Breathing air filter
Compressed air from an oil-injected compressor must not be used for breathing air.
Dried compressed air must be filtered to remove all contaminants, such as fine dust and oil, as well
as odours, before it can be used for breathing. To achieve this, the compressed air is passed through
a combination of microfilter and activated carbon filter.
The breathing air connector is specially marked; it is located separately on the compressed air dis‐
tribution block.
DANGER
Danger of fatal injury from breathing arrest!
The filter does not remove CO/CO

, methane or other toxic gasses or vapours.
➤ Never use the machine in enclosed spaces, only in the open.
➤ Clean inlet air with no damaging contaminants.

Special equipment is provided for operation in extremely low temperatures.
This equipment guaranties trouble-free operation in ambient temperatures from -25 °C to +50 °C.
The electrical system starts the engine without problem at ambient temperatures down to -20 °C.
Coolant pre-heating
The engine coolant can be pre-heated to improve starting under cold conditions.
A separate mains power connection provides power to the coolant pre-heater. A flexible power cable
