The machine comes with two electroplated diamond wheels, four resin diamond
wheels, one full face diamond flat lap and one canvas polishing pad. The direct
drive motor on eliminates belts and other exterior motor parts to maintain or
replace. The unique water system and allows you to independently control the
water spray on the wheels. Always use adequate water while in use to avoid
running the wheels dry. If the wheels become covered with stone residue, increase
the water flow. We recommend wearing the included apron to keep you from
getting wet while you work.
Another advantage of our water system is that you can adjust the direction of
spray on each wheel. This allows you to use wheels of different widths. This is
achieved by locating the y-split under the hood. Adjust the two nozzles inserted
into the Y-split by twisting to the left or right.
Use rocks, glass, synthetic materials and metaL to polish and polish various
shapes and designs. The most popular use is to make cabinets.
Grinding starts with the electroplated diamond wheel on the left axle to complete
the grinding process. The grinding process shapes your cabinet and eliminates
any surface irregularities so that stones can be smooth and polished. Hold your
stone free hand or on a pigeon stick. Start with 80 # electroplated diamond wheel.
Grind the surface of the stone completely with enough water. If the stone is not
completely ground, it will be scratched. Ensuring that all scratches are removed is
the most important part of grinding debris. We recommend that you often dry your
clothes with paper towels or clean rags to expose the remaining scratches during
work. Repeat this process for 220 # electroplated diamond wheel.
The sequence of resin wheel starts from 280 # resin wheel, then continues to 600
#, 1200 #, and finally 3000 #. Thoroughly grind and smooth your stone on each
wheel and move to the next wheel to finish. After you finish the resin wheel
sequence, your cabinet will be ready for polishing. Adjust the lamp to provide
additional light while working.

1. Assemble and determine a suitable and well-lit place to place your studio. This
machine weighs about 60 pounds, needs a solid table and surface, and has a
transparent space of 3 feet wide and 2 feet deep. Place the machine on a stable
workbench (such as marble flat table, iron table, etc.). It is not recommended to
install it on a lightweight table, which will cause great vibration.
2. Open the box and remove all loose foam and accessories. Please put this
package aside if you need it later. Lift the machine directly through the bottom
plate, remove the unit from the box and place it in the predetermined position. Do
not lift the machine with the hood or indicator light. We recommend two people to
help carry out this step. As an option, you can keep the foam under the substrate
as it will help support and vibrate. Please note that there is a rectangular rubber at
the bottom of the base plate, so the machine will not sit completely flat.
3. To complete the left wheel assembly, you need to install the 80 # and 220 #
grinding wheels contained in the accessory box. Use the provided flange wrench
to remove the lap adapter on the left shaft and turn it clockwise. Remove the two
3/4 inch shims. Leave the 1-inch shim on the shaft. Slide the 220 # wheel onto the
left axle, ribbed side, facing the motor. Then slide two more 3/4 inch shims. Finally,
slide the 80 # wheel onto the left shaft with the rib side facing the motor, tighten the
lap adapter, and use the flange wrench to turn it counterclockwise. After the left
wheel is assembled, there should be two 3/4 inch intervals between 80 # and 220
# wheels, and one 1 inch interval between 220 # and 280 # wheels.
4. Place the transparent stone tray on the top of the left and right head covers.
The stone tray is used to store your stones and workpieces. Insert your hand into
the drip tray and slide the splash guard onto both sides of the drip tray. Adjust the
position of the splash-proof device according to the splashing situation.
5. Optionally, connect the side panel to the hood. They have magnetic connections
for easy installation. Install one side panel on the left engine hood and the other on
the right engine hood, farthest from the engine. Just move the black side spray

- 10 -
pipe upwards to connect and remove the side panel. These side panels help
control water splash, but without installing them, they provide easier access to
diamond rings and canvas mats.
F IN A L A S S E M B LY
6. Turn the water control knob on the left and right engine hoods to the closed
position. Screw the two side valves on the side spray pipe to the closed position.
When the black arrow on the side valve points to the left, they are in the closed
position.
7. The GFCI safety adapter plug is built into the motor power line. It is strongly
recommended to use the GFCI safety plug to prevent electric shock. Connect the
motor power cord to a power outlet. Although the motor is sealed, you must ensure
that all electrical connections are dry.
8. Connect the power cord of the lamp and the water pump to the power socket
protected by the surge. The pump has no on/off switch, so it will start to work once
you connect it to the power supply. Always unplug the water pump from the power
supply Not in use. Avoid contacting the water pump in the bucket when starting. Do
not unplug the plug or touch the power cord with wet hands.
9. Adjust the two transparent wheel splash protection devices on the engine hood
so that the wheels will not contact them. Make sure that the wheels do not come
into contact with any components Before opening the machine, the wheels must
rotate freely. You can turn on the machine now. The wheels rotate at 1800 rpm.
Typically, the motor makes a winding sound when starting and a slight buzzing
sound when closing. In some cases, the motor may produce a high-pitched sound.
This is probably caused by the space between the unit and the table surface. You
can reduce the sound by placing a cloth under the device. When the machine is
turned off, the wheels are stationary.
10. Turn the water control knob to the open position to start dripping. Don't open
them all at once, or you will waste too much water. We recommend opening one at

- 11 -
a time when you work on that wheel. Our unique water system allows you to drip
water on each wheel separately. You can adjust the water-saving knob according
to your preference. When using, ensure that there is enough water to keep the
wheel from drying. Never let the wheels dry. To use canvas pads or side spray of
diamond discs.
11. You are now ready to read the rest of this instruction manual, especially the
safety instructions, before use to avoid the risk of injury.
