Usage And Maintenance Skills Of Electric Lithium Electric Saw

--- The electric lithium chainsaw is one of the most widely used and frequently applied power tools in garden machinery. As it features extremely sharp saw teeth and is used for high-speed wood cutting, strict safety precautions must be taken during operation. We have summarized a series of operating methods, maintenance tips and precautions for electric lithium chainsaws and share them with you. ### 1. Use Proper and Reliable Lubricating Oil It is recommended to use high-quality, low-pollution lubricating oil for saw chains and guide bars, such as oil with strong anti-aging properties and rapid biodegradability. Oil with poor anti-aging performance tends to resinify and form hard deposits that are difficult to remove, especially on saw chain drive parts, around the clutch and on the saw chain. In severe cases, it may block the oil pump. In addition, **waste oil must not be used**. Waste oil does not provide the required lubrication, repeated contact may cause skin cancer, and it will also damage the environment. ### 2. Always Keep the Saw Chain Lubricated Lubrication of the saw chain and guide bar is extremely important for the use of an electric lithium chainsaw. Technicians state that a small amount of oil should always be thrown off the saw chain, and the tool must never be operated without lubrication. If the saw chain runs dry, the cutting parts will quickly be damaged beyond repair. Therefore, always check the lubrication of the saw chain and the oil level in the tank before starting work. ### 3. Regularly Check the Tension of the Saw Chain A new saw chain needs to be tensioned more frequently than one that has been in use for a long time. Generally, when the machine is cold, the saw chain is correctly tensioned if it engages on the underside of the guide bar but can still be pulled by hand along the guide bar. After reaching operating temperature, the saw chain expands and becomes loose. The drive links on the underside of the guide bar must not come out of the guide groove, otherwise the saw chain may come off. Retension the saw chain if necessary. As it cools down, the saw chain contracts. The chain must be slackened at this point, otherwise the crankshaft and bearings will be damaged. KEREPU electric lithium chainsaws are equipped with high-quality parts and imported Oregon saw chains, which greatly reduce saw chain damage and extend the service life of the chainsaw. ### 4. Important Details Not to Be Ignored Users should pay special attention to the following operating details when using an electric lithium chainsaw. First, do not pull the starter rope all the way out when starting the chainsaw. Gently pull the starter handle until it reaches the stop position, then pull it quickly and firmly while pressing down on the front handle. Second, after the motor has been running at full throttle for a long time, allow it to idle for a period to cool the airflow and release most of the heat from the motor. This prevents thermal overload of components mounted on the motor, such as the ignition system and controller. Third, if the motor power drops significantly, the air filter may be dirty. Remove the controller cover, take out the air filter, clean dirt around it, separate the two parts of the filter, dust it with your palm, or blow it clean from the inside out with compressed air. When refitting the air filter, remember to check that the choke and torsion spring are in the correct positions. ### 5. Timely and Thorough Later Maintenance The most important part of electric lithium chainsaw maintenance is the saw chain. A properly maintained and sharpened saw chain can cut into wood easily with very little pressure. During daily maintenance, check for cracks and broken rivets on the saw chain links. Replace any damaged or worn parts on the saw chain with new parts of the same shape and size. Carbide saw chains are particularly wear-resistant. For long-term storage of the electric lithium chainsaw, remove the battery and store it properly in a well-ventilated area, and clean the entire machine. Perform maintenance only after the motor has completely stopped and cooled down to avoid burns from hot components. Remove the saw chain and guide bar, clean them, and spray with anti-rust oil. Thoroughly clean the machine, especially the motor cooling fins and the air filter. Finally, everyone understands the importance of proper operation of an electric lithium chainsaw, but the key is to put it into practice. Any non-standard operation or delayed maintenance may lead to potential safety hazards. ---
