Two green lights will illuminate when the charger is powered.Insert the battery packsSlide both battery packs into the dual-port charger until they lock into position. Red lights indicate normal charging.Remove when chargedWhen 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 SettingsThe 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.PositionScarifying Depth15 mm2-0.5 mm3-6 mm4-8.5 mm5-9.5 mmPositionRaking / Dethatching Depth110 mm24.5 mm3-1 mm4-3.5 mm5-4.5 mm💡 Depth note: A negative depth means the tines or blades are working below the ground surface and penetrating the soil layer.Getting StartedPrepare the lawnMow 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 cylinderUse 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 depthTurn off the unit and remove both batteries before changing depth. Select the most suitable depth based on grass height and lawn condition.Install both batteriesOpen the battery compartment cover and insert both batteries until they click into place. Close the battery compartment cover.Start the unitPress 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 forwardPush the unit forward at a steady pace. Work in slightly overlapping rows to avoid missing areas.Stop safelyRelease 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. Raking1ScarifyingUse the 7-blade scarifying cylinder to scratch through and between the grass, remove unwanted material, and open the soil for better aeration.2Dethatching / RakingUse the 24-tine raking cylinder to scratch the surface of the lawn and pick up lighter debris for improved oxygen absorption, airing, and drainage.3Best operating patternWork in straight lines along one side of the lawn with slightly overlapping rows. Circle around flower beds and pay extra attention when changing direction.4Seasonal guidanceThe 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.5Raking frequencyThe 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 bagLift the ejector flap and remove the collection bag from the mounting hooks.Place the machine upside downPlace the unit on a flat, stable surface to access the underbody.Unlock the installed cylinderRemove the lock screw and open the cylinder lock that secures the scarifying cylinder.Remove the cylinderLift the installed cylinder up and remove it from the housing.Install the other cylinderInsert the replacement cylinder and press it into the holder. Refasten the cylinder lock and secure it with the lock screw.Return to operating positionPlace 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.1Keep hardware tightCheck that all nuts, bolts, screws, covers, and guards are secure and in safe working condition before use.2Empty the collection bag oftenEmpty the thatch collection bag frequently during use. The manual recommends emptying it when it is half full because a full bag reduces performance.3Clean with a brush or clothClean the machine with a brush or cloth. Do not use solvents or water to remove dirt.4Keep air vents clearBlocked air vents may cause overheating and product damage. Clean vents with a soft brush as needed.5Inspect the cylindersCheck the scarifying cylinder and raking cylinder regularly. Replace cylinders if worn, blunt, damaged, or causing excessive vibration.6Dry the collection bag before storingClean the thatch collection bag after use and let it dry thoroughly before storage to help prevent mildew.7Battery off-season storageUnplug 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 GuideRemove both batteries before inspecting, cleaning, adjusting, or performing maintenance.
