Before performing adjustments or repairs:

• Disconnect the spark plug wire and keep it away from the spark plug.

• Disconnect battery at negative terminal (only engines with electric start.)

• Tie up long hair and remove jewelry.

When testing for spark:

• Use approved spark plug tester.

• Do not wear loose-fitting clothing, dangling drawstrings or items that could

become caught.

• Do not check for spark with spark plug removed.

WARNING

Running engines produce heat. Engine parts, especially muffler,

become extremely hot.

Severe thermal burns can occur on contact.

Combustible debris, such as leaves, grass, brush, etc. can catch fire.

• Allow muffler, engine cylinder and fins to cool before touching.

• Remove accumulated debris from muffler area and cylinder area.

• It is a violation of California Public Resource Code, Section 4442, to use or

operate the engine on any forest -covered, brush-covered, or grass-covered land

unless the exhaust system is equipped with a spark arrester, as defined in

Section 4442, maintained in effective working order. Other states or federal

jurisdictions may have similar laws. Contact the original equipment

manufacturer, retailer, or dealer to obtain a spark arrester designed for the

exhaust system installed on this engine.

* Below 40°F(4°C) the use of SAE 30 will result in hard starting.

** Above 80°F(27°C) the use of 10W-30 may cause increased oil consumption. Check

oil level more frequently.
