Keep hands and feet away from the blade area, keep bystanders and pets away, and always remove the batteries and safety key before cleaning, inspecting, adjusting, or storing the mower. ⚠️ Inspect the mowing area first. Remove stones, sticks, wires, toys, and other objects that could be picked up and thrown by the blade. Assembly 🚫 Do not insert the batteries or safety key until assembly is complete. The mower must be fully assembled before operation. 1 Handle Raise and secure the lower handle. › 2 Upper Handle Attach upper handle with knobs and bolts. › 3 Bag or Mulch Install grass bag or mulching plug. › 4 Power Insert both batteries and safety key. Raise the lower handle The mower arrives with the lower handle in the storage position. Lift the lower handle to the desired height and tighten the preassembled knobs. Attach the upper handle Fit the upper handle onto the lower handle. Insert the provided bolts through the aligned holes and secure them with the knobs. Attach the grass collection bag Lift the ejector flap, remove the mulching plug from the rear discharge opening, then hook the grass collection bag onto the mower from above. Release the ejector flap so it rests on the bag. Use the mulching plug instead To mulch, do not attach the grass collection bag. Lift the ejector flap, insert the mulching plug fully into the rear discharge opening, and make sure it is seated securely. Battery + Charging 🔋 Both batteries are required. This mower can only operate with both 24V batteries installed together. One battery alone cannot provide sufficient power. Check charge level Press the battery charge level button. Three LEDs mean high charge, two LEDs mean the charge is decreasing, and one LED means the battery should be charged immediately. Remove the batteries Open the battery compartment cover and press each battery’s push lock button to remove the batteries from the mower. Plug in the charger Connect the dual-port charger to a compatible indoor outlet. Two green lights indicate the charger is powered on. Charge both batteries Slide the battery packs into the charger until locked. Red lights indicate charging. Green lights indicate the batteries are fully charged. Unplug after charging The charger does not automatically turn off when the batteries are fully charged. Unplug the charger when charging is complete. Cutting Height Guide 🚫 Before adjusting cutting height: Turn the mower off, remove both batteries and the safety key, and wait for the blade to completely stop. Position Cutting Height 1 1 in. / 25 mm 2 1.4 in. / 35 mm 3 1.8 in. / 45 mm 4 2.2 in. / 55 mm 5 2.6 in. / 65 mm 6 3 in. / 75 mm Starting + Stopping Set up the mower safely Make sure the switch lever is not being squeezed. Confirm the mower is not touching any foreign object and do not start the mower in tall grass. Insert both batteries and the safety key Install both batteries until they click into place, insert the safety key, and close the battery compartment cover. Start the mower Press and hold the safety lock button, then pull the switch lever toward you. Once the mower starts, release the safety lock button and continue mowing. Stop the mower Release the switch lever to stop the mower. ⚠️ The blade continues rotating briefly after shutoff. Do not tilt, carry, or touch the underside of the mower until the blade has fully stopped. Bagging + Mulching Mode How It Works Bagging Use the grass collection bag to collect clippings. The grass indicator window opens with airflow during mowing and closes when the bag is full and needs to be emptied. Mulching Remove the grass collection bag and insert the mulching plug fully into the rear discharge opening. This allows the blade to cut and recut grass into finer clippings. Mowing Tips 1 Mow dry grass only Do not mow wet grass. Wet grass can reduce cutting performance, stick under the deck, and affect mulching. 2 Use a higher setting for tall grass For tall, thick, or uneven grass, start with a higher cutting height, then mow again at the desired height. 3 Cut one-third or less For a healthy lawn, avoid removing more than one-third of the grass height in a single cut. 4 Slow down in thick grass Reduce walking speed in thick grass to help the mower cut and discharge clippings properly. 5 Mow across slopes On slopes, mow across the face of the slope, not up and down. Do not mow slopes over 15 degrees. Maintenance & Care 🚫 Always remove both batteries and the safety key before cleaning, inspecting, or maintaining the mower. Confirm all moving parts have stopped completely. 1 Clean after each mowing session Remove accumulated grass and debris with a dry cloth or hand brush. A damp cloth with mild soap may be used, but do not allow water to enter the mower. 2 Do not use running water Do not clean the mower with running water or high-pressure water, as water can damage electrical components. 3 Check fasteners Before each use, check nuts, bolts, screws, wheels, and handle knobs to make sure they are secure. 4 Inspect the grass bag Check the grass collection bag frequently for wear or damage and replace it with a genuine part if needed. 5 Inspect the blade If the cut quality drops, the blade may be dull or damaged. Wear gloves when handling the blade and use only the correct replacement blade. Blade Care ⚠️ The blade is sharp. Wear protective gloves or wrap the blade when handling it. Use extra caution and only use original replacement parts specified for this mower. Remove power first Remove both batteries and the safety key from the mower. Access the blade safely Turn the mower on its side to expose the underside of the blade housing. Inspect the blade If the blade is dull or has minor wear, it may need sharpening. If the blade is bent, gouged, or heavily worn, replace it. Use the correct tool The manual lists a 16 mm lug wrench for blade removal. The wrench is not included. Storage 1 Remove batteries and safety key Always remove both batteries and the safety key before storage. 2 Remove the grass bag Empty and remove the grass collection bag before storing. 3 Clean the mower Clean the mower with a damp cloth or hand brush and inspect for loose, worn, or damaged parts. 4 Store indoors Store the mower in a dry, clean, cool indoor area away from children and corrosive materials such as fertilizer or rock salt. 5 Fold for compact storage Loosen the upper handle knobs, fold down the upper handle, then lower the lower handle completely.
