1. INTRODUCTION
1. INTRODUCTION
INTENDED USE
JF disc mowers are developed for agricultural work. They should only be connected
to tractors and driven by the PTO of the tractor.
The disc mowers are solely intended for:
Cutting on the ground of natural or planted grass and stem crops for
animal feeding purposes
It is assumed that the work is performed under reasonable conditions, i.e.
that the fields are cultivated normally and to a reasonable extent kept clear
of stones and foreign matter.
Any use beyond this is outside the intended use. JF-Fabriken A/S is not responsible
for any damage resulting from such use, the user bears that risk.
If changes are made on the machine and its construction without permission from JF-
Fabriken A/S, JF-Fabriken A/S cannot be held responsible for any damage resulting
from this.
Intended use, of course, implies that you observe the prescriptions in the instruction
manual and the spare parts book, use original spare parts and contact an authorised
workshop, in so far as it is necessary.
The following safety instructions as well as common rules concerning technical
safety, working practices and road safety must be observed altogether.
The disc mowers should only be used, maintained and repaired by persons who,
through relevant instructions and after reading the instruction manual, are familiar
with the machine in question and, in particular, are informed of possible dangers.

1. INTRODUCTION
SAFETY
The safety of persons and machines is an integral part of JF-Fabriken's development
work. We wish to ensure the safety of you and your family in the best possible
way, but this also requires an effort on your part. However, damage can occur as a
consequence of misuse and insufficient instruction.
A mower cannot be constructed in such a way that it guarantees the full safety of
persons and at the same time performs an efficient piece of work. This means that it
is very important that you as user of the machine pay attention and use the machine
correctly and thereby avoid exposing yourself and others to unnecessary danger.
The machine demands skilled operation, which means that you should read the
instruction manual before you connect the machine to the tractor. Even though
you have been driving a similar machine before, you should read the manual - this is
a matter of your own safety!
You should never leave the machine to others before you have made sure that they
have the necessary knowledge to operate the machine safely.
DEFINITIONS
The safety decals and the instruction manual of the machine contain a line of
safety notes. The safety notes mention certain measures, which we
recommend you and your colleagues to follow as to increase the personal
safety as much as possible.
We recommend that you take the necessary time to read the safety instructions and
inform your staff to do the same.
In this instruction manual this symbol is used with reference to
personal safety directly or indirectly through maintenance of the
machine.
CAUTION: The word CAUTION is used to ensure that the operator follows the
general safety instructions or the measures mentioned in the instruction
manual to protect himself and others against injuries.
WARNING: The word WARNING is used to warn against visible or hidden risks,
which might lead to serious personal injuries.
DANGER: The word DANGER is used to indicate measures which, according to
legislation, must be followed to protect oneself and others against
serious injuries.

1. INTRODUCTION
GENERAL SAFETY INSTRUCTIONS
The following is a brief description of the measures, which should be observed by the
operator.
Transport
1 Always lower the cutting unit to the ground or activate the transport safety
device when parking the machine.
2 Never stand between the tractor and the mower during connection and
disconnection.
3 Always drive with the statutory lights and safety marking during transport on
public road and at night.
4 Always use transport safety devices and stop valves for hydraulic cylinders.
5 Limit the transport speed to maximum 30 km/h if the machine has not been
marked with another maximum speed limit.
WORKING
6 During work never wear loose clothes which can be pulled in by the moving
parts of the machine.
7 Use hearing protectors if the tractor has not been silenced sufficiently.
8 Make sure that all guards are intact and have been mounted correctly.
9 When connecting the PTO drive shaft, check for 540/1000 rpm.
10 Never start the tractor until all persons are safely away from the machine.
11 Do not stand near the machine while it is working.
12 Stop the machine if children are near.
13 Never use the machine for other purposes than what it has been constructed
for.
14 Do not stand near – or try to lift a guard – until all revolving parts have stopped
moving. This also applies when adjusting the machine!
15 Always disengage the PTO drive shaft, activate the parking brake and stop the
tractor engine before you adjust the machine.
MAINTENANCE
16 Never work under the machine unless it is secured by means of stop blocks or
other mechanical securing device.
17 Always block the tractor wheels before working under the machine.
18 Always disengage the PTO drive shaft, activate the parking brake and stop the
tractor engine before you - lubricate the machine,
- clean the machine,
- disassemble any part of the machine,
- adjust the machine.
19 Remember to remove all tools before starting the tractor again.

1. INTRODUCTION
SAFETY –JF– MOWERS
CHOICE OF TRACTOR
Always follow the recommendations specified in the instruction manual of the tractor.
If this is not possible, technical assistance must be sought.
Choose a tractor with a suitable power on the PTO. To obtain full capacity under all
conditions, we recommend you to choose a tractor which has 15 kW more than the
informed minimum.
If the power of the tractor is considerably larger than that, the machine
should be secured against overload with a suitable clutch on the PTO.
If you have chosen a machine which is constructed for 540 rpm, you
should make sure not to use the wrong PTO by mistake. It is highly
dangerous to connect a machine intended for 540 rpm, to a PTO
delivering 1000 rpm.
Long-term overload may damage the machine and at worst result in
ejection of parts.
Choose a tractor with a suitable own weight and track width so that it can drive
steadily on the ground. Also make sure that the link arms and towing hook of the
tractor are intended to carry machines with the own weight in question.
To maintain full control of the tractor under all conditions, minimum 20 % of the own
weight of the tractor should be on the front axle. It may be necessary to use front
weights to fulfil this requirement.
Always choose a tractor with a closed cabin when working with a disc mower.
The hydraulic system of the tractor should deliver a pressure of maximum 210 bar.
PIGB-093X-06 GX 2402/2802/3202 SM-GX 2402/2802 SC 0410 9

1. INTRODUCTION
CONNECTION AND DISCONNECTION
Never stand between the tractor and the mower during
connection and disconnection.
An unintentional manoeuvre with the tractor may cause
serious injury.
Make sure that the PTO drive shaft has been mounted correctly, i.e. that the lock pin
is in mesh and that the support chain has been fastened at both ends.
The guard must be intact. If the guard is defective it must be replaced immediately.
Check that all hydraulic couplings are correctly mounted and tight and that all hoses
and fittings are undamaged before activating the hydraulic system.
When the tractor engine has stopped, make sure that there is no pressure in the
hydraulic hoses by activating the tractor hydraulic spool valves.
Hydraulic oil under pressure can penetrate the skin and cause serious infections.
You should always protect the skin and the eyes
against oil splashes. If, by accident, hydraulic oil
under pressure hits you, consult a doctor
immediately.
Make sure that no persons are near the machine when starting as there might be air
in the hydraulic system which might lead to sudden movements.
To ensure all the air has been expelled from the oil in the hydraulic cylinders, test all
the functions after the hydraulic connections are connected to the tractor. Especially
before driving on public road.
TRANSPORT
Never drive faster than the conditions allow, and maximum 30 km/h.
It is important to block hydraulic transport adjustments. An unintentional operation of
the cylinders may cause the machine to move and at worst hit cyclists or pedestrians.
This may also happen if there is air in the hydraulic cylinders or if there is a sudden
loss of oil from the hydraulic hoses.
Therefore, always check that mechanical transport safety devices are activated
before transport.
WORKING
Before working check blades and discs for cracks and other damage. Replace
damaged blades and discs.
Check periodically if blades and blade bolts are worn according to the rules in the
instruction manual. (See section on maintenance)
Loose stones and foreign matter in the field might get in contact with the revolving
discs and get thrown out again at a very high speed.
Therefore, all guards must always be correctly mounted and intact when you are
working with the machine.
In stony fields the stubble height should be adjusted to maximum (horizontal cutter
bar).
