The MissionTM chooses its direction at random. It will make sure your entire lawn is evenly mowed without
leaving unattractive mowing paths (See Fig. A).
5.1 How does my MissionTM know what to mow?
Congratulations on your new purchase of Mission
TM
and welcome to the care-free life of automatic mowing. In
the following, we would like to help you better understand how your Mission
TM
thinks.
5. Understanding Your MissionTM
A

11
EN
Your MissionTM is capable of doing things on its own. MissionTM 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. MissionTM 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 MissionTM needs to recharge, it will stop mowing and follow the boundary wire in an anti-clockwise
direction back to its Charging Base. MissionTM is pre-programmed to mow the grass near the boundary wire
once a week. By default, MissionTM will mow near the boundary wire every Monday of its system time.
If you don’t want to enable boundary cut, deactivate it via your smartphone or by the control panel in “Work
Time - Customize work time - Monday”.
B. Rain sensors
MissionTM is equipped with a rain sensor which detects
rain and tells MissionTM to stop mowing and follow the
boundary wire back to its charging base (See Fig. B).
MissionTM will resume mowing after passing the Delay
Time. the default Delay time is 180mins. Delay time
setting can be changed via MissionTM APP or by the
control panel in “General settings - Rain start delay”.
When the rain sensors are wet, MissionTM returns to its
charging base. When the rain sensors dry, MissionTM 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 ON/OFF key. After the
power cycle has been performed you can operate again.
NOTE: If the delay time is set to 0, MissionTM will continue mowing.
C. Sensing the boundary wire
MissionTM 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 MissionTM to stop mowing, simply press the STOP button on top of the mower. To start
mowing, press the ON/OFF key and input the PIN code. Press , then press .
If MissionTM senses something is wrong, it will display a fault message on the display. For information on these
messages, refer to the Error Messages. MissionTM will turn off if it does not receive any input from the user
within 20 min.
To resume:
• Press the ON/OFF Key to OFF
• Correct the problem (refer to Error Messages)
• Press the ON/OFF Key to ON
• Press , then press
• Now the MissionTM will begin to mow!
5.2 How does my MissionTM know where to go?

12
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, MissionTM is
designed with a protective cover underneath that prevents objects from touching the turning blades and/or
injury. (See Fig. F)
5.4 How efficiently will my MissionTM mow the grass?
Mowing times are different for every lawn depending on the factors mentioned below. Gradually adjust the time
you allow MissionTM to mow each day until you find the most suitable setting.
Your MissionTM 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, MissionTM 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.
MissionTM’s cutting height can be adjusted between 3cm-6cm. Before starting your MissionTM 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,

13
EN
6cm. (See Fig. G)
Your MissionTM 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 MissionTM is afraid of lightening storms. In case of
a lightning storm, protect MissionTM by unplugging the
charging base, disconnecting the boundary wire, and
making sure MissionTM is not allowed to charge.
Your MissionTM loves mowing grass and requires the cutting blades to be kept in good condition to cut at
its best. MissionTM can do most things by itself, but will sometimes need your help to prevent damage to
itself.
• Never let MissionTM travel over gravel.
• Remove or prevent access to obstacles that MissionTM could accidentally climb on and damage its blade
turning disc.
• Remove all debris and foreign objects from your lawn.
6. App
Your MissionTM is able to connect with smartphone. Using MissionTM App for your smartphone, you can
change your MissionTM's general settings, and view the machine's status and error messages.
To connect smartphone to your MissionTM:
Step 1: To download the MissionTM 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 MissionTM APP, and then follow the instructions to connect to your Wi-Fi.
*The Serial No. can be found at the rear of MissionTM as shown in Fig. H.
Only suitable for
iOS 11.0 or higher
NOTE:
1. If your Wi-Fi information changes, MissionTM needs to be re-set according to Step 1 to 2.
2. When MissionTM is located in an area with low or no Wi-Fi signal, instructions sent from the mobile App may
not be executed immediately. MissionTM 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 MissionTM, 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 MissionTM 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 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
MissionTM follow and check the path by pressing and . This will allow MissionTM to adjust to its new
environment.
While observing MissionTM you can easily make alterations to the boundary wire to ensure MissionTM's
trouble-free tracking when locating the charging station. Confirm that MissionTM 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 Mission™ 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 Mission™ with defective on/off switch.
Switch off the machine before carrying out any service or maintenance.
Here's how to take care of your Mission™.
9.1 Keep it Sharp
WARNING: Before cleaning, adjusting, or
replacing the blades, turn your Mission™ 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.
The Mission™ 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 Mission™ 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 every day. Always check to see if the blades
1
2

16
EN
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 Mission™. Spare blades are also available at your
nearest Kress retailer.
A. Replace the Blades
After some time, usually every season, your Mission™’s blades will need to be replaced. When 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 Mission™.
Before attempting to replace your Mission™’s blades,
turn the power off and put on protective gloves and follow
these steps:
1. Gently flip the Mission™ 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 Mission™ OFF. Put on protective gloves before cleaning
the blade turning disc and do not rinse or flush with water.
A. Cleaning the Body
Your Mission™ will live a much happier and longer life if
it is cleaned regularly. Since your Mission™ 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 Mission™. 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 Mission™ OFF and wear protective gloves before touching the
blade turning disc.
First, flip your Mission™ 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 Mission™ 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 Mission™'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
Mission™ using a cloth. Remove any built up grass clippings or debris around the contact pins and charge
strips periodically to ensure Mission™ successfully charges each time.
9.3 Battery Life
The heart of the Mission™ 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 Mission™ operation temperature is between 0-55°C.
The life-span of Mission™’s battery depends on various factors, such as:
• The length of the mowing season in your region
• Amount of hours Mission™ mows per day
• Battery maintenance during storage
Mission™ 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 Mission™ into the charging base
while Mission™ is powered off.(See Fig. P)
3. The green light on the charging base will turn to
red. Mission™ will begin to charge.
9.4 Winter Hibernation
Your Mission™ will live longer and healthier if it is allowed to hibernate. So even though it is tough, we
recommend storing your Mission™ in your shed or garage during the winter.
Before you prepare your Mission™ for winter hibernation, we recommend you:
• Thoroughly clean your Mission™
• 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 Mission™ from water. NEVER store Mission™ 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 Mission™ 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 Mission™ 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 Mission™ OFF and put on protective gloves.
If you need to replace the battery, follow these steps:
