How To Service The Air Filter - Figure 9
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.
Cyclonic Air Filter System
1. Loosen the fasteners (A) and remove the cover (B). See Figure 9.
2. Open the latch (C) and remove the air filter (D). See Figure 10.
3. To loosen debris, gently tap the air filter on a hard surface. If the air filter is
excessively dirty, replace with a new air filter.
4. Install the air filter and close the latch.
5. Install the cover and secure the fasteners.
How To Clean The Air Cooling System - Figure 11
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 finger guard/rotating screen (A).
2. Keep linkage, springs and controls (B) clean.
3. Keep the area around and behind the muffler free of any combustible debris (Figure
11).
4. Make sure the oil cooler fins (C) are free of dirt and debris.
5. Loosen the fasteners (D) and remove the cover (E).
6. Loosen the fasteners (F) and open the debris access panels (G). Remove any grass
and debris that has accumulated on the cylinders.
7. Close the debris access panels and secure with the fasteners.
8. Install the cover and secure with the fasteners.
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 furnaces, 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 Advanced Formula Fuel Treatment & Stabilizer, available
wherever Briggs & Stratton genuine service parts are sold.
For engines equipped with a FRESH START
®
START available in 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 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 How To Change The Oil
section.
