Changing the Engine Oil

Change the engine oil after the first 5 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. Perform the pre-maintenance procedures; refer to
Preparing for Maintenance.
2. Remove the dipstick (Figure 30).
Figure 30
3. Tip the mower onto its side, with the air filter up, to
drain the used oil out through the oil fill tube (Figure
31).

4. Slowly pour oil into the oil fill tube until the oil level
reaches the Full line on the dipstick (Figure 32). Do
not overfill. (Max. fill: 20 oz. (0.59 l), type: SAE 30W
detergent oil with an API service classification of SF,
SG, SH, SJ, SL, or higher.)

5. Install the dipstick securely.

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.
Refer to Preparing for Maintenance.
2. Tip the mower onto its side with the air filter up.
3. Use a block a wood to hold the blade steady (Figure 33).
