This may be because the motor or frame have become loose from the base, or that the V-belt has stretched out due to the machine being used.
ADJUSTMENTS THE MACHINE MUST NOT BE PLUGGED IN AND THE POWER SWITCH MUST BE IN THE 'OFF' POSITION UNTIL ASSEMBLY IS COMPLETE. REPLACING THE V-BELT CONTINUED FROM PAGE 13 NOTE: Replacing the V-Belt requires that the Belt Cover, bottom Base Cover, and whole Sanding Disc Assembly be removed in order to gain access to the drive shafts and pulleys. 1.
