Check Mower Blade
1. Disconnect the spark plug wire and secure the end away
from the plug.
2. Tilt the mower up on its rear wheels for access to the blade
cap screw (A, Figure 22). Do not tilt the mower with the
spark plug or carburetor down.
NOTICE
Drain the fuel tank before tipping the mower. DO NOT tip the
machine with the carburetor or spark plug down. Oil from the
crankcase will saturate the air filter and cause the engine to
be hard to start or not start at all. If contamination does occur,
the air filter will have to be replaced.
3. Check the torque of the blade cap screw. Recommended
torque: 40 lb-ft (54 Nm).
4. Check the blade for sharpness, wear and damage. See
Blade Wear Limits
.
