To adjust the handle, pull the pin (H). Adjust the handle to a comfortable
operating position. Re-insert the pull pin.

Failure to check the pull pin is fully reinserted could result in damage to the
machine or personal injury as the handle could release unexpectedly when the
machine is being operated or tilted back.!

When the machine is first plugged in, a start-up screen (I) (Fig 1) will appear
showing the VFD model and the software version that it has been released with.
After the machine runs through its initial start-up sequence, the screen (I) will
show the VFD status and pad driver speed in revolutions per minute (RPM).
To start the machine:
1. Gently squeeze the activation lever (J) and press and release the START
button (A). If doing heavy prep/coating removal, apply a slight downward
pressure on the handle to alleviate some weight off the tooling when starting
the machine ensuring the machine does not lift off the ground.
2. Once the machine starts, gently release the downward pressure and begin
grinding.
DO NOT lift the machine off the ground while starting it. Doing so could
cause the tooling to release from the machine, resulting in damage to the floor or
personal injury.
The speed of the machine can be adjusted when it is running or when it is
stopped. To adjust the speed, rotate the speed control knob (B) (Fig 5) on the
handle clockwise to slow it down, or counterclockwise to speed it up. Always start
the machine at the lowest speed and adjust as necessary.
Once the machine reaches the desired speed, 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. The current running
speed will be displayed. This happens under demanding conditions and is
normal.
If the machine is not able to maintain the minimum speed for more than 30
seconds the machine will turn off. This is a normal protective measure. To
prevent this from reoccurring alleviate some of the load and then resume
operation.
