Troubleshooting the DT65 Dovetailer

Trouble

Machine will not start/restart or repeatedly trips circuit breakers or blows fuses.

Probable Cause

Machine not plugged in.

Verify machine is connected to power

 

 

Fuse blown, or circuit

If the dovetailer overloads on the circuit breaker

starter inside the electrical box.

 

 

 

Check the amp setting on the overload relay.

Dovetailer frequently trips.

Match the full load amps on the motor as noted on

the motor plate. If amp setting is correct then there

 

is probably a loose electrical lead or a failed

 

component. See below.

If you have access to a voltmeter, you can

 

separate a starter failure from a motor failure by

 

first, verifying incoming voltage at 220+/-20 and

Motor starter failure.

second, checking the voltage between starter and

motor at 220+/-20. If incoming voltage is incorrect,

 

you have a power supply problem. If voltage

 

between starter and motor is incorrect, you have a

 

starter problem. If voltage between starter and

 

motor is correct, you have a motor problem.

 

 

 

If electric motor is suspect, you have two options:

Motor failure.

Have a qualified electrician test the motor for

function or remove the motor and take it a qualified

 

 

electric motor repair shop and have it tested.

 

 

 

Check to make certain all electrical connections

the motor connections should be checked as the

 

highest probability for error. If problems persist,

 

double check the factory wiring.

 

 

 

If the on/off switch is suspect, you have two

options: Have a qualified electrician test the switch

establish if that was the problem on changeout.
