Removal

  

The  vacuum  motor  brush  is  a  quick-wear  item  that  should  be 

inspected and replaced periodically. 

 

1.  Make sure solution tank and recovery tank are empty. Excess 

weight  in  the  tanks  can  throw  off  the  balance  of  machine  when 

scrubbing deck is removed from machine. 

 

 

2.  Remove vacuum motor according to procedures described on 

previous page. 

 

 

3.  Remove two screws (B) that fix the brush cover (A). 

 

 

4.  Remove screws (C) that fix the brush holder (D) to the motor. 

 

 

5.  Tilt brush holder (D) out of its pocket and slide it away from the 

motor. 

 

 

6.  Examine commutator bars (E), if any are damaged or missing, 

replace the motor.
