TROUBLE SHOOTING
WARNING: FOR SAFETY, TURN SWITCH "OFF"
AND ALWAYS REMOVE PLUG FROM POWER
SOURCE OUTLET BEFORE TROUBLE SHOOTING.
Trouble
Motor will not start
m
Motor will not start,
fuses or circuit
breakers "blow"
Motor fails to develop
full power (power output
of motor decreases
rapidly with decrease
in voltage at motor
terminals)
Motor overheats
Motors stalls (resulting
in blown fuses or tripped
circuit breakers)
Frequent opening of
fuses or circuit
breakers
Machine slows
down while operating
Abrasive belt runs
off top wheel
Probable Cause
,,,,,,,,
1 Low voltage
2 Open circuit in motor
or loose connectionSr
1 Short circuit in line,
cord or plug
2 Short circuit in motor
or loose connections
3 Incorrect fuses or circuit
breakers in powerline
1 Power line overloaded
with lights, appliances and
other motors
2 Undersize wires or
circuits too long
3 General overloading of
power company's facilities
1. Motor overloaded
2 Air circulation through
the motor restricted.
1 Short' circuit in motor or
loose connections
2 Low voltage
3 Incorrect fuses or circuit
breakers in power line
4 Motor overloaded
1 Motor overloaded
2 Incorrect fuses or circuit
breakers
1. "V"-Belt to loose
2 Applying too much
pressure to workpiece
1. Not tracking properly.
Any attempt to repair the motor may create a hazard
unless repair isdone by qualified service technician
Repair service is available at your nearest Sears
Store,
Remedy
1 Check power line for proper voltage,
2 Inspect all lead terminations on motor for
loose or open connection
1 Inspect line cord or plug for damaged
insulation and shorted wires.
2. Inspect all lead terminations on motor for
loose or shorted termials or worn insulation
on wires
3. Install correct fuses or circuit breakers
1. Reduce the load on the power line.
2 Increase wire sizes, or reduce length of wiring
3 Request a voltage check from the power
company
1 Reduce load on motor
2 Clean out motor to provide normal air
circulation through motor
1 Inspect terminals in motor for loose or shorted
terminals or worn insulation on lead wires
2 Correct the tow line voltage conditions
3 Install correct fuses or circuit breakers
4 Reduce load on motor
I1 Reduce motor load
2, Install correct fuses or circuit breakers
,, i
1. Adjust belt tension by pushing motor toward
back until all slack is removed from belt
2 Ease up on pressure
