove
the meat tray by lifting it upwards. Remove the hole plate, blade and feeding screw from the
grinding house (see chapter 6.2. Dismantling the blade assembly).
The parts removed from the grinder should be washed using warm water, a suitable cleaning
agent and a cleaning brush provided with the machine The parts should also be disinfected. The
feed housing is dried after washing and wiped over using a suitable alimentary oil. The outside
of the grinder should be wiped using a suitable cleaning agent and then dried. DO NOT USE
PRESSURIZED WATER.

appropriate manner.
6.2 Dismantling the blade assembly
Loosen the nuts (Picture 3, No. 3) of the grinding house (No. 2) with a wrench (counter-
clockwise). Remove the entry nut (No. 4) by hand, by turning it counter-clockwise (see picture).
Remove the nuts (No. 3) of the grinding house, and then remove the grinding house. Push the
feed screw (No. 5) by hand from the backside of the grinding house, so that the feed screw and
blade assembly comes out from the grinding house. Remove the distance ring (LM-82/P, No.
