Using the CSE12 Electric Chain Saw is straightforward. First, make sure you choose the right voltage option (110V or 220V) according to your power supply. Connect the saw to the power source. If you've bought the separate chain and bar, install them properly before starting. When cutting, use the built - in levels to ensure accurate alignment. The LED load indicator will show you if you're cutting at maximum efficiency. Remember to handle the saw with care. Keep it away from water and dust as much as possible, thanks to its waterproof and dustproof switch, but still don't expose it to extreme conditions. The saw has electronic overload and thermal protection, but don't overwork it for long periods. For maintenance, regularly check the chain tension and sharpness. Clean the saw after each use to keep it in good condition. If you notice any problems, stop using the saw and get it checked by a professional.
