<p>The pneumatic installation tool, such as a screwdriver or nut applicator (1), operates with compressed air and has a disconnection mechanism functioning when a specific torque value is reached. When there is compressed air feed in the supply conduit (3) to the installation tool this is registered by an indicator (2) in the start handle grip of the tool, showing whether the tool is being used or in a rest situation. When the tool is switched off at the specific torque value, the compressed air flow in the feed conduit is stopped and the air movement indicator is no longer acive, whilst the start handle grip is still activated. This situation with the air movement indicator not active and the start handle grip (11) indicator is active can exclusively appertain when the installation tool is switched off at the specific torque value.</p> |
