 GROUND FAULT CIRCUIT INTERRUPTER  (GFCI)
  A Ground Fault Circuit Interrupter is built in line with the power supply cord.
  The GFCI goes OFF when water enters inside the tool’s housing preventing the operator 
from electric shocks.
  When the GFCI goes OFF, this could be the result of water entering the polisher 
housing.
       
1. Turn OFF the power switch, disconnect polisher from power supply and blow dry 
air inside the motor cover through the air vents.
2. Re-connect power supply and press the GFCI reset button. The polisher is ready 
to start working once the reset button is pressed down. 
 TESTING IN-LINE GFCI UNIT (Before Each Use Of The Polisher)

MAINTENANCE
 DAILY:
Before servicing polisher turn the switch off and disconnect from power supply.
1.  Before daily start-up inspect polisher, power cord, GFCI, and water feed system for 
loose hardware and/or damage.
2.  If damage has occurred, repair affected areas before use.
3.  After daily use of the tool, clean exterior and drain center water-feed system.
 PERIODIC:
Carbon brushes wear out over time base 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  #  52) 
as shown in Figure 13.
