	fuel filter		→ fuel filter is clogged	→ clean
	carburetor adjustment screw		→ out of normal range	→ adjust to normal range
	sparking (no spark)		→ spark plug is fouled/wet	→ clean/dry
			→ plug gap is incorrect	→ correct (GAP: 0.6 to 0.7 mm)
	spark plug	→ disconnected	→ retighten
Case 2. Engine starts but does not keep running/hard re-starting
	CHECK		PROBABLE CAUSES	ACTION
	fuel tank		→ incorrect fuel or staled fuel	→ drain it and use correct fuel

	muffler, cylinder (exhaust port)		→ carbon is built-up	→ wipe away
	air cleaner		→ clogged with dust	→ wash
	cylinder fin, fan cover		→ clogged with dust	→ clean
Case 3. No suction of water
	CHECK		PROBABLE CAUSES	ACTION
	self-suction port		→ insufficient self-sucking water in pump	→ top up with water(see Page 7)

Case 4. Discharge water flow rate too small
	CHECK		PROBABLE CAUSES	ACTION
	strainer		→ clogged suction strainer	→ cleaning of suction strainer
	pump position		→ pump position too high from water level → lowering pump height to water level
	water resource		→ too far or too high place to discharge	→ secure water resource near to discharge place
	fuel		→ engine output too low	→ check fuel degrading, water ingress.
				Replace if needed (see Page 7)
	air filter		check air filter clogging, cleaning
				(see Page 9)
	fuel filter		check fuel filter clogging, cleaning
				(see Page 9)
	carburetor		carburetor adjustment
	suction side		→ air invasion at suction side	→ check piping at suction side
	hose		→ thin or long or kink of hose	→ thicken or shorten or straighten
	water resource		→ leak of water from water resource	→ stop leak
