1.
Excessive blade wobble
(causes oversize kerr
and unsmooth cut.)
Excessive noise
Motor' starts slowly or
fails to develop full
power_ NOTE: A low
voltage condition will
cause the power output
of the motor to decrease
rapidly_ For example, a
reduction of 10% in volt-
age causes a reduction
of 19% in maximum
power output of which
the motor is capable_
Motor' ovedleats.
Motor stalls (resulting in
blown fuses or tripped
circuit breakers.)
Frequent opening of
fuses or circuit breakers
Fence is hard to slide
2_
Motor
Circuit overloaded with lights,
appliances and other motors..
Undersize wires or circuit too long..
3_ General overloading of power
company facility. (In some sections
of the country, demand for electri-
cal power may exceed the capacity
of existing generating and distribu-
tion systems..)
4. Incorrect fuses or circuit breakers
in power line..
5o Bad/worn brushes
1. Motor' overloaded.
2_ Improper' cooling, (motor air circu-
lation restricted due to sawdust
accumulating
inside of saw).
1_ Voltage too low to permit motor to
reach operating speed
2. Fuses or circuit breakers do not
have sufficient capacity.
3_ Feed rate too fast or dull blade_
1. Motor overloaded
2_ Fuses or Circuit breakers do not
have sufficient capacity
3. Feed rate too fast or dull blade
1,. Front fence rail surface is dry_
1. Have motor ctlecked by Sears Service Center_
1. Do not use other' appliances or rectors on the
same circuits when using the saw..
2. Increase wire sizes, or reduce length of wiring
See "Motor' Specifications and Electrical
Requirements" section.
3_ Request a voltage check from the power com-
pany.
4 Install correct fuses or circuit breakers
5_ Have brushes replaced by Sears Service Center:
1, Do not cut so fast,, Feed work slower into blade_
2. Clean out sawdust to provide normal air circula-
tion through motor. See "Maintenance and Lubri-
cation" section_
1, Request voltage check from the power company_
2_ Install proper size fuses or circuit breakers_
3,, Allow motor to cool and reset saw breaker°
1,,Don't cut so fast.. Feed work slower into blade,,
2. Install proper size fuses or' circuit breakers,
3.. Allow rnotor to cool and reset saw breaker,
1,,Apply a coat of paste wax to the top, front and
rear edge of the front fence rail surfaces,.
