Is there a way to reduce the turn-on bang when it starts? It seems like
sometimes when it starts there is no bang, and other times its quite
startling. I cant figure out why. I'm running it 240V. It seems like a lot
of the action may be originating from the belt guard. Anyone find a way to
dampen this "problem"?
It's normal and its due to the new belts as per Jet tech support. You could
replace them with link belts if you want the expensive option or just wait
until the belts equalize. Took mine about 6 months (intermittent use) and
now it's fine.
Oddly many cabinet saws have this happen also. I think it starts with the
220-240 volt setup. Usually with this voltage and the absence of voltage
drop at start up these motors tend to start up "instantly". Basically there
is no measurable time spent coming up to speed. Correct? The belts don't
handle this well with out the bang you hear. From what I have read, link
belts calm this problem on cabinet saws. As a side note with another
similar situation, mid 80's GM cars with diesel engines that used serpentine
belts had the same problem. The engines fired up so quickly and with so
much torque the belt would go "bang" also.
Nor does my cabinet saw do it all the time either. Seems to have a lot to
do with line voltage in general according to Jet. When I first witnessed
this 3 years ago Jet indicated that it was belt slap due to the quick
starting of the motor. The first step was to insure that all 3 belts were
properly tensioned followed by a different start capacitor provided by Jet
to slow the start up. Ultimately Jet replaced the motor all together and
this helped greatly although depending on the time of day and temperature
the bang at start up does show up now and then. Jet indicated that the
motor starts up quickly on 220 volt compared to 110 volt if the line voltage
