(2) Refer to Figure 6-1. Each blade clamp has two
lubrication fittings. Remove both lubrication fitting caps
and one of the lubrication fittings from each blade
clamp.
NOTE:
Certain old steel blade clamps may have only
one fitting, which must be carefully
re-lubricated without excessive pressure. Add
a small amount (1-2 fluid ounces) of grease
equally to each blade.
(3) Use a piece of safety wire to loosen any blockage
or hardened grease at the threaded holes where the
lubrication fitting was removed.
