4.7 Preparations for dry grinding
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.
1. Connect a dust extractor to the machine. For available models of dust extractors, go
to HTC's website
www.htc-floorsystems.com for more information.
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.
Note!
The dust extractor can be connected to both sockets found on the protective
cover for the machine. If you only use one of the sockets, the socket not in
use should be covered. 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.
3. Attach the appropriate tool to the machine, see under Fitting grinding tools, page
22
4. Set the handle to the working position, see Figure 4-2, page 17 .
4.8 Preparations before grinding with Mist-Cooler
HTC 650 RX is equipped with the Mist Cooler system for effective cooling of the
grinding tools. The system involves dispersing a very finely divided water mist onto the
floor surface through a mouthpiece. This cools the tools and makes grinding more
effective.
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.
