Operation

4.1

General

The following section describes how to change tools and how to operate the grinding
machine. This section does not deal with the technical aspects of grinding, such as
selection of grinding tools, etc.

For choice of tool, go to HTC's website

www.htc-floorsystems.com

for more

information.

Warning!

The machine may only be used or repaired by personnel who have received the
appropriate theoretical and practical training and who have read this manual.

Warning!

Never use the machine in an environment where there is a risk of explosion or
fire. Familiarise yourself with and follow the relevant fire safety regulations
when using the machine.

Warning!

Make sure there are no loose objects in the work area. If loose objects get under
the grinding head, these may be flung out and cause personal injury.

Warning!

Use protective equipment as shown on the labelling in the machine.

Warning!

Only start the machine with the grinding head lowered.

Warning!

The machine must only be used and moved on level surfaces. There is a risk of
crush injuries if the machine starts to roll.

Warning!

The operator must never leave the machine unattended.

Warning!

The lifting handles on the motor are intended for lifting the grinding head,
when it is separated from the chassis, and then only for short, low lifts, e.g. into
the boot of a car. The lifting handles are not to be used for lifting the complete
machine.
