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 (E), keep the spark plug end of the engine
(F) up (Figure 11). 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.
See the Specifications section for oil capacity.
1. Remove the dipstick (G) and wipe with a clean cloth (Figure 2, Figure 3).
2. Pour the oil slowly into the engine oil fill (H). 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
(J) on the dipstick.
5. Install and tighten the dipstick.
How To Service The Air Filter - Figure
12 13
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.
Two types of air f ilter systems are shown, a Standard and a High Capacity. Determine
the type installed on your engine and service as follows.
Standard Air Filter - Figure
12
The standard air filter uses a foam element that can be washed and reused.
1. Remove the screw (A) from the top of the air filter assembly (B). See Figure 12.
2. To prevent debris from falling into the carburetor, carefully remove the air filter
assembly.
3. Remove the foam element (C) from the air filter base.
4. Wash the foam element in liquid detergent and water. Squeeze dry the foam element
in a clean cloth.
5. Saturate the foam element with clean engine oil. To remove the excess engine oil,
squeeze the foam element in a clean cloth.
6. Install the foam element into the air filter base.
7. Install the air filter assembly onto the carburetor and secure with screw.
High Capacity Air Filter - Figure
13
The high capacity air filter uses a pleated filter.
1. Remove the screw (A) from the top of the air filter assembly (B). See Figure 13.
2. To prevent debris from falling into the carburetor, carefully remove the air filter
assembly.
3. Remove the pleated filter (C) from the air f ilter base.
4. To loosen debris, gently tap the pleated filter on a hard surface. If the pleated filter is
excessively dirty, replace with a new filter.
5. Install the pleated filter.
6. Install the air filter assembly onto the carburetor and secure with screw.
Clean Air Cooling System - Figure
14
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 (A). Keep linkage,
springs and controls (B) clean. Keep the area around and behind the muffler (C)freeof
any combustible debris (Figure 14).
Storage
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Storing Fuel Or Equipment With Fuel In Tank
Store away from f urnaces, stoves, water heaters or other appliances that have
pilot lights or other ignition sources because they can ignite fuel vapors.
Fuel System
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 FRESH START
®
fuel stabilizer, available as a liquid additive or a
drip concentrate cartridge.
There is no need to drain gasoline from the engine if a fuel stabilizer is added according
to instructions. Run the engine for 2 minutes to circulate the stabilizer throughout the fuel
system. The engine and fuel can then be stored up to 24 months.
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.
NOTICE: Store the engine level (normal operating position). If the engine is tipped for
storage, the fuel tank must be empty and the spark plug side must be up. If the fuel
tank is not empty and if the engine is tipped in any other direction, it may be difficult to
start due to oil or gasoline contaminating the air filter and/or the spark plug.
