Blade

A straight sharp blade provides maximum cutting
performance. Regularly inspect and sharpen blade.
POTENTIAL HAZARD
Blade is sharp.
WHAT CAN HAPPEN
Contact with sharp blade can cause serious
personal injury.
HOW TO AVOID THE HAZARD
Wear gloves or wrap sharp edges of the
blade with a rag.
1. Drain gasoline from fuel tank. See Drain
Gasoline section.
2. Run engine until it dies. Try starting engine once
more to make sure gas is out of carburetor.
3. Pull wire off spark plug (Fig. 9).
4. Tip mower on its left side. Avoid rotating blade
as starting problems may result.
5. INSPECTING BLADE—Carefully examine
blade for sharpness and wear, especially where
flat and curved parts meet (Fig. 26A). Since sand
and abrasive material can wear away the metal
that connects the flat and curved parts of the
blade, check blade before using the mower. If a
slot or wear is noticed, (Fig. 26B & C), replace
blade. Refer to step 6.
6. REMOVING BLADE—Grasp end of blade
using a rag or thickly padded glove. Remove
blade nuts, anti–scalp cup, blade, blade spacer
and rotating screen (Fig. 27).
