BLADE/BLADE FLANGE CARE (CONT'D)
NOTE: The blade flange with fab attaches the
blade to crankshaft. It is not intended to protect
the crankshaft. The tab must be in good condition
and located in slot of crankshaft to keep blade
attached.
5. Put the blade flange on the engine crankshaft
with the tab in the slot of the crankshaft (See
Fig. 19).
6. Put the blade on the crankshaft as shown in
(Fig. 19). Be sure the word "TOP" (stamped
in the blade) is toward the engine.
7. Install the flat washer, two (2) formed washers
and blade nut as removed above.
NOTE: We recommend that the blade nut be re­
placed when installing a new blade.
8. Tighten blade nut. The recommended tighten­
ing torque is 50-65 ft. lbs. Use block of wood
to prevent blade rotation.
NOTE: Torque wrenches are available at most
Sears retail stores and through the catalog.
A loose blade can result in difficult starting of
engine.
We do not recommend sharpening blade-but if
you do, be sure blade is balanced. An unbalanced
blade can cause excessive vibration and contri­
bute to shortening the life of the engine and
mower.
REAR DEFLECTOR
The rear deflector which is attached to the rear of
your mower is to keep objects from being thrown
out the back of the mower. If your rear deflector
becomes damaged you should replace if (See
Fig. 20).
