• Remove the bolts.

• Inspect for dust build up here. If the planetary seal is
working effectively, there should be a very minimal
amount of dust observed under the cover of the
machine. If there is a build-up of 5-6mm (1/4 inch),
then it is more than likely it is time to remove the
machine cover and check the condition of the
planetary seal.
• Remove the bolts.
NOTICE! Prior to removing belt tensioner cover plate,
ensure cover plate and area surrounding cover plate are
totally clean. Avoid debris from entering into inside of

Drive system for grinding discs

Since the grinding discs are driven by the large motor via
an inner belt that is protected in the machine,
maintenance of the drive system is not necessary until it
is time for a major service (belt and bearing replacement).
This service should normally be carried out after 12-36
months of use.
Note that certain surfaces are more demanding than
others. In turn, this will impact on the operating time
before an internal service is needed. Take the equipment
to an authorized service shop.
