FAQS
What lubricants should I use with the
All-U-Need?
We recommend using only clean water with
the All-U-Need. If desired, you may add a water
soluble coolant to the water.
Can I reuse water for diamond
grinding?
You can, but we don’t recommend this. When you
reuse water, you risk getting contamination on
your diamond discs which increases the chances
of unwanted scratches on your work pieces. For
best results, use clean water every time you use
the All-U-Need.
How do I clean the white catch tray?
To prevent the drain tube from clogging, flush
the white catch tray after every use on the All-
U-Need by taking a small bucket of clean water
and pouring the water into the catch tray so the
leftover rock sediment gets flushed down the
drain tube. Once you see all of the sediment
gone and the white catch tray is clean, your
All-U-Need will be ready for the next use. If you
need to remove the white catch tray for further
cleaning, do so by removing the arbor with the
Allen wrench that is included with the All-U-Need
instruction manual.
What is the clear tube attached to the
arbor for?
The clear tube attached to the silver arbor helps
prevent water from getting into the motor. The
All-U-Need is designed in such a way that water
should never get into the motor if properly used,
but this is another solution in preventing this
from happening.
Can I reuse backing plates that are
backed to used, old smoothing discs,
polishing pads and diamond lap discs?
Yes. Purchasing new backing plates for new
smoothing discs, polishing pads and diamond
laps is not required, if you can properly remove
them from the backing plate. To remove diamond
smoothing discs and polishing pads from backing
plates, simply heat the surface of the diamond
smoothing disc using a heat source from a hair
dryer or heat gun. This takes approximately
2-3 minutes. Peel off the disc from the backing
plate. If there is residual glue stuck on the
backing plate, take a razor blade and scrape it
off. To remove diamond lap discs, which are the
electroplated diamond discs, use the same heat
process as above and use a screwdriver to prop
off the disc from the backing plate.
Note: If for
some reason you can’t remove all of the residual
glue from the backing plate, we recommend
purchasing a new backing plate. If the surface
on the backing plate is not fully clean or smooth,
this may cause new discs, pads or laps to not stick
properly or lay flat on the backing plate surface,
causing unwanted bumps and grooves on your
work pieces.
Do you sell electrical spare parts for
my All-U-Need? Whom do I contact if
I need a repair or replacement for my
All-U-Need?
Due to the technical nature of our machines,
we do not offer electrical spare parts for you to
install yourself such as motors, speed controllers,
rectifiers, etc. Instead, we offer a repair
service that is done in-house by our qualified
technicians. For more information about our
repair service, visit hitechdiamond.com/repairs.
