Plug the charger adapter into an AC outlet, then connect the charger plug to the battery charge socket.Watch the charging indicatorThe charger light turns red while charging and green when fully charged. The battery indicator LEDs blink and illuminate one by one during charging.Unplug after chargingA full charge takes about 5–6 hours. Unplug the charger from the outlet first, then disconnect it from the battery.🔋 Battery indicator: 1 light means 25%, 2 lights mean 50%, 3 lights mean 75%, and 4 lights mean 100% charge.Chain Oil & LubricationUse bar and chain oil onlyUse good-quality bar and chain oil designed for chain saws. Do not use engine oil, mineral oil, contaminated oil, or low-quality oil.Fill before useRemove the oil tank cap and add oil to about 1 cm from the rim of the filler.Oil during operationPress the clear oil pump 2–3 times after the saw has been used for 5–8 minutes.Check oil deliveryWith the bar and chain installed, start the saw and confirm oil is being delivered to the chain before continuing work.⚠️ Never run the saw without lubrication. Failure to lubricate the chain can damage the bar, chain, and oiler system.Adjusting Chain Tension🚫 Remove the battery and wear protective gloves before touching the bar or chain. The chain is sharp even when the saw is off.Loosen the end coverMake sure the saw is shut off and the battery is removed. Loosen the chain/sprocket end cover slightly by turning the end cover knob counterclockwise.Adjust the chainTurn the cover screw until there is only about a 0.3 cm gap when pulling the chain. The chain should be snug but still able to rotate by hand without binding.Tighten the coverUse the wrench to tighten the cover nut clockwise, then confirm the chain is still properly seated in the guide bar groove.Getting StartedComplete the daily checklistInspect the chain, guide bar, motor housing, screws, ventilation slots, safety lock button, and On/Off switch before each work session.Secure the workpieceClamp loose wood when possible. Do not hold the workpiece with your hand or foot while cutting.Insert the batterySlide the battery into the compartment until it clicks securely into place.Start the sawMake sure the chain is not touching anything. Hold the saw firmly, press the safety lock button, then squeeze the On/Off switch.Let the chain do the workAllow the chain to reach full speed before entering the cut. Use light downward pressure and keep the saw running through the cut.Stop safelyRelease the On/Off switch and wait for the chain to stop completely before removing the saw from the cut, setting it down, or inspecting it.🚫 Do not use this saw in a tree, on a ladder, on a scaffold, in wet conditions, near electrical wires, or above shoulder height. This saw is not intended for tree felling.⚠️ Restart reminder: Wait at least 5 seconds after stopping before restarting. Repeated rapid starts can generate heat and damage the motor.Cutting Tips1Cut wood onlyDo not use the saw to cut plastic, masonry, metal, non-wood building materials, vines, or small underbrush.2Stay within capacityThe saw is designed for limbs and smaller logs up to 5 inches in diameter, depending on wood type.3Watch for spring backUse caution when cutting limbs under tension. Spring-loaded wood can move suddenly when released.4Avoid kickbackDo not let the guide bar tip contact any object. Keep a firm grip with your thumb and fingers wrapped around the handle.5Break in new chainsAfter installing a new chain, run the saw idle for about 5 minutes, remove the battery, recheck tension, then make only easy cuts for about 30 minutes.Maintenance & Care🚫 Always remove the battery before cleaning, checking, adjusting, servicing, or storing the saw. Let the saw cool for at least 5 minutes before servicing or storage.1Clean after each useUse a cloth, paintbrush, or brush to remove dust and wood splinters. Keep ventilation slots free from sawdust and debris.2Clean the sprocket areaUse a brush or compressed air to clean the sprocket area. Do not allow liquid inside the motor housing.3Check chain tension oftenChains stretch during use, especially during the first period of use or after replacement. Never work with a loose chain.4Inspect the guide barReplace the guide bar if it is bent, cracked, broken, has spread rails, or has wear inside the rails that allows the chain to lay sideways.5Inspect the sprocketReplace the sprocket when wear exceeds 0.5 mm. Do not mount a new chain on a worn sprocket or a worn chain on a new sprocket.6Store safelyInstall the guide bar cover and store the saw indoors in a dry, high, or locked place out of children’s reach.Troubleshooting GuideRemove the battery before inspecting, cleaning, adjusting, or performing maintenance.
