4.1 MOWER BLADE REPLACEMENT
4.1.1. STANDARD BLADE WEAR LIMIT
1. Inspect blade frequently for signs of excessive
wear or damage. See Figure 4.1.
4.1.2. BLADE SHARPENING
1. Disconnect spark plug wire and secure end away
from plug.
IMPORTANT: Drain fuel tank before tipping mower. DO
NOT tip machine with carburetor or spark plug down. Oil
from 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.
2. Tilt mower up on its rear wheels. Do not tilt mower
with spark plug or carburetor down.
3. Remove blade. See Figure 4.2.

inspection and service procedures.
