4.3 Grass Bag Attachment
For bagging clippings, lift the rear discharge door and hook the grass bag onto the mower's frame. Ensure it is securely attached to prevent clippings from escaping. For mulching, remove the grass bag and ensure the mulching plug (if included separately) is installed.
4.4 Cutting Height Adjustment
The mower features a 7-position single-point height adjustment lever. Locate the lever on the side of the mower deck. Pull the lever outwards and move it forward or backward to select the desired cutting height. Release the lever to lock it into position.
5. Operating Instructions
5.1 Starting the Mower
- Ensure the battery is fully charged and properly installed.
- Press and hold the safety button, then pull the bail switch lever towards the handle. The mower will start.
- Release the safety button once the mower is running.
5.2 Mowing Techniques
For optimal results, mow in straight, overlapping lines. Avoid cutting more than one-third of the grass blade length at a time. The load-sensing technology will automatically adjust motor speed for consistent cutting performance. For areas with thicker grass, a slower pace may be beneficial.

5.3 Using LED Headlights
The mower is equipped with high-intensity LED headlights for improved visibility in low-light conditions. These lights activate automatically or can be manually controlled depending on the model variant. Refer to the specific controls on your unit for activation.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your mower. Always remove the battery before performing any maintenance.
6.1 Cleaning
- After each use, clean the mower deck and exterior with a damp cloth.
- Remove any grass clippings or debris from the underside of the deck to prevent buildup and ensure proper cutting.
- Do not use water hoses or high-pressure washers directly on the mower, as this can damage electrical components.
6.2 Blade Care
Periodically inspect the cutting blade for sharpness and damage. A dull or damaged blade can lead to an uneven cut and increased battery drain. If necessary, have the blade sharpened or replaced by a qualified service technician. Always wear heavy gloves when handling the blade.
6.3 Battery and Charger Care
- Store batteries in a cool, dry place away from direct sunlight and moisture.
- Charge batteries fully before storage and periodically during extended storage periods to maintain battery health.
- Use only the Ryobi-approved charger for your 40V battery.
6.4 Storage
For compact storage, the telescoping handle can be folded down using the quick-release knobs. The mower is designed to be stored vertically, saving floor space. Ensure the mower is clean and dry before storing.
