Inspect Muffler And Spark Arrester - Figure 6
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.
WARNING
• 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.
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
replacement parts are required, make sure to use only original equipment replacement
parts.
WARNING: Replacement parts must be the same and installed in the
same position as the original parts or fire could result.
How To Change The Oil - Figure 7 8 9 10
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
• Place engine level.
• Clean the oil fill area of any debris.
• See the Specifications section for oil capacity.
1. Remove the dipstick (D) and wipe with a clean cloth (Figure 7).
2. Pour the oil slowly into the engine oil fill (E). Do not overfill. After adding oil, wait
one minute and then check the oil level.
Note: Do not add oil at the quick oil drain (I) (if equipped).
3. Install and tighten the dipstick.
4. Remove the dipstick and check the oil level. It should be at the top of the full indicator
(F) on the dipstick.
5. Install and tighten the dipstick.
How To Service The Air Filter - Figure 11
WARNING
Gasoline 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 or the air filter
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 oval cartridge. Some models are also equipped
with a pre-cleaner that can be washed and reused.
Flat Air Filter
1. Pull up on the cover handle (A, Figure 11). 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.
How To Replace The Fuel Filter - Figure 12
WARNING
Gasoline and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Keep gasoline 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 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 12), 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.
How To Clean The Air Cooling System - Figure 13
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.
WARNING
• Allow muffler, engine cylinder and fins to cool before touching.
• Remove accumulated debris from muffler area and cylinder area.
NOTICE: Do not use water to clean the engine. Water could contaminate the fuel
system. Use a brush or dry cloth to clean the engine.
This is an air cooled engine. Dirt or debris can restrict air flow and cause the engine to
overheat, resulting in poor performance and reduced engine life.
Use a brush or dry cloth to remove debris from the finger guard/rotating screen (A).
Keep linkage, springs and controls (B) clean. Keep the area around and behind the
muffler (C) free of any combustible debris (Figure 13).
