oil-fill tube, and then repeat steps 10 through 12
until the oil level is at the Full mark on the dipstick.
•
If the oil level is above the Full mark on the
dipstick, drain the excess oil until the oil level is at
the Full mark on the dipstick.
Important: If the oil level in the crankcase is
too low or too high and you run the engine,
you may damage the engine.
13. Install the dipstick securely by hand.

Replacing the Blade
Service Interval: Yearly or before storage
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.
WARNING
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 (page 13).
2. Tip the machine onto its side, with the air filter up.
3. Use a block of wood to hold the blade steady
(Figure 35).
4. Remove the blade, saving all mounting hardware
(Figure 35).
Figure 35
5. Install the new blade and all mounting hardware
(Figure 36).
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.
Cleaning the Underside of the
Machine Housing
Service Interval: Before each use or daily
