Inspect Spark Arrester
Inspect spark arrester for damage or carbon blockage. If
damage is found or cleaning is needed, see a Briggs &
Stratton Authorized Service Dealer.
WARNING! Contact with muffler area could
cause burns resulting in serious injury.
• Pay attention to the warnings on the generator.
• Do not touch hot parts.
Check Valve Clearance
Regular valve clearance check and adjustment will
improve performance and extend engine life. This
procedure cannot be done without partial engine
disassembly and the use of special tools. For this
reason we recommend that you have a Briggs & Stratton
Authorized Service Dealer check and adjust valve
clearance at recommended intervals (see Maintenance
Schedule).

Storage
If storing the unit for more than 30 days, use the following
guidelines to prepare it for storage.
Protect 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.
There is no need to drain gasoline from the engine if a
fuel stabilizer is added according to instructions. Run the
engine outdoors 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 outdoors until it stops from lack of fuel.
The use of a fuel stabilizer in the storage container is
recommended to maintain freshness.
WARNING! Fuel and its vapors are
extremely flammable and explosive
which could cause burns, fire or
explosion resulting in death or serious injury.
• When storing fuel or equipment with fuel in tank, store
away from furnaces, stoves, water heaters, clothes
dryers or other appliances that have pilot light or other
ignition source because they could ignite fuel vapors.
• When draining fuel, turn generator engine off and let it
cool at least 2 minutes before removing fuel cap.
• Loosen cap slowly to relieve pressure in tank.
• Drain fuel tank outdoors.
• Keep fuel away from sparks, open flames, pilot lights,
heat, and other ignition sources.
Change Engine Oil
While engine is still warm, drain oil from crankcase. Refill
with recommended grade. See Changing Engine Oil.
Other Storage Tips
1. DO NOT store fuel from one season to another
unless it has been treated as described in Protect
Fuel System.
2. Store generator in clean, dry area and cover with a
suitable protective cover that does not retain moisture.
WARNING! Storage covers could cause a fire
resulting in death or serious injury.
• Do not place a storage cover over a hot generator.
• Let equipment cool for a sufficient time before placing
the cover on the equipment.
