5.4 Daily
• Wash the machine if it is used for wet grinding.
• Check for wear to the grinding tools – abnormal or uneven wear may indicate a
damaged grinding holder.
• Check the tool holder and grinding holder to ensure that no damage or cracks
have arisen. Replace the parts if there is any damage.
• Remove any residues of building material from the radio control unit.
5.5 Every week
• Wash the machine.
• Check the grinding holders. Remove the tools and run the machine in mid air at
the slowest speed. If the grinding holders oscillate or wobble significantly, they
are damaged.
• Check that the upper belt is whole, by turning the large disc in one direction or
the other. If there is resistance the belt is whole, if the disc rotates freely the belt
is broken.
Tip!
Recondition all the grinding holders at the same time.
5.6 Every month (or after 100 hours)
• Tighten anything that may have vibrated loose.
• Check that the grinding cover is whole and undamaged.
• Check the upper belt and replace if necessary.
• Check the seals on the shafts on which the upper belt runs and replace if
necessary.
• Scrape and vacuum-clean the parts shielded by the grinding cover.
• Test run and listen for any dissonance from the bearings.
• Clean or, if necessary, replace the filter to the electrical cabinet.
