TROUBLESHOOTING
My machine is vibrating...
The motor that is installed in the All-U-Need
is variable speed, meaning you can adjust the
speed in-between the range of 800 rpm - 3,400
rpm. When the All-U-Need is run at slower
speeds, you may experience a vibration. We
recommend running the All-U-Need at higher
speeds to prevent this vibration. If you are still
experiencing a vibration after running the All-
U-Need at high rpms, check to see if your discs
are properly centered. If the diamond lap disc,
diamond smoothing discs or polishing pads are
not accurately centered with the 1/2" arbor hole
in the backing plate, this will cause a vibration.
My motor is beginning to rust, why is
this?
The only possible way the motor can rust is
if there is water getting into the motor. Water
should never get into the motor with the correct
water set up so if you are seeing rust, make sure
your water set up doesn’t allow water to drip into
the motor.
What should I do if the drain tube
keeps clogging with sediment?
If the drain tube keeps clogging with leftover rock
sediment, simply flush out the sediment with lots
of clean water until the sediment gets flushed
down the drain tube. If a large piece of sediment
is clogged and stuck in the drain tube, use an air
spray gun to blow it out.
My All-U-Need is making a loud,
squeaking noise. Why is this?
If your All-U-Need is making a loud, squeaking
noise, it can be one of the following scenarios:
1) The inside of the silver arbor hasn’t been oiled
in a while. Make sure you are oiling the inside of
the arbor according to the oiling instructions on
page 10.
2) The white catch tray is raised or tilted, thus
hitting the motor shaft or arbor and causing
them to rub against each other. Make sure your
All-U-Need sits on a flat, level surface.
3) The clear tube on the arbor is rubbing against
the white catch tray. Simply push this clear tube
upward, until it can’t go any higher and is no
longer making contact with the white catch tray.
4) The arbor isn’t properly tightened onto the
motor shaft. Make sure the arbor is secured using
the included Allen wrench.
I can’t remove the arbor from the
motor shaft.
If you can’t remove the arbor from the motor
shaft using the Allen wrench, it is most likely
because the arbor and motor shaft seized
together. This is a result from not oiling the inside
of the arbor according to the oiling instructions
on page 10. If it impossible to remove, please
contact Hi-Tech Diamond at 1 (630) 596-9909 and
one of our specialized technicians will help you
over the phone for correct removal.
