GeneralElectricalCautions
This machine should be grounded in accordance with
the National Electrical Code and local codes and
ordinances. The work should be done by a qualified
electrician. The machine should be grounded to
protect the user from electrical shock.
WireSizes
Caution: For circuits that are a great distance from
the electrical service box, the wire size must be
increased in order to deliver ample voltage to the
motor. To minimize power losses and to prevent
motor overheating and burnout, the use of wire sizes
for branch circuits or electrical extension cords
according to the following table is recommended:
Conductor
length
AWG (American Wire Gauge) number
240 volt lines 120 volt lines
0-50 feet No. 14 No. 14
50-100 feet No. 14 No. 12
Over 100 feet No. 12 No. 8
SafetyRequirementsforAbrasiveSanding
Machines
Abrasive sanding can be hazardous to operators and
bystanders. Sanding sparks, chips and dust particles
thrown off by the sanding disc can cause serious
injury if contacted or inhaled. To avoid such injuries
you must comply with the following safety
requirements:
1. Always wear protective eyewear when operating
machinery. Eye wear shall be impact resistant,
safety glasses with side shields which comply
with ANSI Z87.1. Use of eye wear which does not
comply with ANSI Z87.1 specifications could
result in severe injury from the breakage of the
eye protection.
2. Wear leather safety gloves, arm guards, leather
aprons and safety shoes.
3. A dust collection system is recommended. The
operator should also wear a dust mask at all
times.
4. Additional precautions may be necessary for
sanding materials which are flammable or have
other hazardous properties. You should always
consult the manufacturer of such materials for
instructions on sanding and handling.
5. Do not force or jam the workpiece into the
sanding disc.
6. Before sanding, always allow the motor to come
up to operating speed, then check the sanding
disc for wobble, run-out, or any unbalanced
condition. If the disc is not operating accurately
and smoothly, immediately stop the motor and
make repairs before attempting any sanding
operations.
7. Abrasive discs must be stored in a controlled
environment . Relative humidity should be 35% to
50% and the temperature should be between 60°
and 80° Fahrenheit. Failure to do so could cause
premature disc failure.
8. Examine the face of the sanding disc carefully.
Excessive sanding that wears down to the
backing material can tear the disc. Never use a
disc which shows backing, nicks or cuts on the
surface or edge, or damage due to creasing or
poor handling.
9. When installing a new disc, be certain the disc is
accurately centered on the drive wheel. Failure to
do so could cause a serious unbalanced
condition.
10. Always present the workpiece to the wheel while
resting the workpiece firmly on the table. Failure
to do so could result in damage to the workpiece
or throwing of the workpiece off the wheel.
11. Safety shoes which comply with ANSI Z41.1
should be worn.
12. Personal hearing protection such as ear plugs or
ear muffs should be used to protect against the
effect of noise exposure.
