•
If the oil level is low, add a small amount of oil
slowly to the oil-fill tube, and then repeat steps
6 through 8 until the oil level on the dipstick is
correct.
•
If the oil level is high, drain the excess oil until the
oil level on the dipstick is correct.
Important:
If the oil level in the crankcase is
too low or too high and you run the engine,
you may damage the engine.
9. Install the dipstick securely.
10. Recycle the used oil properly.
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.
1. Disconnect the spark-plug wire from the spark plug.
Refer to
Preparing for Maintenance (page 11) .
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 23 ).
Figure 23
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 82
N-m (60 ft-lb).
Important:
A bolt torqued to 82 N-m (60 ft-lb) 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.
Adjusting the Self-Propel Drive
Whenever you install a new self-propel cable or if the
self-propel drive is out of adjustment, adjust the self-propel
drive.
1. Turn the adjustment knob counterclockwise to loosen
the cable adjustment (

Note:
Push the cable toward the engine to increase
the traction; pull the cable away from the engine to
decrease the traction.
3. Turn the adjustment knob clockwise to tighten the
cable adjustment.
Note:
Tighten the knob firmly by hand.
