Special recommendations
Occasional use of unit will keep the unit functional.
Removal of water from the tank
During the period of use, add isopropyl alcohol-based (not ethyl or methyl based)
anti-freeze for petrol vehicles (carburettor spirit) to the fuel. The agent should be
added after the tank has been emptied, and refi lled, a few times, and always at the
beginning and end of an operating season. The anti-freezing agent binds the water
in the fuel and prevents the fuel from settling and spoiling during the summer sea-
son. For the dosage, observe the recommendations provided by the manufacturer
of the agent.
Winter storage

•
the fuel tank is cleaned and the fuel tube fi lter is changed.
•

•
The unit doesn’t need any actions.
