Operation
The workpiece support and the stop can be adjusted to a desired angle. The workpiece sup-
port and the stop are equipped with an angle scale.
If the drive is overloaded, the motor-protective circuit-breaker may trip. To reset the motor pro-
tection switch, press the button on the side of the unit.
With the aid of an angular stop, the workpiece support can again be aligned exactly at right
angles to the grinding disc.
ATTENTION!
Use a new sanding disc if it is worn out. Continued use of a worn sanding disc may
damage the Velcro underneath.

. The grain size indicates whether an abra-
sive paper is coarse, medium, fine or very fine. Grain 100-180, for example, is a fine grain. The
numbers (40, 60, 80, 120) indicate the number of meshes per 25.4 mm length of one sieve side
of a vibrating sieve. The grain mixture of the abrasives is separated by vibrating screens
according to grain size. The higher the grain number, the finer the abrasive paper.
