Never allow the battery pack to become fully discharged. Getting Started Inspect the lawn Remove stones, sticks, wires, toys, and other objects that could be picked up by the rotating blades. Set the cutting height Remove the battery first. Pull the height adjustment knobs on both sides of the mower frame and set both sides to the same height: 0.6, 1.0, 1.5, or 2.0 inches. Insert the battery Make sure the On/Off switch lever is not squeezed. Insert the battery into the compartment and close the battery compartment cover. Start the mower Press and hold the safety lock button, then pull the On/Off switch lever toward you. Release the safety lock button once the mower powers on. Mow at a steady pace Walk slowly in thick or tall grass. For a healthy lawn, cut one-third or less of the total grass height at one time. Stop the mower Release the On/Off switch lever. Wait for the blades to stop completely before lifting, tilting, carrying, or inspecting the mower. 🚫Do not start in tall grass. Set the mower to a higher cutting height when mowing uneven ground, tall grass, or thick growth. ⚠️ Slope safety: Mow across slopes, not up and down. Do not mow wet grass or excessively steep slopes. Maintenance & Care 🚫Always stop the mower, remove the battery, and wait for all moving parts to stop before cleaning, adjusting, repairing, or inspecting the mower. 1 Clean after each mowing session Remove grass clippings and debris with a dry cloth or hand brush. A damp cloth may be used, but do not let water enter the equipment. 2 Do not use running water Do not clean the reel mower with running water or high-pressure water. Avoid harsh solvents and cleaning agents. 3 Inspect hardware Check all nuts, bolts, screws, and handles for tightness before each use. 4 Check the grass collection bag Inspect the grass bag frequently for wear or damage. Replace damaged components with genuine parts. 5 Check cutting performance with paper With the battery removed, turn the mower upside down and insert paper between the steel blades and cutting bar. Turn the wheel by hand. The blades should slice paper evenly along the cutting bar. 6 Adjust the cutting bar if needed If cutting is intermittent, use the supplied hex key to tighten the nearest adjustment bolt clockwise about 1/8 turn. Do not overtighten. 7 Store dry Clean the exterior with a soft brush and cloth, then store the mower in a dry place. Do not place other objects on top during storage.
