Adjusting Cutting Height

Mowing Techniques
The Makita XML10CT1 offers versatile 3-in-1 functionality:
- Bagging: For collecting grass clippings, ensure the grass collector bag is properly installed and securely attached to the rear discharge opening.
- Mulching: To finely cut and redistribute clippings back onto the lawn as natural fertilizer, insert the mulching plug into the rear discharge opening.
- Rear Discharge: For direct discharge of clippings, operate the mower without the grass bag or mulching plug installed.

Maintenance
General Cleaning
After each use, disconnect the batteries and clean the mower deck, wheels, and grass bag. Use a damp cloth to wipe down surfaces. Avoid using high-pressure water jets directly on electrical components or the motor housing.
Blade Care
Regularly inspect the cutting blade for sharpness, nicks, or damage. A dull or damaged blade can significantly reduce cutting performance and put strain on the motor. If the blade is dull, bent, or severely worn, it should be sharpened or replaced by a qualified service center. Always disconnect batteries before inspecting or servicing the blade.
Battery and Charger Storage
Store batteries in a cool, dry place, away from direct sunlight, moisture, and extreme temperatures. Do not store fully discharged batteries for extended periods. Store the charger indoors in a dry environment.
Mower Storage
For compact storage, the mower handles can be easily folded down. Clean the mower thoroughly before storing it in a dry, protected area, away from children and unauthorized personnel.
