Inspect Muffler And Spark Arrester - Figure 6
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.
Remove accumulated debris from muffler area and cylinder area. Inspect the muffler (A,
Figure 6) 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:
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.
How To Change The Oil - Figure 7
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
1. With engine off but still warm, disconnect the spark plug wire (A) and keep it away
from the spark plug (Figure 7).
2. Remove the dipstick (D).
Standard Oil Drain Plug
1. Remove the oil drain plug (B, Figure 8). Drain the oil into an approved container.
Note: Any of the oil drain plugs shown below may be installed in the engine.
2. After the oil has drained, install and tighten the oil drain plug.
Optional Quick Oil Drain
1. Disconnect the oil drain hose (G, Figure 9) from the side of the engine.
2. Turn and remove the oil drain cap (H). Carefully lower the quick oil drain (I) into an
approved container (J).
3. After the oil has drained, install the oil drain cap. Attach the oil drain hose to the side
of the engine.
Change The Oil Filter (if equipped)
Some models are equipped with oil filter. For replacement intervals, see the
Maintenance chart.
1. Drain the oil from the engine. See Remove Oil section.
2. Remove the oil filter (C) and dispose of properly. See Figure 10.
3. Before you install the new oil filter, lightly lubricate the oil filter gasket with fresh,
clean oil.
4. Install the oil filter by hand until the gasket contacts the oil filter adapter, then tighten
the oil filter 1/2 to 3/4 turns.
5. Add oil. See Add Oil section.
6. Start and run the engine. As the engine warms up, check for oil leaks.
7. Stop the engine and check the oil level. It should be at the top of the full indicator (F)
on the dipstick (Figure 7).
Add Oil

How To Service The Air Filter - Figure 13
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
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.
The air filter system uses either a flat or a cylindrical cartridge air filter. Some models are
also equipped with a pre-cleaner that can be washed and reused.
Flat Air Filter (Figure 13)
1. Pull up on the cover handle (A, Figure 13). Rotate the cover handle toward the
engine and then remove the cover (B).
2. Remove the pre-cleaner (C), if equipped, and the filter (D).
3. To loosen debris, gently tap the filter on a hard surface. If the filter is excessively
dirty, replace with a new filter.
4. Wash the pre-cleaner in liquid detergent and water. Then allow it to thoroughly air
dry. Do not oil the pre-cleaner.
5. Assemble the dry pre-cleaner and the filter into the engine base (E).
6. Align the tabs (F) on the cover with the slots (G) in the blower housing. Rotate the
cover handle back and push down to lock in place.
Cylindrical Cartridge Air Filter (Figure 14)
1. Remove the fasteners (A) and the air filter cover (B). See Figure 14.
2. To remove the filter (C), lift the end of the filter and then pull the filter off the intake
(D).
3. Remove the pre-cleaner (E), if equipped, from the filter.
4. To loosen debris, gently tap the filter on a hard surface. If the filter is excessively
dirty, replace with a new filter.
5. Wash the pre-cleaner in liquid detergent and water. Then allow it to thoroughly air
dry. Do not oil the pre-cleaner.
6. Assemble the dry pre-cleaner to the filter.
7. Install the filter on the intake. Push the end of the filter into the base as shown. Make
sure filter fits securely in the base.
8. Install air filter cover and secure with fasteners.
How To Replace The Fuel Filter - Figure 11
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition
•
sources.
Check fuel lines, tank, cap, and fittings frequently for cracks or leaks.
•
Replace if necessary.
Before cleaning or replacing the fuel filter, drain the fuel tank or close the fuel
•
shut-off valve.
Replacement parts must be the same and installed in the same position as the
•
original parts.
If fuel spills, wait until it evaporates before starting engine.
•
1. Before replacing the fuel filter (A, Figure 11), if equipped, drain the fuel tank or close
the fuel shut-off valve. Otherwise, fuel can leak out and cause a fire or explosion.
2. Use pliers to squeeze tabs (B) on the clamps (C), then slide the clamps away from
the fuel filter. Twist and pull the fuel lines (D) off of the fuel filter.
3. Check the fuel lines for cracks or leaks. Replace if necessary.
4. Replace the fuel filter with an original equipment replacement filter.
5. Secure the fuel lines with the clamps as shown.
