I've just completed putting my 3612 together after buying it several months ago. I was highly imnpressed with the apparent quality until I started it up. I am faced with a problem that I have never seen discussed here on the forum. I wired the motor for 220 per the instructions. Every third or fourth time or so, when the switch is turned on the motor makes a split second "clunking" start up noise and jumps a little bit. When the saw blade is in the full up position this jump is just annoying on start up but when the saw blade is lowered to say quarter inch or so above the table the belt jumps off the motor pulley. Obviously this is due to the fact that there is less tension on the belt when the blade is lowered. Other times the motor starts right up without so much as a hiccup and is just a smooth and steady as can be.I have checked for belt alignment, checked the motor bolts for tightness, checked the spring that holds tension on the motor and checked for binding, all to no avail. I called Ridgid tech support and they were stumped too, advising me to take it to the service center. That may be my last resort. Since I have never seen such a problem posted on this board I figure I must be doing something wrong and can't see the forest for the trees. I need someone to pull my chestnuts out of the fire and tell me what it is I'm doing wrong. Thanks
