5. Operating Instructions
Follow these steps for safe and effective operation of your Ryobi lawn mower.
5.1 Adjusting Cutting Height
The mower features 7 levels of cutting height adjustment. Locate the height adjustment lever, typically near one of the wheels or centrally located. Move the lever to select your desired cutting height. For best results, avoid cutting more than one-third of the grass blade length at a time.
5.2 Starting and Stopping the Mower
- To Start: Ensure the battery is installed and the safety key (if present) is inserted. Press and hold the safety button, then pull the bail lever towards the handle. The blades will begin to rotate.
- To Stop: Release the bail lever. The blades will stop rotating.
5.3 Engaging Self-Propulsion
This mower is equipped with a self-propulsion system. To engage, activate the self-propel lever or button (refer to specific controls on your model). The speed can often be adjusted continuously during operation. The self-propulsion can be operated independently of the blades, allowing you to move the mower without cutting.
5.4 Mowing Techniques
- Overlap Passes: Overlap each mowing pass slightly to ensure an even cut.
- EasyEdge Feature: Utilize the EasyEdge grass comb for precise trimming along edges and obstacles.
- Slopes: Mow across slopes, not up and down. Maintain firm footing and avoid sudden changes in direction.
- Grass Collection: Monitor the grass collection bag and empty it when full to maintain optimal cutting performance and prevent clogging.
