3. Operating Instructions
Before operating, ensure the area is clear of debris and that the grass bag is properly attached.
- Starting the Mower: To start the mower, press the lock-off button located on the handle, then pull the bail switch towards the handle. Release the lock-off button once the motor starts.
- Mowing Technique: Push the mower forward at a steady pace. Overlap each pass slightly to ensure even cutting. Avoid pushing too fast, especially in thick grass, to prevent motor strain and ensure a clean cut.
- Stopping the Mower: Release the bail switch to stop the motor. The blade will cease rotation within a few seconds.
- Emptying the Grass Bag: When the grass bag is full, the mower's performance may decrease. Stop the mower, remove the grass bag, and pour away the grass clippings. Reattach the bag securely before resuming operation.

4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your lawn mower.
- Cleaning: After each use, disconnect the batteries and clean the mower deck and grass bag. Remove any grass clippings, dirt, or debris from the blade area and vents. Use a damp cloth; do not use water jets or harsh chemicals.
- Blade Inspection: Periodically inspect the cutting blade for sharpness and damage. A dull or damaged blade can lead to uneven cuts and strain the motor. Replace or sharpen the blade as needed.
- Battery Care: Store batteries in a cool, dry place away from direct sunlight. Do not expose batteries to extreme temperatures. Charge batteries fully before long-term storage.
- Storage: For compact storage, fold the handle assembly. Store the mower in a dry, protected area.
