STORAGE
• It is very important to prepare storage in the right way in order to keep the engine in good
condition�
• The following instructions aim to avoid rust and corrosion and to make it easier to start the
engine when it is to be used again�
• If the engine is to be stored with petrol in the tank and the carburettor, it is important to reduce
the risk of petrol fumes being ignited� Store the engine in a well ventilated location and not in
proximity to equipment such as boilers, water heaters and drying cabinets� Avoid areas where
sparking electric motors or power tools are used�
• If possible, avoid storage areas where there is a high level of humidity, which may contribute to
rust and corrosion�
• If there is fuel left in the tank, the fuel tap must be set in the OFF position in order to reduce the
risk of fuel leaks� Place the equipment so that the engine is level� If it is tilted, fuel or oil can leak
out�
• Once the engine and exhaust system has cooled, the engine must be covered in order to protect
it from dust� If the engine or exhaust system is hot, certain materials may melt� Do not use a
plastic sheet as a dust protector� If the protector is non-permeable, moisture will collect around
the engine and cause rust and corrosion�
