CAUTION 

Make sure the brush wire is capable of moving 
freely in the slot in the brush box.  Failure to do 
so may cause the brush to get stuck in the brush 
box and will result in poor motor performance. 

 

  

WARNING

 

The motor frame ground wire is connected to 
the same screw as one of the brush wires.  If the 
ground wire was removed, make certain that it 
is securely reconnected.  Failure to do so may 
result in personal injury.

they are uncoiled or otherwise damaged, record the product type and serial 
number from the motor nameplate. Contact your supplier, any Authorized
