Frequently Asked Questions - XP702HP DuroMax

What type of oil should I use in the XP702HP water pump?

Use SAE 10W-30 engine oil. For the first 6-8 hours (break-in period), use conventional oil. After break-in, synthetic 5W-30 may be used for cold weather starting. Oil capacity is 20 fl oz (0.6 L).

How do I prime the water pump before starting?

Remove the priming port plug on top of the discharge port, fill the pump casing with water, then fill the suction hose with water until full. Never run the pump dry as it can damage internal parts.

What is the maximum flow rate and lift height?

The XP702HP delivers up to 70 GPM (gallons per minute) and can lift water up to 252 feet vertically (static lift). Suction distance is up to 23 feet.

How do I store the water pump for more than 30 days?

Run the engine dry by shutting off the fuel valve and letting it stall. Empty the gas tank completely. Remove the spark plug, add 2 tablespoons of 10W-30 oil into the cylinder, pull the recoil to lubricate, then reinstall the spark plug. Store in a cool, dry area.

What kind of fuel does the XP702HP require?

Use fresh, unleaded gasoline with an octane rating of 87 or higher. Do not use oil/gasoline mixtures. Avoid ethanol-blended fuels if possible; if used, add fuel stabilizer for storage.

Why does the engine start then shut off after a short time?

This is often caused by low oil level triggering the low oil shutoff sensor. Check and add oil. Other causes: old/contaminated fuel, or operating on an incline over 15 degrees. Check oil and fuel first.

How do I check and change the oil?

To check: place pump on level surface, remove dipstick, wipe clean, reinsert without screwing, then check oil level on stick. To change: drain oil by removing the 12mm drain plug under the crankcase, replace plug, fill with 20 fl oz of 10W-30 oil.

What is the warranty on the DuroMax XP702HP?

DuroMax offers a 3-year parts warranty for residential use, and 1-year for commercial use. It covers defects in materials and workmanship. Exclusions include normal wear, misuse, and aftermarket parts.

Can I use the water pump indoors?

Never use indoors. The engine produces carbon monoxide, a poisonous gas that is odorless and colorless. Always operate outdoors in a well-ventilated area, away from windows, doors, and vents.

What size hoses does the pump accept?

The inlet port accepts a 2-inch suction hose. The discharge port accepts both 1.5-inch and 2-inch discharge hoses (with adapters). Use appropriate DuroMax hoses for best performance.

WATER PUMP SETUP

Proper setup of your water pump will get you going as soon as possible while making sure you and your equipment are safe and cared for.

Step 1 - Adding Oil

The water pump requires engine oil to operate properly. The water pump, when new from the package, contains no oil in the crankcase*. You must add the proper amount of oil before operating the water pump for the first time. This amount is equal to the oil capacity of the engine crankcase:

Model Number XP702HP
Engine Oil Capacity 20	fl. oz. (0.6 L)

WARNING: Do not apply engine oils with additives or 2-stroke gasoline engine oils; they don't have enough lubrication and may shorten the engine's service life.

Engine oil recommended: SAE 10W-30.

Viscosity varies with regions and temperatures. Choose your oil viscosity using the chart to the left.

* A small amount of oil from factory testing may be present on arrival.
* Synthetic oil may be used after the 8 hour initial break-in period. Using synthetic oil does not increase the recommended oil change interval. Full synthetic 5W-30 oil will aid in starting in cold temperatures < 5^ (41°F).

Add oil

a. Make sure the water pump is on a level surface.
b. Unscrew the oil filler/dipstick cap from the engine.
c. Using a funnel, add the appropriate amount of oil into the crankcase. You will know the crankcase is full when the oil level has reached the lower lip of the opening you have just poured the oil into.
d. Replace the oil filler cap.

Add gasoline

a. Make sure the water pump is on a level surface.
b. Unscrew gas cap and set aside (NOTE: the gas cap may be tight and hard to unscrew).
c. Slowly add unleaded gasoline to the fuel tank. Be careful not to overfill. The fuel gauge on the top of the gas tank indicates how much gasoline is in the water pump gas tank.

d. Replace fuel cap and wipe up any spilled gasoline with a dry cloth.

Model Number XP702HP

Fuel Tank Capacity 0.95 US Gal.

WARNING: Gas can expand. Do not fill the gas tank to the very top. Leave a minimum of 1.5 in open space. Gasoline and gas fumes are highly flammable. Do not fill the tank near an open flame. Always check for fuel spills.

IMPORTANT:

• To ensure that the engine runs smoothly use only FRESH, UNLEADED GAS WITH AN OCTANE RATING OF 87 OR HIGHER.
• Never use an oil/gasoline mixture. Never use old gas.
- Avoid getting dirt or water in the fuel tank.
Gas can age in the tank and make it hard to start up the water pump in the future.
• Never store water pump for extended periods of time with fuel in the tank.

Check the oil

The water pump is equipped with an automatic shutoff to protect it from damage due to low oil. Nonetheless, you should check the oil level of the engine before each use to ensure that the engine crankcase has a sufficient amount.

To check the oil level:

a. Make sure the water pump is on a level surface.
b. Unscrew the oil filler/dipstick cap.
c. With a dry cloth, wipe the oil off of the stick on the inside of the cap.
d. Insert the dipstick as if you were replacing the cap and then remove it again. There should now be oil on the stick. If there is no oil on the stick, or oil only at the very end of the stick, you should add oil until the engine crankcase is filled (see "Adding Oil" portion of the "Maintenance" section).

e. Be sure to replace the cap when finished checking oil.

Model Number XP702HP

Check the Gas Level

Close-up of a mechanical component with a red internal part and a metallic chain attached to a blue surface (no visible text or symbols)

Check fuel level

If running the engine on gasoline check to see that there is sufficient gasoline in the fuel tank. The gasoline level should always be under the red fuel level indicator located on the bottom of the fuel filter cup.

WARNING: Gasoline and gasoline fumes are highly flammable.

• Do not fill the tank near an open flame.
  • Always allow the engine to cool for several minutes before refueling.
• DO NOT overfill the fuel tank. Fuel expands when shaken or heated. ALWAYS leave 1^1/2 space or more at the top of the tank.
• ALWAYS use fresh fuel or stabilized fuel. Old gasoline (older than 30 days) can cause permanent damage to the fuel system.
  • Always check for fuel spills.
