Maintenance and repairs

•

Tip!

Recondition all the grinding holders at the same time.

5.5. Every month (or 100 hours)

•

Any repairs that may be required must be carried out by a HTC

Service Centre, which has trained service personnel and uses

HTC original parts and accessories. Contact your retailer if your

machine requires servicing. For contact information, see Contact

Information at the start of the manual.

Check that the upper belt is undamaged. Try to turn the

large disc in one direction. It should be quite stiff. If it turns

freely, the belt has come off.

Tighten anything that may have vibrated loose.

Remove the grinding cover and check that it is undamaged.

Check the upper belt. Replace, if necessary.

Check the seals on the shafts that the upper belt runs on.

Replace, if necessary.

Scrape and vacuum-clean the parts shielded by the grinding

cover.

Test run and listen for any dissonance from the bearings.
