4.12 PREHEATING KIT (OPTIONAL)
The machine is equipped with a preheating kit to be used when room temperatures are included
between -10°C and -20°C.
This kit is composed by a gas-oil burner and by an heating circuit that uses the cooling liquid of the
diesel engine: the consumption heated by the preheating kit are the diesel engine block, the hydraulic
oil tank, the diesel engine gas-oil tank and the delivery of the gas-oil to the diesel engine.
The gas-oil for the preheating kit burner has to have the following technical specifications (DIN 51601):

70% winter gas-oil

30% petroleum or kerosene
In case of temperatures higher than -10°C, or whatever when the preheating system is not used, set
the two cocks for the preheating circuit cut out (table 8, pos. 3-5) on SUMMER position, while when
the preheating system is used, set the cocks on WINTER position.
ATTENTION: before starting the preheating system, check if the two cocks are on
WINTER position. On the contrary, the preheating system doesn't work and may be
damaged.
To start the preheating system, push the push-button on the control panel: the system starts
automatically.
ATTENTION: when the diesel engine is working, the preheating kit has to be switched
off.
ATTENTION: for using the heater, the pump blow-by selector has to be on automatic
position (leftwards).
Once stopped the preheating system and with functioning diesel engine, if the operator wishes to heat
the gas-oil and hydraulic oil tanks, it is possible to activate the liquid blow-by pump acting on the
selector
– manual position (rightwards).
Please consider that the heater liquid reaches the service temperatures in about 20 functioning
minutes, while after 30 functioning minutes of the heater, the temperature of the hydraulic oil in the
relevant tank increases of about 10°.
