- Turn off the motor before adjusting, lubricating, or performing any maintenance job on the
machine. Never try to perform any repairs when machines are on.Always pay attention!
- Check to see if there are any tools or objects on it, before turning on the machine.
- Look around the machine before turning it on. Keep animal and spectators at a safe distance,
away from eating areas. Be especially careful of children.
- Wear personal operating equipment - PPE - when operating the machine. Prolonged
exposure to noise can cause hearing damage or loss. Wear hearing protectors and safety
glasses.
- Dress appropriately when operating the machine. Tie back long hair and do not wear clothing
which is too loose. Remove rings, chains, and other elements, which could get stuck in the
moving parts or mechanisms.
- Never try to open the machine when it is operating.
- Never touch the pulleys or belts when the machine is turned on. Keep your distance from
moving parts.
- Keep the safety adhesive labels in good condition and legible. Replace them whenever
necessary.
- Keep all the protective shielding in its proper places and do not operate the machine without
it being installed.
- People must not remain on any part of the machine when it is operating.
- Turn off the motor and wait until all the parts are completely motionless, whenever, it is
necessary to get on the machine to perform any adjustment or repair.
- Never try to clean or remove remaining products, straw etc., when the machine is turned on.
Turn off the motor and wait for all the parts to stop moving before cleaning any part of the
machine.
- Never leave the machine operating and leave the area. Always turn off the motor before
leaving the working area.
- Keep the surrounding areas free and unobstructed, so the operator can move safely around
the machine and the product being processed.
- Lower the machine completely to the ground before performing any maintenance,
lubrication, or adjustments. If it is necessary work on the machine when it is lifted hydraylically,
make sure it is supported securely. Hydraulic mechanisms can move without any warning or
due to leakage and causa an accident.
- Never place the machine on cement blocks, hollow bricks, or other supports which can be
crushed from the effects of loads during long periods of time.
- Never work under a hoisted machine raised just on a jack, always put a secure support under
it.

TECHNICAL MANUAL OF OPERATION - JF 15D
- If you notice any abnormal operation: vibrations, strange noises etc., immediately turn off the
machine. Check and eliminate the cause, before turning it on again.
- Moveable parts and components, due to inertia, they continue moving after the machine
stops operating. Before touching any part, disconnect the actuation source, look, and listen to
see if there is any evidence of movement. Only touch a part if you are sure if is motionless.
Always pay close attention!
- Before starting the electrical installation of the motor, make sure the local electricity is turned
off.
- The installation of electric motors must be performed by a qualified electrician. The
dimensioning of the cables and the utilization of starting devices must comply with currently
applicable safety standards.
- There must be enough space around the machine for circulation to keep it permanently
unobstructed and to allow for safe movement of the operator and the product being
processed.
- We recommend installing the machine in a flat location, free of oil, grease, holes, protected
from the sun and rain. Contact with water increases the hazard of electrical shock.
- Never operate the machine inside closed locations and without ventilation, the gases
released from the motor (diesel or gasoline) are toxic and highly harmful to health.
- Be prepared in case of an accident. Keep a first-aid kit on hand and easily accessible. Know
how to use it.
- Do not use this equipment for applications which are not mentioned and considered
unacceptable in the manual and not authorized by the manufacturer. Making adaptations or
using after-market parts can compromise the operation, be dangerous to the safety of the
operator, and invalidate the guarantee.
- Follow the safety recommendations and pay attention. Lack of attention while operating can
cause accidents.

Cambio de los martillos
Lubricación
Los martillos (A) poseen 4 caras dentadas para ser cambiadas a medida que se desgastan.
Para cambiar la cara o substituirlos, proceder de la siguiente manera:
1- Cortar las trabas (B) de los bujes de los martillos.
2- Retirar los bujes de los martillos (C), observando el posicionamiento correcto de los anillos
separadores, y tomándose el cuidado de no mezclar los juegos de martillos, pues eso
perjudicaría el balanceo de la máquina, provocando vibraciones.
1- Los únicos puntos de lubricación son los cojinetes
de rodamientos (D).
2- La lubricación debe ser hecha semanalmente.
Lubricar con el auxilio de una engrasadora los
rodamientos de los cojinetes (D), con grasa especial
para rodamientos, a base de jabón de lítio,
clasificación NLGI 2 EP. Ejemplo de grasa: LUBRAX
LITH-2.
Antes de lubricar, limpie bien las engrasadoras para
evitar la contaminación de la grasa.
Substituya engrasadoras dañadas.
La lubricación es más eficiente cuando es hecha al
final del período de trabajo, pues la grasa fluye mejor
mientras la máquina todavía está caliente.

Remoción de las cuchillas
Afilado de las cuchillas
Regulado de la contracuchilla
MANUAL TÉCNICO DE OPERACIÓN - JF 15D
Para remover las cuchillas (A), basta retirar los tornillos (B), junto con las respectivas arandelas.
1- El afilado de la cuchilla debe ocurrir siempre que el corte estuviere gastado.
2- Debe ser hecha solo de un lado del corte de la cuchilla, procurándose mantener la misma
inclinación del corte original.
3- Se debe procurar retirar la misma cantidad de material en cada cuchilla, para no perjudicar
el balanceo.
4- Las cuchillas deberán ser substituidas cuando no posibilitaren más afilado.
Para regular la contracuchilla, proceder de la siguiente manera:
1- Soltar las tuercas de los dos tornillos (C).
2- Desplazar la contracuchilla (D) hasta que la distancia entre cuchilla y contracuchilla
(medida M de la figura abajo) sea de aproximadamente 0,5 mm.
3- Reajustar las tuercas (C).
Nota:
Se debe substituir la contracuchilla cuando estuviere gasta y reajustarla
periódicamente.

Application
Actuation
Operation
JF Máquinas forage chopper can be used for dried products as well as for fresh products.
Thus, for such products as sugarcane, grasses, branches, roots, tubers and forages used for
daily animal feed, as well as for shredding dry products, as corn kemels, corn with the leaves
and cob, dried rice plants, corn stalks, dried cereals, cereal straw, and others, used for
preparing animal feed and foods.
Using this machine for products, such as soybeans and rice, will wear out the components
prematurely, due to their abrasive nature. So, for this reason, if the user using the machine for
such products then the user will lose the guarantee and then, the user will be liable for the
results.
The JF 15D can be driven by motors (electric, diesel or gasoline) and by tractors. The
accessories for coupling include the stands, pulleys and belts and are supplied when ordered
by the customer.
DRY PRODUCTS:
The product, such as grains or cereals, is placed in the
intake chute or in the hopper, and drains into the blades,
which crack them and them it flows inside of the
machine, where it is hit by the hammers. Then it is
filtered through the sieve.
The granulation of the product depends on the sieve
used. This product can leave the machine through a
cyclone or just by draining into the lower outlet.
FRESH PRODUCTS:
The product is placed in the intake chute and drained
until it comes to the blades, which are responsible for
cutting it. The product can come out from the lower
chute as well as the upper outlet.

11
The JF 15D requires some accessories for coupling to electric motors, such as bases,
pulleys and belts.
The machine and the motor are installed on a one-piece base.
JF Máquinas stand is equipped with special rubber feet which do away for the need of any
other base.
1- Electric installation for the power source:
This must be done based on the technical specifications, considering such factors as:
distance, correct cabling distance, as well as breaker switches and safety devices.
2- Electric motor installation:
This must comply with the technical based on the motor specifications. For motors over 5 hp
power, we recommend installing a triangle-star switch for turning on the actuation.
