1. Equipment use of personnel must be trained, must be approved by the director, and use in accord with the rules and regulations, not the company staff must be approved by the chief engineer rear can use. 

2. Fully prepared, before starting the cleaning wipes platform and guide rail, if confirmed no obstacle. 

3. Observe whether digital display is normal after boot, general casting measurement principle, don't open the computer, special type need to measure the irregular line shall specify professional personnel to open the computer system and check the boot is normal, open the measuring software is rapidly into the corresponding interface. 

4. In the fast moving axis, should use the handwheel, but not directly stimulating columns, sliding sleeve and smoked pull cantilever, it will cause body deformation, surface reduce the accuracy of measurement. 

5. As measured by measuring head must along the direction of the stylus movement, measuring the hair immediately after reset, measuring point can not drastic collision, lest cause damage of measuring head and the measuring precision of the "slow light touch" is the principle of measuring technique. 

6. Rotate the scriber, want to let nature take its course, and shall not use brute force, in order to avoid the scriber deformation, increase the laying-out error; Line according to the workpiece surface convex concave situation, adjust the position of the cantilever keep scriber contact with the workpiece surface at the same level; When scribing head change the direction of rotation to turn pull up dowel pin, then turn the line head, put in place, unscrew the positioning pin, a micro underline head positioning pin into the slot. 

7. Stop before departure, should check whether the equipment of power are closed, and close to close with gear. Check whether the spare parts in good condition, work out every day, will come to needle removed away. If you have lost, to examine the related personnel.

3. Preventive maintenance and

1. The ruling machine equipment and crossed the platform must do daily maintenance, maintenance. Each part of the daily maintenance should be around with no dust and grease, dirt, debris wipes platform and track, and track application clean soft cloth to wipe, weekly maintenance should be a week on the guide rail lubricating oil (but with grating ruler or magnetic grating ruler guides surface oil, and pay attention to not make the pollution), check whether there is connection of different parts and other anomalies. 

2. To have abnormal situation and lack of parts quality minister to notice the damage and to find the related technical personnel inspection and maintenance.

3. The use of don't allow anyone to trample, collision orbit plane and accessory. 

4. When lifting casting, the casting platform through above, it is strictly prohibited to avoid unexpected damage marker. 

5. Lifting casting upper and lower platform must have the specialist command, casting by the west or north in and out of the platform, only keep a collision to the ruling machine column and any other parts, it is strictly prohibited in the process of operation platform with large castings turn around. 

6. Orbit case anyone is forbidden to remove. 

7. The equipment downtime after measuring arm must be hit to the center of the platform, to prevent accidental collision.
