GENERAL INFORMATION
Operating the machine in cold weather
NOTICE: before operating at temperatures below -1 °C
(30.2 °F), operate the engine for approximately 15 min at
a speed below 1200 RPM to warm the oil up to the normal
operating temperature.
Fuel
Refill the fuel tank after each working day to prevent the
formation of condensation and the entry of water into the
fuel system.
NOTE: use low sulfer diesel fuel ONLY.
To prevent the formation of crystals -2 °C (28.4 °F) use
a low temperature fuel or mix a protective fluid with your
fuel.
Lubricating oil
Select oil viscosity (SAE grade) according to ambient tem-
perature before starting engine.
Increase oil change frequency when operating below -10
°C (14 °F).
Engine oil
The engine oil must have a viscosity corresponding to the
ambient temperature.
Coolant
It must have characteristics corresponding to the ambient
temperature.
Battery
Efficient cold starting requires that battery is sufficiently
charged.
Warm up the batteries approximately up to +20 °C (68 °F)
(disassembly and storage in a warm place) in order to be
able to start the engine at a temperature below 4 - 5 °C
(39.2 - 41 °F).
