8.7Replacing the battery

The battery is maintenance-free, but has a limited life span of 2 to 4 years.

Battery life is dependent on the length of the season and how many hours a day the R40Li is used. A long season or many hours of use a day means that the battery must be replaced more regularly.

IMPORTANT INFORMATION

Fully charge the battery at the end of the season before winter storage.

Replacing the battery

If the operating times for the mower are shorter than normal between charges, this indicates that the battery is getting old and eventually needs replacing. The battery is fine as long as the mower maintains a well-cut lawn.

IMPORTANT INFORMATION

Always use original batteries. Compatibility with other batteries cannot be guaranteed.

1.Set the main switch to the 0 position.

2. Lower the cutting height to its lowest position.

3. Turn the mower upside down. Place the mower on a soft and clean surface to avoid scratching the body and the display cover.

4. Clean around the battery cover.

5.Unscrew the four screws to the battery cover

(Torx 20) and remove the battery cover.

6.Pull out the battery by pulling on the strap.

7. Fit a new original battery.

NOTE! Press on the contact strip to fit the battery in place and not on the battery pack itself.

8. Fit the battery cover. If the seal on the battery cover is visibly damaged, the entire battery cover must be replaced.

9.Screw in place the four screws for the battery cover (Torx 20).

10.Reset the cutting height to the required level.
