Pneumatic manual and portable machine percussion were first developed in the 30s of the 20th century. Since these machines have not undergone major changes in the technical specifications and operating principle. In its work, pneumatic manual and portable machines require considerable effort supply, emit high levels of vibration and handles big noise in the workplace, many times higher than the permissible limits. This leads to serious occupational diseases workers. Numerous attempts to reduce the necessary feed force and vibration handles by optimizing work processes have not led to positive results. To solve these problems, the author analyzes the dynamics of the housing movement, the piston - drummer and working tool, resulting in a proposed new operating principle of this type of pneumatic machines that seeks to kinematic connection between the piston - drummer and working tool.1
