Maintenance

Regular maintenance is a prerequisite for machine safety. Replace damaged and
worn components in good time.
Check the machine and drill steel for wear and damage at regular intervals. Do not
use a very worn or damaged drill steel.
When cleaning mechanical parts with a solvent, make sure that you comply with
