2. PERIODIC INSPECTION

Periodic maintenance is vital to the safe and efficient operation of your pump.

Check the table below for periodic maintenance intervals.

IT IS ALSO NECESSARY FOR THE USER OF THIS PUMP TO CONDUCT THE MAINTENANCE AND ADJUSTMENTS ON THE EMISSION-RELATED PARTS LISTED BELOW TO KEEP THE EMISSION CONTROL SYSTEM EFFECTIVE.

The emission control system consists of the following parts :

(1)Carburetor and internal parts

(2)Cold start enrichment system, if applicable

(3)Intake manifold, if applicable

(4)Air cleaner elements

(5)Spark plug

(6)Magneto or electronic ignition system

(7)Spark advance/ retard system, if applicable

(8)Exhaust manifold, if applicable.

(9)Hoses, belts, connectors, and assembles

The maintenance schedule indicated in the following table is based on the normal engine operation.

Should the engine be operated in extremely dusty condition or in heavier loading condition, the maintenance intervals must be shortened depending on the contamination of oil, clogging of filter elements, wear of parts, and so on.

Periodic Maintenance Schedule table

CAUTION

Replace rubber pipes for fuel passage every two years. If fuel leakage is found, replace the pipe immediately.

3.INSPECTING THE SPARK PLUG (See Fig.7-q)

(1)Clean off carbon deposits on the spark plug electrode using a plug cleaner or wire brush.

(2)Check electrode gap. The gap should be 0.6 mm to 0.7 mm (0.02 inch. - 0.03 inch.). Adjust the gap, if necessary, by carefully bending the side electrode.
