First, the preservation of drill rods:

　　1: Make sure to remove internal water and properly lubricate.

　　2. The outside of the drill rod, including the thread, should be wiped clean. At the same time, lubricate the male and female joints and add rubber caps. Rubber boots are small and inexpensive but further protect the drill rod.

　　Then, save the impactor:

　　1. Short-term storage:

　　(1) Remove the water inside and outside the impactor;

　　(2) Add 1 liter of calf oil from the upper joint part;

　　(3) Let the wind blow for about 10 seconds to fully lubricate the internal parts;

　　(4) Cover the upper and lower joints with rubber sleeves respectively.

　　(5) Place it horizontally in a dry environment.

　　(6) If stored for a long time, disassemble the striker and properly lubricate all parts, then assemble the striker and proceed to the fourth and fifth steps.

　　2. Re-enable

　　(1) Disassemble the impactor and check all parts. If any fault is found, please repair or replace it in time. If used without testing, it may shorten the life of the drill pipe.

　　(2) Clean all parts, clean and lubricate properly.

　　(3) After the drill pipe is assembled and confirmed to be correct, it can be put into use.

　　Many people might think it's more than just a shocker, because of the limited conditions in the mine, it's usually casually dropped and still used. But why are the profits of projects with similar conditions so different? A large part of the reason may be the management of equipment and drill consumables. Careful management and maintenance can definitely save a lot of money. Record the wear of the drilling tool. For example, the impactor has been used for several months, compare, make adjustments, store the drill pipe as recommended, and strictly follow the requirements for reasonable maintenance and lubrication.
