SSEMBLY
The Inlet Strainer prevents damaging particles from
entering the Utility Pump. Assemble the Inlet Strainer by
snapping its two parts together. (A, Figure 1)
Connect the Inlet Strainer to the end of a 1 1/2" hose
with a Hose Clamp (B).
Place a Gasket (C) onto the Hose Coupling (D) and
secure it to the other end of the hose with a Hose Clamp
(E), before attaching the entire assembly to the pump
intake with a Hose Ring (F).
To attach the outlet hose, connect the hose to the pump
outlet using a Hose Clamp (G), Gasket (H), and Hose
Ring (I).
PREPARING THE UTILITY PUMP FOR USE
Using this Utility Pump for the First Time
If this Utility Pump is being used for the first time, the following few steps are required to prepare it for use.
Step 1 - Add Oil
When new from the package, this Utility Pump contains no oil in the engine crankcase. Add the
correct quantity of oil before operating this Utility Pump for the first time. This Utility Pump requires
engine oil to function. Engine oil is a major factor affecting engine performance and service life. The correct
quantity of oil is equal to the oil capacity of the engine crankcase and is listed below. When replenishing oil
for subsequent use, always determine that this Utility Pump has the correct quantity of oil.
Oil Capacity (fluid oz.) 12.5
Oil Type Recommended SF15W-40
To add oil:
Figure 2
A
1. Confirm that this Utility Pump is on a level surface.
2. Open the Oil Cap (A, Figure 2).
3. Using a funnel, add oil to fill the engine crankcase to the correct
quantity as stated above.
4. Replace Oil Cap.
Step 2 - Add Gasoline
Gasoline and gasoline fumes are highly flammable and explosive. Handling fuel can result in serious
injury or burns.
• Do not fill the fuel tank near a heat, sparks or an open flame. Keep gasoline away from appliance pilot
lights, barbecues, electric appliances, power tools, etc.
• Do not overfill the fuel tank. Always check for fuel spills and immediately wipe them up. Spilled fuel is a fire
hazard and causes environmental damage.
CWUP15 1 ½ Inch Clean Water Utility Pump 7

CWUP15 1 ½ Inch Clean Water Utility Pump 8
To ensure that this Utility Pump runs smoothly, use only FRESH, UNLEADED GASOLINE WITH AN
OCTANE RATING OF 87 OR HIGHER. Unleaded gasoline produces fewer engine and spark plug deposits
and extends the life of the exhaust system.
1. Confirm that this Utility Pump is on a level surface.
2. Unscrew fuel tank cap and set aside. (NOTE: The fuel tank cap may be tight and difficult to unscrew.)
3. Slowly add fresh, unleaded gasoline to the fuel tank. Be careful not to fill the fuel tank above the upper
limit line. The fuel tank capacity for this Utility Pump is listed below. NOTE: Because gasoline can
expand, do not fill the fuel tank to the very top.
4. Securely tighten the fuel tank cap and immediately wipe up any spilled gasoline with a dry cloth.
Fuel Tank Capacity (gals) 0.40
Fuel Type Fresh, Unleaded Gasoline Octane Rating 87 or Higher
STARTING THE UTILITY PUMP
To start this Utility Pump:
1. Confirm that Oil has been properly added.
2. Confirm that Gas has been properly added.
3. Turn the fuel valve to the “on” position.
4. Move the choke lever to the “closed” position.
5. Set the engine switch to the “on” position. (Figure 3)
6. Slowly pull on the recoil starter handle until a slight resistance is felt. Then pull briskly to start the engine.
7. Gently return the cord into the Utility Pump to avoid damage to the starter or housing. Never allow the
cord to snap back.
8. If the engine fails to start, repeat step 6. NOTE: After repeated attempts to start the engine, consult the
troubleshooting guide before attempting again. If problems persist, call 1-888-287-6981, Monday -
Friday, 8 AM - 4 PM Central Time.
9. Once the engine has started and runs for about a minute, move the choke lever approximately half way
towards the “open” position. Wait an additional 30 seconds and then move the choke lever completely
over to the “open” position.
10. Allow this Utility Pump to run for several minutes before beginning the project.
BREAK-IN PERIOD
Breaking in an engine of any size is important to the life of the engine. The first twenty hours of operation is
considered the break-in period for this Utility Pump. For best results and an engine with fewer problems, it is
suggested that:
• Avoid heavy loads during the first twenty hours.
• Do not run the engine at its highest speeds for extended periods.
• Change the engine oil after ten hours of operation during the break-in period only.
