Changing the Engine Oil
Change the engine oil after the first 2 operating hours; change it yearly thereafter.
Run the engine a few minutes before changing the oil to warm it. Warm oil flows better and carries more contaminants.
1.Refer to Preparing for Maintenance.
2.Remove the dipstick (Figure 29).
Figure 29
3.Tip the mower onto the right side to drain the used oil out through the oil fill tube (Figure 30).
Figure 30
4.Slowly pour oil into the oil fill tube until the oil level reaches the Full line on the dipstick (Figure 31). Do not overfill. (Max. fill: 20 oz., type: SAE 30W detergent oil with an API service classification of SF, SG, SH, SJ, SL, or higher.)

5.Install the dipstick securely.
6.Dispose of the used oil properly at a local recycling center.

Replacing the Blade
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.
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 and hook it onto the retaining post. 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 33).
Figure 33
4.Remove the blade, saving all mounting hardware (Figure 33).
