Points to be observed with separate compressed air lines
Lubrication with tool oil.
Air tools that must not be lubricated can be damaged.
➤ Blow any residual oil out of the line before connecting such an air tool.

Low temperature equipment options
Special equipment is provided for operation in extremely low temperatures.
This equipment assures trouble-free operation in ambient temperatures from -13 °F to 122 °F.
The electrical system will reliably start the engine at ambient temperatures to -4 °F.
Coolant pre-heating:
The engine coolant can be pre-heated to improve starting under cold conditions.
The power supply to the coolant pre-heater takes place via a separate network connector. A flexi‐
ble power cable (supplied) connects the machine's power plug to the user's power socket.
The coolant pre-heater works according to the principle of self-circulation.

The ideal coolant pre-heating period is 2-3 hours before the machine is started. A pre-heating peri‐
od of more than 3 hours is not necessary, as the maximum effect has already been achieved within
this period (thermal balance).
Continuous operation of maximum 6 hours must be followed by a rest of approximately 3 hours.

Options for operating in fire hazard areas
Diesel engines represent a potential source of ignition in environments with concentrations of gas,
vapor or dust, and may cause major fires with disastrous consequences for people, the environ‐
ment and production.
