Adjust the gap, if necessary, by carefully bending the side electrode.

■Use a proper spark plug

Model	Type	Electrode gap

EW120R	NGK CMR6A	0.03 in.
EW120R	NGK CMR6A	(0.7 to 0.8 mm)
		(0.7 to 0.8 mm)

EW220R	NGK BR-6HS	0.02 to 0.03 in.
EW320TR	(CHAMPION RL86C)	(0.6 to 0.7 mm)

Electrode gap

ENGINE OIL CHANGE

Initial oil change : After 20 hours of operation

Thereafter

: Every 100 hours of operation

(a)When changing oil, stop the engine and loosen the drain plug.

Drain the used oil while the engine is warm. Warm oil drains quickly and completely.

CAUTION

To prevent injury, pay attention to the hot oil.

Make sure the fuel cap is tightly secured to avoid spillage.

(b)Re-install the drain plug before refilling oil.

Oil capacity

EW120R	2.7 oz (0.08 L)
EW220R	20.3 oz (0.6	L)
EW320TR	33.8 oz (1.0	L)

■Always use the best grade and clean oil. Contaminated oil, poor quality oil and shortage of oil cause damage to engine or shorten the engine life.
