(12/12)

 

California Proposition 65 Warning -- 

This product 

and related accessories contain chemicals known to the 

State of California to cause cancer, birth defects or other 

reproductive harm. 

Hypro Self-Priming Centrifugal Pumps handle big, high- 

capacity, liquid transfer jobs with ease. Use them for 

transferring water, liquid fertilizers, and other chemicals 

compatible with pump materials. Make short work of other 

farm jobs: filling nurse tanks, watering seedbeds, and 

transferring liquids. This self-priming model makes it ideal 

for de-watering applications.

WARNING: Do not pump flammable or explosive fluids 

such as gasoline, fuel oil, kerosene, etc. Do not use 

in explosive atmospheres. The pump should be used 

only with liquids that are compatible with the pump 

component materials. Failure to follow this warning 

can result in personal injury and/or property damage 

and will void the product warranty.

1.  DO NOT EXCEED recommended speed, pressure and 

temperature  (140˚  F)  for  pump  and  equipment  being 

used.

2.  BEFORE SERVICING, drain all liquids from the system 

and flush. Remove the spark plug wire from the spark 

plug before servicing the pump or engine.

3.  Secure the discharge lines before starting the pump. An 

unsecured line may whip, causing personal injury and/

or property damage.

4.  Check hose for weak or worn condition before each 

use. Make certain that all connections are tight and 

secure.

5. Periodically inspect the pump and the system 

components. Perform routine maintenance as required 

(see Maintenance section).

6.  Protect pump from freezing conditions by draining liquid 

and pumping a permanent-type automobile  antifreeze 

containing a rust inhibitor through the system, coating 

the pump interior. A 50% mixture with water is 

recommended.

7.  Do not operate a gasoline engine in an enclosed area.  

Be sure the area is well ventilated.

WARNING: Gasoline is a highly combustible fuel. The 

improper use, handling, or storage of gasoline can be 

dangerous. Never touch or fill a hot engine.

8.  Use only pipe, hose and fittings rated for the maximum 

psi rating of the pump.

9.  Do not use these pumps for pumping water or other 

liquids for human or animal consumption.
