Fill the container of the coolant circuit with your process abrasive.
The total filling quantity in the circuit must not exceed the height of the sedimentation tank for
the grinding sludge.

Connect the coolant return hose to the surface grinding machine and feed it into the cool-
ant tank. The attachment takes place by means of hose clamps.
3.10 Electrical connection
CAUTION!
Must only be worked on by a qualified electrician or person working under the
instructions and supervision of a qualified electrician.
The grinding wheel must rotate clockwise.
If the grinding wheel rotates in the wrong direction, the grinding wheel can become
detached from the shaft during the grinding process.
If necessary, two phase connections in the switch cabinet must be exchanged. The guarantee
will become null and void if the machine is connected incorrectly.
CAUTION!
Arrange the machine's connection cable in such a way that it will not cause a tripping
hazard.
Please verify if the type of current, voltage and protection fuse correspond to the values speci-
fied. A protective earth ground wire connection must be available.
When the surface grinding machine is connected to a ~60Hz mains supply, the speed of the
grinding wheel increases 1.2 times.

WARNING!
First commissioning may only take place after proper installation.
When the surface grinding machine is first put into operation by inexperienced
personnel or inexperienced users, you endanger people and equipment. We do not
accept any liability for damages caused by incorrectly performed commissioning.
ATTENTION!
Before commissioning the machine, all bolts, fastenings and protections must be
checked and retightened as necessary!
ATTENTION!
Before putting the machine into operation, the fill levels must first be checked.

Central lubrication
Make sure that the slideway oil reaches the lubrication points.
3.11.1 Warming up the machine
ATTENTION!
If the surface grinding machine, in particular the grinding spindle, is immediately
operated under grinding load when it has cooled down, it may be damaged. A machine
that has cooled down, such as may occur immediately after transport, should therefore
be warmed up first for the first 20 minutes without grinding load.
