How To Change The Oil ‐
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
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 (A, Figure 11) and keep
it away from the spark plug.
2. The engine is equipped with a bottom drain (B, Figure 12). Remove the oil drain plug
(C). Drain the oil into an approved container.
Note:
Any of the oil drain plugs (C) shown 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 (D, Figure 13), keep the spark plug end of
the engine (E, Figure 13) 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.
Add Oil
Place engine level.

Clean the oil fill area of any debris.

Specifications
See the section for oil capacity.

1. Remove the dipstick (F, Figure 2) and wipe with a clean cloth.
2. Pour the oil slowly into the engine oil fill (G). 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 and check the oil level. It should be at the top of the full indicator
(H) on the dipstick.
5. Install and tighten the dipstick.
How To Service The Air Filter ‐
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 cleaner system uses a pleated filter with an optional pre‐cleaner. The pre‐cleaner
can be washed and reused.
1. Loosen the fastener (A, Figure 15) that holds the cover (B).
2. Open the cover and remove the pre‐cleaner (C) 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. Remove the pre‐cleaner from the 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.

How To Replace The Fuel Filter ‐
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 14), 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 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 ‐
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.

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 air intake grille (A, Figure 16). Keep
linkage, springs and controls (B) clean. Keep the area around and behind the muffler (C)
free of any combustible debris.
Lithium‐Ion Battery Pack Disposal
WARNING
Battery chemicals are toxic and corrosive.
Fire or explosion can cause severe burns or death.
Never burn or incinerate discarded or used battery packs as they may explode.

Toxic fumes and materials are created when battery packs are burned.
Do not use a battery that has been crushed, dropped, or damaged.

Used and discarded battery packs will likely still carry a small electrical charge and
should be handled with care. Always dispose of discarded or used battery packs
according to federal, state and local regulations.
