Oil Funnel 1 piece

Assembly
Rev 64023-20090226 7
Assembly
Your semi-trash pump requires some
assembly. This unit ships from our factory
without oil. It must be properly serviced
with fuel and oil before operation.
If you have any questions regarding the
assembly of your semi-trash pump, call our
help line at 1-877-338-0999. Please have
your serial number and model number
available.
Remove the Semi-trash pump
from the Shipping Carton
1. Set the shipping carton on a solid, flat
surface.
2. Remove everything from the carton
except the semi-trash pump.
3. Carefully cut each corner of the box
from top to bottom. Fold each side flat
on the ground.
Add Engine Oil
CAUTION
DO NOT attempt to crank or start the engine
before it has been properly filled with the
recommended type and amount of oil. Damage
to the semi-trash pump as a result of failure to
follow these instructions will void your warranty.
1. Place the semi-trash pump on a flat,
level surface.
2. Remove oil fill cap/dipstick to add oil.
3. Add 0.63 qt (0.6 L) of oil and replace oil
fill cap/dipstick.
4. Check engine oil level daily and add as
needed.
CAUTION
The engine is equipped with a low-oil-shutoff and
will stop when the oil level in the crankcase falls
below the threshold level.
NOTE
Check oil often during the break-in period. Refer
to the Maintenance section for recommended
service intervals.
Add Fuel
1. Use clean, fresh, regular unleaded fuel
with a minimum octane rating of 85.
2. DO NOT mix oil with fuel.
3. Clean the area around the fuel cap.
4. Remove the fuel cap
5. Slowly add fuel to the tank. DO NOT
overfill. Allow approximately1/4 inch of
space for fuel expansion.
6. Screw on the fuel cap and wipe away any
spilled fuel.
CAUTION
Use regular unleaded gasoline with a minimum
octane rating of 85.
DO NOT mix oil and gasoline.
Fill tank to approximately1/4” below the top of
the tank to allow for fuel expansion.
DO NOT fill fuel tank indoors.
DO NOT fill fuel tank when the engine is running
or hot.
DO NOT overfill the fuel tank.
DO NOT light cigarettes or smoke when filling the
fuel tank.

Operation
8 Rev 64023-20090226
Operation
Semi-Trash Pump Location
Place the semi-trash pump in a well-
ventilated area. DO NOT place the semi-
trash pump near vents or intakes where
exhaust fumes could be drawn into occupied
or confined spaces. Carefully consider wind
and air currents when positioning semi-
trash pump.
This semi-trash pump must have at least five
feet of clearance from combustible material.
Leave at least three feet of clearance on all
sides of the semi-trash pump to allow for
adequate cooling, maintenance and
servicing.
Place the pump on a level surface free from
any obstructions or potential hazards. The
pump should be placed close to the water
level to ensure maximum pump
performance.
Pump output will be affected by the type,
length, and size of the suction and discharge
hoses. The pumping height, also known as
the total head, is the distance from the water
level to the point of discharge. As this
distance increases, pump output decreases.
The discharge capacity is greater than the
suction capacity. Therefore, it is important
that the suction head is less than the
discharge head.
The time required to draw water from the
source to the pump (self-priming time) can
be decreased by minimizing the suction
head.
Connecting a Hose Kit (not
included)
Hoses are not included the following are
examples of how to connect the hose to the
water pump. Attach and thread the
connector to the threaded flange (Figure 1).
NOTE
Both the intake and discharge ports are 2 in.
NPT. Please insure the connectors to the suction
and discharge hose are 2 in. NPT threaded.
Figure 1
Slide the flexible, outlet hose over connector
and secure with a hose clamp (Figure 2).
Figure 2

Operation
Rev 64023-20090226 9
Wrap the 2” NPT inlet clockwise with
plumber tape (Figure 3) to ensure a tight fit.
Carefully thread the male connector to the
intake port.
Figure 3
WARNING
DO NOT run the pump dry.
Running the pump dry can destroy the pump
seals and will void the warranty.
If the pump was running while dry, stop the
engine and allow it to cool thoroughly before
filling the chamber with water.
Starting the Engine
1. Make certain the semi-trash pump is on
a flat, level surface.
2. Flip engine switch to “ON” position
3. Rotate the fuel valve to the “ON”
position (to the left). See image below
4. Move the choke lever (Item A) to the
“Choke” position (to the left).
5. Pull the starter cord slowly until
resistance is felt and then pull rapidly.
6. As engine warms up, move the choke
lever to “Run” (to the right).
7. Move the throttle lever (Item B) to the
“Fast” position.
NOTE
If the engine starts but does not run make
certain that the semi-trash pump is on a flat,
level surface. The engine is equipped with a low
oil sensor that will prevent the engine from
running when the oil level falls below a critical
threshold.
Pump performance can be adjusted using
the throttle. To decrease pump output, slide
the throttle to the right. To increase it, slide
the throttle to the left.
Stopping the Engine
1. Turn the ignition switch to the “Off”
position.
2. Rotate the fuel valve to the “Off”
position.
3. Allow the engine to cool thoroughly.
4. Remove the cap from the cooling pump
chamber and allow it drain completely.
