Here’s your new MANTIS Tiller . . .
the lightweight wonder that “Makes
Gardening Easier.”
Unlike big tillers, your MANTIS Tiller
weighs only 20 pounds. So it lifts
easily, handles smoothly, tills and
weeds precisely. And, unlike other
small tillers, it features serpentine tines
that churn soil to ten inches deep. It
creates a soft, smooth seed bed, even
in problem soil.
Once you know how to use your tiller
correctly, we guarantee you’ll love it.
So first, please read this manual. It
shows, step by step, how to use your
tiller safely. Plus, it shows how the
MANTIS Border Edger can make light
work of your edging needs.
If you have questions about any topic
in this Manual, or if you wish to order
MANTIS Attachments, contact your
local authorized Mantis dealer.

Your MANTIS Tiller comes partially
assembled. You must install only the
handlebars, the carrying handle, and the
tines. This will take just a few minutes if
you follow the directions.
First, take all items out of the
carton. But do not remove the cardboard
from around the Tiller’s base.
The list at the right, shows the parts
that come with your tiller. Check to make
sure you have them.
The bag of hardware is in the plastic
bag containing the Owner’s Manual.
To assemble your MANTIS Tiller, you’ll
need two 7/16” wrenches or two
adjustable wrenches. We suggest that you
install all nuts and bolts only “finger
tight”
— that is, one-half to one full
turn — until you’ve completed
assembly. The nuts are self locking,
but you must use a wrench to tighten
them completely.

WARNING • DANGER
FUEL IS EXTREMELY FLAMMABLE. HANDLE IT WITH
CARE. KEEP AWAY FROM IGNITION SOURCES. DO NOT
SMOKE WHILE FUELING YOUR EQUIPMENT.
Assembling the Tines
for Tilling
1. Remove the cardboard
from around your Tiller’s base.
2. Slide the tines onto the
axle shafts. The “D” hole goes
on the outside.
3. Make sure you’ve installed
the tines properly for tilling.
Liken the tines to your fingers.
When your palm faces the
ground, your fingers curl down.
Stand behind the Tiller and
hold your hand next to the
tines. Do the tine blades curl
down, as your fingers do? If so,
they are in the tilling position.
(To switch to the cultivating
position, see page 15.)
4. To secure each tine to the
axle, insert a tine retaining pin.
IMPORTANT NOTE:
Before you use your
MANTIS Tiller, read the
Safety Rules & Warnings
on pages 3-5.
Here’s how to mix one gallon of
fuel:
1. Pour 1/2 gal. of the gasoline
into a safe container. Do not mix
the fuel and oil in the engine
fuel tank.
2. Add 2.6 ounces of twocycle engine oil to the gasoline
and mix. Then add the rest of
the gasoline.(1/2 gal.)
3. Screw the cap onto the
gasoline can. Then swirl the can
to blend the oil and gas.
4. Carefully pour the fuel mix
into the tiller’s fuel tank. After
putting the fuel tank’s cap back
on, wipe up any spilled fuel
from tank and gasoline can.
IMPORTANT:
Two stroke fuel separates and
ages. Do not mix more than you
will use in a month. Using old
fuel can cause difficult starting
or engine damage. Shake fuel
container to thoroughly mix fuel
before each use. Do not attempt
to run your engine on gasoline
only, use proper fuel mixture.
Need more pre-measured
engine oil? Contact your local
authorized Mantis Dealer.
Remember …
•Always mix two-cycle oil with
gasoline before fueling your
tiller. Never, ever run your tiller
on gasoline alone. This will ruin
your engine and void all
warranties.
•Always use a clean gas can and
always use unleaded gas.
•Never try to mix the oil and
gasoline in the engine fuel tank.
•Always mix oil and gas in the
proper proportions: 2.6 ounces
of two-cycle engine oil to one
gallon of unleaded gasoline.
IMPORTANT NOTE:
Do Not use old or stale
oil/gasoline mixture.
Always use the proper
oil/gasoline mixture. If you
do not, your engine will
suffer rapid, permanent
damage. And you will void
the engine warranty.
!
!
Mixing Fuel
Your MANTIS Tiller is powered by
a commercial two stroke, air cooled
engine which requires a fuel mixture
of gasoline and lubricating oil.
Use a mixture of 50 parts unleaded
regular gasoline and 1 part two-stroke
MANTIS oil (50:1.) Use branded 89 octane (R+M+2) unleaded gasoline
or gasohol (maximum 10% ethyl alcohol, or 15% MTBE, no methyl
alcohol.)
1 gallon
2.6 oz. bottle of
Mantis 50:1 2-cycle engine oil
Page 10

Never use starting
fluids as they will
cause permanent
engine damage.
Using them will
void the warranty.
Before you use the
tiller, read the
Safety & Warning
rules on pages 3-5.

STARTING
To Start Your Tiller for
the First Time:
1. Fill the fuel tank with the
proper oil/gasoline mixture.
(See previous section.)
2. Hand tighten the gasoline
cap just until it’s snug.
3. Place the o/
I switch into
the
I “start” position. (Picture 1)
4. Pull the choke button all
the way out, to completely close
the choke. (Picture 2)
5. Locate the purge bulb on
the upper right of the engine, in
front of the fuel tank. (See
Picture 3) It sends fuel into the
carburetor, for easy starting.
Press the purge bulb until you
see fuel flow through the clear
fuel return line. Since you’re
starting “cold,” you may need to
press six to eight times. As soon
as fuel starts flowing through
the clear fuel line, stop pressing!
(Picture 3)
6. Don’t press the throttle
trigger during the starting of the
engine.
7. Pull the starter cord
(Picture 4) until resistance is
felt. Then give the recoil starter
cord a few
brisk pulls until the
engine fires. Note: Pull the
starter cord about 12" to 18".
During cold starting, you may
need to pull at least three or
four times before the engine
fires.
NOTE: When the choke is
closed, never pull the cord more
than four or five times.
Overpulling may cause flooding.
Also, bear in mind that, when
the engine fires, it only coughs
or sputters, and will not run
on choke.
8. Push the choke button in,
all the way, to open the choke.
(Picture 5)
9. Then pull the starter cord
again. The engine should start
and run. Let the engine warm
up two to three minutes before
using.
Follow these steps whenever you
are starting the engine “cold”, or
when the engine has run dry and
you have just added fuel.
Remember, always use short, brisk
pulls. Don’t give the cord a long,
forceful yank. And, do not let the
cord snap back into the starter
housing.
Page 11
11
Starting a Warm
Engine
1. Push ignition switch to “I”
position.
2. Push choke button in to
the RUN (open) position.
3. If there is no fuel in the
clear return line, push primer
bulb 3-4 times or until fuel is
visible in the line.
4. Pull starter rope using
short pulls, 1/2 to 2/3 of the
rope length.
5. If engine fails to start in 4
pulls, use “First Time” starting
procedure on page 10.
6. With engine running, and
both hands on the handles,
press the throttle lock out
button (Picture 1), then squeeze
the throttle lever gradually to
increase the engine speed and
engage the tines.
NOTE: Once the throttle
lever is squeezed, you can
release the lockout button.
(Picture 2)
NOTE: Step #6 must be
repeated each time your tiller
trigger is released.
How to Stop the
Engine
Simply push the o/I
“stop/start” switch to “o”
(Picture 3). This will stop the
engine instantly. If it should
ever fail to do so, just pull out
the choke button. The engine
will stop at once.
About the Choke
The choke controls the
amount of air drawn into the
engine. Your tiller will run only
if the choke is open — that is, if
the choke is pushed in.
A Special Feature
(with the idle set
properly and the
engine running)
Even when the engine is
running, the tines won’t turn
unless you press the throttle
lock out button and squeeze the
throttle lever on the handlebars.
And, when you release the
throttle lever, the tines will stop.
A Tip for Extending
Your Engine’s Life
After you start the engine, let
your tiller warm up for two to
three minutes before you use it.
Then, before you put your tiller
away, let it idle for a minute to
give the engine a chance to cool
down.
WARNING • DANGER
I
F ENGINE DOES NOT STOP WHEN SWITCH IS PUT IN THE STOP
POSITION, RELEASE THE THROTTLE, ALLOW ENGINE TO IDLE.
PUT THE TILLER DOWN, AND PULL THE CHOKE BUTTON OUT
TO COLD START (CLOSED) POSITION.
CHECK AND RETURN IGNITION SWITCH TO ON POSITION
BEFORE STARTING ENGINE AGAIN.

If you follow the normal
starting procedure, you should
have no problem starting your
tiller. But, just in case you do
have problems, here’s what to do.
Make sure the “o/
I” switch is
on “
I”. You’d be surprised how
many people forget to push the
switch into the “start” position.
If the switch was on “o” when
you pulled the cord, you may
have flooded the engine.
•First, examine the spark plug.
Use the special wrench that
comes with our optional
MANTIS Handy Item Kit (Item
#8444) or a 3/4 inch spark plug
wrench. (Picture 1)
•Remove the cap over the spark
plug.
•Unscrew the spark plug.
(Picture 2)
Starting a Flooded
Engine
1. If the end of the spark plug
is wet, the engine may be
flooded. Make sure the switch
is in the “o” position,
disconnect spark plug wire
and remove plug. Use a paper
towel or a clean rag to dry the
spark plug, then, with the
spark plug out of the engine,
pull the starter cord several
times. Next, replace the spark
plug. Use the wrench to tighten
it and replace the cap. Next, put
the switch in the “
I” position and
pull the choke button out. Pull
the starter cord three or four
times until the engine coughs or
sputters. Open the choke (push
the choke button in) and pull
the cord a few times. The engine
should start and run.
2. If the end of the spark plug
is dry, check to see if the fuel
line is blocked. First loosen the
fuel cap to relieve pressure in the
tank. The fuel line runs from
the fuel tank to the carburetor.
Pull it off at the carburetor end.
Fuel should drip slowly from the
line. Wipe off any excess or
spilled fuel.
If fuel does not drip from the
line, check the line for any bends
or pinches. (Picture 3). Kinks in
the line restrict the flow of fuel
to the engine. Just straighten out
the line. Reconnect. Then follow
the normal starting procedure.
If fuel drips too freely, the line
may be disconnected from the
fuel filter. You’ll find the fuel
filter inside the fuel tank. Just reattach the line to the filter, and
put the filter back in the tank.
Then follow the normal starting
procedure.
Here’s Another Way to
Start your MANTIS
Tiller
If you follow the steps above
and your engine still won’t start,
try this:
1. Push the switch to “
I”.
WARNING
MAKE SURE THE START/STOP
SWITCH IS IN THE
STOP POSITION.
KEEP PLUG WIRE AWAY
FROM ENGINE TO AVOID
UNINTENTIONAL SPARK.
IMPORTANT NOTE:
To avoid possible damage
to the threads, do not try
to remove the plug from a
hot aluminum cylinder
head.

2. Push in the choke button
to open the choke.
3. Press the plastic bubble a
few times.
4. Give the starter cord a few
short, quick pulls. The engine
should start and run.
5. If the engine does not start,
then pull out the choke button
to close the choke. Pull the
starter cord four to five times.
The engine should sputter or
cough.
6. After the engine sputters,
push the choke button in. Then
pull the starter cord. The engine
should start and run.
7. If the engine still does not
start, repeat steps 2 through 6.
8. If the engine still does
not start, call 1-800-366-6268
and ask for Customer Service
or the name of your local
MANTIS dealer.
IMPORTANT NOTE:
Never use starting fluids.
Starting fluids will cause
permanent engine
damage. Using them will
void the warranty.
IMPORTANT NOTE:
Before you use your
MANTIS Tiller, read the
Safety Rules & Warnings
on pages 3-5.
WHAT TO DO JUST IN CASE (continued)
GETTING YOUR TILLER TO YOUR GARDEN
Walk it.
Once your tiller is running,
you can “walk” it to your
garden. Just press the throttle
lock out button and squeeze the
throttle lever gently and let the
tiller “tip-toe” across your yard
on its tines. It won’t hurt your
lawn or driveway.
Carry It.
Make sure the engine is off.
Then use one hand to grasp the
convenient carrying handle. Use
the other hand to hold the
handlebars. (Picture 1) Then lift
your tiller and carry it to your
garden. Since it weighs only 20
pounds, it won’t strain your
muscles or tire you out!
Take It for a Ride.
You can easily transport your
MANTIS Tiller to a friend’s or
relative’s house. Just empty the
fuel tank. (This is crucial.)
Then stow your Tiller in the
trunk of your car or truck. It
fits easily. And you can put it in
and take it our without
straining your back.
WARNING
NEVER CARRY YOUR TILLER
AS THE PERSON IN PICTURE 2
IS DOING. IF YOU DO,
YOU WILL SUFFER
SERIOUS INJURY.

Now You’re Ready to
Use Your MANTIS Tiller.
If you’ve seen other tillers,
your MANTIS Tiller may surprise
you. It tills best when you pull it
backward! You see, when you
pull your MANTIS Tiller
backward, you give extra
resistance to the tines, so they
dig deeper.
(Picture 1)
What’s more when you go
backward, you erase your
footprints. So your soil stays light
and fluffy. With other tillers, by
contrast, you walk right over the
soil you’ve just tilled, packing it
down, so it’s less plantable.
Run Your MANTIS
Tiller like a Vacuum
Cleaner.
Place your Tiller at the head of
the row or area you want to till.
Start it up. Then use an easy
rocking motion. First, pull your
Tiller backward. Then use an
easy rocking motion. Again, pull
your Tiller backward. Then, let it
move forward just a little bit.
Then pull it backward again.
This will help you till deeper.
Keep repeating these steps
until you’ve tilled an entire row.
Start again on the next row. It’s
much like running a vacuum
cleaner! (Picture 2)
You Can Even Control
Depth.
For Deeper Tilling:
Move your Tiller slowly back
and forth, as you would a vacuum
cleaner. Work the same area over
and over until you’ve dug to your
desired depth. (Picture 3)
For Shallow Tilling:
Switch the tines to the
cultivating position. (See page
15 to learn how.) Then move
your Tiller quickly over your
soil surface.
For Big Weeds or Tough Roots:
Let your Tiller rock back and
forth over the tough spot, until
the tines slice through the weed
or root.
Your MANTIS Tiller
Handles Special Tilling
Projects.
Want to turn part of your lawn
into a colorful flower border?
Your MANTIS Tiller makes it
easy! Just run your Tiller back
and forth until the sod begins to
break up. Then continue tilling.
Your Tiller will chop the clumps
of sod until they’re fine. Then, it
will work them into the soil.
Pretty soon, you’ll have a soft,
fresh planting bed.

TILLING/CULTIVATING
How about a family-size
vegetable garden?
Nowadays many gardeners
prefer small gardens —
especially in the suburbs, where
space is at a premium. But, if
you’re fortunate enough to own
a large lot, you can create a
bigger garden — a half acre or
more. Here’s how:
1. First, hire someone with a
tractor or big tiller to break
ground for you. This is a onetime-only investment that’s well
worth the small cost.
2. Then, use your Tiller to
break up any remaining clumps
of soil or sod. Unlike a tractor
or big tiller, your MANTIS Tiller
is a precision tool. It will
pulverize your soil into a
smooth seed bed.
Your MANTIS Tiller
Makes Weeding a
Pleasure!
As a tiller, your MANTIS
Tiller works the soil down to
10” (25.4 cm) deep. But, as a
cultivator, it gently cultivates
the surface, only 2” to 3” (5.09
cm to 7.62 cm) deep.
First, you must change the
tines to the weeding position.
This takes less than a minute.
Then, your MANTIS Tiller’s
sharp “tine teeth” will slice up
those pesky weeds, burying
them as you go along. And,
since the tines in this position
won’t dig too deep, they won’t
hurt your plants’ precious root
systems.
The result? Your Tiller will
cut your weeding time in half,
and turn a tiresome chore into a
pleasure.
How to Switch From
Tilling to Cultivating
Position
1. Make sure your Tiller is
off.
2. Remove the retaining pins
from the tines.
3. Remove the tines from the
axle.
4. Place the right-side tine
onto the left-side axle. Place the
left side tine onto the right-side
axle. The “D” hole should be to
the outside.
5. Here is how to make sure
you’ve installed the tines
properly. Stand behind the Tiller
and hold your hand, palm up,
next to the tines. Do the tine
points curl up, as your fingers
do? If so, they are in the correct
cultivating position.
6. Reinsert the pins.
WARNING • DANGER
IF YOUR TINES GET JAMMED OR ENTANGLED, SHUT OFF THE ENGINE AT ONCE.
REMOVE THE SPARK PLUG WIRE THEN REMOVE THE OBSTRUCTION
WHILE THE ENGINE IS OFF. NEVER TRY TO REMOVE AN OBSTRUCTION
WHILE THE ENGINE IS RUNNING. SERIOUS INJURY CAN RESULT.
! !
Picture 1 Picture 2
Page 16

Now You’re Ready to
Cultivate or Weed.
Guide your Tiller where you
want to weed and start it up.
Pull your Tiller backward
slowly, then let it move forward
a bit, in a gentle rocking
motion. Watch it slice, shred,
and bury those weeds!
Got tough weeds? Lighten
your pressure on the throttle to
slow your Tiller down. Then
work back and forth until your
Tiller chops up the weeds. It’s
easy and effective!
Remember, any tiller will
tangle in tall grass, stringy
vines, or super-big weeds. So, if
you have a “backyard jungle,”
first use a knife, pruner, or
brush cutter to chop up the
overgrowth. If the tines become
tangled anyway, toggle the
switch to the “o” position to
turn the engine off completely
before trying to clear them.
Your Mantis Tiller Will
Weed Between Narrow
Rows!
Your Mantis Tiller is a
precision weeder that easily fits
in tight places. So don’t be
afraid to weed anywhere:
between plants and shrubs; in
corners; against fences; on
raised beds; in wide rows; even
in very narrow rows. Your
Mantis Tiller weeds six* to nine
inches wide. So you can run it
in a tightly planted garden
without damaging your delicate
plants. That’s good news for
suburban gardeners, who often
have to plant rows close
together!
*With optional Planter
Furrower attachment
(Item #6222.)
CULTIVATING
Tilling Position
Tine teeth point in the same
direction as the rotation of the
tine; or toward the front of the
Tiller, away from the operator.
Cultivating Position
Tine teeth point in the
opposite direction as the
rotation of the tine. Tines point
toward the back of the tiller, or
toward the operator.

MAINTENANCE
Check the Air Filter Often
A wet or dirty air filter can
affect the way your engine starts,
performs, and wears. So, it’s a
good idea to check your air filter
once a month.
If you work in dusty soil, or if
you want to be on the safe side
— then check your filter more
often (for instance, before each
use). But be sure to replace it at
least once a year, in the spring or
fall. Clean or change it as
needed. It is recommended to
change the air filter yearly.
How to Check, Clean and
Change the Air Filter
1. Loosen the wing nut on the
side of the air-cleaner cover. (See
Picture 1, or look up Key #1 in
Air Cleaner Parts Assembly on
page 28.)
2. Take off the cover. Make
sure to clear the choke button.
(Picture 2)
3. The air filter is the pad
on the inside of the air-cleaner
cover. Check whether it is
soiled or moist.
4. If the air filter needs
cleaning or no longer fits
properly, remove it. Just lift an
edge carefully and “peel” it out.
(Picture 3)
5. Use a brush to remove
debris from the pad.
6. If the air filter is so dirty
that it won’t come clean, you
must replace it or severe engine
damage will occur. Order a new
one directly from your local
Authorized MANTIS Dealer.
7. Insert your clean filter
inside the air-cleaner cover.
IMPORTANT! Make sure
filter is “seated” properly
in the cover. The filter
must fit snugly inside the
rim that holds the filter in
place.
Installing the filter incorrectly
will cause engine damage and
void the warranty. Fit the cover
back over the air cleaner. (Again,
make sure to clear the choke
button.)
8. Tighten the wing nut to
secure the cover.
Note:
Please check the lip
on the Air Cleaner
Cover. If the lip is
chipped or cracked,
it should be
replaced. This will
prevent dirt from
being ingested
through the
carburetor into the
inside of the engine.

How to Check the Grease
Level Inside the
Worm Gear Housing
When we built your MANTIS Tiller,
we lubricated the worm gear housing
thoroughly.
It is imperative that you inspect the
grease level once a year. Simply
remove the cover plate on the worm
gear housing. (Picture 1) Then check
to make sure the grease comes almost
to the top of the housing. If it doesn’t,
add lithium #0 grease (Item M9985.)
This is the only way to add grease to
the worm gear housing. (Picture 2) To
purchase MANTIS grease, contact
your local authorized MANTIS dealer.
Please do not overfill. Too much
grease can create pressure, which
could cause seals to fail or the clutch
to slip.
Fuel Filter Replacement:
Fuel filter to be changed at the end of
every season.
Clear Blockages From the
Fuel Line & Filter:
After you’ve used your Tiller for a
few seasons, check for blockages in
the fuel tank and fuel filter. Such
blockages can keep your Tiller from
starting.
Clear any blockages you see in the
tank, fuel filter, or fuel line.
Remember: The fuel filter is located
inside the tank. (See Picture 3) Then
use the normal starting procedure to
start your Tiller.

What to Do if Your
Engine Idles Too High
What if your engine runs too
fast … or if the tines turn the
instant you start the Tiller? You
may need to adjust the idle
screw (Key #19 under
Carburetor on page 28) by itself
right below the H and L screws.
Gently turn it counterclockwise. You’ll know you’ve
adjusted it correctly when the
axles do not turn at low idle.
What to Do if Your
Engine Runs “Rough”
If your engine runs “rough”
or stalls, you may need to adjust
the carburetor and idle screws.
If you remove the air-cleaner
cover, you’ll see the two
carburetor, adjustment screws
next to the choke button.
(Picture 1)
The “RED” screw is the
HIGH-speed adjustment…The
“WHITE” screw is the low
speed adjustment.
First, remove the tines from
the axle. Then start engine. Let
it run for two to three minutes.
“FLASH” the choke several
times during the warm-up to
clear any air from the Fuel
system.
Then stop the engine after it
reaches operating temperature.
Now, turn the RED, highspeed screw counter-clockwise
all the way to stop…Then turn
the WHITE, low speed screw
halfway between the counterclockwise and clockwise stop
positions.
Now restart the engine to
finish the carburetor
adjustment.
Run the engine at full speed
two or three seconds to clear
out any excess fuel. Then return
to idle.
Now, accelerate the engine to
full throttle several times to
check for a smooth transition
from idle to high speed.
If the engine hesitates turn
the WHITE, low-speed screw
counter-clockwise one-eighth of
a turn. Then accelerate the
engine.
Repeat the adjustment until
you get a smooth transition to
high speed.

1. Take out the spark plug.
2. Remove the red cylinder
cover, (Key #32) which is held
on by 1 phillips-head screw,
(Key #33) and 1 hex-head
screw, (Key #34) which you
will need an allen wrench
to remove.
3. You will see the metal
exhaust guide, held on by 3
more phillips-head screws.
(Key #26) Remove the exhaust
guide.
4. Behind the
exhaust guide
(Key #25) will be the muffler
gasket (Key #24) and muffler
screen (Key #23). The screen
sits under the gasket.
5. If the screen (Key #23) is
clogged with deposits, it needs
to be cleaned. Use carburetor
cleaner, and any brush that is
not metal. Brush the screen
until you are able to see
through it.
6. If the screen remains
plugged after attempts at
cleaning, it must be replaced.

How to Reseat the
Flange
At some point, you may find
that the tines won’t turn when
you press the throttle. This
may mean the engine isn’t
sitting all the way down on the
worm gear housing.
Perhaps you’ve been using
your Tiller for several years.
Or perhaps you’ve removed
the engine for use with our
hedge trimmer attachment,
then replaced it. In either case,
the flange bolt (Key #38, page
29) may have come loose and
lifted the engine up.
If this happened you’ll
notice a gap between the
bottom of the engine clutch
case (Key #39, page 29) and
the top of the worm gear
housing. (Picture 1)
To fix this, loosen the flange
bolt. Take the engine off the
worm gear housing. Notice
the hex head on top of the
drive shaft (Key #9, Page 27).
Inside the clutch case, you’ll
find the clutch drum (Key
#31, Page 29). Make sure the
hex head lines up with the
clutch drum inside the clutch
case.
Then put the engine back
on the worm gear housing.
Make sure the plastic carrying
handle is not under the fuel
tank.
If you’ve followed these steps
properly, there will be no gap
between the clutch case and
the worm gear housing.
(Picture 2) Make sure you
tighten the flange bolt!
Picture 1 … Note how the
engine doesn’t sit all the way
down on the transmission.

STORAGE
Each fall — or before you
store your Mantis Tiller for
any long period — be sure to
take these measures:
1. Do not store your Tiller
with fuel still in it. Even under
ideal conditions, stored fuel
containing ethanol or MTBE
can start to go stale in 30 days.
And, since stale fuel has a
high gum content, it can clog
the carburetor, this, in turn,
will restrict fuel flow. So,
when you’re ready to store
your Tiller, or will not be
using it for more than 2
weeks, drain the fuel tank
completely. (Picture 2)
2. Next, restart the engine
to make sure no fuel is left in
the carburetor. Then run the
engine until it stops. This will
prevent gum deposits, forming
inside of the carburetor and
possible engine damage.
3. Disconnect spark plug
wire and remove the spark
plug. (Use the wrench that
comes in our optional Handy
item Kit, Item #8444. Or use a
19mm or 3/4” spark-plug
wrench.) Pour about a
teaspoon of clean, air-cooled,
two-cycle oil through the
spark-plug hole into the
combustion chamber. (Picture 3)
Leaving the spark plug out
slowly pull the starter cord
two or three times to coat the
inside of the cylinder wall.
4. Replace the spark plug, and,
if necessary, clean it. If you
need to replace it, buy a
NGK-BPM8Y. A replacement
spark plug is included in the
optional
Handy Item Kit item
# 8444
.
5. Install the spark plug, but
leave the spark plug wire
disconnected.
6. Clean the air filter as
described on Page 17.
7. Clean dirt, grass, and
other materials from the entire
machine.
8. Wipe the tines with oil or
spray them with WD-40, to
prevent rusting.
9. Oil the throttle cable and
all visible moving parts. (Do
not remove the engine cover.)
10. Replace the fuel filter.

11. Check the grease level in the
worm gear housing, as described
on page 18.
12. Order new parts to
replace any that are badly
worn or broken. Just call
1-800-366-6268 and ask for a local
authorized Mantis dealer.
13. Store your Tiller, in an
upright position, in a clean, dry
place. You can store with the
handles in an extended position or
folded down. (Picture #1,
preceding page)
14. To fold the handles, follow
these easy steps: Loosen the
handle knobs (#40), fold the
handles forward (see picture #1,
inset, preceding page). Tighten
knob securely. Your handles are
now folded and ready to store in a
smaller area.
15. Do you have fuel left over
from last season? Dispose of it
properly. Buy fresh oil and gasoline
next season.
How to Prepare Your
MANTIS Tiller for
Restarting
Unfold the handles into an upright or extended position. Tighten
the two handle knobs (#40)
In the Spring, when you take your
Tiller out of storage, remove the
spark plug. Pull the starter cord
three or four times to clean oil
from the combustion chamber.
(Picture 1) Wipe oil from the
spark plug. Place the spark plug
back into the cylinder. Re-connect
the spark plug wire back on the
spark plug. Then follow the steps
on pages 9 & 10 to refuel and
restart your Tiller.
Again, Check the
Carburetor.
If your Tiller won’t restart in the
Spring — or if it lacks its usual
power — the carburetor may need
attention. Follow the steps on
page 19 for adjusting the H and L
screws. (Picture 2)
Check the Spark Plug
Too.
If your Tiller won’t restart, or if
it lacks full power, the spark plug
may be at fault. Check to see if the
plug is fouled with oily black
deposits. Clean or replace it if it is.
(Picture 3)
Also, check whether the center
electrode is rounded at the end,
or if the ground electrode is worn.
If either is the case, you should
replace it with a NGK-BPM8Y
spark plug. Use a 19mm or a 3/4”
spark-plug wrench to install it.
Adjust the plug gap .024 - .028 in.
(
0.6 to 0.7 mm)
Caution: Do not over
tighten the plug. The correct
torque is 18 to 22 ft.-lbs.
(24-30 n.m)
IMPORTANT NOTE:
To avoid possible damage
to the threads, do not try to
remove the plug from a hot
aluminum cylinder head.
Warning
Always make sure the handle
knobs are secure before
starting your Mantis Tiller.

Your MANTIS Tiller has been
designed and built to accept a
wide range of MANTIS Tiller
Attachments to increase its
usefulness in your lawn and
garden. And, all MANTIS Tiller
Attachments have been
designed for quick and easy
attachment to the Tiller or
Engine.
The Border Edger
(Item #3222)
The most popular
attachment, the Border Edger
can be used to cut clean, neat
edges along walkways, or
around trees, shrubs, and
garden beds.
The Border Edger has two
parts: a wheel and a hardened
steel blade, with pointed tines.
How to Install the
Border Edger
The following instructions
refer to “right” and “left” axles.
Assume that you’re standing
behind your Tiller, as you
would for tilling and
cultivating.
Some areas of your yard may
harbor roots and other
underground obstructions. In
places like this you’ll want to
edge your borders shallowly (1”
to 2” deep). Here’s how to
install the Border Edger for
shallow edging:
1. First remove your
tilling/cultivating tines.
2. Then slide the edger’s
wheel onto the right axle.
3. Now slide the Edger blade
onto the left axle. The blade’s
angled face should hit the
ground when you spin the blade
forward.
4. Insert retaining pins on
both left and right axles.
Around walkways and garden
beds, you’ll want to edge more
deeply (3” to 4” deep). Here’s
how to install the Border Edger
for that purpose:
1. Remove the
tilling/cultivating tines.
2. Slide the Edger’s blade onto
the right axle. The blade’s
pointed face should hit the
ground when you spin the blade
forward.
3. Slide the wheel onto the
left axle.
4. Insert retaining pins on

How to Use the
Border Edger
1. Position your MANTIS
Tiller so that the Edger blade is
right along the garden edge and
the wheel is outside (on the
lawn, on the sidewalk,
wherever). (Picture 1)
2. Start your Tiller and pull
your MANTIS backward along
the garden edge. (Picture 2)
The Border Edger Can
Handle Special
Projects!
1. Install the Edger for deep
edging, as directed above. Then
use it to cut sod strips.
2. Edge and weed at the same
time! Just attach the Edger
blade on one axle and a Tiller
tine on the other axle, “Mix and
match” blades; don’t be afraid to
experiment.
IMPORTANT NOTE:
If you do a lot of edging,
you’ll appreciate the
MANTIS Wheel Set
(Item#9222.) It gives you
added stability, for even
easier handling.
To order the wheel Set, or
any MANTIS Attachment,
contact your local authorized
MANTIS dealer.
