Emptying the chamber of the pump (XVIII)
Unscrew the drain valve cover. Let the water flow out of the chamber of the pump. Incline the pump so as to empty the chamber
of the pump thoroughly. Rinse the chamber of the pump with clean water in order to remove any contamination. The chamber of
the pump must be emptied after each use of the pump. It is prohibited to store the pump with a full chamber.
Storage of the pump
Proper maintenance before storage permits a longer and more reliable operation of the pump. Empty the fuel tank, for example using a plastic fuel pump, available in retail. Start the engine and leave it idling until it turns off. It will clean the carburettor from
fuel residues. Wait until the engine has cooled down. Empty the chamber of the pump of water. Rinse the chamber with clean
water, eliminating all contamination.
Remove the sparking plug. Pour a spoonful of oil through the socket to the two-stroke engine. Pull slightly the starting cable a few
times, which will permit to distribute the oil in the combustion chamber. Install the sparking plug. Clean the housing.
The pump must be stored in a cool, dry and well-ventilated place, far from sources of ignition.
Restarting the pump
Remove the sparking plug. Pull slightly the starting cable a few times, which will permit to clean the combustion chamber from oil
residues. Refill the fuel tank. Execute the engine start procedure.
