Air Cleaner Maintenance
A dirty air cleaner will decrease the airflow quantity through the carburetor. To avoid issues with the
carburetor, clean the air cleaner regularly. In extremely dusty areas, this should be done more often.
⚠
WARNING
Never clean the air cleaner in gasoline or low-flash point solvent, for gasoline and low-flash point
solvent may produce flames and even an explosion in certain conditions.
CAUTION
Never operate the water pump without the air cleaner installed. In the case that dirt and dust is
sucked into the engine, the engine will wear out more quickly.
1.
Drive off the thumbnut and remove the air cleaner cover and filter element.
2.
Replace the filter element with a factory approved filter.
3.
Reinstall the removed parts.
Spark Plug Maintenance
To keep the engine in good, working condition, check the spark plugs regularly and keep them clean
and free of accumulated carbon.
1. Remove the spark plug cap.
⚠
WARNING
When the engine has been running, the exhaust muffler is very hot and dangerously hot to the touch.
2. Check the spark plug visually. If there are signs of wear around it or the gasket is cracked, replace
it with a new one. Before reinstalling a spark plug, clean it with a wire brush.
3. Measure the spark plug gap with a feeler gauge and adjust it by bending the side electrode. The
spark plug clearance should be 0.70-0.80mm.
4. Check that the spark plug gasket is in good condition or replace it with a new one. Drive it into the
engine with a spark plug wrench to protect the thread from being damaged.
Note : When installing a new spark plug, after it touches and presses the gasket, twist a half turn; for a
used spark plug, twist 1/8-1/4 turn.
