6. Usage Instructions

1. Battery installation: Push the fully charged lithium battery pack into the bottom slot of the device, hearing a click sound indicates the battery is securely locked; to remove it, hold the side clip and pull the battery downward.
2. Grinding wheel installation: Shut down the machine and remove power, install the protective cover, place the grinding wheel on the output shaft, tighten the pressing plate, and ensure the grinding wheel is secure with no looseness or eccentric movement.
3. Shield adjustment: Loosen the shield fixing screws, rotate the shield to the appropriate protection angle, and tighten the screws for fixation.
4. Auxiliary handle installation: screw the side auxiliary handle into the threaded hole on the body, tighten it securely. For heavy-duty operations, it is recommended to add a dual-hand operation with a side handle.
5. Power-on procedure: Ensure all components are securely installed, then press the switch to start the machine; wait until the grinding wheel reaches the rated speed before engaging with the workpiece for processing.
6. Task operation: Move the machine at a steady, uniform speed. Do not apply excessive pressure on the grinding wheel; maintain a smooth cutting and polishing process to prevent the grinding wheel from getting stuck.
7. Assignment completed: Release the switch, wait for the grinding wheel to stop completely, remove the battery and store it; clean the machine surface of dust.

7. Precautions

1. Students must wear goggles and protective gloves; it is recommended to wear a dust mask. Loose clothing and jewelry are strictly prohibited to prevent getting caught by the rotating grinding wheel.
2. The protective shield for homework tasks cannot be removed; the angle grinder is prohibited from being used without a shield to prevent debris from splashing and causing injury.
3. The grinding wheel blades must not be used when they have cracks, defects, or deformation; use grinding wheel blades of matching specifications that meet quality standards.
4. Tool operating status: Do not touch the rotating grinding wheel. It must be completely stopped before adjusting the components.
5. Lithium batteries should be kept away from high-temperature sources and open flames. It is prohibited to puncture the battery pack; when not in use, remove the batteries and store them in a cool and dry place to prevent water ingress and moisture.
6. During prolonged continuous operation, the body shell becomes significantly hot. It is necessary to stop the machine and let it cool down to prevent the motor from overheating and being damaged.
7. Tools must not be used in humid or rainy conditions to prevent electric leakage risks.
8. The equipment must be placed in a location inaccessible to children, and children are prohibited from operating the machine.
9. If the grinding wheel shakes or there is abnormal noise from the machine body, it must be stopped immediately. Work can only resume after the fault is identified and repaired.
