Battery Charging Remove the battery Press the push lock button on the battery and pull the battery pack out of the saw. Connect the charger Confirm the charger voltage matches the outlet. Plug the charger adapter into an AC outlet, then connect the charger plug to the battery charge socket. Watch the charging indicator The 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 charging A full charge takes about 5–6 hours. Unplug the charger from the outlet first, then disconnect it from the battery. 05Battery indicator: 1 light means 25%, 2 lights mean 50%, 3 lights mean 75%, and 4 lights mean 100% charge. Chain Oil & Lubrication Use bar and chain oil only Use 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 use Remove the oil tank cap and add oil to about 1 cm from the rim of the filler. Oil during operation Press the clear oil pump 2–3 times after the saw has been used for 5–8 minutes. Check oil delivery With the bar and chain installed, start the saw and confirm oil is being delivered to the chain before continuing work. CAUTIONNever run the saw without lubrication. Failure to lubricate the chain can damage the bar, chain, and oiler system. Adjusting Chain Tension STOPRemove 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 cover Make 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 chain Turn 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 cover Use the wrench to tighten the cover nut clockwise, then confirm the chain is still properly seated in the guide bar groove. Getting Started Complete the daily checklist Inspect the chain, guide bar, motor housing, screws, ventilation slots, safety lock button, and On/Off switch before each work session. Secure the workpiece Clamp loose wood when possible. Do not hold the workpiece with your hand or foot while cutting. Insert the battery Slide the battery into the compartment until it clicks securely into place. Start the saw Make 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 work Allow the chain to reach full speed before entering the cut. Use light downward pressure and keep the saw running through the cut. Stop safely Release 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. STOPDo 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. CAUTIONRestart reminder: Wait at least 5 seconds after stopping before restarting. Repeated rapid starts can generate heat and damage the motor. Cutting Tips 1 Cut wood only Do not use the saw to cut plastic, masonry, metal, non-wood building materials, vines, or small underbrush. 2 Stay within capacity The saw is designed for limbs and smaller logs up to 5 inches in diameter, depending on wood type. 3 Watch for spring back Use caution when cutting limbs under tension. Spring-loaded wood can move suddenly when released. 4 Avoid kickback Do not let the guide bar tip contact any object. Keep a firm grip with your thumb and fingers wrapped around the handle. 5 Break in new chains After 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 STOPAlways 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. 1 Clean after each use Use a cloth, paintbrush, or brush to remove dust and wood splinters. Keep ventilation slots free from sawdust and debris. 2 Clean the sprocket area Use a brush or compressed air to clean the sprocket area. Do not allow liquid inside the motor housing. 3 Check chain tension often Chains stretch during use, especially during the first period of use or after replacement. Never work with a loose chain. 4 Inspect the guide bar Replace 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. 5 Inspect the sprocket Replace 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. 6 Store safely Install the guide bar cover and store the saw indoors in a dry, high, or locked place out of children’s reach.
