5.1 How does my MissionNANOTM know what to mow?
Congratulations on your new purchase of the MissionNANO
TM
and welcome to the care-free life of automatic
mowing. In the following, we would like to help you better understand how your MissionNANO
TM
thinks.
5. Understanding Your MissionNANOTM
A

11
EN
5.2 How does my MissionNANOTM know where to go?
Your MissionNANO™ is capable of doing things on its own. MissionNANO™ knows when it needs to go to
its charging base to charge, can sense when it is raining, can stop itself if it senses a problem, and knows to
stop, draw back, and turn around when it bumps into something blocking its path. MissionNANO™ will also
automatically stop its blade turning disc from rotating if it is lifted off the ground to prevent an accident.
A. Finding the Charging Base
When your MissionNANO™ needs to recharge, it will stop mowing and follow the boundary wire in an anti-
clockwise direction back to its charging base. MissionNANO™ is pre-programmed to mow the grass near the
boundary wire once a week. By default, MissionNANO™ will mow near the boundary wire at a random time
during the next week after it is powered on.
If you don’t want to enable boundary cut, deactivate it via your smartphone.
B. Rain sensors
MissionNANO™ is equipped with a rain sensor which
detects rain and tells the MissionNANO™ to stop mowing
and follow the boundary wire back to its charging base
(See Fig. B).
MissionNANO™ will resume mowing after passing the
delay time, the default delay time is 180mins. Delay time
setting can be changed via MissionNANO™ APP.
When the rain sensors are wet, MissionNANO™ returns
to its charging base. The error indication light will flash
blue four times per cycle. When the rain sensors dry,
MissionNANO™ will begin the delay time countdown or return to mowing (depending on the saved settings).
If you want to exit from the rain delay, dry the sensor area, and perform a power cycle by operating the main
switch. After the power cycle has been performed you can see that the blue LED is not flashing and so you
can operate again.
NOTE: If the delay time is set to 0, MissionNANO™ will continue mowing.
C. Sensing the boundary wire
MissionNANO™ always obeys the border set by the
boundary wire and uses sensors at its front to detect it.
(See Fig. C)
D. Starting and stopping while mowing (See Fig. D, E1, E2)
If you would like MissionNANO™ to stop mowing, simply press the STOP button on top of the mower. To start
mowing, turn the main switch to “I” (on). Wait until the battery indication light stays green. (If MissionNANO™
has low battery capacity, the battery indication light will stay red.) Press , then press .
If MissionNANO™ senses something is wrong, the error indication light will indicate the fault message. For
information on these messages, refer to the Error Messages. MissionNANO™ will turn off if it does not receive
any input from the user within 20 mins.
To resume:
• Turn the main switch to “O”(off)
• Correct the problem (refer to Error Messages)
• Turn the main switch to “I”(on). Wait until the battery indication light stays green. (If MissionNANO™ has low
battery capacity, the battery indication light will stay red.)
• Press , then press
• Now the MissionNANO™ will begin to mow!

EN
5.3 Cut to edge
Off-centered blade turning disc design provides a clean cut with narrowest distance to the boundary or
wall. It helps minimize the amount and frequency of manual trimming along the boundary. Additionally,
MissionNANO™ is designed with a protective cover underneath that prevents objects from touching the
turning blades and/or injury. (See Fig. F)
5.4 Working time
MissionNANOTM's default daily working schedule includes 4 hours of working time (mowing and charging
included), and 20 hours on standby on the charging base. See chart below. The working schedule can be
changed using the mobile app. To download the app, please refer to section APP. The working schedule can
be re-set by removing and re-installing the battery. Please refer to Replacing the Battery.

Tall grass working schedule
For the first mowing when the grass grows very tall after
winter or a long holiday, you can change it to tall grass
mowing mode by keep pressing button for 5
seconds until a beep sound is heard. Press then
to start mowing. MissionNANO™ will resume to
previous start time and the default working duration in the
following days.
Change default start time
The default start time of 9:00 can be changed to anytime
by keep pressing both and buttons at
the same time for 3 seconds until a beep sound is heard.
For example, keep pressing both and
buttons at 14:05, and your MissionNANO™ will be
mowing from 14:05 to 18:05.
NOTE: If your MissionNANO™ is shut off, it will resume to
default working duration and the start time will resume to
previous setting when the machine is re-started.
NOTE: When you replace the battery, the working
duration will resume to default working duration and the start time is set to the moment when the battery re-
connected.
5.5 How efficiently will my MissionNANO™ mow the grass?
Mowing times are different for every lawn depending on the factors mentioned below. Gradually adjust the time
you allow MissionNANO™ to mow each day until you find the most suitable setting.
Your MissionNANO™ is capable of mowing areas of different sizes, although this depends on various factors,
such as:
• Species of grass in your lawn and its growth rate
• Sharpness of the cutting blades
• Humidity
• Surrounding temperature
• Amount of obstacles in your Lawn
Unlike most other mowers, MissionNANO™ uses a side charging system, which is able to cut the much
surrounding grass as possible. The holes on the bottom of the charging base allow the grass to grow through
the base to help disguise it and create an elegant appearance.
MissionNANO™’s cutting height can be adjusted between
3cm-6cm. Before starting your MissionNANO™ for the
first time, you should cut the grass to the height no more
than 9 cm. Then, set the cutting height to its maximum
setting, 6cm. (See Fig. G)
Your MissionNANO™ will cut its best in dry weather. Wet
grass can build up on the blade turning disc and within
the motor, and can also cause loose traction and slippage
while working.
Your MissionNANO™ is afraid of lightning storms. In case
of a lightning storm, protect MissionNANO™ by unplugging the charging base, disconnecting the boundary
wire, and making sure MissionNANO™ is not allowed to charge.
Your MissionNANO™ loves mowing grass and requires the cutting blades to be kept in good condition to
cut at its best. MissionNANO™ can do most things by itself, but will sometimes need your help to prevent
damage to itself.
• Never let MissionNANO™ travel over gravel.

• Remove or prevent access to obstacles that MissionNANO™ could accidentally climb on and damage its
blade turning disc.
• Remove all debris and foreign objects from your lawn.
6. App
Your MissionNANO™ is able to connect with smartphone. Using MissionNANO™ App for your smartphone,
you can change your MissionNANO™'s general settings, and view the machine's status and error messages.
To connect smartphone to your MissionNANO™:
Step 1: To download the MissionNANO™ App, use your smartphone to scan the QR code below or download it
from Playstore (Google-Android), AppleStore (Apple-iOS) or our website www.kress-robotik.com.
Step 2: Enter the MissionNANO™ APP, and then follow the instructions to connect to your Wi-Fi.
*The Serial No. can be found at the rear of MissionNANO™ as shown in Fig. H.
NOTE:
1. If your Wi-Fi information changes, MissionNANO™ needs to be re-set according to Step 1 to 2.
2. When MissionNANO™ is located in an area with low or no Wi-Fi signal, instructions sent from the mobile
App may not be executed immediately. MissionNANO™ will receive instructions when it returns to an area with
good Wi-Fi signal.
3. For strong Wi-Fi signal to ensure stable connection, it is recommended to install Wi-Fi extenders to cover
areas with weak or no Wi-Fi signal.
7. Boundary Wire Basics
7.1 Pegging the Boundary Wire
Use the boundary wire distance gauge to set the correct distance between the wire and the border of your
lawn (more than 26cm*).
* This is the recommended distance. The provided
distance gauge ensures proper installation.
If your neighbor also uses a MissionNANO™, keep a
spacing of at least 1 metre between your boundary wire
and your neighbor’s.
The boundary wire must outline the intended mowing area
exactly. Your MissionNANO™ will become confused by
extra bends or coils of boundary wire that are not part of
its mowing area (See Fig. I). If there is excess boundary
wire after the mowing area has been outlined, cut it off
Only suitable for
iOS 11.0 or higher
H

15
EN
and store this additional wire in a separate location. It is important to leave the necessary length where it
connects to the charging base so it can be connected and still remain buried.
7.2 Burying the Boundary Wire
If you are planning to bury the boundary wire, it is recommended to first peg it down. This allows you to easily
change the layout if necessary before burying the wire. When the boundary wire installation is complete, have
MissionNANO™ follow and check the path by pressing and . This will allow MissionNANO™ to
adjust to its new environment.
While observing MissionNANO™ you can easily make alterations to the boundary wire to ensure the
MissionNANO™'s trouble-free tracking when locating the charging station. Confirm that MissionNANO™
docks in the charging station successfully, and bury the wire if desired.
7.3 Joining the boundary wire
If you want to extend and splice the boundary wire, use a connector. The connector is waterproof and
provides optimal connection.
Insert both wire ends in any two of the three holes of the connector. Insert the wires fully until both wire ends
are visible on the other side of the connector. (See Fig. J1) Press the connector together by using a pair of
pliers. (See Fig. J2, J3)
WARNING: It is not recommended to simply splice the boundary wire with insulating tape or use a screw
terminal block for connection. A broken circuit may occur after a period of time as soil moisture can oxidize
the wire.

9. Maintenance
Your MissionNANO™ works hard and needs to be cleaned and checked from time to time. Some parts will
require replacement as they become worn. Never use your MissionNANO™ with defective main switch.
Switch off the machine before carrying out any service or maintenance.
Here's how to take care of your MissionNANO™.
9.1 Keep it Sharp
WARNING: Before cleaning, adjusting, or
replacing the blades, turn your MissionNANO™
OFF and put on protective gloves.
WARNING: When fitting new blades, make sure
you replace ALL the blades. Always use new
screws when fitting blades. This is important to
ensure blade retention and balance the blade turning
disc. Failure to use new screws could cause serious
injury.
MissionNANO™ does not cut grass like other mowers.
Its cutting blades are razor sharp on 2 edges and rotate in both directions for maximum cutting capacity (See
Fig. L). Each blade of your MissionNANO™ has 2 cutting edges. The blade turning disc will make forward
and reverse rotation at random to use both cutting edges and minimize the frequency of replacing the blades.
Each cutting blade will last up to 2 months when it is programmed to mow everyday. Always check to see if
the blades are chipped or damaged and replace them if they are. When the cutting blades are dull and worn
out, they should be replaced with the spare blades provided with your MissionNANO™. Spare blades are also
available at your nearest Kress retailer.
A. Replace the Blades
After some time, usually every season, your MissionNANO™’s Blades will need to be replaced. When
1
2

17
EN
replacing the blades, make sure to replace ALL of them at the same time. You can replace them with one of
the spare blade kits and extra blade screws supplied with your MissionNANO™.
Before attempting to replace your MissionNANO™’s blades, turn the power off and put on protective gloves
and follow these steps:
1. Gently flip the MissionNANO™ over.
2. Remove the battery cover and remove the battery.
3. Take the screws off the blades with a screwdriver.
(See Fig. M)
4. Firmly screw on the new blades.
5. Refit the battery and the battery cover.
Important: After screwing the blade to the blade
disc, make sure the blade is able to spin freely.
9.2 Keep it Clean
WARNING: Before cleaning, turn your
MissionNANO™ OFF. Put on protective gloves
before cleaning the blade turning disc and do not rinse or
flush with water.
A. Cleaning the Body
Your MissionNANO™ will live a much happier and
longer life if it is cleaned regularly. Although, since your
MissionNANO™ is an electric machine, you will need
to take care when cleaning. DO NOT use a hose, high
pressure washers or otherwise pour running water on
your MissionNANO™. It is best to use a spray bottle filled
with water. When cleaning the machine body, use a soft
brush or clean cloth and avoid using solvents or polishes
(See Fig. N). Lastly, remove all build up of grass clippings
and debris.
B. Cleaning the Underside
Again, it is important that you power the MissionNANO™ OFF and wear protective gloves before touching
the blade turning disc.
First, flip your MissionNANO™ upside down to expose its underside. Here you will see the blade disc, the
chassis, and the front wheel and driving wheels. Clean everything thoroughly with a soft brush or moist rag.
WARNING: NEVER clean the underside of MissionNANO™ with running water. Component
damage can occur. (See Fig. O1, O2)
Rotate the blade disc to ensure it rotates freely. Check the blades spin freely around the fixing screws. Remove
any obstructions.
IMPORTANT: Remove any lodged debris so that it does not cause a crack in the blade disc. Even
the tiniest crack can decrease your MissionNANO™ 's mowing output.

C. Clean the contact pins and the charging strips
Clean the contact pins located on the charging base and the charging strips located on the MissionNANO™
using a cloth. Remove any built up grass clippings or debris around the contact pins and charge strips
periodically to ensure the MissionNANO™ successfully charges each time.
9.3 Battery Life
The heart of the MissionNANO™ is its 20V Li-Ion Battery. For proper storage of the battery, make sure it is fully
charged and kept in a cool dry place between (-20°C~60°C).
NOTE: The recommend MissionNANO™ operation temperature is between 0-55oC.
The life-span of the MissionNANO™’s battery depends on various factors, such as:
• The length of the mowing season in your region
• Amount of hours the MissionNANO™ mows per day
• Battery maintenance during storage
MissionNANO™ can be charged manually without the boundary wire.
1. Connect the charging base to a suitable power supply. The green light on the charging base will
turn on.
2. Manually dock the MissionNANO™ into the charging base while the MissionNANO™ is powered
off. (See Fig. P)
3. The green light on the charging base will turn to red, and the battery indication light will flash
green and red. MissionNANO™ will begin to charge.
9.4 Winter Hibernation
Your MissionNANO™ will live longer and healthier if it is allowed to hibernate. So even though it is tough, we
recommend storing your MissionNANO™ in your shed or garage during the winter.
Before you prepare your MissionNANO™ for winter hibernation, we recommend you:
• Thoroughly clean your MissionNANO™
• Fully charge the battery
• Turn the power off
To maximize the battery life, fully charge the battery before storage during winter.
WARNING: Protect the underside of MissionNANO™ from water. NEVER store MissionNANO™ upside
down outdoors.
The boundary wire can be left in the ground although its ends should be protected, such as placed in a tin can
with grease. If the charging base is left outside for the winter, leave the boundary wire connected.
NOTE: When bringing MissionNANO™ back to work after winter hibernation, make sure the charging strips
and contact pins are clean. We recommend using a fine grade emery cloth to clean the contacts. Using the
App, make sure the date and time are correct and send MissionNANO™ back to what it loves doing: mowing.
9.5 Replacing the Battery
WARNING: Power off before attempting any adjustment, replacement or repair.
Before replacing the blades, turn your MissionNANO™ OFF and put on protective gloves.
If you need to replace the battery, follow these steps:
1. Gently turn your MissionNANOTM upside down.
2. Remove the screws on the battery cover. Remove the battery cover. (See Fig. Q1)
3. Lift out the old battery carefully. Press the latch and release the connectors. (See Fig. Q2)
