Maintenance HTC 650, HTC 800 and HTC 950 RX
Daily:
• Clean the machine if it has been used for wet grinding or mist spray.
• Check wear on the tools – abnormal or uneven wear can indicate damage to the grinding
holder.
• To avoid failure, check the tool holder and grinding holder for damage or cracks. If any dam
-
age has occurred, change the parts.
Weekly:
• Clean the machine.
• Check the grinding holders. Remove the tools and run the machine off the ground on the
lowest speed. If the grinding holders oscillate or wobble considerably they are damaged.
Overhaul all grinding holders at the same time.
• Check that the upper belt is intact. Try to turn the large disk in any direction. It should be
stiff. If it turns freely then the belt has broken.
Each month (or 100 hours):
• Screw into place everything that can have vibrated loose.
• Lift off the cover and check that it is intact.
• Scrape and vacuum the parts that are enclosed by the cover. Check the upper belt. Change
as needed.
• Check the seals of the shafts the upper belt runs on. Change as needed.
• Test run and listen for any sounds from the bearings.
