Question 2

How do I remove the battery from the Cramer RM2000 lawn mower?

Accepted Answer

The Cramer RM2000 lawn mower is equipped with a 24 V / 2.0 Ah rechargeable Lithium-ion battery. To safely remove the battery, you must first completely stop the mower and remove the safety key. Wear protective gloves and use a Torx T20 wrench, as the battery cover is secured with four screws of this type.

Removal procedure:

Turn the mower upside down to access the battery compartment located under the chassis
Remove the four Torx T20 screws that hold the battery cover in place
Lift the battery cover to completely remove it
Disconnect the battery terminal connector by gently pulling to avoid damaging the contacts
Lift the battery straight up and remove it from its location

The battery must be handled with care as it is a Lithium-ion battery. Before long-term storage or winterizing the mower, ensure that the battery is fully charged. A partially charged battery may get damaged and become unusable. If you replace the battery, always use an original Cramer battery (reference 211022355) to ensure the proper functioning and safety of your mower.

The old battery must not be thrown in the regular trash. According to environmental regulations, Lithium-ion batteries must be recycled or taken to a specialized collection point that accepts this type of battery. Check with your municipality for available collection points near you.

Question 3

How to reset the Cramer RM2000 robotic mower when the light is solid green but the robot does not start?

Accepted Answer

When the green light on your Cramer RM2000 robotic mower is solid (continuously lit), it indicates that the mower is in operational mode. It may be charging, parked in the charging station, paused, or ready to mow. If it does not start, follow these steps to reactivate or reset it:

Step 1: Check the position of the safety key. Insert the safety key into the slot located under the mower and turn it counterclockwise to the "1" position (Enable). This position activates the mower. If the key is not properly positioned, the mower cannot start.

Step 2: Properly activate the START button. Slide the lock of the START button back, then press firmly on the START button. The green light should briefly flash, then remain solid once the mower is operational. If nothing happens, the mower is likely in pause mode and this action will restart it.

Step 3: Reset the mower if it does not respond. Press the STOP button to completely stop the mower and remove the safety key. Then open the battery compartment, remove the battery, and wait about 10 to 15 seconds. This operation resets the internal circuits of the mower. Reinsert the battery firmly ensuring it clicks into place, then close the compartment.

Step 4: Restart normally. Insert the safety key and turn it to the "1" position, slide the lock of the START button back, then press START. The mower should now start and resume normal operation with the solid green light.

If after these actions the light remains solid but the mower still does not start or if you see a flashing red light (error indicator), this signals a more significant technical issue. In this case, refer to the "Troubleshooting" section of the manual to identify the specific error code, or contact your Cramer dealer with your mower's serial number for specialized assistance.

Question 4

What does the flashing blue light on the charging station of the Cramer RM2000 robotic mower mean and how can I resolve this issue?

Accepted Answer

The flashing blue light on your Cramer RM2000 robotic mower's charging station indicates a specific problem: the boundary wire is broken, disconnected, or detached. This wire defines the working area of the robot and is essential for its operation. The robot cannot function properly until this issue is resolved.

Start by checking the most common connection points. Inspect the cable connectors at the back of the charging station and ensure they are securely plugged in. Also, check that the boundary wire has not been accidentally disconnected at the entry points of the station. If the connections seem fine, follow the boundary wire all around your garden to look for visible damage: cut wire, pulled by a root, damaged by gardening tools, or deteriorated by repeated passage of the mower.

If you find a visible break or damaged area, repairing it requires a specific connection kit for robotic mowers. The kit should contain wire connectors, cable stakes, and a replacement segment of boundary wire. Cut about 60 centimeters from each side of the damaged area to remove any degraded section, then insert both ends of the wire into a connector designed for this purpose and secure it tightly with the stakes.

If you do not identify a visible break, the problem may be a micro-crack, oxidation of the connectors, or a partial disconnection. Unplug the charging station from the electrical outlet, wait 10 seconds, then plug it back in. Check if the light remains flashing blue or changes color. If the light turns solid green, the problem was a simple temporary disconnection. If the light remains blue, clean the connectors with a dry cloth and reinsert them firmly.

For a systematic search for an invisible break, you can use the cable splitting method: disconnect the boundary wire halfway along its path and test each half independently by reconnecting one part. The flashing blue light will indicate which side the break is on, allowing you to focus your search. Another option is to use a portable AM radio: an intact cable creates interference with the radio signal, allowing you to trace the interruption to the break point.

After a repair, reconnect the station, wait for the light to turn solid green, then test the robot by placing it on the charging station. If the light remains flashing blue after checking the connections and repairs, it may indicate an electronic failure of the station itself. In this case, contact Cramer's customer service for technical assistance or a warranty replacement.
