safety (continued)
• Make sure that the grinder is off before plugging it in.
• Do not apply extreme force on the tungsten while grinding. This may cause your grinder to jam or cause pre-
mature grinding wheel wear.
• Never leave the grinder unattended. Turn the grinder off first and do not leave it until it comes to a complete stop.
• Keep hands away from moving parts.
• Know your grinder; learn its operation, applications, and specific limitations.
• Always unplug grinder prior to inspection.
• Read this manual thoroughly for specific adjustments and operating procedures.
Operator should know How to Use the Grinder
• Only use the grinder for its intended purpose. Do not use it for a job it was not designed for. Grinding parts
other than tungsten will severely decrease wheel and equipment life.
• Unplug the grinder when changing accessories, such as collets, wheel, or other replacement parts.
• Avoid accidental start-up. Make sure that the grinder is in the off position before plugging it in.
• Do not force the grinder. It will work most efficiently at the rate for which it was designed. Consult the “
Recommended Minimum Cutting and Grinding Time for New Electrodes” sticker on the grinder to determine
optimum rate of speed.
• Use recommended accessories. Use of improper accessories may cause risk of injury of persons or accelerated
wear on the grinder.
• Handle the tungsten and grinder correctly. Consult grinder operation procedures in this manual and handle
tungsten with pin vise whenever possible to protect hands from possible injury.
• Feed tungsten into grinding wheel against the direction of rotation of the wheel.
• Turn the wheel off if it jams. A wheel jams when it digs too deeply into the tungsten (the motor force keeps it
stuck in the tungsten).
• Never leave the grinder unattended. Turn the grinder off first and do not leave until it comes to a complete
stop.
• Never stand or lean on the grinder. Serious injury could occur if the grinder is tipped or if the cutting tool is
unintentionally contacted.
• Keep hands away from moving parts and cutting surfaces.
Operator should Be prepared for the Job:
• Wear proper apparel. Do not wear loose clothing gloves, neckties, bracelets, or other jewelry which may get
caught in moving parts of the machine.
• Wear protective hair covering to contain long hair.
• Wear safety shoes with non-slip soles.
• Wear safety glasses. Prescription glasses have only impact resistant lenses.
• Wear face mask or dust mask.
• Be alert and think clearly. Never operate power tools when tired, intoxicated, or when taking medications that
cause drowsiness.
