Page 7: Installation
Air Quality ■ For optimum performance and maximum product life we recommend the use of compressed air with a maximum dew point of +10°C (50°F). We also recommend to install an Atlas Copco refrigeration type air dryer. ■ Use a separate air filter which removes solid particles larger than 30 microns and more than 90% of liquid water. -
Page 8: Operation
It is possible to connect the tool to a pressure monitoring equipment to monitor the tightening. The pres- sure signal from the tool (differential pressure over the motor) can be used to detect: ■ Missed fasteners ■ Trigger release before set torque is reached © Atlas Copco Industrial Technique AB - 9839 0664 01... -
