2.

An overload may have caused the thermal overload protector in 
motor  to  shut  off  current.  Be  sure  sander  is  off,  then  find  and 
eliminate cause for overload.   

 

Some motors are equipped with manual Re-Set thermal overload 
protector wait at least 30 minutes, then firmly press Re-Set button 
on motor with eraser end of pencil or a small blunt dowel. After 
approximately  30  minutes  you  should  be  able  to  hear  or  feel 
overload  protector  click  in  when  pushed  to  reset.  After  Re-Set 
clicks in, turn the main switch ON and start (Stop/Start switch) the 
machine.  

 

 

 
 
 
 

 

 
 
 
 
 
 

After this procedure, the motor should run normally. If the motor 
has no Re-Set button, wait 30 minutes that the engine would shrink. 
After this time, the engine should reset itself.  

 

If you believe that the motor presents an anomaly, please contact 
Landis customer service at 1 800 634-0806.
