4. Setup
4.1. Assembly
Your lawn mower may require minor assembly upon unboxing. This typically involves unfolding and securing the handle, and attaching the grass collection bag if applicable. Refer to the quick start guide included in the packaging for detailed visual instructions.
4.2. Battery Charging
Before first use, fully charge the 60V 4Ah Lithium-Ion battery. Connect the charger to a standard power outlet and insert the battery. The charger's indicator lights will show the charging status. A full charge typically takes approximately 60 minutes with the 4A rapid charger.
4.3. Battery Installation
Open the battery compartment cover on the mower deck (refer to Figure 3.3). Slide the fully charged battery into the compartment until it clicks securely into place. Close the cover firmly.
5. Operating Instructions
5.1. Adjusting Cutting Height
The mower features a 7-position one-touch height adjustment. Locate the height adjustment lever near the wheels (refer to Figure 3.4). Pull the lever outwards and move it to the desired cutting height, ranging from 1 1/4" to 3 3/4". Ensure all wheels are set to the same height for an even cut.
5.2. Starting the Mower
To start the mower, ensure the battery is installed. Press and hold the safety button, then pull the bail lever towards the handle. The motor will start. Release the safety button once the motor is running.
5.3. Self-Propelled Function
This model is equipped with self-propelled technology and variable speed control. To engage the self-propelled function, activate the separate self-propel lever (if present, consult your quick start guide for exact location). Adjust the speed as needed for comfortable operation.
5.4. Mowing Techniques
For optimal results, mow when the grass is dry. Overlap cutting swaths slightly to ensure complete coverage. Avoid cutting more than one-third of the grass blade length at a time. The 3-in-1 functionality allows for mulching, bagging, or side discharge. Attach the grass bag for collection or the side discharge chute for dispersal.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your lawn mower.
6.1. Cleaning
After each use, disconnect the battery and clean the mower deck, blades, and grass bag. Use a damp cloth to wipe down exterior surfaces. Do not use water jets or immerse the mower in water.
6.2. Blade Care
Periodically inspect the cutting blade for sharpness and damage. A dull or damaged blade can lead to poor cutting performance and strain the motor. If necessary, have the blade sharpened or replaced by a qualified service technician. Always wear heavy-duty gloves when handling the blade.
6.3. Storage
Store the mower in a dry, secure location, away from direct sunlight and extreme temperatures. The foldable handle allows for compact storage. Remove the battery before storing for extended periods.
