POWER SUPPLY 

         

WARNING:

 YOUR SANDER MUST BE CONNECTED TO A 120V WALL 

OUTLET, WITH

A

MINIMUM 15-AMP. BRANCH CIRCUIT AND USE A     

15-AMP TIME DELAY FUSE OR CIRCUIT BREAKER. FAILURE TO    
CONNECT IN THIS WAY CAN RESULT IN INJURY FROM SHOCK OR 
FIRE. 
 

GROUNDING 

 
Your sander 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 SANDER 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 sander should malfunction or breakdown, grounding provides a path 
of least resistance for electric current, to reduce the risk of electric shock. 
This sander 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 sander is ready to run for 120V             
operation. This machine is intended for use on a circuit that has an outlet 
and a plug which looks like the one illustrated in Fig.1A. 

         

WARNING:

 DO NOT USE A TWO-PRONG ADAPTOR(S) FOR THEY ARE 

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

 
EXTENSION CORDS 

 
The use of any extension cord will cause some loss of power. If you do not 
have a choice, use the table in Fig.1B 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 
sander motor. Refer to Fig.1B for wire length and size.

USING ON/OFF SWITCH WITH REMOVABLE SAFETY KEY 

 
The On/Off switch (A)

Fig.2 is used to turn the sander on and off. 

To turn the sander “On”, move the switch upwards (On position), to 
turn the sander “Off”, move the switch downwards (Off position).  
 
This switch comes with a removable safety key (B) Fig.2. When the   
safety key is removed from the switch and placed in a safe    
location, unauthorized persons or children can’t turn the switch to 
the On position. It is recommended to always remove the safety 
key from the switch whenever the sander is not in use. To remove 
the safety switch, make sure the switch is in the Off position and 
simply pull out the safety key.
