Trouble Shoot the Cyclone Sample Mill
These are very short videos but they show the process.
Before we get into the testing: Mill health can be tested by simply turning the impeller by hand using your finger.
With the mill unpluged of course, remove the cover, listen as you turn the impeller, You should feel a smooth rotation, no rubbing or scraping.
You are turning the impeller which in-turn rotates the belt pulleys and the electric motor.
Remove the belt access ring so that you can see the belts and the pulleys turning as you rotate the impeller.
The belts should be tight and the 'tension adjust screw' should be adjusted so that the brass washer is loose to the touch.
If all that looks good continue with the remainder of these simple tests.
Check the Fuses
On the 220 volt version you will find two fuse holders, both fuses need to be check. We use an Ohm meter to ensure the fuses are servicable. ( see video )
Replace the blown fuses with fresh ones ( 10 amp )
Next make sure nothing is binding
If it seems as though the mill is struggling to maintain speed.
- Clean under the impeller ( see video on the main page - Main Page) Watch this video and inspect the chamber base under the impeller for rubbing. Unplug the mill and replace the impeller.
Check Current Draw
If you can measure the current draw it can be revealing.
With the mill unplugged
- remove the impeller.
- plug the mill back in.
Press the safety switch to start the motor. Use a pencil or suitable implement to press down the small black plastic extension.
(NOTE: DO NOT do this test with the impeller on.)
To test the the current draw: ensure the impeller is secure, and the cover is in placed and latched down. The 220 volt mill, with the impeller installed, should draw about 2.5 amps per leg.
Source Voltage
If you have wired a plug onto the mill cord - check to make sure the connections are proper and tight.
BE CAUTIOUS AS THESE CAN BE LETHAL VOLTAGES.
Measuring the source voltage to be 220 Volts.
The measured source voltage can be between 208v and 227v and should work just fine. (50/ 60 HZ)
If the voltage drops below 200 volts the mill will draw excesive current and may run slugesh.
( The motor is a high quality 50/60 HZ motor and should last the life of the mill. )
Check the Belts
There is really good information on the UDY Technical Library look for 'Changing the belts.' General trouble shooting guides
