SECTION 9:  MAINTAINING YOUR LAWN MOWER

WARNING:  Be sure to disconnect and
ground the spark plug wire before
performing any repairs or maintenance.

NOTE: When tipping the unit, empty the fuel tank and
keep engine spark plug side up.

Cutting Blade

WARNING:  When removing the cutting
blade for sharpening or replacement,
protect hands by using heavy gloves or a
rag to grasp the cutting blade. 

To remove blade

Remove the bolt and blade bell support which hold 
the blade and adapter to the engine crankshaft. 
See Figure 11. Remove the blade and the adapter 
from the crankshaft.

WARNING:  Periodically inspect the blade
adapter for cracks, especially if you strike
a foreign object. Replace when necessary.

Figure 11

When sharpening the blade, follow the original 
angle of grind as a guide. It is extremely important 
that each cutting edge receives an equal amount of 
grinding to prevent an unbalanced blade. An 
unbalanced blade will cause excessive vibration 
when rotating at high speeds, may cause damage 
to the mower and could break, causing personal 
injury.

The blade can be tested by balancing it on a round 
shaft screwdriver. Remove metal from the heavy 
side until it balances evenly. It is recommended that 
the blade always be removed from the adapter for 
the best test of balance.
