Check that all three grinding heads are folded down, that
the control levers (GRINDING HEAD UP/DOWN) are in the
DOWN position and that the driver is sitting on the seat.
If you do not want to use all the grinding heads for some
reason, the machine can still grind with the remaining grind-
ing heads. This is achieved by deactivating the head that is
not going to be used for grinding in the ALARM menu under
INVERTER ON/OFF and then folding it up.
Set the required rotation speed for the grinding heads us-
ing the GRINDING SPEED knob (1), set the GRINDING
knob to position ON (2) and immediately move the left-hand
control lever carefully forwards to move the machine. Then
adjust the rotation speed and the forward movement speed
as appropriate in the prevailing grinding conditions. Continu-
ally check the power supply to the grinding motors under
GRINDING in the OPERATION menu. If any of the indica-
tors is within the red fi eld, reduce the grinding speed.

Folding up grinding head for tool replacement
When replacing tools, grinding must be interrupted. Turn
the knob to GRINDING OFF on the control panel, and turn
the STEERING knob to OFF. Move the GRINDING HEAD
POSITION control backwards to "position up" for the grind-
ing heads that are to be lifted.
When a green indicator (LOCK LEFT, LOCK CENTER,
LOCK RIGHT) can be seen under "SERVICE MENYN" in
the control panel, this indicates that the grinding head is
locked and secured, making it possible to go in underneath
and replace the tool. See the chapter on "replacement of
tools".
