general recommendations
Regular maintenance will improve the performance and
extend the life of the water pump. See any authorized Briggs
& Stratton dealer for service.
The water pump's warranty does not cover items that have
been subjected to operator abuse or negligence. To receive
full value from the warranty, the operator must maintain the
water pump as instructed in this manual.
Some adjustments will need to be made periodically to
properly maintain your water pump.
All service and adjustments should be made at least once
each season. Follow the requirements in the Maintenance
Schedule chart above.
NOTICE Once a year you should clean or replace the spark
plug and clean or replace the air filter. A new spark plug and
clean air filter assure proper fuel-air mixture and help your
engine run better and last longer.

emissions control
Maintenance, replacement, or repair of the emissions
control devices and systems may be performed by any
non-road engine repair establishment or individual.
However, to obtain "no charge" emissions control service, the
work must be performed by a factory authorized dealer. See
the Emissions Warranty.
water Pump Maintenance
Maintenance consists of keeping the water pump clean.
Store the unit in a clean dry environment where it will not be
exposed to excessive dust, dirt, moisture or any corrosive
vapours. Engine cooling air slots must not become clogged
with dirt, leaves or any other foreign material.
NOTICE Do Not use a garden hose to clean engine. Water
can enter engine fuel system and cause problems.
cleaning
Daily or before use, look around and underneath water pump
for signs of oil or fuel leaks. Clean accumulated debris from
inside and outside water pump. Keep linkage, spring and
other engine controls clean. Keep area around and behind
muffler free from any combustible debris. Use low pressure
air (not to exceed 1.7 bar (25 psi)) to blow away dirt. Inspect
cooling air slots and opening on water pump. These openings
must be kept clean and unobstructed.
Engine parts should be kept clean to reduce the risk of
overheating and ignition of accumulated debris.
• Use a damp cloth to wipe exterior surfaces clean.
• Use a soft bristle brush to loosen caked on dirt or oil.
• Use a vacuum cleaner to pick up loose dirt and debris.
Remove silt and sludge buildup in pump body:
• Open priming plug and remove drain plug.
• Flush internal components of pump with clean water.
NOTICE Improper treatment of water pump could damage it
and shorten its life.
• DO NOT insert any objects through cooling slots.
