How To Clean The Mower Housing
WARNING: The blade will rotate
when the engine runs. Before you
clean the mower housing, stop the
engine and disconnect the wire from the
spark plug.
Grass and other debris can keep the mower
from working correctly. After you mow, clean the
mower housing as follows.
1. Stop the engine.
2. Disconnect the wire from the spark plug.
3. Clean the top and the bottom of the mower
housing.
How To Adjust The Height Of Cut
WARNING: The blade will rotate
when the engine runs. Before you
change the height of cut, discon-
nect the wire to the spark plug.
Models With Quick Type Adjusters
(Figure 7)
To change the height of cut, move the position of
the adjuster arm (1) at each wheel. Make sure
each adjuster arm (1) is in the same position so
that the mower will cut level.
1. Disengage the adjuster arm (1).
2. Move the adjuster arm (1) to another posi-
tion.
Mulching Blade Replacement
A mulching mower is equipped with a special
mulching blade. If the mulching blade becomes
worn or damaged, replace with an original
equipment mulching blade. A standard blade will
not cut correctly and could cause an accident.
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
become brown. Remove the blade as follows.
How To Remove The Blade (Figure 10
and Figure 11)
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
damaged, (2) the blade is not sharp, (3) a worn
blade, (4) or a broken blade adapter. Before you
use the unit, correct the problem.
Folding Handle Storage (Figure 12 and
Figure 13)
CAUTION: Be careful when you fold or raise
the handle. Do not damage the cables. A
cable that is bent will not work correctly. Be-
fore you use the unit, replace a bent or dam-
aged cable.
How To Fold The Handle
1. (Figure 12) Loosen the fasteners that hold
the upper part of the handle to the lower part
of the handle. As you fold the handle, make
sure the cables are not around the loose fas-
teners and do not become damaged. Rotate
the upper part of the handle toward the back
of the unit.
2. (Figure 13) Remove the hair pins (3) from
the lower handle (1). Push in on the ends of
the lower handle (1). Move the ends of the
lower handle (1) past the locking pins (2)
or locking tabs (2).
3. Rotate the handle forward over the engine.
Make sure the cables are not damaged.
How To Raise The Handle
1. Pull the handle back until the ends of the
lower handle (1) lock into position.
2. Lift the upper part of the handle into the oper-
ator's position. Tighten the fasteners that
hold the handle.

How To Prepare The Mower For Storage
WARNING: Do not remove petrol
while inside a building, near a fire,
or while you smoke. Petrol fumes
can cause an explosion or a fire.
1. Drain the fuel tank.
2. Let the engine run until it is out of petrol.
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.
8. Put the unit in a building that has good ven-
tilation.
9. Make sure the grass bag is empty of grass.
Grass remaining in the bag during storage
will damage the bag.
