How to replace and maintain the blade of a lithium cordless circular saw?

1. Steps to replace the blade
Power off and check:
Before replacing the blade of a lithium cordless circular saw, be sure to turn off the power of the lithium cordless circular saw and unplug the battery to ensure safety.
Check whether the blade fixing screw and locking device are intact to avoid accidents during the replacement process.
Remove the old blade:
Use a suitable tool (such as a wrench or screwdriver) to loosen the blade fixing screw.
Carefully remove the old blade from the circular saw, taking care to avoid the blade from scratching your fingers or damaging other parts.
Install the new blade:
Place the new blade on the circular saw in the correct direction (the teeth should face the cutting direction).
Use the fixing screw to lock the new blade on the circular saw, making sure the screw is tightened in place to prevent the blade from loosening.
Inspection and testing:
After installing the new blade, carefully check whether the blade is firmly installed and make sure it is not loose or skewed.
Reinstall the battery, turn on the power, and perform an idling test to check whether the blade runs smoothly without abnormal sounds.

2. Blade maintenance method
Regular cleaning:
After each use, clean the sawdust, dust and other debris on the blade in time to avoid affecting the cutting effect and blade life.
Use a soft cloth or brush to gently wipe the blade, and avoid using hard objects or metal brushes and other tools that may scratch the blade.
Lubrication maintenance:
Regularly apply an appropriate amount of lubricating oil to the blade bearings and transmission parts to reduce friction and wear and improve the smoothness of the blade operation.
Check the wear:
Regularly check the wear of the blade. If the blade teeth are found to be blunt or notched, replace the new blade in time.
Avoid using excessively worn blades to avoid affecting the cutting effect and safety.
Storage precautions:
When not in use, the lithium cordless circular saw should be stored in a dry, ventilated, non-corrosive gas environment.
Avoid exposing the blade to a humid or high temperature environment for a long time to prevent the blade from rusting or deforming.
