WARNING • DANGER
Tiller/Cultivator
OWNER’S MANUAL
WELCOME TO THE WORLD
OF MANTIS GARDENING!
Here’s your new MANTIS Tiller . . .
the lightweight wonder that’s
“Changing the way we garden.”
Unlike big tillers, your MANTIS Tiller
weighs only 9 kg. So it lifts easily,
handles smoothly, tills and weeds
precisely. And, unlike other small
tillers, it features serpentine tines that
churn soil to 25 cm 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 authorised Mantis dealer.

WARNING • DANGER
IMPROPER ASSEMBLY OF THIS TILLER
CAN RESULT IN SERIOUS INJURY.
MAKE SURE TO FOLLOW ALL
INSTRUCTIONS CAREFULLY.
IF YOU HAVE ANY QUESTIONS
CONTACT YOUR AUTHORISED
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 11 mm (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.

HOW TO ASSEMBLE
LOWER HANDLES
To identify part numbers, see
pages 6 and 27.
1. Use the protective
cardboard sleeve to stabilize
your tiller. Stand the engine
assembly (No. 21) up.
2. Lay the handle parts within
easy reach. You’ll need one of the
handle clamps (No. 51) and one of
the lower handles (No. 6). Note
that the lower handles have a short
leg on one end. (Picture 1)
3. Fit the handle clamp along
the outside of the short leg. Line
up the holes on the clamp and the
leg.
4. Choose one of the two 3-inch
(7.62 cm) bolts (No. 49). Slide it
through the first set of holes —
near the elbow where the lower
handle curves. (Picture 2)
5. Now slide the other lower
handle onto the 3-inch (7.62 cm)
bolt. (Picture 3.) Fit the other
clamp onto this other handle’s
short leg. Add a nut and tighten
finger tight.
6. Locate the worm gear
housing. It starts just above — and
extends down through — the
tiller’s red fender guard. You’ll
notice that there’s a recessed
channel on either side of the
housing’s top. (Picture 4.)
7. Take the lower handles that
you’ve just put together. Slide
them into the two recessed
channels.
! Make sure you insert them
from the rear of the tiller (petrol
tank faces the operator) . . . so that
the bolt fits along the back of the
housing. (Picture 1 and 2, Page 8)
8. Slide the second 3-inch (7.62
cm) bolt through the second set of
holes in the short legs. Add a nut
and tighten finger tight.
NOTE: THE LOCK NUTS ARE STAMPED. FINGER TIGHT IS
APPROXIMATELY 1/2 TO 1-1/2 TURNS.

HOW TO ASSEMBLE
UPPER HANDLES &
PLASTIC CARRYING
HANDLE.
1. Lightly squeeze the lower
handles (No. 6) toward one
another so that they line up
with the two smaller holes on
the carrying handle (No. 42).
Then slide the carrying handle
over and down the lower
handles. It will rest about 10-15
cm above the engine. (Picture 1)
2. Gently pull the lower
handles out to their original
position.
3. Attach the upper handle
assembly (No. 5A) – the handle
with the throttle cable and
ground wire – onto either
handle, and secure
with the handle knob (No. 53).
You can attach this upper handle
to whichever lower handle you
prefer, depending on which
hand you’d rather use to
squeeze the throttle. (Picture
No. 2) Note: If throttle handle is
mounted on the left, it will not
fold down as completely as
when mounted on the right. Be
sure you have proper throttle
movements and that the
throttle cable is not wrapped
or twisted around the handle
bar. Squeeze trigger and let go.
The triangle must click in both
directions. If there is any doubt,
remove air filter and visually
check that the throttle triangle
hits both the idle screw and the
full open stop. THIS MUST BE
DONE BEFORE STARTING
THE ENGINE.
4. Follow the same steps to
install the other upper handle
onto the other lower handle.
(Picture 3)
5. Use the clip (No. 13) to
secure the throttle cable and
wire in place on the lower
handle. (Picture 4)
6. Now install the handle
brace. Line it up with the holes
on the upper handles. Then
insert a cap screw and a lock nut
on either side (Picture 5)
7. Use a wrench to tighten cap
screws and lock nuts.
8. Now use wrench to tighten
all nuts and bolts firmly and
securely.
IMPORTANT NOTE:
Make sure you have
installed the handles
properly. When you stand
behind your tiller, holding
the handles, you should
face the petrol tank.
! WARNING: Improper throttle installation can cause
tines to rotate unexpectedly .

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.
Mixing Fuel
Your MANTIS Tiller is powered by
a commercial two stroke, air cooled
engine which requires a fuel mixture
of petrol and lubricating oil.
Use a mixture of 50 parts
unleaded regular petrol and 1 part
two-stroke MANTIS oil (50:1.) Use branded 89 octane (R+M+2)
unleaded petrol or ethanol (maximum 10% ethyl alcohol, or 15%
MTBE, no methyl alcohol.)
!
WARNING • DANGER
!
FUEL IS EXTREMELY FLAMMABLE. HANDLE IT WITH
CARE. KEEP AWAY FROM IGNITION SOURCES. DO NOT
SMOKE WHILE FUELLING YOUR EQUIPMENT.
Your Mantis Tiller comes with
a free pre-measured bottle of
two-cycle engine oil. Here’s how
to mix the oil with the petrol:
1. Pour 1.9 l (1/2 gallon) of
the petrol into a safe container.
Do not mix the fuel and oil in
the engine fuel tank.
2. Add 77 ml (2.6 ounces) of
two-cycle engine oil to the petrol
and mix. Then add the other 1.9
litres (1/2 gallon) of the petrol.
3. Screw the cap onto the
petrol can. Then swirl the can to
blend the oil and petrol.
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 petrol 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 petrol
only, use proper fuel mixture.
Need more pre-measured
engine oil? Contact your local
authorised Mantis dealer.
Remember …
•Always mix two-cycle oil with
petrol before fuelling your tiller.
Never, ever run your tiller on
petrol alone. This will ruin your
engine and void all warranties.
•Always use a clean petrol can
and always use unleaded petrol.
•Never try to mix the oil and
petrol in the engine fuel tank.
•Always mix oil and petrol in
the proper proportions: 3.78
litres (1 gallon) of unleaded
petrol to 77 ml (2.6 ounces) of
two-cycle engine oil.
IMPORTANT NOTE:
Do not use old or stale
oil/petrol mixture. Always
use the proper oil/petrol
mixture. If you do not,
your engine will suffer
rapid, permanent damage.
And you will void the
engine warranty.

STARTING
! WARNING !
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 start/stop switch
into the “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
lever 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 30 to 45 cm.
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.
DO NOT SQUEEZE THE
THROTTLE TRIGGER
WHEN STARTING.
MAINTAIN PROPER IDLE

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

WHAT TO DO JUST IN CASE
Picture 1
Picture 2
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 start/stop
switch is on “start.” You’d be
surprised how many people
forget to push the switch into the
“start” position.
If the switch was on “stop”
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
No. 1422) or a spark plug
wrench. (Picture 1)
•Remove the cap over the spark
plug.
IMPORTANT NOTE:
To avoid possible damage
to the threads, do not try
to remove the plug from a
hot aluminium cylinder
head.
•Unscrew the spark plug.
(Picture 2)
! WARNING !
MAKE SURE THE START/STOP
SWITCH IS IN THE STOP
POSITION.
KEEP PLUG WIRE AWAY FROM
ENGINE TO AVOID
UNINTENTIONAL SPARK.
Picture 3
Starting a flooded
engine
1. If the end of the spark plug
is wet, the engine may be
flooded. Make sure the switch
12
is in the stop 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.
Shake the fuel out of the inside
of the plug and air dry. Next,
replace the spark plug. Use the
wrench to tighten it and replace
the cap. Next, put the switch in
the start 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. The fuel line
runs from the fuel tank to the
carburettor. Pull it off at the
carburettor 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 “start.”
WHAT TO DO JUST IN CASE (continued)
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 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.
GETTING YOUR TILLER TO YOUR GARDEN
Walk it.
Once your tiller is running,
you can “walk” it to your
garden. Just press the throttle
lever gently and let the tiller
“tip-toe” across your garden on
its tines. It won’t hurt your lawn
or driveway. (Picture 1)
Carry It.
Make sure the engine is off.
Then use one hand to grasp the
Picture 1
convenient carrying handle. Use
the other hand to hold the
handlebars. (Picture 2) Then lift
your tiller and carry it to your
garden. Since it weighs only 9
kg, it won’t strain your muscles
or tire you out!

Now you’re ready to use
your MANTIS Tiller.
You can even control
depth.
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.
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.
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)
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.

WARNING • DANGER
!
IF YOUR TINES GET JAMMED OR ENTANGLED, SHUT OFF THE ENGINE AT ONCE.
REMOVE THE OBSTRUCTION WHILE THE ENGINE IS OFF.
NEVER TRY TO REMOVE AN OBSTRUCTION WHILE THE ENGINE IS RUNNING.
SERIOUS INJURY CAN RESULT.
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.
Picture 1
Picture 2
Your MANTIS Tiller
makes weeding a
pleasure!
How to switch from
tilling to cultivating
position
As a tiller, your MANTIS
Tiller works the soil down to
10” (25.4 cm) deep. But, as a
tiller, it gently cultivates the
surface, only 2” to 3” (5.09 cm
to 7.62 cm) deep.
First, you must switch 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.
1. Make sure your tiller of 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.
15
CULTIVATING
Now you’re ready to
cultivate or weed.
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.
16
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 “backgarden jungle,”
first use a knife, pruner, or
brush cutter to chop up the
overgrowth. If the tines become
tangled anyway, turn the
engine off completely before
trying to clear them.
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
autumn. Clean or change it as
needed. It is recommended to
change the air filter yearly.
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
authorised 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.
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 No. 9
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 white
pad on the inside of the aircleaner cover. Check whether it
is soiled or moist.
Picture 1
Picture 2
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
carburettor into the
inside of the engine.
Picture 3
17
MAINTENANCE (continued)
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 authorised MANTIS dealer.
Please do not overfill. Too much
grease can create pressure, which
could cause seals to fail or the clutch
to slip.
Picture 1
Picture 2
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.

Picture 3
MAINTENANCE (continued)
! WARNING•DANGER !
REMOVE TINES BEFORE
STARTING ENGINE AND
MAKING ADJUSTMENTS
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 No. 25 under
Carburettor 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.
If you continue to have idle
problems, you may need to
adjust the throttle cable.
First, locate the metal triangle
at the end of the throttle cable.
(Picture 1) The idle screw must
touch this triangle. But, if the
throttle cable’s too tight, you’ll
see a gap between the idle screw
and the triangle.
To fix this, loosen the top nut
that holds the throttle cable in
place. (Picture 2) (Use an
Picture 1
11mm wrench or an adjustable
wrench.) Then, slide the cable
down until you close the gap
between the triangle and the
idle screw. (Picture 1) Now,
tighten the bottom nut that
holds the throttle cable.
Locate the metal “button” on
the triangle. This is the swivel.
The large end of the throttle
cable must be inside the slot in
this swivel. (Picture 3)
What to do if your
engine runs “rough”
When we built your Mantis
Tiller, we adjusted the
carburettor for top performance.
But from time to time, it may
need readjusting. If your engine
runs “rough” or stalls, the
carburettor may be the cause.
1. Make sure the engine is
shut off.
2. To identify the
carburettor, look up parts
assembly on page 29. Then find
the identical part on your tiller.
3. If you remove the air
cleaner cover, you’ll see two
letters stamped on the
carburettor body: “H” (on the
Picture 2
left) and “L” (on the right).
They stand for “High-speed
needle valve” and “Low-speed
needle valve,” respectively (Key
No. 16 & 15 under Carburettor
on page 29.) Lightly turn each
screw clockwise until it’s
completely closed. (Picture 2)
4. Then, turn each screw
counterclockwise very slowly one full turn plus one-quarter
turn, more or less.
Every season, you may need
to readjust the H and L screws
to ensure smooth running. You
don’t need to take off the aircleaner cover. Just remove the
tines and start the engine.
While the engine is at low idle,
slowly turn the L screw
counterclockwise, until the
engine sputters. Then slowly
turn it clockwise until the
engine sounds smooth.
Next, repeat the procedure
for the H screw. but this time,
squeeze the throttle and run the
engine at high speed. This will
make your tiller run smoothly.
Picture 3
19
MAINTENANCE (continued)
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 No. 22, 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 flange
(Key No. 24, 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 No. 22, Page
27). Inside the flange housing,
you’ll find the clutch drum
(Key No. 25, Page 29). Make
sure the hex head lines up
with the clutch drum inside
the flange housing.
Then put the engine back
on the worm gear housing.
Make sure the plastic carrying
handle is not under the fuel
tank.
Picture 1 … Note how the
engine doesn’t sit all the way
down on the transmission.
If you’ve followed these steps
properly, there will be no gap
between the engine flange and
the worm gear housing.
(Picture 2) Make sure you
tighten the flange bolt!
Picture 2 … Note how the
engine sits all the way down on
the transmission.
Cleaning the Exhaust
Screen
2. Remove the red cylinder
cover, (Key No. 19) which is
held on by 2 phillips-head
screws. (Key No. 18)
4. Behind the fixture
(Key No. 25) will be
the exhaust lid (Key
No. 24) and exhaust lid
gasket (Key No. 23).
The screen sits in the
gasket.
3. You will see the metal
screen fixture, held on by 3
more phillips-head screws.
(Key No. 26) Remove the
fixture.
5. If the screen (Key No.
22) is clogged with deposits, it
needs to be cleaned. Use
carburettor cleaner, and any
brush that is not metal.
1. Take out the spark plug.
20
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.
STORAGE
!
!
WARNING•DANGER
DO NOT STORE IN AN AREA
WHERE FUEL FUMES MAY
ACCUMULATE AND REACH A
FLAME OR SPARK.
Each autumn — 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 carburettor, 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 carburettor. Then run the
engine until it stops. This will
prevent gum deposits, forming
inside of the carburettor 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 No. 1422. Or
use a 19mm or 3/4” sparkplug wrench.) Pour about a
teaspoon of clean, air-cooled,
two-cycle oil through the
spark-plug hole into the
combustion chamber. (Picture 3)
Slowly pull the starter cord
two or three times to coat the
inside of the cylinder wall.
Picture 1
4. Inspect the spark plug, and,
if necessary, clean it. If you
need to replace it, buy a
NGK-BPMR-7A. A
replacement spark plug is
included in the optional
Handy Item Kit item No. 1422.
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.)
Picture 2
Picture 3
21
STORAGE (continued)
10. Check the grease level in the
worm gear housing, as described
on page 18.
11. Order new parts to replace
any that are badly worn or broken.
Just call your local authorised
Mantis dealer.
12. 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)
13. To fold the handles, follow
these easy steps: Loosen the
handle knobs (No. 53), fold the
handles forward (see picture 1,
inset, preceding page). Tighten
knobe securely. Your handles are
now folded and ready to store in a
smaller area.
14. Do you have fuel left over
from last season? Dispose of it
properly. Buy fresh oil and petrol
next season.
How to prepare your
MANTIS Tiller for
restarting
Unfold the handles into an upright or extended position. Tighten
the two handle knobs (No. 53)
!Warning!
Always make sure the handle
knobs are secure before starting
your Mantis Tiller.
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
carburettor.
If your Tiller won’t restart in the
Spring — or if it lacks its usual
power — the carburettor may need
attention. Follow the steps on
page 19 for adjusting the H and L
screws. (Picture 2)
Picture 1
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-BPMR-7A
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)
Picture 2
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
aluminium cylinder head.

USING THE BORDER EDGER ATTACHMENT
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 No. 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 garden
may harbor roots and other
underground obstructions. In
places like this you’ll want to
edge your borders shallowly
2.54 to 5 cm deep (1” to 2”).
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 7.5 to 10 cm deep (3” to
4”). 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
both sides.
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
No. 9222.) It gives you
added stability, for even
easier handling.
To order the wheel Set, or
any MANTIS attachment,
contact your local authorised
MANTIS dealer.
