The motor supplied with your sander is equipped with a 
reset overload relay button (A) Fig. 70. If the motor shuts 
off or fails to start because of overloading (sanding too 
heavy, using a worn sanding belt or disc, using the 
sander beyond its capacity), or low voltage, turn the  
power switch to the “OFF” position. Let the motor cool 
three to five minutes and push the reset button (A) Fig. 
70. Start the motor.
