Alpha Tool.Com.HK Limited Polisher VSP230 User Manual

							21
Periodic maintenance is done to check the tool and to minimize down time.  These checks 
are done based on hours of operation and operating conditions.  Operating condition can 
vary depending on the work surface and job being preformed.  If the tool is not used for a 
long period of time the carbon brushes should be checked and the commutator cleaned, 
before putting the tool back into operation.
  BEARINGS AND GEARS
To minimize your tool’s down time and expensive tool repairs, it is recommended to send 
the tool back to an Alpha
® Repair Center after about 300 to 400 hours of operation or every 
second carbon brush set change.  The bearings should be replaced and the gears should be 
checked.  If your tool starts to sound differently, this could be an indication of a worn bearing; 
continuing to use the tool in this condition could result in over heating or motor failure.
  CARBON BRUSH REPLACEMENT 
Carbon brushes wear out over time, based on the polisher usage. If a carbon brush is worn 
out, it may cause the motor to malfunction or fail to run. Whenever the length of the carbon 
brush reaches the wear limit, replace with a new set.
NOTE - To maintain even wear, both brushes should be replaced at the same time.
The carbon brushes in this polisher are located underneath the Rear Cover (Part  #  210053) 
as shown in Figure 23.

							11.  You can also remove the carbon brush by 
removing the screw and pulling the holder out 
with a pair of needle nose pliers.
12.  With the carbon brush holder removed, you can 
check and clean the armature commutator.  The 
commutator is the contact points that the carbon 
brushes ride on when the motor is running.
NOTE:  Each polisher has 2 carbon brushes located on opposite sides of each 
other.  After the replacement of the two brushes, assemble the polisher by reversing 
disassembly procedure.
13.  Check the carbon brush for wear.  Replace if worn down to a 6.4mm.
14.  Blow dust off of the spring and check for proper tension.
15. Remove the old carbon and disconnect the wire terminal wire.  If the inside of the holder 
is fi lled with dust, clean before installing the new carbon brush.  Upon installation of 
the new carbon brush, make sure the twisted wire is in the slot and behind the wire 
terminals on holder as in the photo above.

16.  The commutator should be clean and shiny; if it is dull and black, you can clean it with 
a commutator cleaning stone.
17.  To clean the commutator, press the commutator cleaning stone against the commutator 
and rotate the armature by turning the spindle shaft by hand.  Continue for a minute 
or until commutator is clean and shiny.
18.  Reconnect the power wire, ensuring that the wire path is correct.   Reinstall the carbon 
brush holder into the slot on motor housing and slide in until the tab for the screw hits 
the stop.  Install the screw using light pressure to prevent it from stripping.
19.  After both carbon brushes have been replaced you can reassemble the rear cover.  
Make sure the power wires are in the tool to prevent pinching of the wires.
