Delta Blades
Wear/Replacing
Over time and due to wear, the blades will diminish in
length. Once the blades have worn down by about ¾"
(19 mm), the overall length of the blade at the longest
point of the blade will be about 2½" (64 mm), and it will
be necessary to replace the blades.
It is possible to replace delta blades without removing
the rotor shaft. Remove the delta blade by removing
the two screws with nuts holding the blade in place.
Turn the new blade until it is properly aligned; see
illustration.
