• 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.
• 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.
Storage
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
Electrical Shock
When Storing Fuel Or Equipment With Fuel In Tank
• Store away from furnaces, stoves, water heaters or other appliances that have pilot
lights or other ignition sources because they can ignite fuel vapors.
When Storing Battery Pack and Battery Charger
• Keep battery charger dry. Avoid exposing battery pack to rain or wet conditions.
Fuel System
See Figure: 22, 23
Note:
Some models have a fuel tank for vertical storage that will let the engine tilt for
maintenance or storage (C, Figure 22). Do not store in vertical position with fuel tank filled
above the bottom of the fuel level indicator (D). For further instructions, see the equipment
manual.
Store the engine level (normal operating position). Fill fuel tank (A, Figure 23) with fuel.
To allow for expansion of fuel, do not overfill above the fuel tank neck (B).
Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum deposits
to form in the fuel system or on essential carburetor parts. To keep fuel fresh, use Briggs
& Stratton Advanced Formula Fuel Treatment & Stabilizer, available wherever Briggs
& Stratton genuine service parts are sold.
There is no need to drain gasoline from the engine if a fuel stabilizer is added according
to instructions. Run the engine for two (2) minutes to circulate the stabilizer throughout the
fuel system before storage.
If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into
an approved container. Run the engine until it stops from lack of fuel. The use of a fuel
stabilizer in the storage container is recommended to maintain freshness.
Engine Oil
While the engine is still warm, change the engine oil. See the
Change Engine Oil
section.
Battery Pack and Charger
See Figure: 24
When not in use, disconnect charger and store in a cool, dry area. Wet, damp areas can
cause corrosion of terminals and electrical contacts. If stored for long periods in high
temperatures (120° F / 49° C), permanent damage to the battery pack can result. Check
electrical terminals and contacts on battery packs and charger. Wipe with clean cloth or
blow clean with compressed air.
After storage, a normal charge may be required. To check available charge, press the
Battery Fuel Gauge button (E, Figure 24) and charge if required. See the
Battery Fuel
Gauge
section.
