Usage Precautions of Power Tool Motor Magnet




1. After heating, the magnetic properties will be greatly reduced. Please refer to the catalog or the relevant temperature characteristic pointer, and be careful not to overheat the magnet when assembling or using it.
2. When using or storing magnets, please avoid environments containing corrosive gases, high conductivity (such as water containing electrolytes, etc.), acidic environments, organic solvents, etc. Otherwise, it will cause corrosion of magnets and weakening of magnetic properties and mechanical strength. For heat resistance and other conditions, please refer to the catalog or other data. For related issues, please consult with Jiadao Company.
3. The magnet is hard and brittle, so when it is used in places with vibration and impact, it may break or fall off. If it is used for this purpose, please pay attention to the design, even if the magnet is broken, it will not fall off.
4. It is a high-speed running body, so objects may be broken. When designing, please take necessary precautions so that if it breaks, the fragments will not fly out.
5. The magnetism of NdFeB is very strong, and the hands or other parts of the body should be avoided to be caught during the operation. For larger sizes, more attention should be paid to personal safety and protection.
6. Do not put the magnet close to the magnetic steel of electronic medical equipment or people carrying medical equipment such as pacemakers.
7. Do not swallow the magnet. If accidentally swallowed, please go to the hospital for treatment immediately. Keep magnets out of reach of children.
8. During use, ensure that the workplace is clean, and that special-shaped magnets are used to prevent small impurities such as iron filings from being adsorbed on the surface and affecting the normal use of the product.
9. The magnetism is very strong. If there is a strong impact on it, the magnet will be broken and scattered, and the magnetic fragments may fly into the eyes. Please use it carefully.

Step 1 - Inspect the Motor.
Step 2 - Prepare the Motor shaft and remove any protective covering or coating.
Step 3 - Back out the set screws on the Drive Magnet to make sure they will not interfere.
Step 4 - Apply grease to the Motor shaft of the Front Casing and the Rear Casing.
Step 5 - Align and slide the Drive Magnet onto the Motor shaft into position
Step 6 - Tighten the set screws on the Drive Magnet. If the Bracket has been installed, tighten the set screws through the hole at the bottom of the Bracket.
Step 7 - Clean the magnets with a piece of tape to remove all metal debris.
