IMPORTANT OPERATING CONDITIONS

   

 

Failure to comply with any of these conditions invalidates the warranty

1.  Prior to initial operation, add oil to crank

-

case so that oil level is between the two lines 

on the oil dipstick. DO NOT OVERFILL.  

Use Giant Recommended Oil 

P/N 01154, or the equivalent to 

SAE 85-90W Industrial Gear Lube. 

Crankcase oil should be changed after the 

first 50 hours of operation, then at regular 

intervals of 500 hours or less depending on 

operating conditions.

IMPORTANT:  

When operating in high hu-

midity or  wide temperature fluctuations, oil 

must be changed if condensate or frothy oil 

occurs in crankcase.

2.  Pump operation must not exceed 

rated pressure, volume, or RPM. A pres

-

sure relief device must be installed in 

the discharge of the system

.

3.  Acids, alkalines, or abrasive fluids 

cannot be pumped unless approval in 

writing is obtained before operation from 

Giant Industries, Inc.

4.  Run the pump dry approximately 10 

seconds to drain the water before expo-

sure to freezing temperatures.
