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.
Refer to Preparing for Maintenance on page 12.
1. Remove the
dipstick.
2. Tip the mower onto
the right side to drain
the used oil out through
the oil fill tube.
3. Slowly pour oil into
the oil fill tube until the
oil level reaches the Full
line on the dipstick. Do
not overfill. (Max. fill:
20 oz., type: SAE 30W
detergent oil with an API
service classification of
SF, SG, SH, or SJ.)
4. Install the dipstick securely.
5. 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

Wear cloth or leather 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 on page 12.

60 ft-lb (82 N m).

very tight. While holding the blade with a block of
1018 wood, put your weight behind the ratchet or
wrench and tighten the bolt securely. This bolt is
very difficult to overtighten.
