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 available models of dust extractors, go
to HTC's website
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.
3.
Attach the appropriate tool to the machine, see under Fitting grinding tools, page
15
4.
Set the handle to the working position, see Figure 4-1, page 13.

Separating and assembling the chassis and
grinding head
The machine can be split into two parts; the chassis and the grinding head. This can be
useful, for example when there is a need to pack the machine better for transport or
during maintenance and repair of one of the machine's components.
•
Hold the chassis securely, when the locking bolts and the quick release are
loosened, to prevent the chassis from falling to the ground and possibly causing
material damage or personal injury.
Tip!
Ask someone to hold the chassis while you loosen the locking bolts and the
quick release.
4.6.1
Remove the grinding head from the chassis
1.
Undo the quick release coupling for the motor cable, see Figure 3-1, page 9.
2.
Remove the suction hose from the grinding cover or from the vacuum connection,
see Figure 3-1,
3.
Remove the safety pins from the quick release, see Figure 3-2, page 10.
4.
Place the red locking hooks in each quick release in the upright position.
