Safe operation practices

• Training
  • a) Read the instructions carefully. Make sure you understand the instructions and are familiar with the controls and the proper use of the appliance.
  • Never allow people unfamiliar with these instructions or children to use the appliance. Local regulations can restrict the age of the operator.
  • The operator or user is responsible for accidents or hazards occurring to other people or their property.

Preparation

• a) Confirm that the virtual boundary is established as instructed and that the virtual is regularly maintained. Before each working cycle, the machine goes around the working area to check whether the virtual boundary exists; if it does not exist, the machine will shut down. The virtual boundary specifies the work area where the machine is allowed to operate. The RTK antenna in the machine senses when it is approaching the virtual boundary. When the machine hits an obstacle or approaches the virtual boundary, the product selects a new direction.
• Periodically inspect the area where the appliance is to be used and remove all stones, sticks, wires, bones, and other foreign objects.
• Periodically, visually inspect to see that the blades, blade bolts,s, and cutter assembly
  are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance.
• On multi-spindle appliances, take care as rotating one blade can cause other blades to rotate.
• WARNING! The lawnmower shall not be operated without the guard in place.

Accessories

We recommend that you purchase genuine accessories listed in the above list from the same store that sold you the tool. Refer to the accessory packaging for further details. Store personnel can assist you and offer advice.

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 RTKn may be programmed to operate at any time or frequency. It is not intended for digging, sweeping, or snow cleaning.

Maintenance
Your MissionTM RTKn 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 RTKn 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 MissionTM RTKn.

Keep it Sharp

• WARNING: Before cleaning, adjusting, or replacing the blades, turn your MissionTM RTKn 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 RTKn 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. Redesigned blade profile better prevents grass clippings from getting caught in the gap between the disc and the blade. And with new material, the service life of each cutting blade will be 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 RTKn. Spare blades are also available at your nearest Kress retailer.

A. Replace the blades
Usually, your MissionTM RTKn’s blades need to be reversed each month and replaced every week. You can adjust the frequency of replacing the blades according to the cutting quality of the lawn. 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 RTKn.

Before attempting to replace your MissionTM RTKn’s blades, turn the power off and put on protective gloves, and follow these steps:

1. Gently flip the MissionTM RTKn 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 RTKn OFF. Put on protective gloves before cleaning the blade turning disc, and do not rinse or flush with water.
• WARNING! YOUR MissionTM RTKn can only be washed by using a hose! DO NOT use a high-pressure washer on your MissionTM RTKn. High-pressure water can go inside the sealings and damage electronic and mechanical parts.

A. Cleaning the Body
Your MissionTM RTKn will live a much happier and longer life if it is cleaned regularly. Since your MissionTM RTKn is an electric machine, you will need to take care when cleaning. Hose water is clean. It is best to use a spray bottle filled with water. When cleaning the machine body, use a soft brush or a 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 MissionTM RTKn OFF and wear protective gloves before touching the blade turning disc. First, flip
  your MissionTM RTKn 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. Hose water is clean.
• Rotate the blade disc to ensure it rotates freely. Check the blades spin freely around the fixing screws. Remove any obstructions.
• IMPORTANT: Remove any stuck debris so that it does not cause a crack in the blade disc. Even the tiniest crack can decrease your MissionTM RTKn’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 MissionTM RTKn using a cloth. Remove any built-up grass clippings or debris around the contact pins and charge strips periodically to ensure the MissionTM RTKn successfully charges each time.

Battery Life

• The heart of the MissionTM RTKn 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 °CC).
• NOTE: The recommended MissionTM RTKn operation temperature is between 0-55 °C.
• The life span of the MissionTM RTKn’s battery depends on various factors, such as:
  • The length of the mowing season in your region
  • Amount of hours the MissionTM RTKn mows per day
  • Battery maintenance during storage

MissionTM RTKn can be charged manually.

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

Winter Hibernation
Your MissionTM RTKn will live longer and healthier if it is allowed to hibernate. So even though it is tough, we recommend storing your MissionTM RTKn in your shed or garage during the winter.

Before you prepare your MissionTM RTKn for winter hibernation, we recommend you:

• Thoroughly clean your MissionTM RTKn
• 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 RTKn from water. NEVER store MissionTM RTKn upside down outdoors.
• NOTE: When bringing the MissionTM RTKn back to work after winter hibernation, make sure the charging strips and contact pins are clean. We recommend using fine-grade emery cloth to clean the contacts. Using the app, make sure the date and time are correct and send MissionTM RTKn 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 RTKn OFF and put on protective gloves.
• If you need to replace the battery, follow these steps:
  1. Gently turn your MissionTM RTKn upside down.
  2. Remove the screws on the battery cover. Remove the battery cover.
  3. Remove the screws on the sheet metal. Remove the sheet metal.
  4. Press the latch and release the connectors as the picture. Lift out the battery box carefully.
     NOTE: Do not pull by the cables. Hold the connectors and release the latch.
  5. Open the battery box, then lift out the battery carefully. Replace the old battery with the new one.
  6. Put the battery box back in its position and plug the connectors. Refit the sheet metal.
  7. Place the cover back in its position and tighten the screws.
