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.
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 FRESH START® fuel stabilizer, available as a liquid
additive or a drip concentrate cartridge.
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.
The engine and fuel can then be stored up to 24 months.
If petrol in the engine has not been treated with a fuel
stabilizer, it must be drained into an approved container.
Then 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.
Change Engine Oil:
While engine is still warm, drain oil from crankcase. Refill with
recommended grade. See Changing Engine Oil in Engine
Maintenance.

Other Storage Tips
WARNING Fuel and its vapours are extremely
flammable and explosive which could cause
burns, fire or explosion resulting in death,
serious injury and/or property damage.
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 vapours.
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.
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, serious injury and/or property damage.
• 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.
