Storage
1. Thoroughly clean the unit by removing all grass clippings
and debris.
2. Perform maintenance and lubrication as required.
3. Drain the fuel from the fuel tank (unless using a fuel
stabilizer - Refer to “Fuel System”).
4. Start the engine and allow it to run until the engine runs
out of fuel. This allows the carburetor and fuel system to
remain clean during storage.
5. Remove and store the battery. Refer to “How To Store
The Battery”.
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
®
fuel cap, use
Briggs & Stratton FRESH START
®
available in a drip con-
centrate 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 sta-
bilizer, 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 main-
tain freshness.
