Chips disposal

Chips resulting from cutting operations must be disposed of in accordance with the
relevant regulations.
•
Let the chips drip excess fluid!
•
Fill a watertight container with the chips! Be careful that the container does not
leak, because even after a long dripping time, they still contain coolant residue.
•
Place the container into the care of a disposal company equipped for the disposal of
chips contaminated with cooling liquid. In case the machine is equipped with micro-
spray installation, the chips must also be handed over to a disposal company.

Greases and oils

4.5.1.

Gearbox oils

In gearboxes, oil is used for the whole lifetime of the gearbox. We recommend
replacing of the filling oil in case of repair.
Use oils with specification DIN 51517 in the gearboxes. Select the viscosity grade ISO
VG according to the original oil fill.
Attention:
When replacing, use oils recommended by BOMAR or oils, which
has comparable parameters from the other manufacturers.
Do not forget, that mineral and synthetic oils must not be
mixed!
