3.2 Connecting to Power

4. Operating Instructions
4.1 Adjusting Cutting Height
The Stihl RME 235 features a 5-level central cutting height adjustment, ranging from 25 mm to 65 mm. To adjust the cutting height:
- Ensure the mower is switched off and disconnected from the power supply.
- Locate the central cutting height adjustment lever on the side of the mower chassis.
- Pull the lever outwards and move it to the desired height setting. Release the lever to lock it into position.
- Always ensure all wheels are set to the same height.
4.2 Starting and Stopping the Mower
To start the mower, press and hold the safety button, then pull the switch lever towards the handle. To stop, release the switch lever.
4.3 Mowing Techniques
- Mow in overlapping strips to ensure an even cut.
- For best results, mow when the grass is dry.
- Do not overload the motor by attempting to cut excessively long or wet grass in one pass. Adjust cutting height or make multiple passes if necessary.
- Always walk behind the mower; do not run.

4.4 Emptying the Grass Collection Box
The 30-liter grass collection box includes a level indicator. When the indicator signals that the box is full, switch off the mower and disconnect it from the power supply. Carefully remove the grass box and empty its contents. Reattach the box securely before resuming operation.
5. Maintenance
Regular maintenance ensures the longevity and safe operation of your lawn mower.
5.1 Cleaning the Mower
- Always disconnect the power supply before cleaning.
- After each use, clean the underside of the mower deck and the grass collection box to prevent grass buildup. Use a brush or scraper; avoid using water jets directly on electrical components.
- Wipe down the exterior surfaces with a damp cloth.
5.2 Blade Care
A sharp blade is crucial for a clean cut and efficient operation. Inspect the blade regularly for wear, damage, or dullness. If the blade is damaged or excessively dull, it should be sharpened or replaced by a Stihl authorized service center. Never attempt to sharpen or replace the blade without disconnecting the power and wearing appropriate protective gloves.
