INSPECTING BLADE—Carefully examine
blade for sharpness and wear, especially where
flat and curved parts meet (Fig. 24A). 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. 24B & C), replace
blade. Refer to step 5.
Note:
For best performance, install new blade
before cutting season begins. During
the year, file down small nicks to
maintain the cutting edge.
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
A thrown piece of blade could cause serious
personal injury or death to operator or
bystanders.
HOW TO AVOID THE HAZARD
Inspect blade periodically for wear or
damage.
Replace a worn or damaged blade.

Lubrication
After every 25 operating hours or when season ends,
pivot arms must be lubricated.
1.
REMOVING BLADE—Grasp end of blade
using a rag or thickly padded glove. Remove
blade nuts, anti–scalp cup, accelerator, and blade
(Fig. 23).
SHARPENING BLADE—Using a file, sharpen
top side of blade and maintain original cutting
angle (Fig. 25). 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.
Reinstall sharp, balanced blade, accelerator,
anti–scalp cup, and blade nuts. Sail part of blade
must point toward top of mower housing to
ensure correct installation. Tighten blade nuts to
15–27 ft–lb (20–37 N m).
Operating mower without accelerator in
place could cause blade to flex, bend or
break.
A broken blade could cause serious injury
or death to operator or bystanders.
Do not operate mower without accelerator.
Move rear wheel height–of–cut levers to center
setting. Wipe grease fittings with clean rag
(Fig. 26). Install grease gun onto fitting and
