Across the slope, not up or down, to reduce slipping.

Electrical Safety and Weather Awareness

Moisture is an electric mower’s greatest enemy. Even a little dampness can cause severe hazards if ignored.

Never mow in the rain or when the grass is wet. Moisture can seep into electrical components, leading to shock or short-circuit damage. Use outdoor sockets protected by RCD (Residual Current Device) breakers to cut power instantly in emergencies.

Store the mower indoors when not in use, and never leave cords plugged in outside overnight. Wait until the lawn is completely dry before mowing, especially in early mornings with dew.

Can I mow when it’s drizzling lightly?
No. Always wait until the grass and ground are dry.

What is an RCD?
A device that prevents electrocution by instantly shutting off power during faults.

Is it safe to mow after rain if it looks dry?
Touch the grass first — if damp, wait longer.

Can I plug the mower into an indoor socket via window?
Not recommended; use outdoor-rated sockets instead.
