G1052 9" Bandsaw -29-
SYMPTOM
Motor will not start.
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.
Motor stalls (resulting in
blown fuses or tripped
circuit).
Machine slows when
operating.
Blade does not run even-
ly on wheels or runs off.
Blade does not cut even-
ly
Ticking sound when the
saw is running.
Blade contacting table
insert.
Excessive vibration.
POSSIBLE CAUSE
1. Low voltage.
2. Open circuit in motor or loose
connections.
1. Short circuit in line cord or
plug.
2. Short circuit in motor or loose
connections.
3. Incorrect fuses or circuit
breakers in power line.
1. Power line overloaded with
lights, appliances, and other
