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, Mission™ 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 Mission™ with a defective on/off switch.
Switch off the machine before carrying out any service or maintenance.
Here’s how to take care of your Mission™.

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 4 edges and rotate in both directions for maximum cutting capacity. Each blade of your Mission™ has 4 cutting edges. The blade turning disc will make forward and reverse rotations at random to use 4 cutting edges and minimize the frequency of replacing the blades. And with the 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 Mission™. Spare blades are also available at your nearest Kress retailer.

A. Replace the blades
Usually, your Mission™ ‘s blades need to be reversed each month and replaced every 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 Mission™.![Kress KR121E Robot Lawn Mower

• Figure 3](https://manuals.plus/wp-content/uploads/2022/08/Kress-KR121E- Robot-Lawn-Mower-Figure-3.jpg)

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.
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 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. Lastly, remove all buildup 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.
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 the Mission™ using a cloth. Remove any built-up grass clippings or debris around the contact pins and charge strips periodically to ensure the Mission™ successfully charges each time.

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

• The length of the mowing season in your region
• Amount of hours the 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 the Mission™ into the charging base while the Mission™ is powered off.
3. The green light on the charging base will be flashing and Mission™ will begin to charge.

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 canwith grease. If the charging base is left outside for the winter, leave the boundary wire connected.

NOTE: When bringing the 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.

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:

1. Gently turn your Mission™ 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.
