WARNING: For your own safety, read all of the instructions
and precautions before operating tool.
CAUTION: Always follow proper operating procedures as
defined in this manual even if you are familiar with use of this
or similar tools. Remember that being careless for even a
fraction of a second can result in severe personal injury.
BE PREPARED FOR JOB
• Wear proper apparel. Do not wear loose clothing, gloves,
neckties, rings, bracelets or other jewelry which may get
caught in moving parts of machine.
• Wear protective hair covering to contain long hair.
• Wear safety shoes with non-slip soles.
• Wear safety glasses complying with United States ANSI
Z87.1. Everyday glasses have only impact resistant lenses.
They are NOT safety glasses.
• Wear face mask or dust mask if operation is dusty.
• Be alert and think clearly. Never operate power tools when
tired, intoxicated or when taking medications that cause
drowsiness.
PREPARE WORK AREA FOR JOB
, Keep work area clean. Cluttered work areas invite accidents.
, Do not use power tools in dangerous environments. Do not
use power tools in damp or wet locations. Do not expose
power tools to rain.
, Work area should be properly lighted.
• Proper electrical receptacle should be available for tool.
Three prong plug should be plugged directly into properly
grounded, three-prong receptacle.
• Extension cords should have a grounding prong and the three
wires of the extension cord should be of the correct gauge.
• Keep visitors at a safe distance from work area.
• Keep children out of workplace. Make workshop childproof.
Use padlocks, master switches or remove switch keys to
prevent any unintentional use of power tools.
TOOL SHOULD BE MAINTAINED
• Always unplug tool prior to inspection.
• Consult manual for specific maintaining and adjusting
procedures.
• Keep tool lubricated and clean for safest operation.
• Remove adjusting tools. Form habit of checking to see that
adjusting tools are removed before switching machine on.
• Keep all parts in working order. Check to determine that the
guard or other parts will operate properly and perform their
intended function.
• Check for damaged parts. Check for alignment of moving
parts, binding, breakage, mounting and any other condition
that may affect a tool's operation.
• A guard or other part that is damaged should be properly
repaired or replaced. Do not perform makeshift repairs.
(Use parts list provided to order replacement parts.)
KNOW HOW TO USE TOOL
• Use right tool for job. Do not force tool or attachment to do
a job for which it was not designed.
• Disconnect tool when changing belt or abrasive disc.
• Avoid accidental start-up. Make sure that the tool is in the
"OFF" position before plugging in.
• Do not force tool. It will work most efficiently at the rate for
which it was designed.
• Keep hands away from moving parts and sanding surfaces.
• Never leave tool running unattended. Turn the power off
and do not leave tool until it comes to a complete stop.
• Do not overreach. Keep proper footing and balance.
• Never stand on tool. Serious injury could occur if tool is
tipped or if belt or disc are unintentionally contacted.
• Know your tool. Learn the tool's operation, application and
specific limitations.
• Use recommended accessories (refer to page 11). Use of
improper accessories may cause risk of injury to persons.
• Handle the workpiece correctly. Protect hands from possi-
ble injury.
• Turn machine off if it jams. Belt jams when it digs too
deeply into workpiece. (Motor force keeps it stuck in the
work.)
• Support workpiece with miter gauge, belt platen or work
table.
• Maintain 1/16"maximum clearance between table and sand-
ing belt or disc.
CAUTION: Think safety? Safety is a combination of operator
