Maintaining the Blade
A straight, sharp blade provides the best cutting
performance. Regularly inspect and sharpen the blade.
WARNING
POTENTIAL HAZARD
The blade is sharp.
WHAT CAN HAPPEN
Contact with a sharp blade can cause serious
personal injury.
HOW TO AVOID THE HAZARD
Wear gloves or wrap the sharp edges of the
blade with a rag.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug (Fig. 6).
WARNING
POTENTIAL HAZARD
Gasoline is extremely flammable, highly
explosive and under certain conditions can
cause personal injury or property damage.
WHAT CAN HAPPEN
Tipping the lawn mower may cause fuel leakage
from the carburetor or fuel tank.
HOW TO AVOID THE HAZARD
Avoid fuel spills by running the engine dry or
removing gas with a hand pump; never siphon.
3. Drain the gasoline from the fuel tank. Refer to the
Emptying the Fuel Tank on page 20.
4. Tip the lawn mower on its left side (Fig. 21).
Figure 21
IMPORTANT: Move the blade as little as possible to
avoid future staring problems.
Inspecting the Blade
Carefully examine the blade for sharpness and wear,
especially where the flat and the curved parts meet
(Fig. 22A). Because sand and abrasive material can wear
away the metal that connects the flat and curved parts of
the blade, check the blade before using the lawn mower. If
you notice a slot or wear (Figs. 22B and 22C), replace the
blade; refer to Removing the Blade on page 17.

2. Flat part of blade
Note: For the best performance, install a new blade before
the cutting season begins. During the year, file down any
small nicks to maintain the cutting edge.
POTENTIAL HAZARD
A worn or damaged blade could break and a
piece of the blade could be thrown into the
operator's or bystander's area.
WHAT CAN HAPPEN
A thrown piece of the blade could cause serious
personal injury or death to the operator or
bystanders.
HOW TO AVOID THE HAZARD
Inspect the blade periodically for wear or
damage.
Replace a worn or damaged blade.
