Hand-held woodworker orbital sander

The correct use of manual sander.

First, the basic structure and principle of manual sanding machine

Manual sander is a commonly used hand-held power tool, usually composed of a motor, power switch, grinding disc, sandpaper disc and other components. The principle is to use the motor to drive the grinding disk to rotate, and rub the surface of the workpiece through the sandpaper on the sandpaper disk, so as to achieve the grinding, polishing and surface dirt removal of the workpiece.

Second, the correct use of manual sanding machine

1. Preparation: First of all, wear gloves and masks, choose the appropriate type of sandpaper, and plug the power plug into the power socket.

2. Assemble sandpaper: Fix the sandpaper on the sandpaper tray, ensure that the sandpaper is smooth and firm, and do not use excessive wear sandpaper.

3. Adjust the speed: Adjust the speed of the manual sander as needed to ensure the best friction between the sandpaper and the workpiece.

4. Sanding operation: Place the manual sander on the surface of the workpiece, press the power switch, move the sander back and forth along the surface of the workpiece, and grind out a flat surface.

5. Cleaning tools: After using the manual sander, the sandpaper disk and grinding disk should be thoroughly cleaned, and the motor and fuselage should be kept clean.

Three, manual sander precautions

1. Safe operation: When operating the manual sander, be sure to pay attention to safety and keep a clear mind to avoid the grinding disc and sandpaper falling off during use and causing danger.

2. Scope of application: Manual sanding machine is suitable for the processing and grinding and polishing of metal, tile, wood, glass and other materials, not for the processing of hard materials such as concrete.

3. Maintenance and repair: Pay attention to maintenance and repair during use, regularly replace the sandpaper, and keep the fuselage clean to extend the service life of the manual sander.

The above is the basic structure and principle of the manual sander, as well as the correct use and precautions. When using a manual sander, be sure to pay attention to safety, choose a reasonable sandpaper type and speed, and follow the correct sanding operation method to obtain the best grinding effect.
