LOOSEN SCREWS AND REMOVE RINGS
Unscrew 3/8” blade socket cap screws until flush with inside of
socket. Unscrew jam nuts back to near heads of cap screws. Re-
move lock screws in top and bottom retainer rings (See Figure 1).
Mark ring and blade socket at center to indicate where lock screw
goes. Use retainer ring tool to remove individual blade retainer
ring halves. Insert end of tool into hole in end of retainer ring half
and pry ring out of blade socket. (Note: If tool is not available, a
1/4” hook bent on the end of a piece of 1/8” diameter wire
works).

sockets, use our H-blade adapter (P/N K2300). Install both halves
of adapter over blade. Make sure flange of blade is against inside
shoulder of adapter. Tighten 3/8” cap screws to 30-35 ft-lb torque
(See Figure 2).

BLADE INSTALLATION
Place blade in hub socket. Insert blade shank into socket far
enough to allow blade retainer ring halves to be “snapped” into
place (See Figure 3). If you are using the H-blade adapter with
Tuf-Lite II
®
blades, make sure that the split in the adapter is
horizontal. Position the blades’ thick leading edge to the left
and thin trailing edge to the right as you stand at the end of the
blade.

groove with end of screwdriver as shown in Figure 4.
