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 and balanced, or replace it. The blade is sharp; contacting the blade can result in serious personal injury. Wear gloves when servicing the blade. 1. 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 19). Figure 20 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). 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. Figure 19 4. Remove the blade, saving all mounting hardware (Figure 19). 5. Install the new blade and all mounting hardware (Figure 20). 13
