1.5.3 ENGINE OIL REQUIREMENTS
Use only high quality detergent oil rated with American
Petroleum Institute (API) Service Classification SF,
SG or SH. The recommended oil weights include the
following:
• During summer months: SAE 30. An acceptable
substitute is SAE 10W-30.
• During winter months: SAE 5W-30. DO NOT USE
SAE 10-W40.
Crankcase and oil filter capacity is approximately
800 mL or .84 U.S. quarts. Do NOT use special addi-
tives. See Sections 3.1 and 3.2 (Page 12) for oil level
check and fill procedures.

1.5.6 EMISSIONS COMPLIANCE PERIOD
For non-handheld engines the Emissions Compliance
Period referred to on the Emissions Compliance
Label indicates the number of operating hours for
which the engine has been shown to meet Federal
emission requirements.
• For engines less than 225 cc displacement, Category
C=125 hours, B=250 hours, and A=500 hours.
• For engines of 225 cc or more, Category C=250
hours, B=500 hours, and A=1000 hours.

2.1.1 START/STOP SWITCH
To crank and start the engine, hold this switch in the
START position. Release the switch when the engine
starts. To stop an operating engine, press and hold
the switch in the STOP position until the engine shuts
off. The switch center position is the RUN position.
2.1.2 FUSE
The fuse protects the engine’s DC control circuit
against electrical overload. If the fuse element has
melted open due to overloading, the engine cannot
be cranked. If the fuse must be replaced, use only an
identical replacement.
2.1.3 MAIN BREAKER
The main breaker protects the generator’s AC out-
put circuit against overload and provides a method
of turning OFF the generator’s 120-volt AC output
to the vehicle circuits. The generator has a 30-amp
breaker.
