Check that the bag is secure Do not operate the unit without the thatch collection bag securely attached, as flying debris may occur. Battery Charging Remove both batteries Open the battery compartment cover and press the push lock buttons to pull both battery packs out. Plug in the charger Insert the charger plug into a 120V AC outlet. Two green lights will illuminate when the charger is powered. Insert the battery packs Slide both battery packs into the dual-port charger until they lock into position. Red lights indicate normal charging. Remove when charged When the charger lights turn green, the batteries are fully charged. Unplug the charger from the outlet first, then remove the batteries. ⚠️ Charger reminder: The charger does not automatically turn off when the batteries are fully charged. Do not leave the batteries connected to the charger for days on end. 🔋 Battery requirement: This unit must be powered by two batteries together. Using one battery will not provide sufficient power. Use two batteries of the same voltage and same capacity. Scarifying + Raking Depth Settings The scarifying/raking depth is adjusted using one knob. Press the knob lock inward while turning the depth adjustment knob until the indicator aligns with setting 1, 2, 3, 4, or 5. Position Scarifying Depth 1 5 mm 2 -0.5 mm 3 -6 mm 4 -8.5 mm 5 -9.5 mm Position Raking / Dethatching Depth 1 10 mm 2 4.5 mm 3 -1 mm 4 -3.5 mm 5 -4.5 mm 💡 Depth note: A negative depth means the tines or blades are working below the ground surface and penetrating the soil layer. Getting Started Prepare the lawn Mow the lawn before scarifying or dethatching. Clear the area of stones, sticks, wire, toys, and other objects that could damage the unit or be thrown by the rotating tines. Choose the correct cylinder Use the scarifying cylinder to open up soil and slice through moss or thick thatch. Use the dethatcher/raking cylinder to rake up lighter thatch and debris. Set the depth Turn off the unit and remove both batteries before changing depth. Select the most suitable depth based on grass height and lawn condition. Install both batteries Open the battery compartment cover and insert both batteries until they click into place. Close the battery compartment cover. Start the unit Press and hold the safety lock button, then pull the switch lever bar toward you. Once the machine starts, release the safety lock button and continue operating. Move slowly forward Push the unit forward at a steady pace. Work in slightly overlapping rows to avoid missing areas. Stop safely Release the switch lever bar. Wait for the tine cylinder to stop completely before lifting, tilting, transporting, or inspecting the unit. 🚫 Do not use on wet grass. Wet grass can stick to the underside of the machine, block discharge, reduce performance, and increase the risk of slipping. ⚠️ Overload protection: If the unit shuts off from overload, turn it off, remove both batteries, let it cool for 5 minutes, clear the cause, and then restart. Scarifying vs. Raking 1 Scarifying Use the 7-blade scarifying cylinder to scratch through and between the grass, remove unwanted material, and open the soil for better aeration. 2 Dethatching / Raking Use the 24-tine raking cylinder to scratch the surface of the lawn and pick up lighter debris for improved oxygen absorption, airing, and drainage. 3 Best operating pattern Work in straight lines along one side of the lawn with slightly overlapping rows. Circle around flower beds and pay extra attention when changing direction. 4 Seasonal guidance The manual recommends scarifying in spring between April and May because lawns recover better during this season. In wet summers, scarify again in late summer with a decreased depth setting. Avoid scarifying during hot weather. 5 Raking frequency The manual recommends aerating/raking every 4–6 weeks depending on the condition of the lawn. Changing the Cylinder 🚫 Always remove both batteries and wait for the cylinder to stop completely before changing cylinders. Wear protective gloves because the cutting devices are sharp and may become hot during use. Remove the thatch collection bag Lift the ejector flap and remove the collection bag from the mounting hooks. Place the machine upside down Place the unit on a flat, stable surface to access the underbody. Unlock the installed cylinder Remove the lock screw and open the cylinder lock that secures the scarifying cylinder. Remove the cylinder Lift the installed cylinder up and remove it from the housing. Install the other cylinder Insert the replacement cylinder and press it into the holder. Refasten the cylinder lock and secure it with the lock screw. Return to operating position Place the unit back on its wheels, reinstall the collection bag, and confirm everything is secure before use. Maintenance & Care 🚫 Remove both batteries before cleaning, inspecting, adjusting, servicing, transporting, or storing the unit. Wait until all moving parts stop completely. 1 Keep hardware tight Check that all nuts, bolts, screws, covers, and guards are secure and in safe working condition before use. 2 Empty the collection bag often Empty the thatch collection bag frequently during use. The manual recommends emptying it when it is half full because a full bag reduces performance. 3 Clean with a brush or cloth Clean the machine with a brush or cloth. Do not use solvents or water to remove dirt. 4 Keep air vents clear Blocked air vents may cause overheating and product damage. Clean vents with a soft brush as needed. 5 Inspect the cylinders Check the scarifying cylinder and raking cylinder regularly. Replace cylinders if worn, blunt, damaged, or causing excessive vibration. 6 Dry the collection bag before storing Clean the thatch collection bag after use and let it dry thoroughly before storage to help prevent mildew. 7 Battery off-season storage Unplug the charger and remove the battery packs when not in use. Recharge the batteries every 6 months to about 50% capacity during off-season storage. Troubleshooting Guide Remove both batteries before inspecting, cleaning, adjusting, or performing maintenance.
