Sharpening the Blade
File the top side of the blade to maintain its original cutting
angle (Fig. 24A) and inner cutting edge radius (Fig. 24B).
The blade will remain balanced if you remove the same
amount of material from both cutting edges.

Note: You can also check the balance using a commercially
manufactured, blade balancer.
2. If either end of the blade rotates downward, file that end
(not the cutting edge or the end near the cutting edge).
The blade is properly balanced when neither end drops.
Installing the Blade
1. Install a sharp, balanced Toro blade and the blade bolt.
Note: The sail part of the blade must point upward
(toward the top of the lawn mower housing).
2. Torque the blade bolt to 60 ft-lb (82 N
m).
3. Return the lawn mower to its upright position.
4. Connect the wire to the spark plug.

Cleaning the Cooling System

After every 100 operating hours or every season, clean the
dirt and the chaff from the cylinder, the cylinder head fins,
and around the carburetor and the linkage. Remove debris
from the air intake slots on the recoil housing. This will
ensure proper cooling and the best engine performance.

Emptying the Fuel Tank

1. Stop the engine and wait for it to cool.
Important Drain gasoline from a cold engine only.
2. Disconnect the wire from the spark plug (Fig. 10).
3. Remove the cap from the fuel tank (Fig. 8).
4. Use a hand pump to pump the gasoline into a clean
approved gasoline container.
5. Connect the wire to the spark plug.
6. Run the engine until it stops.
7. Start the engine again to ensure that all the gasoline is
out of the carburetor.
