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.
• 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 10).
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 18).
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
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.
Cleaning the underside of the
Machine
Service Interval: After each use
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 19).
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 machine to a dry area.
3. Run the engine for a few minutes to dry the housing
to prevent it from rusting.
