Operation
If you have any problems operating your trash pump, please
contact your local Briggs & Stratton service center.
Safe Operating Considerations
Clearances and Air Movement
Place trash pump outdoors in an area that will not
accumulate deadly exhaust gas. DO NOT place trash pump
where exhaust gas (A) could accumulate and enter inside or
be drawn into a potentially occupied building. Ensure
exhaust gas is kept away from any windows, doors,
ventilation intakes, or other openings that can allow exhaust
gas to collect in a confined area. Prevailing winds and air
currents should be taken into consideration when positioning
trash pump.
What is “Head”?
Head refers to the height of a column of water that can be
delivered by the discharge of the pump.
Suction Head is the vertical distance between the center of
the pump and the surface of the liquid on the suction side of
the pump. May also be referred to as “suction lift”. The
atmospheric pressure of 14.7 psi at sea level limits suction
head lift to less than approximately 26 feet for any pump.
Discharge Head is the vertical distance between the pump’s
discharge port and the point of discharge, which is the liquid
surface if the hose is submerged or pumping into the bottom
of a tank.
Total Head is the sum of the suction head value plus the
discharge head value.
As water pumping height increases, pump output decreases.
The length, type, and size of the suction and discharge hoses
can also significantly affect pump output.
It is important for the suction operation to be the shorter
part of the total pumping action. This will decrease the
priming time and improve pump performance by increasing
the discharge head.
Suction head is a maximum of 25 feet and discharge head
should be a maximum of 92 feet. Total head can not be more
than 117 feet as shown on next page.
Move Trash Pump to Safe Operating Location
For best pump performance, locate the pump on a flat, level
surface as close as possible to the water to be pumped.
Secure trash pump to avoid tipover. Use hoses that are no
longer than necessary.
IMPORTANT: Direct open end of discharge hose away from
home, electrical devices or anything not desired to get wet.
WARNING
Exhaust heat/gases can ignite combustibles,
structures or damage fuel tank causing a fire.
• Keep at least 5 ft. (1.5 m) clearance on all sides of trash pump
including overhead.
WARNING
Running engine gives off carbon monoxide, an
odorless, colorless, poison gas.
Breathing carbon monoxide can cause headache,
fatigue, dizziness, vomiting, confusion, seizures,
nausea, fainting or death.

All service and adjustments should be made at least once
each season. Follow the requirements in the Maintenance
Schedule chart above.
NOTE: Once a year you should clean or replace the spark
plug and 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.
Trash Pump Maintenance
Maintenance consists of keeping the trash pump clean. Store
the unit in a clean dry environment where it will not be
exposed to excessive dust, dirt, moisture or any corrosive
vapors. Cooling air slots in the trash pumps engine must not
become clogged with dirt, leaves or any other foreign material.
NOTE: DO NOT use a garden hose to clean trash pumps
engine. Water can enter engine fuel system and cause
problems.
Cleaning
Daily or before use, look around and underneath trash pump
for signs of oil or fuel leaks. Clean accumulated debris from
inside and outside trash 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 25 psi) to blow away dirt. Inspect cooling air
slots and opening on trash 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.
• Follow the instructions in Flush and Drain Trash Pump
and Clean the Impeller.

Storage
The trash pump should be started at least once every seven
days and allowed to run at least 30 minutes. If this cannot be
done and you must store the unit for more than 30 days, use
the following information as a guide to prepare it for storage.
Long Term Storage Instructions
It is important to prevent gum deposits from forming in
essential fuel system parts, such as the carburetor, fuel filter,
fuel hose or tank during storage. Also, experience indicates
that alcohol-blended fuels (called gasohol, ethanol or
methanol) can attract moisture, which leads to separation
and formation of acids during storage. Acidic fuel can
damage the fuel system of an engine while in 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 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. The engine and fuel can then be stored up to
24 months.
If gasoline 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.
Change Engine Oil
While engine is still warm, drain oil from crankcase. Refill
with recommended grade. See Changing Engine Oil in Engine
Maintenance.
Oil Cylinder Bore
• Remove spark plug and pour about 1/2 ounce (15 ml)
of clean engine oil into the cylinder.
• Install spark plug and pull starter handle slowly to
distribute oil.
Trash Pump
1. Drain trash pump as described in Flush and Drain Trash
Pump.
2. Clean trash pump as described in Cleaning.
3. Check that openings on trash 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.
4. Store trash pump in clean, dry area.
WARNING
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or
death.
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 trash 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.
WARNING
Unintentional sparking can result in fire or
electric shock.
• NEVER pull starter handle with spark plug removed.
WARNING
Storage covers can be flammable.
• DO NOT place a storage cover over a hot trash pump.
• Let equipment cool for a sufficient time before placing the cover
on the equipment.

Power Ratings: The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers)
code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with
SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are derived at 3600 RPM. Actual gross engine
power will be lower and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given both the wide
array of products on which engines are placed and the variety of environmental issues applicable to operating the equipment, the gas engine
will not develop the rated gross power when used in a given piece of power equipment (actual "on-site" or net power). This difference is due to
a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application
limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and capacity
limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine.
