Engine Oil
1. Change the engine oil
Engine Cylinder
2. Remove the spark plug
3. Pour a tablespoon (5 - 10 cc) of clean engine oil into the cylinder.
4. Pull the starter rope several times to distribute the oil in the cylinder.
5. Reinstall the spark plug.
6. Pull the starter rope slowly until resistance is felt and the notch on the starter pulley aligns with the hole
at the top of the recoil starter cover. This will close the valves so moisture cannot enter the engine cylinder.
Return the starter rope gently.
Storage Precautions
If your engine is being stored with petrol in the fuel tank and carburettor, it is important to reduce the hazard of
fuel vapour ignition. Select a well-ventilated storage area away from any appliance that operates with a flame,
such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark producing electric motor, or
where power tools are operated.
If possible, avoid storage areas with high humidity, because that promotes rust and corrosion.
Unless all fuel has been drained from the fuel tank, leave the fuel valve lever in the OFF position to reduce the
possibility of fuel leakage.
Position the equipment so the engine is level. Tilting can cause fuel or oil leakage.
With the engine and exhaust system cool, cover the engine to keep out dust. A hot engine and exhaust system
can ignite or melt some materials. Do not use sheet plastic as a dust cover. A nonporous cover will trap moisture
around the engine, promoting rust and corrosion.
If equipped with a battery for electric starter types, recharge the battery once a month while the engine is in
storage. This will help to extend the service life of the battery.
Removal from Storage
Check your engine as described in the BEFORE OPERATION/ON chapter of this manual.
If the fuel was drained during storage preparation, fill the tank with fresh petrol.
If you keep a container of petrol for refuelling, be sure that it contains only fresh petrol. Petrol oxidises and
deteriorates over time, causing hard starting with engine.
If the cylinder was coated with oil during storage preparation, the engine may smoke briefly at start-up. This is
normal.
Transporting
If the engine has been running, allow it to cool for at least 15 minutes before loading the engine-powered
equipment on the transport vehicle. A hot engine and exhaust system can burn you and can ignite some materials.
Keep the engine level when transporting to reduce the possibility of fuel leakage.
Turn the fuel valve lever to the OFF position.
