MAINTENANCE
Servicing the Air Filter
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 sol-
vents will dissolve the filter.
1. Remove the cover (A, Figure 18).
2. Remove the filter (C) and the pre-cleaner (B).
3. To loosen debris, gently tap the filter on a hard sur-
face. 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 and the filter into the
engine base (D).
6. Install the cover.

Storage
WARNING
Never store the unit (with fuel) in an enclosed,
poorly ventilated structure. Fuel vapors can travel to
an ignition source (such as a furnace, water
heater, etc.) and cause an explosion. Fuel
vapor is also toxic to humans and animals.
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.
Equipment
Disengage the PTO, set the parking brake, and remove
the key.
Battery life will be increased if it is removed. Put in a cool,
dry place and fully charged about once a month. If the
battery is left in the unit, disconnect the negative cable.
Fuel System
Fuel can become stale when stored over 30 days. Stale
fuel causes acid and gum deposits to form in the fuel sys-
tem 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 car-
tridge.
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. See
Changing the Oil section .
Before starting the unit after it has been stored:
• Check all fluid levels. Check all maintenance items.
• Perform all recommended checks and procedures
found in this manual.
• Allow the engine to warm up for several minutes be-
fore use.
