CONTROLLING
SPEED
AND
TILLING
DEPTH
The
tiller
has
eight
10-mch
diameter,
spring
steel
tines.
Tine
speed
is
160
RPM
The
normal
tilling
depth
is4V2
inches
deep.
It
may
be
changed
by
adjusting
the
depth
bar
and
pressure
exerted
on
the
handles.
The
tilling
width
may
also
be
varied.
See
adjustment
section.
Throttle
Control
The
throttle
control
lever
is
located
on
the
right
hand
side
of
handle.
ADJUSTMENTS
WARNING
Disconnect
the
spark
plug
wire
from
spark
plug
and
ground
against
the
engine
block
{secure
in
“V"
slot)
before
making
any
adjustments
or
performing
maintenance.
See
fig¬
ure
8.
NOTE
Right
hand
side
is
determined
from
the
operator's
position
standing
be¬
hind
the
tiller.
The
throttle
control
lever
adjusts
the
engine
speed.
It
also
gives
finger
tip
control
of
the
carburetor
and
magneto
stop
switch.
With
the
throttle
control
knob
pushed
completely
forward,
the
carburetor
is
in
FAST
position.
Pulling
the
throttle
control
back
slightly
adjusts
the
engine
speed
to
START.
Pulling
the
throttle
back
further
reduces
the
engine
speed
to
SLOW.
When
the
throttle
is
pulled
completely
back,
the
magneto
stop
switch
grounds
out
the
spark
and
stops
the
engine.
Move
the
throttle
control
to
slow
when
transporting
the
tiller.
When
the
tiller
is
being
moved
to
or
from
the
garden,
the
depth
bar
should
be
raised
up
until
it
clears
the
ground.
The
machine
may
be
moved
under
its
own
power,
without
damaging
grass
areas
as
long
as
it
is
allowed
to
move
freely.
If
the
operator
holds
back,
it
will
start
to
dig.
Depth
Bar
The
depth
bar
acts
as
a
brake
for
the
tiller
and
con¬
trols
the
depth
and
speed
at
which
the
machine
will
operate.
You
may
till
deeper
by
moving
the
depth
bar
all
the
way
down.
See
adjustment
section.
Handle
Pressure
Further
control
of
tilling
depth
and
travel
speed
can
be
obtained
by
variation
of
pressure
on
the
handle.
A
downward
pressure
on
the
handle
will
reduce
the
work¬
ing
depth
and
increase
the
forward
speed.
An
upward
pressure
on
the
handle
will
increase
the
working
depth
and
reduce
the
forward
speed.
The
type
of
soil
and
working
conditions
will
determine
the
actual
setting
of
the
depth
bar
and
the
handle
pressure
required.
HANDLE
POSITION
The
upper
handle
can
be
adjusted
to
two
different
heights.
The
operator
of
the
tiller
can
easily
adjust
the
handle
position
by
unscrewing
the
two
knobs,
remov¬
ing
the
two
bolts
and
reassembling
in
another
position.
No
tools
are
necessary
to
make
this
adjustment.

MAINTENANCE
A
Disconnect
the
spark
plug
wire
from
spark
plug
and
ground
against
the
engine
block
(secure
in
“V”
slot)
before
performing
any
maintenance.
See
figure
8.
CLEAN
ENGINE
Wipe
off
all
spilled
fuel
and
oil.
Keep
the
engine
clean
of
foreign
matter
and
be
sure
the
cooling
fins
on
the
cylinder
are
kept
clean
to
permit
proper
air
circulation.
This
is
an
air
cooled
engine
and
free
flow
of
air
is
essen¬
tial
to
proper
engine
performance
and
life.
ENGINE
OIL
Check
oil
level
before
each
use.
Be
sure
oil
level
is
maintained
full
to
point
of
overflowing.
See
figure
19.
FIGURE
19.
Change
the
oil
in
the
crankcase
after
the
first
two
hours
of
operation
of
your
new
engine
and
after
each
25
hours
of
use
thereafter.
This
will
ensure
proper
lubrication
of
internal
parts
to
prevent
excessive
wear.
To
change
the
oil,
remove
drain
plug
and
tip
the

new
oil
of
proper
grade.
Replace
filler
cap.
AIR
CLEANER
Service
the
air
cleaner
every
25
hours
of
operation.
The
air
cleaner
prevents

from
•
entering
the
carburetor
and
being
forced
into
the
engine.
It
is
important
to
engine
life
and
performance.
To
service
air
cleaner,
refer
to
the
engine
manual
packed
with
the

without
air
cleaner
com¬
pletely
assembled.

Spark
plug
replacement
is
recommended
at
the
start
of
