Standard Blade Wear Limit
1. Inspect the blade (Figure 11) frequently for signs of
excessive wear or damage:
(A) New blade
(B) Wear limit (notch starts)
(C) Dangerous condition! Do not use on the mower!
Replace with a new blade.
Blade Sharpening
1. Disconnect the spark plug wire and secure the end away
from the plug.
2. Tilt the mower up on its rear wheels. Do not tilt the
mower with the spark plug or carburetor down.
Important: 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. Remove the blade (B, Figure 12).
WARNING
DO NOT attempt any maintenance, adjustments or service
with engine and blade running. STOP engine and blade.
Disconnect spark plug wire and secure away from spark
plug. Engine and components are HOT. Avoid serious
burns, allow sufficient time for all components to cool.
Wear heavy leather gloves when handling or working
around cutting blades. Blades are extremely sharp and can
cause severe injury.
