SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
V]otor will not start 1. Low voltage 1. Check power line for proper voltage
2. Open circuit in motor or loose 2. Inspect all lead connections on motor
connections for loose or open connection
1. Short circuit in line cord or plug
V]otor will not start; fuses blown or circuit
)reakers are tripped
V]otor fails to develop full power (power
3utput of motor decreases rapidly with
:lecrease in voltage at motor terminals)
V]otor overheats
V]otor stalls (resulting in blown fuses or
:ripped circuit breakers
2. Short circuit in motor or loose
connections
3. Incorrect fuses or circuit breakers
in power line
1. Power line overloaded with lights,
applicances and other motors
2. Undersize wires or circuits too long
3. General overloading of power
company's facilities
1. Inspect line cord or plug for damaged
insulation and shorted wires
2. Inspect all lead connections on motor
for loose or shorted terminals 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
Motor overloaded Reduce load on motor
1. Short circuit in motor or loose
connections
2. Low voltage
3. Incorrect fuses or circuit breakers
in power line
4. Motor overloaded
1. Inspect connections in motor for
loose or shorted terminals or
worn insulation on lead wires
2. Correct the low line voltage conditions
3. Install correct fuses or circuit breakers
4. Reduce load on motor
V]achine slows down while operating Applying too much pressure to workpiece Ease up on pressure
tool "chatters" during turning operation 1. Workpiece is too far out-of-round
Norkpiece splits or "breaks up" during
urning operation
2. Workpiece has too much wobble
3. Operator using bad technique
4. Cutting motion is against the grain of
the workpiece
5. Workpiece is too long and thin -
workpiece is deflected by tool pressure
Workpiece contained defects before
mounting
1 True up the roundness of the
workpiece before turning operation
2. Establish new center marks on ends
to reduce wobble
3. Read instructions and take lighter cuts
to minimize chatter
4. Use cutting motion that is with
the grain
5. Install a steady rest in the middle,
behind the workpiece
Select or assemble a workpiece that is
free of defects
