Definitions

• the preceding equipment level is 10 ⁇ of bullets, as there is a live solution, drilling is carried out when the appliance is turned off.
• the reliability of the work of a light bullet depends on the reliability of the transmission of a short-circuit to the disruptive tool of the outdoor-rocket. This reliability in various operations is ensured by various ways.
• a drill has been known to contain an external pipe, an internal pipe and a detachable cat shell ( ⁇ 5 ⁇ d ⁇ 3692126). On the outside of the outdoor pipe, an internal 20-side discharge was made.
