Tsurumi’s Operation, Service, and Repair Manual
4-3 Air Cleaner Service
WARNING
•
Never use gasoline or low flash point solvents for cleaning the air cleaner element. A fire
or explosion could result.
A dirty air cleaner will restrict airflow to the carburetor. To prevent degraded engine operation, service
the air cleaner regularly. Service more frequently when operating the engine in extremely dusty areas.
NOTE:
•
Never run the engine without the air cleaner. Rapid engine wear will result from contaminants,
such as dust and dirt, being drawn through the carburetor and into the engine.
4-4 Sediment Cup Cleaning
WARNING:
•
Gasoline is extremely flammable and is explosive under certain conditions. Do not smoke
or allow open flames or sparks in the area.
A.
Turn the fuel valve to OFF (refer to Figure 2-1).
B.
Remove the sediment cup and O-ring. Wash both parts in nonflammable or high flash point
solvent.
C.
Wipe the sediment cup and O-ring dry, then reinstall.
WARNING:
•
After installing the sediment cup, check for leaks, and make sure the area is free of resid-
ual fuel spills or seepage before starting the engine.
D.
Set the fuel shutoff valve (Figure 2-1) to ON. Check for leaks.
4-5 Cleaning and Adjusting Spark Plug
Recommended spark plugs: BPR6ES (NGK)
W20EPR-U (NIPPONDENSO)
A.
To ensure proper engine operation, the spark plug must be properly gapped and free of
deposits.
B.
Remove the spark plug cap.
C.
Clean any dirt from around the spark plug base.
D.
Use the proper size spark plug wrench to remove the spark plug.
WARNING
•
THE MUFFLER BECOMES VERY HOT DURING OPERATION AND REMAINS HOT FOR A
WHILE AFTER STOPPING THE ENGINE. BE CAREFUL NOT TO TOUCH THE MUFFLER
WHILE IT IS HOT.
E.
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.
