Operation
If you have any problems operating your trash pump, please

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.

Oil
Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF, SG,
SH, SJ or higher. DO NOT use special additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W30 may cause increased oil
consumption. Check oil level more frequently.
NOTE: Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol with
“SJ/CF ENERGY CONSERVING” or higher, is an
acceptable oil at all temperatures. Use of synthetic
oil does not alter required oil change intervals.
Checking Oil Level
Oil level should be checked prior to each use or at least
every 5 hours of operation. Keep oil level maintained.
1. Make sure trash pump is on a level surface.
2. Clean area around oil fill and remove oil fill cap.
3. Verify oil is at the point of overflowing at oil fill opening.
4. Replace and tighten oil fill cap.
Adding Engine Oil

replacement plug. See Specifications.
5. Install spark plug and tighten firmly.
Clean Spark Arrester Screen
If you use your trash pump on any forest-covered, brush-
covered, or grass-covered unimproved land, it must have a
spark arrester. The spark arrester must be maintained in
good condition by the owner/operator.
If the engine has been running, the muffler will be very hot.
Allow the muffler to cool before servicing the spark arrester.
1. Remove spark arrester screen for cleaning and inspection.
2. Inspect screen and replace if torn, perforated or
otherwise damaged. DO NOT use a defective screen. If
screen is not damaged, clean it with commercial solvent.
3. Reattach spark arrester screen to muffler.
Air Cooling System
Over time debris may accumulate in cylinder cooling fins and
cannot be removed without partial engine disassembly. For
this reason, we recommend you have an authorized Briggs &
Stratton 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.
Check Valve Clearance (Model 073018 Only)
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
an authorized dealer check and adjust valve clearance at
250 hours or as recommended (see Maintenance Schedule in
the Maintenance section).
WARNING
Contact with muffler area can result in serious
burns.
Exhaust heat/gases can ignite combustibles,
structures or damage fuel tank causing a fire.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 5 feet (1.5 m) of clearance on all sides of trash
pump including overhead.
• Code of Federal Regulation (CFR) Title 36 Parks, Forests, and
Public Property require equipment powered by an internal
combustion engine to have a spark arrester, maintained in
effective working order, complying to USDA Forest service
standard 5100-1C or later revision. In the State of California a
spark arrester is required under section 4442 of the California
Public resources code. Other states may have similar laws.

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.
