Replacing the Blade
Service Interval:
Before each use or daily
Every 25 hours—Replace the blade
or have it sharpened (more frequently
if the edge dulls quickly).
Important:
You will need a torque wrench to install
the blade properly
. If you do not have a torque
wrench or are uncomfortable performing this
procedure, contact an Authorized Service Dealer.
Examine the blade whenever you run out of gasoline. If
the blade is damaged or cracked, replace it immediately.
If the blade edge is dull or nicked, have it sharpened or
replace it.
WARNING
The blade is sharp; contacting the blade can result
in serious personal injury.
Wear gloves when servicing the blade.

Figure 42
4. Remove the blade, saving all mounting hardware.
5. Install the new blade and all mounting hardware.
Important:
Position the curved ends of the
blade to point toward the mower housing.

60 ft-lb (82 N-m).
Important:
A bolt torqued to 60 ft-lb (82 N-m)
is very tight. While holding the blade with a
block of wood, put your weight behind the
ratchet or wrench and tighten the bolt securely.
This bolt is very difficult to overtighten.
