Hammer C3-31 Saw Starting

Philip Krisanski All Messages By This Member #136585 开云体育 Hi Everyone ? I have a C3-31 and in recent times when I push the start button the saw blade won’t turn.? I generally grab my push stick or a scrap piece of wood and give the blade a flick and away it goes. The jointer /thicknesser starts fine. This problem only occurs occasionally . ? Any tips appreciated. Thank you Regards Phil

Felder uses one set of start and run capacitors so I would assume so does Hammer. You can check the schematic to confirm. J/P is a harder load and if start cap was going bad it should perform worse on J/P than the saw unless you have a heavy dado installed on the saw. Assuming single set of caps, I would look for a compromised connection between saw motor and start capacitor.

Caesar Simon All Messages By This Member #136587 I’ve had this problem with my C3-31. These guys (especially Imran) got me up and running again. Before ordering new capacitors, I’d try pulling that module out of the front of the saw and spray a little contact cleaner on any contacts or connections you see. Try to get some into the back of the start switch as well. Don’t overdo it as it will collect dust. CRC or I used Deoxit.? ?

There are two momentary contacts in the push button, one for the run contactor, one for the start contactor. A bit of contact cleaner with power off may help, as will making sure you press the button completely and squarely? Regards, Rod
Philip Krisanski All Messages By This Member #136592 开云体育 Thanks Rod, I will open up the switch box and get some contact cleaner in there as a first attempt. However I don’t have the problem when the switch is turned to the planer function but I am thinking the start up of the planer may be a little sluggish. So might be the start capacitor if the saw has a greater draw than the planer as Imran was suggesting. Cleaning is the easy first option and I will go from there. Thanks for your feedback.

Philip Krisanski All Messages By This Member #136593 开云体育 Thanks Imran for your feedback. Yes it is single phase. I am thinking the J/P start up may be a little sluggish. And yes there are 2 capacitors common to the 3 motors. In the first instance I think I will clean around the switch box and contactors and check connections and go from there.?
