Warning!
Do not leave any tool keys inserted.
Before starting work, inspect the
cutter to ensure that all spanners
and wrenches have been removed.
Only use type-specific sanding belts with a width that
matches the sanding arm. When inserting the new
sanding belt, pay attention to the running direction
marked with an arrow on the inside of the belt. Incorrect
insertion results in premature wear.
