Troubleshooting
Lathe will not start.
1. Check that the start switch is in the correct
position.
2. Check that the electrical power cord is plugged
into the power outlet.
3. Check that the electrical supply is on (reset the
breaker).
4. With the power disconnected from the machine,
check that the wiring to the plug is correct. Check
that the rubber insulation is stripped enough and
is not causing a bad connection. Check that all
the screws are tight.
5. Emergency stop button engaged. Reset
emergency stop button. Twist and it will pop out.
The machine will not stop.
This is a very rare occurrence as the machine is
designed to be fail-safe. If it should occur and you
cannot fix the fault, seek professional assistance.
The machine must be disconnected from the power
and never run until the fault has been rectified. The
only cause of this is a faulty stop switch.
Motor tries to start but will not turn.
1. With the power disconnected from the machine,

not turn, check the reason for jamming.
2. Motor faulty. Replace the motor.
3. Power line overloaded. Correct overloaded
condition.
4. Low voltage. Correct low voltage condition.

Motor overheats.
The motor is designed to run hot, but should it
overheat it has an internal thermal overload protector
that will shut it down until the motor has cooled, and
then it will reset automatically. If the motor
overheats, wait until it has cooled and restart. If the
motor shuts down consistently check for the reason.
Typical reasons are dull cutting tools, the motor
cooling fan being clogged or faulty, the motor cooling
fins are clogged, overfeeding the job, and excessive
ambient temperature.
Squeaking noise.
1. Check that the motor cooling fan is not
contacting the fan cover.
2. Check the bearings.
3. Check the drive belt is tensioned correctly.
Spindle slows down during a cut.
1. Dull cutting tools. Replace the tool or have it re-
sharpened.
2. Feeding the wood too fast. Slow down the feed
rate.
3. Oil or dirt on the drive belt. Clean or replace the
drive belt.
4. Drive belt loose. Re-tension drive belt.
Machine vibrates.
1. Machine not level on the floor. Re-level the
machine ensuring that it has no movement.
2. Damaged drive belt. Replace the belt.
3. Job is not balanced. Change to slower speed
and/ or balance the job.
4. Damaged pulley. Replace the pulley.
5. Worn spindle bearing. Replace the bearing.
