4. REAR SHIELD
During normal use, the rear shield is subject to
deterioration and wear. Remove the grass bag and
raise the discharge guard. Check the rear shield for
cracks or tears. If the rear shield is worn, replace it.
To remove the shield, pry the push nut off the shaft
using a flat blade screwdriver. If the shaft is crimped
at the end, cut the shaft with a small hacksaw and
replace the shaft.
5. BLADES
INSPECTION
(K9~K11 Blades Shown)
1. Turn the fuel valve to the OFF position. This will reduce the
possibility of fuel leakage when the mower is tilted.
2. Disconnect the spark plug cap.
3. Tilt the mower on its right side, so the carburetor is up.
4. Inspect the blades for damage, cracks, and excessive wear,
rust, or corrosion.
5. Verify the blade bolts are tight.
6. If the blades are bent or severely damaged, check the
crankshaft runout (
).
7. Dull blades can be sharpened, but blades that
are worn out, bent, cracked, or otherwise
damaged must be replaced.
