POTENTIAL HAZARD
• Operating the lawn mower without the
accelerator in place can cause the blade to flex,
bend, or break.
WHAT CAN HAPPEN
Sharpening the Blade
•
A broken blade could cause serious injury or
death to the operator or bystanders.
File the top side of the blade to maintain its original
cutting angle (Fig. 20A) and inner cutting edge radius
(Fig. 20B).
HOW TO AVOID THE HAZARD

Do not operate the lawn mower without the
accelerator.

1.
Wipe the grease fittings on the rear wheel height
adjustment levers with a clean rag (Fig. 22).
Note: The blade will remain balanced if you remove the
same amount of material from both cutting edges.
Balancing the Blade
1.
Check the balance of the blade by placing the center
hole of the blade over a nail or a screwdriver shank
clamped horizontally in a vise (Fig. 21).

IMPORTANT: Excess grease may prevent the wheel
clutch operation from properly operating.
Note: You can also check the balance by using a
commercially manufactured blade balancer.
Adjusting the Self-propel Drive
Cable
2.
If either end of the blade rotates downward, file that
end (not the cutting edge or the end near the cutting
edge). The blade is properly balanced when neither
end drops.
If the top speed begins to slow down on the lawn mower,
adjust the self-propel drive cable.
