OPERATION
OPERATING
TIPS
1.
2.
3.
4.
Check the attachment
clutch for correct adjustment.
For the
blade(s) to disengage correctly, the adjustment must be cor-
rect.
Before
you use the unit, check the oil in the engine
and add oil
if necessary.
If the engine will not start, first make sure the wire is attached
to the spark plug.
Make sure all the belts are inside all the belt guides.
See the in-
structions
on how to remove
and install
the motion
drive and
mower
drive belts.
5.
Before
you make an inspection,
adjustment
(except
for the car-
buretor)
or repair, make sure the wire from the spark plug is dis-
connected.
6.
Make sure the seat switch
wire is connected.
If the wire is not
connected,
the engine
will not start.
7.
For longer
life of the battery,
charge
the battery
every
three
months.
8.
Use the shift lever to change
the ground
speed,
not the throttle
control.
9.
Belt noise can occur when the blade or clutch is engaged.
This
noise is normal
and does not affect the operation
of the unit.
10. To move forward,
always
release the clutch/brake
pedal slowly.
MOWING
AND BAGGING
TIPS
1.
For a lawn to look better, check
the cutting
level of the mower
housing.
See "How To Level The Mower
Housing"
in the Ser-
vice And Adjustment
section.
2.
For the mower
housing
to cut level,
make sure the tires have
the correct
amount
of air pressure
(PSI) and use slow ground
speeds
when turning.
3.
Every time you use the unit, check the blade. If the blade is bent
or damaged,
immediately
replace
the blade.
Also,
make sure
the nut for the blade is tight.
4.
Keep the blade(s)
sharpened.
A worn
blade(s)
wil! cause the
ends
of the grass to turn brown.
5.
Do not cut or bag grass that is wet. Wet grass will not discharge
correctly.
Let the grass dry before cutting.
6.
Use the left side of the mower
housing
to trim near an object.
7.
Discharge
the cut grass
onto the mowed
area. The result is a
more even
discharge
of cut grass.
8.
When
you mow large areas,
start by turning
to the right so that
the cut grass will discharge
away from shrubs,
fences,
drive-
ways,
etc. After one or two rounds,
mow in the opposite
direc-
tion making
left turns
until finished
(Figure
18).
9.
Use a mowing
pattern
that eliminates
reverse
travel
as much
as possible.
10.
If the grass is very high, cut two times to decrease
the load on
the engine.
First cut with the mower housing
in the highest
posi-
tion and then lower the mower
housing
for the second
cut.
11.
For better
engine
performance
and an even discharge
of the
cut grass,
always
operate
the engine
with the throttle
in FAST
position.
12. When
you use a bagger, operate
the engine
with the throttle
in
FAST position
and the speed
control
lever
in a slow forward
speed.
13.
For better cutting
performance
and a quality
cut, mow in a slow
forward
speed.
14. After each use, clean the bottom
and top of the mower
housing
for better performance.
Also,
a clean mower
housing
will help
prevent
a fire.

MULCHING
TIPS
When
you use a mulcher
attachment,
the grass is cut into very small
4.
pieces.
These
small
pieces
will quickly
break
down.
Because
the
nutrients
are returned
to the soil, the lawn will need less fertilizer.
Too
correctly
mulch the grass, follow
the steps below.
1.
Set the throttle
in the FAST position.
Operate
the mower
at a
slower
ground
speed.
If ground speed
is too fast, the grass will
5.
not have an even cut.
2.
Keep a sharp
edge on the blade. A blade that is not sharp will
cause
the ends of the grass to become
brown.
6.
3.
Make sure the grass
is dry. Wet grass is difficult
to cut.
7.

21
Set the height
of the mower
housing
so that only the top third
of the grass
is cut. If the grass is too high, set the height of the
mower
housing
to the maximum
height. Then, lower the mower
housing
for the second
cut. Also, instead
of using the full width
of the mower
housing,
mulch at half the width.
Clean the bottom of the mower housing.
Grass and other debris
can keep the mower
from working
correctly.
If the grass
grows fast, mulch more often.
If an area needs
improvement,
mulch
a second
time.
