SAFETY PRECAUTIONS
Read carefully these instructions on safety and use before starting to operate the combine. Time spent in becom-
ing familiar with the instructions now, will save you money or may even spare you from injury.
Before accepting the delivery of the combine, make sure it conforms to the delivery contract.
Do not t the combine with any accessories not approved of by the Manufacturer. The Manufacturer of the Com-
bine is not responsible for any damage or injury caused by such accessories either to people or property.
1. TRANSPORTATION ON A VEHICLE OR BY RAIL
Make sure you know the measurements and weights of the combine and the transporter. When driving the com-
bine on the road, comply with the relevant statutory trafc regulations. Use increased tyre pressure (2-2.5 Bar) to
improve stability.
Fix the combine securely in the transporter. For road transport, lower the cutting table fully or remove it.
2. DRIVING IN TRAFFIC
When driving on public roads, comply with the relevant
statutory trafc regulations. Remember that the com-
bine has rear-wheel steering.
Brake pedals must be latched together. Test brake
functions before driving on the road. Brake smoothly
as the rear wheels of the combine easily rise from the
ground when applying the brakes violently. The thresh-
ing equipment must be disengaged, the straw dividers
removed and the unloading pipe locked for road trans-
port.
On combines with the Premium Plus cab, the safety
switch on the instrument panel shall be depressed.
(The switch is released to its top-most position by turn-
ing the knob clockwise.)
The knife guard and the front warning signs shall be
tted onto the table. (Fitting of the front warning signs
in accordance with the enclosed illustrations.)
The front and rear lights and the rear-view mirrors shall
be correctly aligned.
Never drive downhill with the gear in neutral. Never
carry passengers on the machine.
Never use the combine for transporting goods.
Always have the grain tank empty when driving on the
road.
3. THRESHING
Get familiar with the structure of the combine by stu-
dying the manual before starting threshing.
Wear appropriate clothing.Avoid loose clothing that
may get entangled in moving parts. Use of hearing
protectors is recommended.
Make sure the protective guards are properly attached
and in good condition.
When working with combine harvester it is advisable to
keep the cabin doors closed.
Sound the signal to warn people around the combine
before starting the engine.
Adjust the rear-view mirrors before starting to ensure
good visibility of the road or the working area behind.

EXIT
Never use the combine for anything but threshing.
Manual feeding of crops onto the cutting table is pro-
hibited.
Before starting, particularly reversing, make sure that
everybody nearby is aware of your intentions.
Test the brakes as soon as you start, and stop immedi-
ately if the brakes or steering operate defectively.
Never adjust the seat or steering wheel while driving.
Never leave the cab while the combine is moving.
Never leave the engine running unattended.
Do not open any guards with the engine running.
Do not climb on top of the grain tank or the straw walk-
ers with the engine running, and do not let anybody
else do it either.
Beware of the cutting mechanism and the rotating
chopper knife.
Keep in mind that with the chopper rotating, there is a
20 m no-access danger zone behind the chopper.
Drive carefully on hillsides; the combine may overturn,
particularly with the grain tank full.
The combine cab is no safety cab.
THE RIGHT-HAND SIDE DOOR MAY BE USED AS
AN EMERGENCY EXIT. PULL UP THE HANDLE,
AND OPEN THE WINDOW. Fig. EXIT
Note the recommended safety distances when thresh-
ing under power lines.
Stop the engine before cleaning or servicing the com-
bine.
Stop the combine and the engine immediately if there
is an alarm or any abnormal sounds or smells. Find out
the reason for them, and solve the problem before car-
rying on with threshing.
Support or lock the cutting table and the reel before
going beneath them.
Never clean the combine without proper equipment.
When leaving the combine, lower the cutting table,
lock the parking brake, stop the engine and remove
the ignition key.
SAFETY DISTANCES WHEN THRESHING
UNDER OPEN-WIRE POWER LINES
The minimum clearance between the combine and
power lines with voltage must be in accordance with
the enclosed illustration, in which the danger zone is
darkened.
Low-voltage power lines, g. A3 (240/400V) can be
distinguished from high-voltage line, g. A4...A5 (over
1 kV) by the smaller insulators and the fact that there
are usually 4 low-voltage lines.
In case the height or voltage of the power line is dif-
cult to estimate, the Electric Company shall be con-
sulted.

In Case of an Accident
If there is an accident despite all precautions, keep
calm and consider carefully what to do. First try to re-
verse the combine away from the power line. If there
are other people near, ask them to check that the com-
bine is not stuck in the line.
If the combine is just leaning against the lines, try to
drive it away from them. Follow the advice from the
people nearby. Due to their own safety, they shall stay
a minimum of 20 metres away from the combine touch-
ing the power line.
If the combine cannot be driven off, and you have to
leave the combine, jump down with your feet together
in order not to touch the combine and the ground
simultaneously. Do not make yourself a conductor
through which electricity can pass; the real danger lies
in touching the combine and the ground simultane-
ously. Get away from the combine jumping either with
your feet together, or with only one foot on the ground
at a time.
Otherwise the electric eld on the ground may create
a fatal electric current between your legs. You will be
safe at a distance of 20 metres from the combine.
Beware of broken power lines lying on the ground.
A combine touching a power line may catch re. Leave
the combine immediately if smoke starts coming from
the tyres.
Make sure the combine will be guarded at a safe dis-
tance. Do not try to get on the combine even if the
power in the power lines may seem to have gone off.
Remember that open-wire lines never have a ”blown
fuse”, but they are always dangerous unless made
dead by an electrician. Even if the power went off, it
might come back on in a while due to technical rea-
sons. This may be repeated several times.
Contact the Electric Company and inform them about
the exact site of the accident. By doing this, any risk
can be eliminated and the fault repaired.
Ask the Electric Company for advice and follow it. In-
form them about any contact with power lines even if
there was no actual damage.

When servicing the hydraulics, be aware of the high pressure in the system. Make sure there is no pressure in
the system or in the pressure accumulator before disconnecting the connectors.
Never use over-sized fuses; they involve risk of accident.
Never start the combine with anything but the ignition key.
When retting a wheel, tighten the xing screws to the correct torque.
Attach accessories such as the trailer using the appropriate equipment.
Tow the combine only from designated points.
5. THE LAWS AND REGULATIONS
Combine harvester is a complex device, and dangerous if misused. User manual must always be preserved with
the machine at the place reserved for it and if needed, new drivers should be instructed to operate the machine
Different countries have different safety at work and trafc regulations. Get to know the existing regulations of
your area.
4. REPAIR AND SERVICE
Always keep the combine in good condition.
Check the condition of fast moving parts daily. Pay
special attention to the transmission mechanism and
the rotating chopper knives. Replace defective parts
before they become dangerous.
Clean, repair and service the combine with the trans-
mission and engine off, the ignition key off the ignition
switch and the master switch in its off position.
Disconnect the negative battery cable before repairing
the engine or any electrical instruments.
Do not use inappropriate tools to connect and discon-
nect the battery.
Do not make an open re or smoke near the battery.
Handle the battery acids with care.
Do not add air in the tyres without a pressure gauge
due to risk of explosion.
Do not add coolant with the engine running.
Do not remove the radiator cap from an overheated
engine.
Do not refuel with the engine running.
Beware of hot surfaces of the engine and exhaust pipe.
Do not smoke while fuelling.
Do not adjust the hydraulic working pressure without a
pressure gauge due to possible damage to the hoses.

This symbol in the manual refers to a special risk involved in taking a certain measure, due to which extra
caution shall be practised.
6. FIRE SAFETY
Two factors are needed to start a re: ammable material and ignition; oxygen is always available.
Threshing generates a lot of light and highly ammable dust. Therefore it is important to clean the combine on a
regular basis, and the engine compartment daily.
Oil and fuel leaks increase the risk of re. Repair any defects immediately.
High temperature near the exhaust pipe makes the area re-prone. A re may also be caused by a short circuit in
the electric system, slipping of an overloaded belt, a damaged bearing or overheating of the brakes.
Make sure there is at least one 6-kilo class AB re extinguisher located in its marked place on the combine at all
times.
In particularly dry and dusty circumstances another similar extinguisher is to be placed near the engine compart-
ment.
