Preheating system for engine and hydraulic oil (optional)

Preheating system for engine and hydraulic oil, function

The preheating system consists of heating elements for engine oil, engine coolant and hydraulic oil.

At low outside temperatures, the system facilitates starting of the engine and ensures that the hydraulic system reaches its operating temperature faster.

The preheating system is operated electrically with an external supply voltage. This voltage is available at a socket outlet at the service-station (tanklift) (Fig. 2-88:).

(The system has been set at the factory for a standard supply of 400 volts, threephase AC. Other voltages are available on request as well as socket outlets meeting other standards).

Switching the preheating system for engine and hydraulic oil on and off

Risk of an electric shock.

Check first:

Insulation of the socket outlet on the machine in good condition?

Insulation of the connecting cable in good condition?

Connect the system to the power supply only if the insulation of the components is in perfect condition.

Observe the national safety regulations to be applied in the presence of electric current.

Switch and pilot lamp are located at the switchgear cabinet in the engine module behind the hydraulic oil reservoir (Fig. 2-89:).

When the temperatures of the engine oil, engine coolant and the hydraulic oil are below -10°C / 14°F:

 Connect the system to the external power supply.

 Switch on the preheating system with switch (1, Fig. 2-89:).

The pilot lamp (2, Fig. 2-89:) lights up.

 Switch off the preheating system with switch (1, , Fig. 2-89:) when the engine and the hydraulic system have reached a temperature above 0°C / 32°F.

The pilot lamp (4, Fig. 2-89:) goes out.

 Switch on the fuel preheating system (see "Fuel preheating system (option)").
