OPERATING INSTRUCTIONS
1
Carefully unpack the All-U-Need from the box
and remove all loose foam and accessories.
Set the packaging aside should you need it in the
future. Check to make sure all parts are present
on both the machine and in the accessory kit. If
you find any missing or damaged parts, call us
immediately at 1 (630) 596-9909 or email us at
sales@hitechdiamond.com.
2
Place the All-U-Need on a table or surface
that is flat in a well lit location. Make sure
the machine sits level and the white catch tray
is securely mounted on a horizontal plane on
the motor housing. If the tray is raised or tilted,
it will hit the motor sha or silver arbor and rub,
causing a squeaking sound on the arbor.
3
Install the water system by inserting the black
tube with valve into the white cup with the
hole. Position this cup on top of the spray shield.
Insert the clear drain tube into the drain hole
on the bottom right side of the white catch tray.
Position the other white cup under the drain tube.
See cover image for correct set-up. Fill the top
cup with clean water. Never re-use water. Note: To
install the optional cup holder or Pro-Flow water
cooling system, see page 11.
4
Install your discs by inserting the disc bushing
into the backing plate, then place the backing
plate onto the arbor. The disc bushing can be
inserted either way but is smaller on one side to
accommodate variations in the disc hole. If you
have diiculty centering the disc, try using the
other side of the disc bushing. The disc bushing
will slightly extend out of the backing plate. Next,
place the diamond disc on top of the backing
plate, using the disc bushing to center the
diamond disc. Make sure the disc is centered and
Fig. A
has even contact with the backing plate surface.
Secure the disc and backing plate with the ¼"-20
thread knurled black knob and washers (Fig. A).
Always use a backing plate for diamond discs or
polishing pads. To determine what disc you need
to start with, see page 8.
5
Put on safety goggles (not included) and
turn the power switch on. Adjust the water
drip tube so the water is aimed at the center of
the disc. You only need a few drops of water to
adequately lubricate the discs. Never use discs
dry and use only clean water as a lubricant. Do
not use wipers or sponges, as they may become
contaminated with larger diamond particles.
You can control the water splash by raising
or lowering the black spray shield. (Fig. B).
Important note: When run at low speeds, vibration
is normal and to be expected.
