Blade Service
WARNING: Before you inspect the
blade or the blade adapter, discon-
nect the wire to the spark plug. If
the blade hits an object, stop the engine.
Disconnect the wire to the spark plug.
Check the unit for damage.
Frequently check the blade for wear or damage
such as cracks. Frequently check the bolt that
holds the blade. Keep the bolt tight. If the blade
hits an object, stop the engine. Disconnect the
wire to the spark plug. Check the blade adapter
for damage. Check for a bent or damaged blade,
a badly worn blade, or other damage. Before
you operate the unit, damaged parts must be
replaced with factory replacement parts. For
safety, replace the blade every two years. Keep
a sharp edge on the blade. A blade that is not
sharp will cause the ends of the grass to be-
come brown. Remove the blade as follows.
How To Remove The Blade
(Figure 11 and Figure 12)
WARNING: Before you remove the
blade, disconnect the wire to the
spark plug. The blade has sharp
edges. When you hold the blade, use
gloves or cloth material to protect your
hands.
1. Drain the fuel tank.
2. Lift the side of the mower that has the muffler
or spark plug.
3. Use a piece of wood to keep the blade from
rotating.
4. Remove the bolt (1) that holds the blade (2).
5. Check the blade according to the “Blade Ser-
vice” instructions. Replace a badly worn or
damaged blade with a factory replacement
blade.
6. Mount the blade with the curved edges to-
ward the housing. If the blade is upside
down, the blade will not cut correctly and can
cause an accident.
7. Fasten the blade 2) with the original wash-
ers (3 and 4) and bolt (1). Make sure the
outside rims of the Belleville washers (4)
are toward the blade (2).
8. Tighten the bolt (1) that holds the blade (2)
to a torque of 30 foot pounds.
WARNING: Always keep the bolt
(1) that holds the blade (2) tight. A
loose bolt (1) or blade (2) can
cause an accident.
Check The Level Of Cut
Test the unit in a small area. If the height of cut
is not level or if the cut grass is not discharged,
the cause can be: (1) the blade is bent or dam-
aged, (2) the blade is not sharp, (3) a worn
blade, (4) or a broken blade adapter. Before you
use the unit, correct the problem.
How To Prepare The Mower For Storage
WARNING: Do not remove gasoline
while inside a building, near a fire,
or while you smoke. Gasoline
fumes can cause an explosion or a fire.
1. Drain the fuel tank.
2. Let the engine run until it is out of fuel.
3. Drain the oil from the warm engine. Fill the
engine crankcase with new oil.
4. Remove the spark plug from the cylinder.
Pour one ounce of oil into the cylinder. Slow-
ly pull the recoil--start grip so that the oil will
protect the cylinder. Install a new spark plug
in the cylinder.
5. Clean the dirt and debris from the cylinder
cooling fins and the engine housing.
6. Clean the bottom of the mower housing.
7. Completely clean the mower to protect the
paint.
