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.
• When 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.
For models labeled
Just Check & Add™
and
No Oil Changes
, an oil change is not
required. If you desire to change oil, then follow the procedure below.
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
The oil must be drained from the top oil fill tube.
1.
With engine off but still warm, disconnect the spark plug wire (D, Figure 15) and
keep it away from the spark plug (E).
2.
Models with integrated battery:
Disconnect the wire harness (F, Figure 16) from
the electric starter.
3.
Remove the dipstick (A, Figure 17).
4.
When 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
When 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
• 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 17) and wipe with a clean cloth.
2.
Slowly pour oil into the engine oil fill (C, Figure 17).
Do not overfill.
After adding
oil, wait one minute and then check the oil level.
3.
Install and tighten the dipstick (A, Figure 17).
4.
Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 17) on the dipstick.
5.
Reinstall and tighten the dipstick (A, Figure 17).
6.
Connect the spark plug wire (D, Figure 15) to the spark plug (E).
Service Air Filter
See Figure: 19
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.
Paper Air Filter
1.
Open the cover (B, Figure 19).
2.
Remove the filter (C, Figure 19).
3.
Remove the pre-cleaner (E, Figure 19), if equipped, from the filter. 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, if equipped, to the filter.
6.
Install the filter (C, Figure 19).
7.
Close the cover (B, Figure 19).
Service 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.
1.
Use a brush or dry cloth to remove debris from the air intake grille.
2.
Keep linkage, springs and controls clean.
3.
Keep the area around and behind the muffler, if equipped, free of any combustible
debris.
4.
Make sure the oil cooler fins, if equipped, are free of dirt and debris.
After a period of time, debris can accumulate in the cylinder cooling fins and cause the
engine to overheat. This debris cannot be removed without partial disassembly of the
engine. Have a Briggs & Stratton Authorized Service Dealer inspect and clean the air
cooling system as recommended in the
Maintenance Schedule.
Lithium-Ion Battery Pack Disposal
WARNING
Battery chemicals are toxic and corrosive.
Fire or explosion can cause severe burns or death.
Electrical Shock
• 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.
