tech problem: PC7424

[FC in TO]

Hi all,



I got a PC 7424 from Coastal Tools as well as the velcro and I am having some problem using it. :(



I am sure the pad and backing are properly secured to the machine and followed the instruction and usage from tech article and David`s video.



But for some reason the pad is not rotaing (as it should)? When I placed the pad in contact of the (testing) surface and turned on the machine, all it did was vibrating :confused: Even if I didn`t put any pressure and just let the polisher work on its own weight the pad still won`t turn.



In some search to the machine itself I realized there are 2 counterweights available. I`ve got a 6" counterweight on its way as my 7424 came with the 5" weight when purcahsed.



Could the wrong counter weight be the problem? Or am I missing anything else?

There`s no problem with your machine. Apparently, the rotating is just a side-effect, and the main action is all orbital shaped vibrating. Put a piece of tape or something on the edge to see if it moves, and turn it up to a higher speed. It should start spinning then, although still not too fast.



Don`t lift it off at high speed though, some people have said it starts spinning dangerously fast with no load.

LOL, weird, isn`t it? It`s working right. Generally the harder you press the less actual pad rotation you get, so I typically lift it nearly free of the surface every few seconds to insure that whatever product you are using gets evenly distributed onto the pad.

Here`s a test to see if your PC is spinning correctly...



Soak a foam pad with water and attach it to the velcro backing plate. Set the dial to 6 and turn it on! If you just managed to soak everything in a 10-ft radius, it`s working properly. :D

Thanks guys. I feel enlightened :( Gee... am I the only one who doesn`t know it`s supposed to do that. Or maybe I fantacized too much about my 7424 (being orbital action w/ self-rotating pad)



Thanks for the clearification. I tried the tape thingy and it worked like 4DSC described. With that being said, I am getting fair bit of vibration from the whole machine; it`s nto too crazy but enough to make my hands numb after few min of continuous usage.

What speed are you using?



I found that when I used it @ speed 5 or 6 my fingers got numb after 10 minutes. Now I work it in @ speed 2, and I up it to speed 4 when the polish starts to dry. I never go above 4 anymore. I still get excellent results this way!
