Lubricate before commissioning the chuck
Before commissioning, move the chuck in the open position. Press
three strokes SCHUNK special grease LINOMAX into each of the
grease nipples using a high-pressure grease gun. To achieve the
optimal grease distribution and the maximum clamping force,
close and open the chuck several times over the entire clamping
stroke. Check the clamping force and, if necessary, repeat the lu-
brication process.
