ELECTRICAL INFORMATION

WARNING 

ALL ELECTRICAL CONNECTIONS MUST BE DONE BY A QUALIFIED ELECTRICIAN. FAILURE TO COMPLY MAY RESULT IN        
SERIOUS INJURY! ALL ADJUSTMENTS OR REPAIRS MUST BE DONE WITH THE COMPRESSOR DISCONNECTED FROM THE 
POWER SOURCE. FAILURE TO COMPLY MAY RESULT IN SERIOUS INJURY! 

GENERAL INFORMATION- 120V/240V single phase operation 
 

This air compressor comes with a 120V/240V single phase motor prewired 
for 120V operation. If 240V single phase operation is required, refer to   
section 240V operation below.

 

         

WARNING:

 YOUR COMPRESSOR MUST BE CONNECTED TO A 120V,  

WITH A MINIMUM 15-AMP. BRANCH CIRCUIT. FAILURE TO CONNECT 
IN THIS WAY CAN RESULT IN INJURY FROM SHOCK OR FIRE. 
 

GROUNDING 

Your compressor must be properly grounded. Not all outlets are properly 
grounded. If you are not sure if your outlet is properly grounded, have it 
checked by a qualified electrician. 
 

WARNING:

 IF NOT PROPERLY GROUNDED, THIS COMPRESSOR 

CAN CAUSE ELECTRICAL SHOCK, PARTICULARLY WHEN USED IN 
DAMP LOCATIONS. TO AVOID SHOCK OR FIRE, IF THE POWER CORD 
IS WORN OR DAMAGED IN ANY WAY, HAVE IT REPLACED              
IMMEDIATELY. 
 
If this compressor should malfunction or breakdown, grounding provides a 
path of least resistance for electric current, to reduce the risk of electric 
shock. This cut-off is equipped with a cord having an equipment-grounding 
conductor and grounding plug. The plug must be plugged into an         
appropriate outlet that is properly installed and grounded in accordance 
with all local codes and ordinances. 

 
WARNING: 

TO MAINTAIN PROPER GROUNDING, DO NOT REMOVE OR 

ALTER THE GROUNDING PRONG IN ANY MANNER. 
 

120V OPERATION 

As received from the factory, your compressor is ready to run for 120V 
operation. This machine is intended for use on a electrical circuit that has 
an outlet and a plug which looks like the one illustrated in Fig.1. 

         

WARNING:

 DO NOT USE A TWO-PRONG ADAPTOR FOR THEY ARE 

NOT IN ACCORDANCE WITH LOCAL CODES AND ORDINANCES. 
NEVER USE IN CANADA. 

 
240V OPERATION 
WARNING!

 It is recommended to contact your authorized service centre or 

qualified electrician to change the motor connections from 120V to 240V, 
replace motor reset and replace the power cord to a 240V model. The use 
of an extension cord is generally not recommended for 220V-240V         
operation.

FIGURE 2

EXTENSION CORDS 

 
The use of any extension cord will cause some loss of power. IT 
IS RECOMMENDED TO USE A LONGER AIR HOSE INSTEAD 
OF AN EXTENSION CORD. If you do not have a choice, use the 
chart in Fig.2 to determine the minimum wire size    
(A.W.G-American Wire Gauge) extension cord needed. Use only 
3-wire extension cords which have 3-prong grounding type plugs 
and 3-hole receptacles which accept the tool’s plug. 
 
For circuits that are further away from the electrical circuit box, the 
wire size must be increased proportionately in order to deliver 
ample voltage to the compressor motor. Refer to Fig.2 for wire 
length and size.
