Cleaning the machine
ATTENTION!
Do not use compressed air to clean the machine.
Your new surface grinding machine must be completely cleaned after unpacking in order
ensure that the moving parts and sliding surfaces cannot be damaged during operation of the
machine Before delivery, all bare parts and sliding surfaces of each unit are lubricated accord-
ingly in order to protect them against rust in the period before commissioning. Remove all wrap-
pings and clean all surfaces with a degreaser to soften and remove protective greases and
coatings.
Wipe all surfaces with a clean cotton cloth.
3.8
Top up central lubrication
The machine has a manual central lubrication system. It is located on the left side of the
machine. It supplies all moving machine parts with lubricant, except the guides of the table and
slide.
Daily before starting work, the machine must be lubricated by operating the pump lever.
Suitable slideway oil is ISO VG 32 or ISO VG 68.
3.9
Coolant circuit
ATTENTION!
The surface grinding machine was painted with a one-component lacquer. Take this criterion
into account when selecting your cooling lubricant.
Optimum Maschinen Germany GmbH does not accept any guarantee for consequential dam-
age caused by unsuitable process abrasives. The flashpoint of the emulsion must be higher
than 140°C.
When using non-water-miscible cooling lubricants (oil content > 15%) with a flashpoint, ignitable
aerosol air mixtures might develop. There is a danger of explosion.
