the black cable mount and measure how far the upper
end of the cable jacket moves (Figure 44).

1. Cable mount
Note: Moving the cable jacket upward decreases the
ground speed; moving the jacket downward increases
the ground speed.
5. Tighten the nut firmly.
6. Start the machine and check the adjustment.
Note: If the self-propel drive is not properly adjusted,
repeat this procedure.
Replacing the Blade
Service Interval: Yearly or before storage
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 (page 14).
2. Tip the machine onto the side with the dipstick down.
3. Use a block of wood to hold the blade steady
(Figure 45).

4. Remove the blade, saving all mounting hardware
(Figure 45).
5. Install the new blade and all mounting hardware
(Figure 45).
Important: Position the curved ends of the blade
to point toward the machine housing.
6. Use a torque wrench to tighten the blade bolt to 82
N-m (60 ft-lb).
Important: A bolt torqued to 82 N-m (60 ft-lb) 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 Underside of the
Machine Housing
Service Interval: Before each use or daily
WARNING
The machine may dislodge material from under the
machine housing.
• Wear eye protection.
• Stay in the operating position (behind the
handle).
• Do not allow bystanders in the area.
1. With the engine running on a flat paved surface, spray
a stream of water in front of the right rear wheel
(Figure 46).
Note: The water will splash into the path of the blade,
cleaning out the clippings.
