distance. Do not try to get on the harvester
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 reasons. 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. Inform them about any contact with power
lines even if there was no actual damage.

4. Repair and service
Always keep the harvester in good condition. Check the condition of fast moving parts daily.
Pay special attention to the transmission mechanism and the rotating parts in the harvester
head. Replace defective parts before they become dangerous.
Clean, repair and service the harvester with the transmission and engine off, the ignition key
off the ignition switch and main switch off.
The harvester head has many danger points. Read the harvester head manual to familiar-
ize yourself with them. On some models turning of the measuring wheel by hand makes the
knives, tracks and rolls close. This is extremely dangerous if the engine is running or there
is pressure in the hydraulic accumulator of the harvester head. Do not go near the harvester
head, particularly the knives, tracks and rolls, with the engine running.
Before welding, disconnect the battery cables, input cable of the diesel engine control unit (the
left hand side cable under the cover of the control unit attached to the engine), all the cables
to the PC processor, the cables of the measuring device head module (MCC) and the cab MCI
module, connector of the large wiring harness between the frames, the two large connec-
tors positioned on the rear frame that connect the frames and the central unit cables of the
optional fire extinguishing system.
Always have the earth cable of the welding set near where welding is done.
Do not use inappropriate tools to connect and disconnect the battery.
Do not make an open fire 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.
Beware of hot surfaces of the engine and exhaust pipe.
Do not refuel with the engine running.
Do not smoke while fuelling.
Do not adjust the hydraulic working pressure without a pressure gauge due to possible injury
and damage to the components.
When servicing the hydraulics, be aware of the high pressure in the system. Make sure there
is no pressure in the system, not in the head pressure accumulator, either, before disconnect-
ing the connectors.
Never use over-sized fuses; they involve risk of accident.
Never start the harvester with anything but the ignition key.
When refitting a wheel, tighten the fixing screws to the correct torque. Switching on the diesel
engine is allowed only when the hub is connected to the motor Do not make any such struc-
