Air Cleaner maintenance instrucons
A dirty air cleaner will restrict air ow to the carbureor. To prevent carbureor malfuncon, service the air cleaner regularly. Service more frequently when
operang the pump in extremely dusty areas.
Warning: Never use gasoline or low ash point solvents for cleaning the air cleaner element. A re or explosion could result.
Never run the engine without the air cleaner. Rapid engine wear will result from contaminants, such as dust and dirt being drawn into the engine.
1. Unscrew the wing nut, remove the air cleaner cover and remove the foam element.
2. Wash the element in soluon of household detergent and warm water, then rinse thoroughly, or wash in non-ammable or high ash point solvent. Allow
the element to dry thoroughly.
3. Soak the element in dean engine oil and squeeze out the excess oil. The engine will smoke during inial start-up if too much oil is le in the element.
4. Reinstall the air cleaner element and the cover.
Spark plug maintenance instrucons
In order to service the spark plug, you will need a spark plug wrench (commercially available).
Recommended spark plug: F7TC/F7RTC
To ensure proper engine operaon, the spark plug must be properly gapped and free of deposits.
Warning: If the engine has been running, the muer will be very hot. Be careful not to touch the muer.
1. Remove the spark plug cap.
2. Clean any dirt from around the spark plug base.
3. Use a spark plug wrench to remove the spark plug.
4. Visually inspect the spark plug. Discard it if the insulator is cracked or chipped. Clean the spark plug with a wire brush if it is to be reused.
5. Measure the plug gap with a feeler gauge. Correct as necessary by carefully bending the side electrode. The gap should be: (0.70-0.80mm)
6. Check that the spark plug washer is in good condion, and thread the spark plug in by hand to prevent cross- threading.
Aer the spark plug is seated, ghten with a spark plug wrench to compress the washer.
If installing a new spark plug, ghten 1/2 turn aer the spark plug seats to compress the washer. If reinstalling a used spark plug, ghten 1/8-1/4 turn aer
the spark plug seats to compress the washer.
Noce: The spark plug must be securely ghtened.
An improperly ghtened spark plug can become very hot and could damage the engine.
Never use spark plugs which have an improper heat range. Use only the recommended spark plugs or equivalent.
Transportaon / storage
Warning: To avoid a re, make sure to cool the water pump down thoroughly before transportaon or storage in room.
Transport the water pump with the fuel cock turned o, besides, keep it horizontal to prevent fuel from spilling. Spilled gasoline and gasoline vapour may ignite.

2. Clean the water pump inside.
If the water pump is used to pump water mud, sand or heavy debris, deposit of such may remain inside it. Before storage, operate the water pump to suck
into fresh water to wash, otherwise impeller may be damaged once reuse. Finishing wash, drive o the water drain plug, then empty the water in the pump
thoroughly, and reinstall the water drain plug.
3. Empty fuel inside the fuel tank.
a. Set the fuel cock to OFF, drive o the fuel drain plug of the carbureor oater room, drain out the fuel in the carbureor. Hold drained gasoline in a proper
container.
b. Set the fuel cock to ON.
