Service measures every 6 months
The fire extinguishers shall be serviced every 6 months or more often if so stipulated in local
regulations.
Service measures every 1 year
If the harvester is equipped with an automatic extinguishing system, it shall be serviced as
instructed by the Manufacturer. See Servicing of the Fire Extinguishing System in the Opera-
tor Manual. In some countries, an annual official inspection of the machine is required in the
insurance terms and conditions.
Service measures every 2 years
1. Replacement of the AC drying cartridge
To guarantee faultless functioning of the air conditioning, the drying cartridge needs to be
replaced every 2 years.
2. Changing of engine coolant
The coolant shall be changed at least every other year to maintain its anti-corrosion proper-
ties. The cooling system is drained by opening the draining taps in the radiator water cell and
on the left-hand side of the engine at the rear and by unscrewing the cap in the expansion
tank. In order to drain the coolant from the heater cell, too, turn the thermostat to its maxi-
mum position.
Used coolant is problem waste, which shall be disposed of in an appropriate manner. Therefore
the draining taps are equipped with connectors to which a collection hose can be attached to
drain the liquid (fig. 48).

See further instructions in the engine manual.
The dual-functioning thermostat must not be removed to reduce the temperature, as this
would make most of the coolant circulate through the side circulation pipe, which reduces
cooling capacity.
On models equipped with an additional heater, air shall be bled from the heater when more
coolant is added. See the heater instructions!
