WARNING
The blade is sharp; contacting the blade can result
in serious personal injury.
• Disconnect the wire from the spark plug.
• Wear gloves when servicing the blade.
1. Disconnect the spark-plug wire from the spark plug.
Refer to Preparing for Maintenance (page 12).
2. Tip the machine onto its side, with the air filter up.
3. Use a block of wood to hold the blade steady.
4. Remove the blade (turn the blade bolt
counterclockwise), saving all the mounting
hardware.
5. Install the new blade (turn the blade bolt clockwise)
and all mounting hardware (Figure 24).
Figure 24
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.
Adjusting the Self-propel Drive
Cable
Whenever you install a new self-propel cable or if the
self-propel drive is out of adjustment, adjust the self-propel
drive cable.
1. Loosen the cable-support nut (Figure 25).

2. Hold the self-propel bail 25 to 38 mm (1 to 1-1/2
inches) from the handle (Figure 25).
3. Pull down the cable jacket (toward the machine) until
there is no slack in the cable (Figure 25).
4. Tighten the nut on the cable support.
5. Release the self-propel drive bar and ensure that the
cable is loose.
Note:
The cable must be loose with the self-propel
drive bar in the released position; otherwise, the
machine may creep when you disengage the bar.
