off valve is open when the handle is aligned with the incom-

disconnect switch back “ON” to supply electrical power to
the equipment. (See illustration at right)
4. Using a suitable wiper or cloth shop towel, clean away the
old grease from the bottom surface of the lower carousel
plate. Use a small painters brush to apply white lithium
grease around the bottom of the lower carousel plate where
the index lift pistons make contact with the plate. Only a
small amount of grease is required. Excessive application of
grease will only serve to attract lint and other air borne con-
taminant’s to the index plate surface.

NOT PERFORMED ON A REGULAR BASIS AS LISTED,
THE TABLE LIFT CYLINDER PISTONS WILL SCORE A
GROVE INTO THE SURFACE OF THE CAROUSEL PLATE
CAUSING SEVERE AND PERMANENT DAMAGE!
