Operation
Engine preheater (option)
This equipment is for cold-starting at temperatures below 29 °F (–5°C).
The following “engine preheater” versions are available for the machine:
– Engine coolant preheater (option)
– Hydraulic oil preheater (option)
– Coolant preheater (option) and hydraulic oil preheater (option)
The operation of the different versions is the same.
Heating elements in the engine block and/or in the hydraulic oil tank warm up the engine
coolant circuit and/or the hydraulic oil according to the gravity principle (warm fluid rises
and is replaced by cold fluid). The coolant or the oil can only be thoroughly warmed up to
service temperature if the engine preheater is connected over a longer period of time –
preferably over night.
Connecting the engine preheater (option)
☞
Connect the engine preheater as follows:
•
Park the machine near a 220 V socket
•
First connect special cable A to machine socket B on the service panel on the left
side of the machine, then
•
Insert the plug into the 220 V socket
☞
Before starting the engine:
•
Pull out the plug from the 220 V socket
•
Unplug special cable A from machine socket B
NOTE:
The engine preheater (option) reduces engine emissions during the warm-up
phase by up to 50%, saving fuel at the same time.
