1、 The operator must be familiar with the operation sequence and performance of the machine tool, and it is strictly prohibited to use equipment beyond its performance limit. At the same time, the operation must be carried out under the guidance of the guiding personnel, and the machine tool cannot be operated alone without permission.

2、 Preparation and precautions for surface grinding machine before operation
1. Before operation, it is necessary to wear work clothes and protective equipment to prevent clothing, hair, and other items from being caught by the grinding wheel.
2. Before starting up, according to the equipment lubrication requirements, check whether the lubricating oil and working fluid level of the machine tool meet the requirements, and add oil if necessary.
3. Grinding machines must use specialized grinding wheels and are not allowed to replace ordinary grinding wheels. Before starting work, check that the grinding wheel and wheel cover are intact without cracks, installed correctly, and securely fastened. Machine tools without grinding wheel covers are not allowed to operate. Before installing a new grinding wheel, it should be checked for cracks and gaps. If there are cracks or scars, use is strictly prohibited.
4. The machine tool should be clean, and the flat workpiece should have a reference surface. If there are flying spikes, they should be removed and filed flat.
5. Do not grind thin iron plates. Do not use a grinding wheel to grind the end face of the workpiece.   
6. Check that all handles, gears, switches, knobs, etc. of the machine tool are in their original or desired positions.

3、 Operation of surface grinder
1. When placing the workpiece, the magnetic disk must be wiped clean. Workpieces that are ground high or have a small contact area are not easily attracted by magnetic force, and appropriate height blocks must be added to check if they are firmly attracted.   
2. Before grinding, raise the grinding wheel and turn on the magnetic disc switch. Check that the workpiece on the magnetic disc is firmly attached before grinding. The workpiece should be tightly padded.   
3. Before driving, check whether the grinding wheel is intact and whether the motor switch is intact. After driving, observe for 1-2 minutes until the grinding wheel rotates smoothly before starting to work.
4. When the grinding wheel approaches the workpiece, it is important to carefully observe for any protrusions or indentations. When the grinding wheel quickly approaches the workpiece, hand cranking should be used instead. Manual grinding head lifting, lateral movement, workbench, adjust gear switch.   
5. When the machine is in operation, it is strictly prohibited to touch the workpiece and grinding wheel with hands or handheld tools to prevent hand injuries. Before and after grinding, ensure that the protective barrier is in place and do not touch the grinding surface with your hands.
6. During the operation of the machine tool, it is not allowed to draw cutting fluid from the water tank. When the grinding wheel is not completely stationary, it is not allowed to clean the coolant, debris or replace the workpiece.
7. When loading and unloading workpieces, the grinding wheel must be raised to a certain position before proceeding.

4、 After the operation is completed
1. At the end of the work, stop the machine as required, unplug the plug and cut off the power supply. Use specialized tools to clean the iron filings on the surface of the workbench and maintain the cleanliness of the site.   
2. Fill in the equipment daily maintenance form and equipment maintenance record form.
