INSTRUCTIONS FOR WINTER OPERATION
BEFORE THE COLD SEASON
Before the cold season begins, you should perform the following
preparatory measures to ensure troublefree operation also in the
winter months.
• The machine is provided with a aluminium radiator. There-
fore, the cooling system must be set to -34.6°F (-37°C) for
the whole year.
• Use oils with the prescribed viscosities which are suitable for
the cold weather to be expected in your region (see chapter
"Lubricants and Operating Agents").
• Fill up with winter diesel fuel. At low temperatures, paraffin
deposits of diesel fuel may block the filters and lines (see
chapter "Lubricants and Operating Agents").
• If the injection system, the starter, the battery and the gener-
ator are in perfect condition, it is ensured that the engine can
be easily started and that the machine can be operated trou-
blefree even in extremely cold weather. Let these important
components be checked at an authorised garage before the
winter starts.

haviour of the engine, especially at low temperatures. Let
the compression pressure be measured at an authorised
garage.
• If the speed is continuously increased, the starter may re-
main switched on until the engine finally starts up.
• Let the engine warm up with increased idle speed for some
minutes before starting to work. During the warm-up phase,
operate the hydraulics devices several times without load.
• Add a standard antifreeze to the water in the windshield
washer assy. If required, add 25 vol. % of alcohol (spirit) to
the water.
AFTER OPERATION
Realise the following actions to make sure that the machine can
be started the next time without problems:
• Remove mud and water from the car body. This prevents
that sealings are damaged due to freezing.
• Park the machine on hard and dry ground. If this is not pos-
sible, you must park the machine on wooden planks. The
planks prevent that the wheels are freezing to the ground.
• Drain off collected water from the fuel system.
• The battery capacity drops clearly at low temperatures.
Therefore, dismount the battery in frost periods and store it
in a warm place. Re-install it the next morning, before start-
ingtowork.
