POTENTIAL HAZARD
A worn or damaged blade could break and
a piece of blade could be thrown into
operator's or bystander's area.
WHAT CAN HAPPEN

personal injury or death to operator or
bystanders.
HOW TO AVOID THE HAZARD

damage.

5.
REMOVING BLADE—Grasp end of blade
using a rag or thickly padded glove. Remove
blade nuts, anti–scalp cup, accelerator, and blade
(Fig. 24).
6.
SHARPENING BLADE—Using a file, sharpen
top side of blade and maintain original cutting
angle (Fig. 26). The blade will remain balanced
if same amount of material is removed from both
cutting edges.
IMPORTANT: Check balance of blade by
putting it on a blade balancer. An inexpensive
balancer can be purchased at a hardware
store. A balanced blade stays in a horizontal
position and an unbalanced blade settles to
the heavy side. If blade is not balanced, file
more metal off cutting edge on heavy end of
blade.
7.
Reinstall sharp, balanced blade, blade
accelerator, anti–scalp cup, and blade nuts. Sail
part of blade must point toward top of mower
housing to assure correct installation. Tighten
blade nuts to 15–27 ft–lbs (20–37 N m).
