INSTRUCTIONS FOR WINTER OPERATION 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. Insufficient compression pressure impairs the start-up be- 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- ing to work. 5-40
