One-component paint

The machine is lacquered with a one-component paint. Take this criterion into account when
selecting your cooling lubricant and cleaning the machine.
A one-component paint with added solvent sets when the solvent evaporates.
As soon as the paint is applied, the solvent escapes into the air. The binding agent becomes
felted and a dry film is formed. This process is reversible, i.e. the binding agent can always be
re-softened.
A two-component paint also consists of binding agent and solvent. However, the paint only
dries when a setting agent is added. This process is not reversible, i.e. the binding agent can-
not be re-softened.
The company Optimum Maschinen Germany GmbH does not assume any guarantee for sub-
sequent damages due to unsuitable cooling lubricants.

Cleaning the machine

ATTENTION!
Do not use compressed air to clean the machine.
Your new milling machine must be completely cleaned after unpacking to ensure that the mov-
ing parts and sliding surfaces cannot be damaged when the machine is operated. Prior to deliv-
ery, all blank parts and sliding surfaces in each unit are appropriately lubricated to protect
against rust in the period before commissioning. Remove all wrappings and clean all surfaces
with a degreaser to soften and remove protective greases and coatings.
Wipe all surfaces with a clean cotton cloth and lubricate the milling machine in accordance with
the maintenance section
power and putting the machine into service.

Lubrication and oil level

During the initial lubrication and greasing of your new milling machine, the oil levels are
checked and the machine lubricated after cleaning. Only when this has been done can commis-
sioning of the machine proceed.

Warming up the machine

ATTENTION!
If the milling machine and in particular the milling spindle is immediately operated at
maximum load when it is cold it may result in damages.
If the machine is cold, e.g. directly after having transported the machine, it should be warmed
up at a spindle speed of only 500 1/min for the first 30 minutes.
3.12

Electrical connection

CAUTION!
Lay the connection cable to the electrical cabinet and the cable of the coded connector
from the machine to the electrical cabinet in such a way as to prevent a trip hazard.
WARNING!
The three-phase electrical connection may only be performed by an electrician or under
the guidance and supervision of an electrician.
Please check that the type of current, voltage and protection fuse correspond to the values
specified. A protective earth ground wire connection must be available.
