Intended Use

The garden product is intended for domestic lawn mowing. It is designed to mow often, maintaining a healthier and better looking lawn than ever before. Depending on the size of your lawn, MissionTM may be programmed to operate at any time or frequency. It is not intended for digging, sweeping or snow cleaning.

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 MissionTM with a defective on/off switches.
• Switch off the machine before carrying out any service or maintenance.
• Here’s how to take care of your MissionTM.

Keep it Sharp

WARNING : Before cleaning, adjusting, or replacing the blades, turn your MissionTM 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 MissionTM does not cut grass like other mowers. Its cutting blades are razor sharp on 4 edges and rotate in both directions for maximum cutting capacity. Each blade of your MissionTM has 4 cutting edges. The blade turning disc will make forward and reverse rotation at random to use 4 cutting edges and minimize the frequency of replacing the blades. And with new material, the service life of each cutting blade will be 3 times longer than that of other brands’ when it is programmed to mow every day. 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 MissionTM. Spare blades are also available at your nearest Kress retailer.

Replace the blades

Usually your MissionTM’s blades need to be reversed each month and replaced each 2 months. 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 MissionTM. Before attempting to replace your MissionTM’s blades, turn the power off and put on protective gloves and follow these steps:

1. Gently flip the MissionTM over.
2. Remove the battery cover and remove the battery.
3. Take the screws off the blades with a screwdriver.
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.

Keep it Clean

WARNING : Before cleaning, turn your MissionTM OFF. Put on protective gloves before cleaning the blade turning disc and do not rinse or flush with water.

Cleaning the Body

Your MissionTM will live a much happier and longer life if it is cleaned regularly. Since your MissionTM 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 MissionTM. 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. Lastly, remove all build up of grass clippings and debris.

Cleaning the underside

Again, it is important that you power the MissionTM OFF and wear protective gloves before touching the blade turning disc. First, flip your MissionTM 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 MissionTM with running water. Component damage can occur.
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 MissionTM’s mowing output.

Clean the contact pins and the charging strips

Clean the contact pins located on the charging base and the charging strips located on the MissionTM using a cloth. Remove any built up grass clippings or debris around the contact pins and charge strips periodically to ensure the MissionTM successfully charges each time.

Battery Life

The heart of the MissionTM 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 ± 5°C).
NOTE : The recommend MissionTM operation temperature is between 0ºC – 45ºC. The life-span of the MissionTM’s battery depends on various factors, such as:

• The length of the mowing season in your region
• Amount of hours the MissionTM mows per day
• Battery maintenance during storage

MissionTM can be charged manually without the boundary wire.

• Connect the charging base to a suitable power supply. The green light on the charging base will turn on.
• Manually dock the MissionTM into the charging base while the MissionTM is powered off.
• The green light on the charging base will be flashing and MissionTM will begin to charge.

Winter Hibernation

Your MissionTM will live longer and healthier if it is allowed to hibernate. So even though it is tough, we recommend storing your MissionTM in your shed or garage during the winter.
Before you prepare your MissionTM for winter hibernation, we recommend you:

• Thoroughly clean your MissionTM
• 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 MissionTM from water. NEVER store MissionTM 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 the MissionTM 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 MissionTM back to what it loves doing: mowing.

Replacing the battery

WARNING : Power off before attempting any adjustment, replacement or repair. Before replacing the blades, turn your MissionTM OFF and put on protective gloves.

If you need to replace the battery, follow these steps:

1. Gently turn your MissionTM upside down.

2. Remove the screws on the battery cover. Remove the battery cover.

3. Lift out the old battery carefully. Press the latch and release the connectors.
   NOTE : Do not pull by the cables. Hold the connectors and release the latch.

4. Connect a new original battery by attaching the connectors until they click into position.

5. Fit the battery as shown. Place the cover back in its position and tighten the screws.

Troubleshooting

There is no power.

| Check the charging base is connected properly to the charger and the charger is connected to a suitable power supply.

Red light turns on the charging base.

|

The boundary wire isn’t connected.

| Check that the boundary wire has been connected correctly to the charging base. Check there are no breaks in the boundary wire, especially in the wire ends.
Your MissionTM is inside its working area but the display says “outside working area” and the LED is green.|

The boundary wire ends are clamped incorrectly.

|

Reverse the boundary wire ends.

MissionTM cannot correctly dock with the Charging base.

| Environmental influences.| Restart MissionTM.
Poor connection caused by debris on the charging strip.| Clean the contact pins located on the charging base and the charging strip on MissionTM using a cloth.

MissionTM runs outside the boundary wire. MissionTM does not mow an area within a boundary wire zone. MissionTM reverses or rotates erratically near the boundary wire.

| The boundary wire of another MissionTM or another branded robotic mower is positioned too closely.| Ensure your MissionTM boundary wire has at least 1m of spacing between the neighboring boundary wire.
The boundary wire has been installed with acute angles.| Check the boundary wire to ensure the angles are smooth.
In wet conditions, the boundary wire electric signal may leak where wire has been joined or repaired.|

Check boundary wire joints. Insulate to provide a fully waterproof connection.

There is boundary wire electric signal leakage due to broken insulation.| Repair damaged boundary wire insulation with insulation tape.
The cutting area is larger than the allowable cutting area for MissionTM.|

Decrease the cutting area.

MissionTM exits the boundary wire due to high speed when going down a hill.| The boundary wire is placed on a slope steeper than 17% (10°).| Reposition the boundary wire away from slopes that are steeper than 17% (10°).

If your mission does not work correctly, follow the troubleshooting guide below. If the fault persists, contact your dealer.
