∙ 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.
Remove accumulated debris from muffler area and cylinder area. Inspect the muffler (A, Figure 8) for cracks, corrosion, or other damage. Remove the spark arrester (B), if equipped, and inspect for damage or carbon blockage. If damage is found, install replacement parts before operating.

WARNING

Fuel and its vapors are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

∙If you drain the oil from the top oil fill tube, the fuel tank must be empty or fuel can leak out and result in a fire or explosion.

Used oil is a hazardous waste product and must be disposed of properly. Do not discard with household waste. Check with your local authorities, service center, or dealer for safe disposal/recycling facilities.

Remove Oil

Drain the oil from the bottom drain hole or from the top oil fill tube.

1.With engine off but still warm, disconnect the spark plug wire (A) and keep it away from the spark plug (Figure 9).

2.Remove the oil drain plug (B, Figure 10). Drain the oil into an approved container. Note: Any of the oil drain plugs shown below may be installed in the engine.

3.After the oil has drained, install and tighten the oil drain plug.

4.If you drain the oil from the top oil fill tube (C), keep the spark plug end of the engine (D) up (Figure 11). Drain the oil into an approved container.

How To Service The Air Filter - Figure 12 13

WARNING

Fuel and its vapors are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

WARNING: Replacement parts must be of the same design and installed

in the same position as the original parts. Other parts may not perform as well, may damage the unit, and may result in injury.

∙Never start or run the engine with the air cleaner assembly (if equipped) or the air filter (if equipped) removed.

NOTICE: Do not use pressurized air or solvents to clean the filter. Pressurized air can damage the filter and solvents will dissolve the filter.

Two types of air filter systems are shown, a Standard and a High Capacity. Determine the type installed on your engine and service as follows.

Standard Air Filter - Figure 12

The air cleaner system uses a foam element that can be washed and reused.

1. Move the slide lock (A) to the unlock position. Open the cover (B). See Figure 12.
