The moment it is switched on& a small quantity of vegetables r put in the machine starts vibrating & in another minute starts spinning out of control,it's difficult to hold it down with both hands.

There is no machine for consumers that takes out all the pulp.

THE SOLUTION TO VIBRATING. If it spins up ok and starts vibrating suddenly as you are feeling it, here's the solution: feed it very, very, slowly. that's it. i couldnt figure mine out, then realized that if i fed it slowly, it was just fine.

Just the opposite. The only way I get by the vibration is with an old worn blade which
I sharpen with a drill using a small bit. Installed a new blade, once, and the juicer took
off on me. Even the pro's have trouble with the vibration issue. If trouble persists, try
a pulp ejecting type.

A small piece of cabbage should not stop this machine. If it did stop, look for the red reset
button on the bottom of the juicer. I've been using mine for 21 years and occasionally it will
stop when run for an extended period especially if vibration is present. In each case I waited
a few minutes and pushed in the reset button.

There is no solution. These juicers do not eject the pulp and go out of balance very easily.
Don't feel bad, I've seen you tube videos where the demonstrator couldn't keep it under
control. If you are unable to master it, consider a pulp ejecting or masticating type juicer.

It's going out of balance like a washing machine with the clothes
on one side during the spin cycle. I've had mine for 20 years and
have not completely mastered the balance problem. Just try to
feed produce as slowly and as evenly as you can. If it really starts
to vibrate too badly, turn it off immediately or the blade will jump
and cut the feed chute.

Make sure the bottom of the feed chute is not damaged. If it,s chipped or scored, try filing
it down level as best you can. Then with the juicer fully assembled, unlock the set screw
on the center of the bottom and turn it clockwise until the chute contacts the blade, then
back it off a half turn and lock it down. By the way a dull worn blade will produce less
vibration. I'm assuming the lid is plastic.

DROP THE FILTERS. FRUITS AND VEGETABLES HAVE TO BE FED SLOW
AND STEADY. IF THE JUICER IS OLD THE
GAP BETWEEN BLADE AND CHUTE MAY
BE TO WIDE LETTING LARGER PIECES
THRU AND THROWING IT OUT OF
BALANCE. USING ONE FOR 19 YEARS
AND THEY ARE TRICKY.

I would say you are right. The blades are dull & or
the balance of the motor has become lose or broken free. A broken blade can also through balance off.

Replace or repair.

IT'S THE RESET BUTTON AND THEY ARE
ADJUSTABLE. REMOVE 4 SCREWS UNDER
JUICER TO REMOVE BOTTOM. YOU CAN
GET AT THE RESET BUTTON HOUSING AND
ADJUST THE SMALL SCREW EITHER WAY.
YOU WILL HAVE TO FIGURE OUT WHICH
DIRECTION. CLOCKWISE OR COUNTER.
IT YOU GET IT WRONG IT WILL CUT OUT
MORE FREQUENTLY SO JUST GO THE
OTHER WAY.
