_YMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
vlotor will not start !. 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. Shor_circuit in line cord or plug_otor will not start; fuses blown or circuit

in power line
_otor falls to develop full power (power 1. Power line ovedoaded with lights, 1. Reduce the load on the power iine
)utput of motor decreases rapidly with app]icances and other motors
Jecrease in voltage at motor terminals) 2. Undersize wires or circuits too long 2. Increase wire sizes or reduce length
of wiring
3. General overloading of power 3. Request a voltage check from the
company's facilities power company
vlotor overheats Motor overloaded Reduce load on motor
_otor stalls (resulting in blown fuses or 1, Short circuit in motor or loose
ripped circuit breakers connections
2. Low voltage
3. Incorrect fuses or circuit breakers
in power line
4. Motor overloaded
Inspect line cord or plug for damaged
insulation and shorted wires
Inspect al! lead connections on motor
for loose or shorted terrninals or
worn insulation on wires
Install correct fuses or circuit breakers
1. Inspect connections in motor for
loose or shorted terminals or
worn insulation on lead wires
2. Oorrect the tow line voltage conditions
3. Install correct fuses or circuit breakers
4. Reduce load on motor
Vlachine slows down while operating Applying too much pressure to workpiece Ease up on pressure
Foot"chatters" during turning operation 1. Workpieee is too far out-of-round I True up the roundness of the
2. Workpiece has too much wobble
3. Operator using bad technique
4. Cutting motion is against the grain _.f
the workpiece
5. Workpiece is too long and thin -
workpiece is deflected by tc,¢_pressure
workpiece before turning operation
2. Establish new center marks on ends
to reduce wobble
3. Read instructions and take lighter cut_
to minimize chatter
4. Use cutting motion that is with
the grain
5. Install a steady rest in the middle,
behind the workpiece
Norkpiece splits or "breaks up" during Workpiece contained defects before Select or assemb]e a workpiece that is
:urning operation mounting free of defects
