PRE-START CHECKLIST (continued) 

3.

INSPECT/CLEAN/CHANGE INTAKE ELEMENTS ON A REGULAR BASIS 
The ingestion of dirt into the pump and engine is the primary cause of premature wear. Pay special 
attention to the intake filters. Check intake filters daily. 

4.

USE LONGER PROPERLY SIZED AIR HOSE RATHER THAN EXTENSION CORDS 
If an extension cord must be used, please refer to the chart on the following page for the proper gauge 
and maximum length that can be used. The use of inadequately sized air hose will also lead to frictional 
pressure drops that could affect the proper performance of your air tools.  
 

5.

DO NOT USE A GENERATOR AS THE POWER SOURCE 
Air compressors use inductive motors that require 3-5 times the full-load amp draw to properly start. 
Most generators will not provide the wattage needed to properly start this type of electric motor. 
 

6.

CHECK TENSION OF BOLTS, BELTS, AND HARDWARE ON A REGULAR BASIS  

      Operation of any equipment with loose bolts and/or fittings will lead to excessive vibration                    
      and the premature failure of the compressor system control components. 

7.

MAINTAIN RUBBER VIBRATION PADS 
Excessive vibration is a major cause of premature compressor failure. Always maintain the rubber 
vibration pads located beneath tank assembly. Operation without them will void your warranty. 

 
8.

DRAIN MOISTURE FROM AIR TANK DAILY 
Water is a natural byproduct of compressed air. Drain air tank(s) after each use to combat internal tank 
corrosion. Keep drain valve(s) closed if storing compressor for any length of time.
