Robot lawnmower occasionally spins its wheels without moving forward, especially on slopes or wet grass.

Safety first: Turn OFF the mower before moving it manually.

• Check slope: Measure the steepest part of your lawn and compare with the NAC mower's maximum slope rating. Avoid using the mower on slopes beyond its capability.
• Inspect wheel treads: Replace worn drive wheels with new NAC wheels that have sharp tread patterns.
• Adjust mowing schedule: Avoid mowing immediately after rain or watering when the grass is very slippery.
• Reduce load: Remove any non‑standard accessories or added weights that may reduce traction.

Warning: Operating on slopes beyond the rated limit can cause rollovers and damage.
