ELECTRICAL DOUBLE INSULATION EXTENSION CORDS Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded. When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the tool will draw.

OPERATION SANDING BELT TO INSTALL/CHANGE SANDING BELT See Figures 5 - 6. LIFT BELT TENSION RELEASE LEVER TO REMOVE SANDING BELT n Unplug the sander. n Position sander as shown.

Belt tension must be released in order to install and remove sanding belt: n Release belt tension by lifting tension release lever.
OPERATION LOCKING ON THE SANDER NOTE: If the sanding belt moves while sanding, you may be applying too much pressure. When this occurs, remove sander from workpiece. If belt tracking is properly adjusted, sanding belt will return to its normal and correct position on the drive roller and front roller. Use a coarser belt when heavy sanding is desired, not heavy pressure. The importance of this cannot be over-emphasized.
OPERATION TO ADJUST SANDING BELT TRACKING n When you are sure the belt will not rub against internal parts, start the sander and fine adjust the tracking knob until the belt stabilizes. When correctly adjusted, the outer edge of the belt will be even with the outer edge of the sander. Belt life will be greatly increased if a few seconds are spent adjusting the belt tracking. See Figure 10. n Connect the sander to power supply.
OPERATION To install/remove dust bag: n Unplug the sander. WARNING: To prevent the possibility of sawdust or foreign objects being thrown into your face and eyes, never attempt to use the sander without dust bag properly installed.
