Troubleshooting – Mechanical and Electrical Problems
Trouble
Machine will not
start/restart or
repeatedly trips
circuit breaker or
blows fuses.
Probable Cause
No incoming power.
Cord damaged.
Overload automatic reset has not
reset.
Band Saw frequently trips.
Building circuit breaker trips or fuse
blows.
Switch or motor failure (how to
distinguish).
Motor overheated.
Remedy
Verify machine is connected to
power source. Make sure START
button is pushed in completely, and
the STOP button is disengaged.
Replace cord.
When the band saw overloads on
the circuit breaker built into the
motor starter, it may take time for
the machine to cool down before
restart. Allow unit to adequately
cool before attempting restart. If
problem persists, check amp
setting on the motor starter.
One cause of overloading trips
which are not electrical in nature is
too heavy a cut. The solution is to
reduce feed pressure into the
blade. If too heavy a cut is not the
problem, then check the amp
setting on the overload relay. Match
the full load amps on the motor as
noted on the motor plate. If amp
setting is correct then there is
probably a loose electrical lead.
Check amp setting on motor
starter.
Verify that band saw is on a circuit
of correct size. If circuit size is
correct, there is probably a loose
electrical lead. Check amp setting
on motor starter.
If you have access to a voltmeter,
you can separate a starter failure
from a motor failure by first,
verifying incoming voltage at 220+/-
20 and second, checking the
voltage between starter and motor
at 220+/-20. If incoming voltage is
incorrect, you have a power supply
problem. If voltage between starter
and motor is incorrect, you have a
starter problem. If voltage between
starter and motor is correct, you
have a motor problem.
Clean motor of dust or debris to
allow proper air circulation. Allow
motor to cool down before
restarting.
