Harbor Freight DC Question

[Pat O'malley]

I just assembled my DC and powered it up. I have two questions 1.There seems to be a good amount of airflow coming from the bottom of the black motor, is this normal? 2.When powering off as the motor spins down it makes a slight clicking noise till it stops, is this normal? Thanks for the help…. Pat.

I believe the motor is fan cooled, which explains the airflow that you are feeling there. As for the clicking, I had the same sound... thought it was weird, but everything worked OK, so I forgot about it. Now it doesn't do it anymore. Maybe something is "breaking in"?? :confused:

The clicking is your centrifugal switch returning to the "stationary" position ... it's normal. The centrifugal switch is there to disconnect the start capacitor once the motor's up to speed.
