•
When sharpening the blade, follow the original
angle of grind as a guide.
NOTE: It is extremely important that each cutting edge
receives an equal amount of grinding to prevent an
unbalanced blade. Such unbalanced blade will cause
excessive vibration when rotating at high speeds. It
may damage the mower, and/or cause personal injury.
•
Test the blade 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 when
testing for balance. Before reinstalling the blade
and the blade adapter to the unit, lubricate the
engine crankshaft and the inner surface of the
blade adapter with light oil.
•
Be sure to install the blade with the side of the
blade marked "Bottom" (or with part number) facing
the ground when the mower is in the operating
position. See Figure 19.

Maintain engine oil as instructed in the engine
manual. Follow all instructions carefully.
•
Service air cleaner every 25 hours under normal
conditions. Clean every few hours under extremely
dusty conditions. Poor engine performance and
flooding usually indicates that the air cleaner should
be serviced. To service the air cleaner, refer to the
engine manual.
•
The spark plug should be cleaned and the gap
reset once a season. Spark plug replacement is
recommended at the start of each mowing season.
Check engine manual for correct plug type and gap
specifications.

Clean engine regularly with a cloth or brush. Keep
the cooling system (blower housing area) clean to
permit proper air circulation which is essential to
engine performance and life. Remove all grass, dirt
and combustible debris from muffler area.
