Prepare the mower for “end of season” storage as fol-
lows:
1. Disconnect the spark plug wire and secure away
from the spark plug.
2. Drain the fuel tank and let the engine run until all
fuel is out of the carburetor.
NOTE: If using a fuel stabilizer, there is no need to
drain the fuel tank. Refer to the section entitled ‘Fuel
System’.
3. Use a brush or compressed air to remove loose
debris, then use a damp cloth to wipe down the
unit.
4. Tilt the mower up on its rear wheels and inspect
the underside of the deck. (Do not tilt the mower
with the spark plug or carburetor down.) Scrape
away stubborn accumulation of grass with a putty
knife and/or wire brush.
5. Lubricate all exposed metal with a light coating of
oil to prevent corrosion.
6. Carefully fold the handles, flexing the control
cables to prevent cable damage.
7. Store the mower in a shed or other dry area, pro-
tected from weather.
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
®
avail-
able 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 con-
tainer. 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.
