3. Install blade—sail facing toward cutting unit with

anti-scalp cup, lock washer, and blade bolt. Tighten
blade bolt to 85–110 ft.-lb.

Do not try to straighten a blade that is bent,
and never weld a broken or cracked blade.
Always use a new blade to ensure continued
safety certification of the product.

Warning

Inspecting And Sharpening
Blade

1. Raise cutting unit to highest position, shut the engine

off and engage the parking brake. Block cutting unit to
prevent it from falling accidentally.

2. Examine cutting ends of the blade carefully, especially

where the flat and curved parts of the blade meet
(Fig. 38-A). Since 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 machine. If
wear is noticed (Fig. 38-B), replace the blade: refer to
Removing Cutter Blade.

Danger

If blade is allowed to wear, a slot will form
between the sail and flat part of the blade
(Fig. 38-C). Eventually a piece of the blade
may break off and be thrown from under the
housing, possibly resulting in serious injury
to yourself or bystander.

Figure 38

3. Inspect cutting edges of all blades. Sharpen the cutting

edges if they are dull or nicked. Sharpen only the top of
the cutting edge and maintain the original cutting angle
to make sure of sharpness (Fig. 39). The blade will
remain balanced if same amount of metal is removed
from both cutting edges.

SHARPEN AT THIS

ANGLE ONLY

4. To check blade for being straight and parallel, lay blade

on a level surface and check its ends. Ends of blade
must be slightly lower than the center, and cutting edge
must be lower than the heel of the blade. This blade will
produce good quality of cut and require minimal power
from the engine. By contrast a blade that is higher at the
ends than the center, or if cutting edge is higher than the
heel, the blade is bent or warped and must be replaced.

5. Install blade—sail facing toward cutting unit with

anti-scalp cup, lock washer, and blade bolt. Tighten
blade bolt to 85–110 ft.-lb.
