3.0 - PRE-OPERATING PROCEDURE
Inspect all components for damage and to ensure that none are missing. If
you require a replacement, do not operate this tool until all parts are present
and in proper working order.
Do not modify or create accessories for this equipment. Using modified
components may result in damage and may void the warranty. Contact
customer service if you suspect that this equipment has been tampered with.
3.1 - Engine Oil Check
1. Ensure the Trash Pump is on a level surface.
2. Inspect engine oil:
• Take out the dipstick and clean it with a dry towel.
• Check the oil level by reinserting the oil ller cap without rotating it.
Remove the oil ller cap and examine the oil level. If the oil level is at
or below the lower level, rell the oil to the upper limit mark. (10W30)
Reinsert the oil ller cap and tighten securely.

12
3. If necessary, add engine oil - Open oil inlet located opposite the recoil
starter handle. Remove the dipstick and pour in the supplied oil with a
funnel. Do not operate without oil.
Reservoir can hold maximum 20 fl.oz of 10W30 oil - do not over fill.
Engine oil is a major factor affecting engine performance and service life. Non-
detergent or vegetable oils are not recommended.
3.2 - Fuel Level Check
1. Check the fuel level by opening the tank and visually inspecting
2. Refuel if level is too low. Tighten the fuel tank cap securely after relling

13
Gasoline is highly flammable and explosive under certain conditions. Refuel in
a well-ventilated area with the engine stopped. Do not smoke or allow open
flames or sparks in the area where the Trash Pump is being refueled or where
gasoline is stored. Do not overfill the tank. Be careful not to spill fuel when
refueling. Wipe up any spilled gasoline and let the area dry before starting the
engine. Gasoline substitutes such as gasohol are not recommended. They
may be harmful to the fuel system components
3.3 - Check the Air Filter
1. Loosen the knob and remove the air lter cover. Remove the air lter
element and inspect for cleanliness.
2. Clean the air lter element with soap and water or solvent. Squeeze dry
and then soak in clean engine oil.
3. Squeeze out all excess oil and reinstall. Replace the element if it is
damaged.
Check the air filter according to the maintenance schedule. Always inspect
the air filter before using the Trash Pump. Clean Air Filter every 3 months or
after 50hrs of operation according Section 5.4: Air Filter Service procedure.

14
3.4 - Hose Connections
1. Insert adapters into each end of the suction and discharge hoses.
2. Attach O-Rings to the adaptors.
3. Tighten the hose clamp around the discharge hose.
4. Insert strainer into the suction hose and tighten the hose clamp around
the hose.
5. Insert adapters into the appropriate pump ttings. Avoid sharp bends in
the hoses and do not place heavy objects on top.

15
4.0 - OPERATION
4.1 - Pump Placement
Placement is an important step in safely operating this product.
1. Refer to diagram for proper placement instructions.
2. Ensure that the suction head is less than the discharge head.
3. Increasing the discharge head will decrease output.
4. Ensure pump is primed to minimize the suction head.
Suction head is the height to which a pump can raise water on the suction
side, measured from the water level in the sump. Discharge head is the vertical
distance between the intake level of the water pump and the level at which
it discharges water freely. Total head is the sum of the suction and discharge
head.

16
4.2 - Priming Water
Make sure to prime the pump with water prior to operating it. Priming creates
a vacuum that helps to start the flow of water.
1. Unscrew the primer cap and insert the neck of the water container into
the opening. Gradually tilt until the reservoir is full.
2. Tighten the cap back on.
3. In case of dry operation (running the pump without priming), stop the
engine immediately and allow it to cool before following the priming
procedure.
Do not operate without priming. Doing so will overheat the engine and result
in damage to the system. Ensure that the priming water does not contain
debris.
4.3 - Starting the Trash Pump
RECOIL START METHOD
1. Rotate the fuel valve lever to ON position.
2. If the engine is cold: Push the choke lever to the CLOSE position out to
close the choke.

17
3. Grasp the recoil starter handle and pull it until the engine starts.
Do not allow the recoil starter to snap back. Return it slowly by hand
4. Push the choke lever to the OPEN position as the engine warms up. The
choke is used to provide the proper mixture when the engine is cold. It
can be opened and closed manually by moving the choke lever to the
closed position to enrich the mixture for cold starting.
5. After 5 minutes, slowly push the throttle lever to the OPEN position.
Engine RPMs will increase until engine reaches its stable running speed.
If the engine backfires or does not start repeated attempts, contact customer
support and do not attempt to use the Trash Pump.
4.4 - Stopping the Engine
1. Return the throttle lever to the IDLE position (towards the right)
2. Turn the engine switch to the OFF position
3. Turn the fuel valve to the OFF position
In an emergency, the engine can be quickly stopped by turning the engine
switch to the OFF position.

5.3 - Oil Change and Oil Drainage
Used motor oil can cause skin irritations if left in long-tern contact with skin.
Wash hands thoroughly with soap and water after handling oil.
Do not dispose of used oil in drains or on soil. Local service shops provide
environmentally-friendly disposal methods.
1. Stop the engine and remove oil ller cap.
2. Place a pan under the engine.
3. Remove the oil drain screw and allow the oil to completely drain into the
pan.
4. Reinstall drain screw before lling the engine with fresh oil. Do not
overll oil reservoir. Use a funnel to prevent spillage.
5. Reinstall the ller cap and tightly fasten it.

5.4 - Air Filter Service
Using gasoline or other flammable solvents can cause a fire or explosion. Do
not use these to clean the air filter.
Do not operate this product without an air filter.
1. Unscrew the air lter cover.
2. Remove the lter element and wash with soap and water.
