Replacing the Blade
Service Interval: Yearly
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.
1. Disconnect the spark plug wire from the spark plug.
Refer to Preparing for Maintenance.
2. Tip the mower onto its side, with the air filter up.
3. Use a block of wood to hold the blade steady
(Figure 39).
4. Remove the blade, saving all mounting hardware
(Figure 39).
5. Install the new blade and all mounting hardware
(Figure 39).
Important: Position the curved ends of the
blade to point toward the mower housing.
6. Use a torque wrench to tighten the blade bolt to
60 ft-lb (82 N-m).
Figure 39
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.
Cleaning the Mower
Service Interval: Before each use or daily
WARNING
The mower may dislodge material from under the
mower housing.
• Wear eye protection.

1. With the engine running on a flat paved surface,
spray a stream of water in front of the right rear
wheel (Figure 40).
Note: The water will splash into the path of the
blade, cleaning out the clippings.
2. When no more clippings come out, stop the water
and move the mower to a dry area.
3. Run the engine for a few minutes to dry the housing
to prevent it from rusting.
