(4) Deposits and water are discharged from the container prior to launching the starter or 10 minutes after engaging the fuel.

(5) Assuming that the initiator runs out of fuel or replaces the filter element, it is necessary to eradicate the air in the oil circuit.

Four, coolant

(1) It is necessary to apply antifreeze in any climatic conditions.

(2) Check the coolant level according to the rules and add oil in case of shortage. Lack of coolant can cause the starter to overheat.
