3. When the mast of the drilling rig is raised and lowered, the operator should stand in a safe position.


4. When starting the motor, all friction clutches of the drilling rig should be opened.


5. When the drilling rig is working, it is strictly forbidden to remove the protective cover.


6. Before the work starts, the reliability of the braking device, as well as the working performance of the friction clutch and starting device should be checked.


7. Before the motor stops, it is forbidden to check the drilling rig.


8. When the drilling rig is working, it is strictly forbidden to fasten any parts of the drilling rig.


9. When the rig is running, it is strictly forbidden to refuel. Refueling of the upper mast pulley should be done when the rig is stopped.


10. Before the motor stops, it is not allowed to work on the mast.


11. Under any circumstances, when someone is working on the upper part of the mast, no other personnel are allowed to stay under the mast.


12. In case of bad weather (heavy rain, heavy snow, icing or strong winds above level 5), it is not allowed to work on the mast. At the same time, working on the mast with artificial lighting is also not allowed.


13. It is strictly forbidden to use wire rope with split strands.


14. It is strictly forbidden to touch the wire rope by hand when the drilling tool is lifted and lowered.


15. Except for lifting the drilling rig and lowering the drilling pipe, it is strictly forbidden to open the wellhead.


16. In order to prevent the drilling tool or the pumping cylinder from shaking when it is taken out of the well, it must be hooked with a hook made of a steel rod with a diameter of 15-20 mm.


17. When cleaning the drawer, a sturdy and reliable steel wire rope should be used to form a loop, cover the lower end of the drawer, and turn it upside down.


18. All workers should leave the well when the casing is lifted or lowered with the tackle, and when the machine is in salvage work.


19. When pulling out the casing with a jack, in order to prevent the casing from falling off, it must be fixed to each other.


20. Drilling should be stopped when lighting is stopped (at night). At this time, when the drilling tool is still in the well, the drilling tool should be carefully removed from the well.
