Inspect Muffler And Spark Arrester - Figure
7
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.
• It is a violation of California Public Resource Code, Section 4442, to use or
operate the engine onany forest-covered, brush-covered, or grass-covered land
unless the exhaust system is equipped with a spark arrester, as defined in
Section 4442, maintained in effective working order. Other states or federal
jurisdictions may have similar laws. Contact the original equipment
manufacturer, retailer, or dealer to obtain a spark arrester designed for the
exhaust system installed on this engine.
Inspect the muffler (A, Figure 7) for cracks, corrosion, or other damage. Remove the
spark arrester ( B), if equipped, and inspect for damage or carbon blockage. If
replacement parts are required, make sure to use only original equipment replacement
parts.
WARNING: Replacement parts must be the same and installed in the
same position as the original parts or fire could result.

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
1. With engine off but still warm, disconnect the spark plug wire (A) and keep it away
from the spark plug (Figure 9).
2. Remove the oil drain plug (B, Figure 10). Drain the oil into an approved receptacle.
Note: Any of the oil drain plugs shown below may be installed in the engine.
3. After the oil has drained, install and tighten the oil drain plug.
Add oil
• Place engine level.
• Clean the oil fill area of any debris.
• See the Specifications section for oil capacity.
Models with short dipstick
1. Remove the dipstick (F, Figure10) and wipe with a clean cloth.
2. Pour the oil slowly into the engine oil fill (E). Fill to point of overflowing.
3. Install the dipstick but do not screw in. Remove and check the oil level. Oil level
should be at the FULL mark (G) on the dipstick.
4. Install and tighten the dipstick.
Models with extended dipstick
1. Remove the dipstick (F, Figure 11) and wipe with a clean cloth.
2. Pour the oil slowly into the engine oil fill (E). Do not overfill. After adding oil, wait
one minute and then recheck the oil level.
3. Install and tighten the dipstick.
4. Remove the dipstick andcheck the oil level. It should be at the top of the full indicator
(G) on the dipstick.
5. Install and tighten the dipstick.
How To Service The Air Filter - Figure
13 14
WARNING
Gasoline 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 or the air filter
removed.
NOTICE: Do not use pressurized air or solvents to clean the filter. Pressurized air can
damage the f ilter 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 fasteners (D) that hold the cover (A).
2. Open the cover and remove the pre-cleaner (C), the filter retainer (H), if equipped,
and the f ilter (B). See Figure 13 and 14..
3. 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. Install the dry pre-cleaner, the filter retainer (if equipped), and the filter.
6. On models equipped with air filter shown in Figure 13, install the cover tabs (E)into
the slots (F).
7. Install cover and secure with the fasteners. Make sure the fasteners are tight.
How To Clean The Fuel Filter - Figure
12
WARNING
Gasoline and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Keep gasoline 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. Close the fuel shut-off valve (B, Figure 12) and let the engine run until it stops.
Otherwise, fuel can leak out and cause a fire.
2. Remove the bowl (C) with a wrench. Clean debris from the filter (A) and the bowl.
3. Check the filter and bowl for cracks or other damage. Replace if necessary.
4. Install the filter, the gasket (D), and bowl. Tighten with a wrench.
5. Open the fuel shut-off valve and check for leaks.
How To Clean The Air Cooling System - Figure
8
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) (Figure 8). Keep
linkage, springs and controls (B) clean. Keep the area around and behindthe muffler (C)
free of any combustible debris.
Storage
WARNING
Gasoline and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Storing Gasoline Or Equipment With Fuel In Tank
• Store away f rom furnaces, stoves, water heaters or other appliances that have
pilot lights or other ignition sources because they can ignite gasoline 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 for2 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 notbeen 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.
