FAQs

What is the recommended lawn size for the Kärcher LMO 3-18?

The Kärcher LMO 3-18 is recommended for small to medium-sized lawns, covering areas up to approximately 350 square meters on a single battery charge.

How do I adjust the cutting height?

The cutting height can be adjusted using the single-lever located on the mower body. There are five settings available, ranging from 25 mm to 60 mm.

Can I mulch the grass with this mower?

Yes, the LMO 3-18 features a 2-in-1 mowing system that allows you to either collect grass clippings in the 35 L catcher or use the mulching function to return them to the lawn as natural fertilizer.

What type of battery does it use?

It is powered by Kärcher's 18 V Kärcher Battery Power platform, and the set typically includes a high-performance 18 V 5 Ah lithium-ion battery.

How is the mower stored?

The mower is designed for easy storage with a folding frame that makes it compact. Integrated transport handles also aid in carrying and maneuvering it into storage spaces.

Is the battery charger included?

Yes, a battery and a fast charger are included in the set with the Kärcher LMO 3-18 lawn mower.

What maintenance is required?

Regular maintenance includes cleaning the mower deck and grass catcher after use, storing it in a dry place, and sharpening or replacing the blade annually for optimal cutting performance.

Troubleshooting

Lawn mower does not start.

Ensure the battery is fully charged and correctly inserted. Check that the safety key is in place and the power button is pressed correctly.

Uneven cutting.

Verify the cutting height is set correctly and consistently across the deck. Check the blade for damage or dullness and sharpen or replace if necessary. Ensure grass combs are free of debris.

Grass catcher is not filling effectively.

Empty the grass catcher when it is full. Check for blockages in the chute connecting the mower deck to the catcher. Ensure the mower is not set too low for the grass length.

Reduced motor power or performance.

The iPower system may be reducing speed due to thick grass. Try a higher cutting setting or take narrower passes. Check the battery charge level; a low battery can reduce performance.

Mower stops during use.

This could be due to overheating, a low battery, or a safety mechanism engaging. Allow the mower to cool, check the battery charge, and ensure no obstructions are jamming the blade.
