GENERAL SAFETY RULES
WARNING: Read and understand all instructions.
Failure to follow all instructions listed below may result
in serious injury.
WARNING:The warnings, cautions, and instructions
discussed in this owner's manual cannot cover all
possible conditions or situations that could occur. It must be
understood by the operator that common sense and caution
are factors, which cannot be built into this product, but must
be supplied by the operator.
SAVE THESE INSTRUCTIONS
WORK AREA SAFETY
• Keep your work area clean and well lighted.Cluttered and
dark work areas invite accidents.
• Do not operate power tools in explosive atmospheres, such
as in the presence of flammable liquids, gases, dust or rain.
Power tools create sparks which may ignite the dust or
fumes.
• Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
• Grounded tools must be plugged into an outlet properly
installed and grounded in accordance with all codes and
ordinances. Never remove the grounding prong or modify
the plug in any way. Do not use any adapter plugs. Check
with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should electrically
malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user.
• Do not abuse the power cord. Never use the power cord to
carry the tool or pull the Plug from an outlet. Keep the
power cord away from heat, oil, sharp edges and moving
parts. Replace damaged power cords immediately. Damaged power cords increase the risk of electric shock.
• When operating a power tool outside, use an outdoor
extension cord.

replaced with a properly grounded 3-prong receptacle
installed in accordance with National Electric Code and local
codes and ordinances.
GUIDELINES FOR EXTENSION CORDS
• Use a proper extension cord. Make sure the extension cord
is in good condition. When using an extension cord, be sure
to use one heavy enough to carry the current your product
will draw. An undersized cord will cause a drop in line
voltage, resulting in loss of power and possible overheating.
• Be sure the extension cord is properly wired and in good
condition. Always replace a damaged extension cord or have
it repaired by a qualified person before using it. Protect your
extension cords from sharp objects, excessive heat and

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.
LEVELING THE TABLE ASSEMBLY
• Place a combination square on the Table so that it touches
the Abrasive Disc. If the Table is 90 degrees to the Sanding
Paper, the square should be flush on the Pad.
• If the Table is not 90 degrees, loosen the locking handle and
tilt the Table until the square is flush with the Pad.
• Tighten the Knob to secure the Table.
• Loosen the Angle Pointer Screw and adjust it so that it points
to 90 degrees.
