Replacement of the pulley units

•

First, unscrew the nut which is holding the grinding unit

•

When released, pull out the whole unit. Carefully pull out the unit with crowbars, but do not use

excessive force.

•

check the rollers. They can be removed by securing the roller from the top of the shaft and

releasing the nut underneath. Here also, you may pull lightly with the crowbars. Do not forget to
check the tension device. If necessary, replace the complete unit.

•

Pull the belt with the help of the tensioner. The strength should be so that with

=63N±7N in the

middle of the belt between the two bearings the tolerances should be 3 mm.
