Mast Drive Screw Lubrication

To keep the mast assembly operating smoothly and efficiently,
the outer and mid-mast drive screws must be lubricated annu-
ally.
There are three (3) access covers on the upper portion of the
outer mast section, one on each side, and one on the back of
the mast.
Only two (2) covers must be removed to lubricate the mast drive
screws, the cover on the rear, and the cover on the auxiliary
drive port (right) side of the mast. (See Figure 6-3.)
