The device has to stand horizontally on a steady and even surface. Install the device in a place where it will not block the working area and the functionality (take the dimensions into account). Make sure that there are about 10 cm of free space on each side to guarantee air circulation (heat dissipation).

**** Do not install the unit outdoors or in places without proper ventilation. Before start-up, be sure the device reaches room temperature.

Installation/ Start-up

**** Before starting the unit, connect up the following:

Installing and Removing the Brush Spindles

The nuts must first be removed before you install the brush spindles. Use a cloth to ensure that the shaft ends are free of grease and then remount the nuts. Use compressed air to remove any dust and dirt from the brush spindles.

Then install the spindles as marked: L = left and R = right. Fix the spindles in place by tapping lightly and carefully on the tip of the taper using a hammer and a plastic block.
Do not use force as this could damage the bearings and void the warranty.

Finally, insert the power plug into the socket, making sure that the mains and the unit operate on the same voltage.

When the motor is on, the spindles must run true. If they do not, repeat the installation process.
