Frank COBRA C Operating Instructions Manual page 24

Because of the space needed for the person operating the machine and the machine itself, the
floor is not sanded over an area of approximately 1.5 m to the wall behind the sander.
Turn the machine 180° and sand the remaining area of the floor also in sanding paths which are
arranged overlappingly from left to right. Make sure that the two areas are blended together
without leaving any marks.
Note!
In most cases, the floor is sanded in several procedures. The whole floor area is sanded down
in every sanding procedure.
Informations about the proper abrasive grits, sanding pressures and sanding directions for the
several sanding procedures you will find in the brochure:
