Maintenance and repairs

•

5.5. Every month (or 100 hours)

5.6. Repairs

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.

5.7. Spare parts

To ensure rapid delivery of spare parts, always specify the model,

the machine's serial number and the spare part number when

ordering. Information on the model and serial number can be found

on the machine's name plate.

Information on spare part numbers can be found in the machine's

spare parts list which is available to read or print out from the

accompanying digital media or HTC's website:

Check the grinding holders. Remove the tools and run

the machine in the air at the lowest speed. If the grinding

holders oscillate or wobble significantly, they are damaged.

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.
