Do not lift the machine off the ground while starting it. Doing so could cause
the diamonds to release from the machine, resulting in damage to the floor or
personal injury.
To start the machine:
1. Apply downward pressure on the handle to alleviate some pressure off the
diamonds; press the green start button.
2. The status on the screen will change from stopped to forward acceleration.
The load will increase as indicated by the percentage at the bottom right.
3. Once the machine starts, gently release the downward pressure and start
grinding.
4. Use the Speed Control Knob to select desired speed.
5. Once the machine reaches the desired speed, the following screen will
appear. The speed will remain constant as long as the load applied remains
below 100%. If the machine is running at speed and the load begins to
exceed 100%, the machine will reduce its speed as a protective measure to
try and alleviate the outstanding load. This happens under demanding
conditions and is normal.

The speed of the machine can be adjusted when the machine is running or
stopped. To adjust the speed, rotate the speed control knob on the handle
counterclockwise to slow it down or clockwise to speed it up.

To stop the machine, push the stop button on the handle or the STOP button on
the VFD.

To install and remove the pad driver on the bottom of the machine, you will need
a 9/16” (14 mm) socket wrench, a soft face mallet, and some medium-strength
thread locker (blue Loctite 243 or equivalent).
To remove the pad driver:
1. Slip the 9/16”(14 mm) socket wrench over the pad driver bolt and strike the
wrench with the soft face mallet in a counter-clockwise direction.
2. When installing a new pad driver or re-installing an existing one, apply a
generous amount of thread locker compound to the end of the bolt and fit it
through the hole in the pad driver. Reapply thread locking compound every
time a pad driver is removed.
3. Line up the bolt to the threaded end of the shaft and start the first couple of
threads.
4. Once the bolt is engaged, make sure that the drive shaft tongue is properly
seated within the pad driver’s slot before tightening the bolt all the way.
