3.2 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.
5. Check that the rubber insulation is stripped enough and is not causing a bad
connection. Check that all the screws are tight.
6. 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.
1. The stop switch is faulty. Replace the stop switch.
Motor tries to start but will not turn.
1. With the power disconnected from the machine, try to turn the spindle by
hand. If the spindle will not turn, check the reason for jamming.
2. Capacitor faulty. Replace the capacitor. (N/A for MLAREVO1216EVS)
3. Motor faulty. Replace the motor.
4. Power line overloaded. Correct overloaded condition.
5. 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.
Digital Read Out (DRO) is displaying an error.
1. Err1:Over-current mode
If the operating current of the motor exceeds 18 Amps for 30 seconds, the control
board goes into Over-current protection mode.
Over-current mode is to stop the motor immediately and the display shows Err1.
Release the Over-current mode steps:
a) Press the stop button to release the Over-current mode.
b) Press the Start button again and the control board restarts the motor.
2. Err2:Motor work fail mod
After pressing the start button, if the motor is not running after 25seconds, the
control board enters the Motor work fail mode
In the motor work fail mode, the control board immediately stops the motor
operation and the display shows Err2.
Release the Motor work fail mode steps:
a) Press the stop button to release the Motor work fail mode.
b) Press the Start button again and the control board restarts the motor.
3. Err3:Spindle work fail mode
After pressing the start button, if the control board detects that the spindle is not
running for 30 seconds after the motor runs normally, it will enter the Spindle
work fail mode.
In the Spindle work fail mode, the control board immediately stops the motor
operation and the display shows Err3.
Release the Spindle work fail mode steps:
a) Press the stop button to release the Spindle work fail mode.
b) Press the Start button again and the control board restarts the motor.
