2.7. Inspect the workplace, remove objects that interfere with the work and clear the passages.
2.8. Make sure that the workplace is adequately lit. When using a portable light bulb, check that the lamp has a protective net, that the cord and the insulating rubber tube are working properly.
2.9. At each delivery of the pneumatic tool, the completeness and reliability of the fastening of the parts should be checked, as well as an external inspection to check the serviceability of the cable (cord), its protective tube and plug.
2.10. Before working with pneumatic tools, you should check:
– reliability of tightening of all threaded joints;
– the absence of damage to the rubber air hoses, the reliability of their fastening on the fitting (the fittings have serviceable edges and threads, providing a strong and tight connection of the hose to the pneumatic tool and to the air line);
– the strength of the connection of the hoses to the pneumatic tool and the connection of the hoses to each other, carried out only with the help of fittings or nipples with a working thread (ring grooves) and coupling clamps;
– it is not allowed to use wire and electric wire for fixing hoses to fittings or nipples in order to avoid hose breakage;
– the correctness of the sharpening of the insert tool (drills, screwdrivers, wrenches, countersinks, etc.), the absence of cracks, potholes, burrs and other defects on it;
– the shanks must be smooth, without bevels, cracks and other damage, tightly fitted and properly centered;
– the presence on the shank of the plug-in tool percussion (chisels, crimping, etc.) of clear edges and the possibility of its entry into the axle box of the hammer;
– placement of a set of insertion tools during storage in a portable box;
– the quality of compressed air supplied to the tool, which must have a purity of at least grade 5;
– the presence of lubrication of the pneumatic tool, the absence of cracks and other damage on its body;
– ease and speed of opening and closing the valve to turn on the tool, the absence of air passage in the closed position;
– the absence of nicks on the cone of the spindle of the drilling machine;
– the reliability of the fencing of the abrasive wheel on the grinding machine with a protective casing;

2.16. When preparing the wrench for operation, you should install a shock absorber, pick up an interchangeable head-wrench on a screwed nut or bolt and, using a pin with a lock ring, attach it to the wrench. Then it is necessary to establish the necessary tightening torque of the nut and bolt, for which purpose turn the throttle until the corresponding number appears in the reverse slot, as well as the necessary direction of rotation of the interchangeable key head.
