工作时必须戴好防护口罩(或防护面罩)及眼镜。

 工作前,应检查砂轮有无损坏,安全防护装置是否完好,通风除尘装置是否有效。

 安装时,应注意螺母的压紧程度,应压紧到砂轮运动时不产生滑动为易,有多个压紧螺丝钉时,应按对角顺序逐步均匀旋紧。

砂轮装好后,必须将防护罩重新装好,再进行试转。直的砂轮,应空转5 分钟。砂轮转动时,不允许有明显震动。

打磨抛光时,应先启动吸尘装置,握牢工件,用力不得过猛,不准用杠杆推压元件,严禁站在砂轮正面操作,以防砂轮破裂伤人。不是专门用于端面磨削的砂轮,禁止用端面进行打磨抛光。

使用手持电动砂轮机打磨抛光时,必须有牢固的防护罩和加设保护接零线,或配用漏电保护器,并遵守以下电动手砂轮安全操作规程。

两人以上同时打磨抛光工作时,不准同时在同一方向相对作业,防止发生意外。

工件之凹凸处应轻轻打磨抛光,不得用力过猛,不得磨工件之棱角,以防砂轮片破碎伤人。

工作完毕后,应切断电源,确认砂轮停转后,方可离开岗位。

Wear protective masks (or face shields) and glasses when working.

Before working, check whether the grinding wheel is damaged, whether the safety protection device is intact, and whether the ventilation and dust removal device is effective.

When installing, we should pay attention to the tightenth degree of the nut. It should be pressed tight to the movement of the grinding wheel, and it should not be easy to slide. When there are many compressing screws, it should be gradually tightened in the diagonal order.

After the wheel is installed, the protective cover must be re loaded and tested. The straight grinding wheel should be turned for 5 minutes. When the wheel is rotated, no obvious vibration is allowed.

When polishing and polishing, we should start the suction device first, hold the workpiece firmly, not be too hard, not to use the lever push element, strictly prohibit the operation of the wheel on the front of the grinding wheel, in order to prevent the grinding wheel from breaking the person. It is not a grinding wheel specially used for face grinding. It is forbidden to polish and polish with the end face.

The use of a hand-held electric grinder for polishing and polishing must have a solid protective cover and a protective zero line, or a leakage protector, and comply with the following safety operation rules for the electric hand grinding wheel.

When two or more people are polishing and polishing at the same time, they are not allowed to work in the same direction at the same time to prevent accidents.

The concave and convex parts of the workpiece should be lightly polished and polished. No sharp force must be exerting. The edges and corners of the workpiece should not be worn to prevent the grinding wheel from breaking and hurting people.

After the work is finished, the power shall be cut off before the wheel is stopped.
