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 onany 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 oil drain plug (B, Figure 8). Drain the oil into an approved container.
3. After the oil has drained, install and tighten the oil drain plug.
Change The Oil Filter (if equipped)
Some models are equipped with oil filter. For replacement intervals, see the
Maintenance chart.
1. Drain t he oil from the engine. See Remove Oil section.
2. Remove the oil filter (C) and dispose of properly. See Figure 9.
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
theoilfilter1/2to3/4turns.
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 10).
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 10).
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.
3. Install and tighten the dipstick.
4. Remove the dipstick andcheck 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 (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 f ilter and solvents will dissolve the filter.
See the Maintenance Chart for service requirements.
1. Open the latches (A) and remove the cover (B). See Figure 11.
2. Remove the nut (D) and the retainer (E).
3. Remove the air filter (F).
4. Remove the pre -cleaner (G), if equipped, from the air filter.
5. To loosen debris, gently tap the air filter on a hard surface. If the air filter is
excessively dirty, replace with a new air filter.
6. Wash the pre-cleaner in liquid detergent and water. Then allow it to thoroughly air
dry. Do not oil the pre-cleaner.
7. Assemble the dry pre-cleaner to the air filter.
8. Install the air filter and secure with retainer and nut.
9. Install and secure the cover.
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 the fuel filter.
3. Check t he 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). Make sure that the oil cooler fins
(D) are free of dirt and debris.
