WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
Running engines produce heat. Engine parts, especially muffler, become
extremely hot.
Severe thermal burns can occur on contact.
• 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.
• Allow muffler, engine cylinder and fins to cool before touching.
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.
For
Just Check & Add™
models, an oil change is not required. If you desire to change
oil, then follow the procedure below.
Remove Oil
You can 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 (D, Figure 16) and
keep it away from the spark plug (E).
2.
Remove the oil drain plug (F, Figure 17). Drain the oil into an approved container.
Note:
Any of the oil drain plugs (F, Figure 17) may be installed in the engine.
3.
After the oil has drained, install and tighten the oil drain plug (F, Figure 17).
4.
If you drain the oil from the top oil fill tube (C, Figure 18), keep the spark plug (E)
end of the engine up. Drain the oil into an approved container.
WARNING
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. To empty the fuel tank, run the engine until it
stops from lack of fuel.
Change Oil Filter, if equipped
Some models are equipped with an oil filter. For replacement intervals, see the
Maintenance Schedule.
1.
Drain the oil from the engine. See
Remove Oil
section.
2.
Remove the oil filter (G, Figure 19) and dispose of properly.
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. Correct oil level is at the top of the full
indicator (B, Figure 20) on the dipstick.
Add Oil
• Make sure the engine is level.
• Clean the oil fill area of any debris.
• See the
Specifications
section for oil capacity.
1.
Remove the dipstick (A, Figure 20) and wipe with a clean cloth.
2.
Slowly pour oil slowly into the engine oil fill (C, Figure 20).
Do not overfill.
After
adding oil, wait one minute and then check the oil level.
3.
Install and tighten the dipstick (A, Figure 20).
4.
Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 20) on the dipstick.
5.
Reinstall and tighten the dipstick (A, Figure 20).
6.
Connect the spark plug wire (D, Figure 16) to the spark plug (E).
Service Air Filter
See Figure: 21, 22
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Never start and 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.
See the
Maintenance Schedule
for service requirements.
Various models use either a foam or a paper filter. Some models may also have an
optional pre-cleaner that can be washed and reused. Compare the illustrations in this
manual with the type installed on your engine and service as follows.
Foam Air Filter
1.
Open the fastener(s) (A, Figure 21).
2.
Remove the cover (B, Figure 21).
3.
To prevent debris from falling into the carburetor, carefully remove the foam
element (C, Figure 21) from the air filter base.
4.
Wash the foam element (C, Figure 21) in liquid detergent and water. Squeeze dry
the foam element in a clean cloth.
5.
Saturate the foam element (C, Figure 21) with clean engine oil. To remove the
excess engine oil, squeeze the foam element in a clean cloth.
6.
Install the foam element (C, Figure 21) onto the air filter base.
7.
Install the cover (B, Figure 21) and secure with fastener(s) (A).
Paper Air Filter
1.
Loosen the fastener(s) (A, Figure 22).
2.
Remove the cover (B, Figure 22).
3.
To prevent debris from falling into the carburetor, carefully remove the pre-cleaner
(D, Figure 22) and the filter (C) from the air filter base.
4.
Remove the pre-cleaner (D, Figure 22), if equipped, from the filter (C).
5.
To loosen debris, gently tap the filter (C, Figure 22) on a hard surface. If the filter is
excessively dirty, replace with a new filter.
6.
Wash the pre-cleaner (D, Figure 22), if equipped, in liquid detergent and water.
Allow the pre-cleaner to throughly air dry.
Do not
oil the pre-cleaner.
7.
Assemble the dry pre-cleaner (D, Figure 22), if equipped, to the filter (C).
8.
Install the filter (C, Figure 22) and the pre-cleaner (D), if equipped, onto the air
filter base. Make sure the filter fits securely on the air filter base.
9.
Install the cover (B, Figure 22) and secure with the fastener(s) (A). Make sure the
fastener(s) is tight.
Service Fuel System
See Figure: 23
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.
• If fuel spills, wait until it evaporates before starting engine.
• Replacement parts must be the same and installed in the same position as the
original parts.
Fuel Filter, if equipped
1.
Before cleaning or replacing the fuel filter (A, Figure 23), 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, Figure 23) on the clamps (C), then slide the clamps
away from the fuel filter (A). Twist and pull the fuel lines (D) off of the fuel filter.
3.
Check the fuel lines (D, Figure 23) for cracks or leaks. Replace if necessary.
