SAFETY PRECAUTIONS
• Whenever adjusting or replacing any parts on the tool, turn
switch OFF and remove the plug from power source.
• Recheck table handle and bolts. They must be tightened
securely.
• Make sure all guards are properly attached. All guards
should be securely fastened.
• Make sure all moving parts are free and clear of any
interference.
• Make sure all fasteners are tight and have not vibrated loose.
• With power disconnected, test operation by hand for clear-
ance and adjust if necessary.
• Always wear eye protection or face shield.
• Make sure abrasive belt always tracks properly. Correct
tracking gives optimum performance.
• After turning switch on, always allow belt and disc to come
up to full speed before sanding or grinding.
• Be sure disc turns counterclockwise. Abrasive belt must
travel downward.
• Avoid kickback by sanding in accordance with the direction-
al arrows.
• Keep your hands clear of abrasive belt, disc and all moving
parts.
• For optimum performance, do not stall motor or reduce
speed. Do not force the work into the abrasive.
• Always support workpiece with table or back stop when
sanding with belt and with table when sanding with disc.
• Never push a sharp corner of the workpiece rapidly against
the belt or disc. Abrasive backing may tear.
• Replace abrasives when they become loaded (glazed) or
frayed.
