PROBLEM
PBOBABLE CAUSE REMEDY SUGGESTED
Excessive noise. 1. M otor
1. Have motorchecked by qualified s^rvfce technician. R epair
service is avaiable at your nearest Sears store.
M otor fails to devel­
op full pow er.
N O TE: LO W VO L­
TAG E: (Pow er out­
put of m otor de­
creases rapidly w ith
decrease in voltage
at m otor term inals.
For exam ple, a
reduction of 10% in
voltage causes a
reduction of 19% in
m axim um pow er
output of w hich the
m otor is capable
and a reduction of
20% in voltage
causes a reduction
of 36% in m axim um
pow er output.)
1 - C ircuit overloaded w ith
lights, appliances and
other rm tors.
2. U ndersize extension cord
or extension cord too
long.
3. G eneral overloading of
pow er com pany facilities.
1. D o not use other appliances or m otors on sam e circuit
w hen using the Dust C ollection System .
2. Increase the wire sizes on extension cords, or reduce
length of extension cords. See "M otor Specifications and
Electrical R equirem ents" section.
3. R equest a pow er check from the pow er com pany.
M otor starts slow ly
or fails to com e up
to full speed.
1. Low voltage.
2. W indings burned out
or open.
3. Starting sw itch w ill not
operate. (Sw itch contacts
w orking properly.)
C apacitor is bad.
1. R equest voltage check from the power com pany.
2. H ave m otor repaired or replaced by a qualified service,
technician.
3. H ave capacitor replaced by a qualified service technician.
M otor overheats 1. M otor overloaded.
2. Im proper cooling. (Air
circulation restricted
through m otor due to
sawdust, accum ulating
inside of m otor.)
1. C lean out saw dust to provide norm al air circulation through
m otor. See "M aintenance" section.
M otor stalls
(resulting in blown
fuses or tripped
circuit breakers).
f. Voltage too low to perm it
m otor to reach operating
speed.
2. Fuses or circuit breakers
do not have sufficient
capacity.
1. R equest voltage check from the power com pany.
2. Install proper size fuses or circuit breakers.
Frequent opening of
fuses or circuit
breakers.
1. M otor overloaded.
2. Fuses or circuit breakers
dk> not have sufficient
capacity.
1 .Install proper size fuses or circxiit breakers.
NOTE; Motors used on wood-workir>g tools are particularly susceptible to the accorrajlation of saw­
dust and wood chips and shouW be btown out or "vacuumed" frequently to prevent interference with
fKjrmal motor ventilation and proper operation of the centrifugally-operated starting switch.
