RBI Hawk With Mind Of Its Own!

[kmmcrafts]

My Hawk 220VS has started to decide at what speed to run all on its own.. LOL... I haven't had the saw all that long and have not used it much.. all seemed fine though up until a few weeks ago I noticed that if I put the speed selector dial all the way to fast that it would run sort of erratic and not a constant speed.. no big deal I just backed it off the high slightly and all was good.. but now it is starting to do this periodically no matter where the selector is set at.. while it doesn't seem to run full speed at other select speeds.. just slightly faster than where the setting is and will sort of jump back and forth from the correct speed to a little faster speed and back and forth.. not consistently either.. I may be able to saw a complete project without doing it.. while other times it has a mind of its own.. typically if I play around with the adjustment some.. it will stop for a while.. Not sure if this might harm anything else by just running it this way? I know they had some issues with the older motors etc and they are not cheap to replace on the older machines.. 

 

I took the power switch and the speed selector box apart to see if there was anything visible going on with it and to blow out any dust etc that may have collected in there over the years.. I didn't really see anything out of the ordinary and not really any dust.. blew it out with the air hose and put it back together.. that didn't seem to fix the problem.. I am assuming it needs a new speed selector portion.. but thought I would ask here before purchasing one as maybe someone knows more than me about this issue??

 

Thanks in advance for any suggestions,

Kevin,   Consider contacting Hawk Mfg. service  group direct and explain your saw problem. Have an older Hawk model and have needed their advice on replacement parts, which they gave good advice. wc

I had a Craftsman that did the same thing,It was still under warranty so I took it back and exchanged it.The other ran fine.for a few years.

My DeWalt did this once..or maybe it was the old Dremmel I had.. anyway it was several years ago and I remember taking it apart and blowing dust out of it.. which fixed it.. and never had another issue.. Probably was my DeWalt.. as after that I made a seal out of an old latex glove that I taped over the switch.. either way.. I just figured it was dust.. but the RBI didn't seem to have any..plus I blew it out anyway.. so not real sure.. I guess I will give them a call to see what they have to say.. I wonder if they can even get the parts on this old saw..

Contact Bushton Manufacturing.  They make the new Hawks and are highly knowledgeable on the old models.  They are also the best source for parts should it came to that.

call Hawk & ask for Nicole. Explain your issue to her. Sounds like your vs switch is goin' out. I spent quite a few hours on a 220vs. Nicole will get ya fixed up.

My wife does the same thing. There is no fix for it, you just have to put up with it. So far I have had no problem with my scroll saw. An EX16!!!

i don't know if this is the same problem ,but my home made foot switch burnt out my wonderful c arm craftsman.The switch would at times shutting off go into hyper mode and made the saw run like it was on 220 volt.It did this one to many times and i lot the mother board.so to the dumpster it went that was one of my best saws.

You may be onto something with this... as the foot switch seems kind of finicky .. not sure if it's just the way I step on it or if it's going bad now that you mentioned this.. I have another foot switch on my other saw.. I think maybe I will swap them out for a test run and see if there is any difference..

 

Thank you for taking the time to suggest this to me,
