15.1 Coolant unit
The coolant pump and the coolant tank are integrated into the base of the machine. Only
emulsions based on water may be used. The coolant system may not be operated with
flammable liquids under any circumstances. The tank must be pulled out of the base for
the purpose of checking the level. The maximum filling quantity amounts to approx. 7
liters. The coolant pump is electrically connected in the way that it can only be started
together with the grinding spindle.
A splash guard which is located beneath the pan can be attached to the edge of the pan
and offers the operator protection during wet grinding.

A flexible plastic hose serves as the supply line for the cooling liquid. A ball-type spigot
serves to regulate the coolant flow and to shutt off the line. There are drain holes in the
machine pan which are connected to the coolant tank via a return line.
