MOTOR T ROUBLE -
SHOOTING
CHART
NOTE:
Motors
used on wood-working
tools are particularly
susceptible
to the accumulation
of sawdust
and wood
chips
and should
be blown
out
or
"vacuumed"
frequently
to
prevent
interference
with
normal
motor
ventilation.
TROUBLE
PROBABLE
CAUSE
SUGGESTED
REMEDY
Motor
will not run.
Motor will not run and
fuses "'BLOW".
Motor
fails to develop
full power.
(Power
output
of motor
decreases
rapidly
with
decrease
in voltage
at
motor
terminals.
For
example:
a reduction
of
10% in voltage
causes a
reduction
of 19% in
maximum
power
output
of which
the motor
is
capable,
while
a reduction
of 20% in voltage
causes
a reduction
of 36% in
maximum
power
output.)
Motor
overheats,
Motor
starts slowly
or
fails to come up to full
speed.
Motor
stalls (resulting
in
blown
fuses or tripped
circuit
breakers).
Frequent
opening of
fuses or circuit
breakers.
1. Low voltage.
1. Short circuit
in line,
cord or plug.
2. Incorrect
fuse in power
line.
2,
3.
Power line overloaded
with
lights,
appliances
and other
motors.
Undersize
wires
or circuit
too long.
General
overloading
of
power
company's
facilities.
(In many
sections
of the
country,
demand
for
electrical
power
exceeds
the capacity
of existing
generating
and distribution
systems.)
1. Excessive
feed rate when
crosscutting
or ripping.
2. Improper
cooling.
(Air
circulation
restricted
through
motor
due to
sawdust,
etc.)
3. Saw blade has "heel".
1. Low Voltage
-- will
not trip
starting
switch.
2. Blade teeth
wedged
into
table.
1. Voltage
too low to permit
motor
to reach operating
speed.
2. Fuse or circuit
breaker
do not have sufficient
capacity.
1. Motor
overloaded.
2. Fuse does not have
sufficient
capacity.
1. Check power
line for proper
voltage.
1. Inspect
line, cord
and plug for damaged
insulation
and shorted
wires.
2. Install
15 amp Time
Delay
Fuse.
I. Reduce
the line load.
2. Increase wire sizes, or reduce
length
of wiring.
3. Request
a voltage
check
from
the power
company.
1. Slow down
rate of feed.
2. Clean out sawdust
to provide
normal
air
circulation
through
motor.
3. Refer to Alignment
Procedure
Section
of
manual
Step Five.
1. Correct
low voltage
condition.
2. Free blade from
table.
1. Correct
the low
line voltage
condition.
2. Replace fuse with
15 amp
Time
Delay
Fuse.
1. Reduce
motor
load.
2. Replace fuse with
15 amp
Time
Delay
Fuse.
