3.1.2. CUTTING BLADE SERVICE
(Continued)
Sharpen Blade when the cutting edges
become dull if the blade is in otherwise
good condition. When dull, the grass cut
ends will be ragged and usually turn
brown soon after mowing.
CAUTION
The cutting blade has sharp edges which can cause
severe injury. Always wear heavy leather gloves
when handling blade to prevent injury.
1. Remove the blade by removing the
capscrew that secures it to blade
hub. Refer to Figure 20.
2. Sharpen it on a grinding wheel at an
angle of 22 to 28 degrees. The
cutting surface should extend in
about 7-1/2 inches from the tips. See
Figure 19.
3. Check the blade after sharpening to
determine that it is still balanced. It
will cause excessive vibration if
unbalanced.

4. Reinstall sharpened blade and related
components as shown in Figure 20.

5. Tighten the special blade retaining
cap screw to 25 to 35 foot-pounds
torque.
4.1 STORAGE PROCEDURE
Refer to the Engine Manual for directions
regarding engine storage preparations. Prepare
the mower for “end of season” storage as follows:
CAUTION
Use approved fuel container. DO NOT smoke near
open fuel container. DO NOT fill fuel tank indoors or
when engine is running. Wipe off any spilled fuel
before starting engine. Disconnect spark plug wire
from spark plug. Secure wire away from plug.
1. Remove fuel from fuel tank. Run engine until
carburetor bowl is empty.
2. Tape all openings closed to prevent spraying
water into exhaust or air intakes during
washing.
3. Stand the mower on its rear wheels and
thoroughly clean the underside of the deck.
Scrape away any accumulation of grass with a
putty knife and/or wire brush, then use a hose
to wash down the underside of deck and allow
to dry.
4. Lubricate all exposed metal with a light coating
of oil to prevent corrosion.
5. Drain oil and refill with new oil.
6. Change air filter. Refer to the Engine Owners
Manual Air Cleaner D section.
7. Store the mower in a shed or other dry area,
protected from weather.
NOTE
: Handles may be folded for storage. To fold
handles, loosen two T-Knobs, and fold the handle over
the mower. Use care not to “kink” the Blade Control
Cable or the 110 volt power cable.
