Rotate the handles to the left to put the cutter above the workpiece.
In the vertical position, install the cooling system and fill it with coolant. Do not
use only water as the coolant. But you can mix water and drilling oil. Then, make
sure that the cooling system works correctly. To do this, lightly loosen the bottle cap
and use the lever to open the valve. Then, rotate the handles to the left to apply a
light pressure on the pilot pin. The coolant should fill the system and start flowing
from the cutter.
The cooling system works by gravity. Thus, in the inverted or horizontal position,
use coolants under pressure or in the form of spray or paste.
