Operation
Grinding
Each grinding head can be folded up and down individually.
This is achieved using the GRINDING HEAD POSITION
levers (see figure below). If the levers are moved forwards,
the grinding heads are folded down, and if they are moved
backwards the grinding heads are folded up. During both
folding up and folding down, the mechanism stops automati-
cally when the grinding head is in the relevant end position.
If the levers are retained in the forwards position when the
grinding heads are folded down, the machine automatically
adjusts the height of the lifting arms to compensate for any
unevenness in the floor. A green lamp in front of the relevant
lever indicates that this function is activated. HTC recom-
mends that this function is always used during grinding.
