Adjusting counterweight on Loricraft RCM

I recently bought a second hand Loricraft PRC3 record cleaning machine, but it seems the previous owner has not set it up correctly since sometimes a little knot of thread is built up under the nozzle while cleaning a record. The suction power however seems strong and sufficient, so I think there is too much downforce on the arm/nozzle.

Does anyone know how to adjust the counterweight? There is a tiny hole in the weight, but I don't see a screw inside. Do I need a set of precision screwdrivers or a different tool?

Also, I'd like to check if there is vaseline on the magnet. I cannot find a manual online on how to remove the arm. Any tips?

Many Thanks,

Didier.

Thanks for the additonal info and congrats Pradeep.

I lowered the counterweight and it seems the issue with the curling of thread under the nozzle is almost gone. It happened once during cleaning of appr 15 records.

Maybe another cause that contributed to my problem was that the thread became too wet because I was using too much fluid (I literally flooded the record) and/or I did not wait long enough to have a part of the fluid evaporated. I am now using less liquid, but make sure that it is still wet all over, then wait about 1 minute and dry the record from the label outwards. ANd leave the pump on between the cleaning steps.

I did some test recordings before and after the cleaning and the result is really amazing. Less pops and crackle and much more detail (dynamics) in the music. What a great machine!
