Keep manufacturer specified recommendations for adding the anticorrosive agents, the
antifreeze or other agents! For mixture of two different mixes can produce toxic and
aggressive mixes, which can peril your health or damage cooling system of the
machine
Note: If the machine is equipped with Microniser (see. Special accessory ), fill the tank
of the Microniser by specified cooling liquid. Microniser is ready for the operation
The quality of the cooling agent will deteriorate due to:
•
use of contaminated water
•
impurity
•
outside oil contamination (hydraulics, gears)
•
high operating temperatures
•
lack of air circulation
•
wrong concentration
If the solution is too weak:
•
corrosion protection is diminisched
•
ubrication decreases
•
microbial attack is more likely
If the solution is too strong:
•
the cooling ability is decreased
•
foam behaviour increases
•
emulsions stability deteriorates
•
sticky residue develops
4.5.3. 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.
4.6. Greases and oils
4.6.1. 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!
