SERVICING THE ECCENTRIC BEARING
NOTE: For model 6603 only.
Once every three months (depending on usage), remove the shear head
from the power unit following the instructions in the "REPLACING
CUTTERS" section of the manual.
Disconnect the tool from the power source before dis-
assembling.
Put a few drops of heavy oil on the eccentric bearing assembly (A) Fig. 4, so
that it saturates the needle bearing. The outside surface of the eccentric
bearing ring and the yoke of the center blade should be coated with bearing
lubricant.
