the top cover (B).
REPLACING THE SANDING DISC
See the section “ABRASIVE DISC” in the “ASSEMBLY” section of this manual.
Disconnect the machine from the power source!
OVERLOAD PROTECTION
The motor supplied with your sander is equipped with a
reset overload relay button (A) Fig. 70. If the motor shuts
off or fails to start because of overloading (sanding too
heavy, using a worn sanding belt or disc, using the
sander beyond its capacity), or low voltage, turn the
power switch to the “OFF” position. Let the motor cool
three to five minutes and push the reset button (A) Fig.
70. Start the motor.
