Preparations for dry grinding
Note!
Make sure that the floating cover can move freely within its movement margins
and that the cover rests on the floor before starting the machine.
1. Connect a dust extractor to the machine. For dust extractor models, see under the
Suction System tab in the HTC Product Catalogue.
Note!
The dust extractor's suction hose must be connected to the appropriate
socket on the machine. Adjust the dust extractor to match the grinder's
capacity.
2. Inspect the floor carefully and remove any objects sticking up, such as
reinforcement rods or bolts, and any debris that could get caught in the machine.
