3. Turn the fuel valve to the ON position. This will allow fuel in the fuel
tank to drain through the carburetor bowl.
4. Reinstall the drain screw and gasket.
Engine Oil
Change the engine oil (page 8).
Engine Cylinder
1. Remove the spark plug (page 9).
2. Pour a tablespoon (5 ~ 10 cc) of clean engine oil into the cylinder.
3. Slowly pull the starter grip a few times to distribute the oil in the
cylinder.
4. Reinstall the spark plug.
5. Pull the starter grip slowly
until resistance is felt.
Continue pulling slowly
until the arrow notch on
the starter pulley aligns
with the hole on the recoil
starter. Return the starter
grip gently. This will close
the valves so moisture
cannot enter the engine
cylinder.
PLACING IN STORAGE
If your pump will be stored with gasoline in the fuel tank and
carburetor, it is important to reduce the hazard of gasoline vapor
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 in the OFF position to reduce the possibility of fuel leakage.
Place the pump on a level surface. Tilting can cause fuel or oil
leakage.
With the engine and exhaust system cool, cover the pump 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 pump, promoting rust and corrosion.
REMOVAL FROM STORAGE
Check your pump as described in BEFORE OPERATION (page 3).
If the fuel was drained during storage preparation, fill the tank with
fresh gasoline. If you keep a container of gasoline for refueling, be
sure that it contains only fresh gasoline. Gasoline oxidizes and
deteriorates over time, causing hard starting.
If the cylinder was coated with oil during storage preparation, the
engine may smoke briefly at startup. This is normal.
