Inspect Muffler and Spark Arrester
Inspect the muffler for cracks, corrosion, or other damage.
Remove the spark arrester, if equipped, and inspect
for damage or carbon blockage. If replacement parts
are required, make sure to use only original equipment
replacement parts.
WARNING Exhaust heat/gases could ignite combustibles,
structures or damage fuel tank causing a fire, resulting
in death or serious injury. Contact with muffler area
could cause burns resulting in serious injury.
• Do not touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 1.5 m (5 ft) of clearance on all sides of water
pump including overhead.

Air Cooling System
Over time debris may accumulate in cylinder cooling
fins and cannot be observed without partial engine
disassembly. For this reason, we recommend you have
a qualified service dealer clean the cooling system
(A) per recommended intervals (see Maintenance
Schedule in beginning of Maintenance section). Equally
important is to keep top of engine free from debris. See
Clean Debris.
Carburetor Adjustment
The carburetor on this engine is low emission. It is
equipped with a non-adjustable idle mixture valve.
Top speed has been set at the factory. If adjustment is
required, see an authorized service dealer.
CAUTION Excessively high operating speeds could
result in minor injury.
Excessively low speeds impose a heavy load.
• DO NOT tamper with governor spring, links or other parts
to increase engine speed. Water pump supplies correct
rated pressure and flow when running at governed speed.
• DO NOT modify water pump in any way.
Storage
If the water pump cannot be used at least once every
30 days or you must store the unit for more than 30
days, use the following information as a guide to
prepare it for storage.
Protect Fuel System
Fuel Additive
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.

There is no need to drain petrol 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 petrol 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.
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 can ignite fuel vapors.
WHEN DRAINING FUEL
• Turn water pump 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.
• DO NOT light a cigarette or smoke.
Change Engine Oil
While engine is still warm, drain oil from crankcase.
Refill with recommended grade. See Changing Engine
Oil in Engine Maintenance.
Clean Water Pump
1. Drain water pump as described in Drain and Flush Water
Pump.
2. Clean water pump as described in Cleaning.
3. Check that openings on water pump are open
and unobstructed.
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. Replace fuel can if it starts to rust. Contaminated fuel will
cause engine problems.
3. Cover unit 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 water pump.
• Let equipment cool for a sufficient time before placing the
cover on the equipment.
4. Store water pump in clean, dry area.
