# Prerequisites at Start-up

- All electrical components (tightening controller, power supplies, etc.) must warm up to a room temperature of 20°C in, order to avoid damage from condensation.

- Ensure that the control unit for the tool is integrated properly with the power supply and the overall facility so that notices and signals can be properly dealt with.

- Inspect all electrical cables, connectors, powers, pneumatic and mechanical are properly connected.

- Clean and lubricate all parts of the equipment according to maintenance schedule before operating.

- Inspect equipment for any damage.

- Before start up, the operator of the station must be trained on the working station. Training the operator is the responsibility of the plant owner. We strongly recommend requesting Atlas Copco to perform this training with the operator.

## Before Start-up

Before start-up of the equipment, the following process must be executed:

1. Ensure arm is positioned on parking hook.

2. Ensure all pneumatic components and hoses are connected properly.

3. Ensure controller system is powered on.

4. Open air supply lock-out valve to pressurize the system.

5. After connecting the equipment to the main air supply, verify the inlet pressure on the pressure gauge, located at the air regulator. Ensure that the pressure is set to the minimum required. If the minimum pressure is not achieved, check the main air supply.

6. Adjust the balance of the arm. The precision regulator can be configured by using the adjustment knob. Increase or decrease the pressure until the arm is in desired position. The force to raise and lower should be approximately the same. Ensure to tighten the lock nut, located on knob stem, after pressure adjustment.

7. Follow the Pilot Operated Check Valve setup procedure, to prevent the parallel arm segment from falling downward in case of a sudden loss of air.

8. Verify that the inductive sensor distance is 1.3 mm. (sensor is located on the brake).

9. Perform a functional test of the brake.

10. Perform a functional test of the emergency stop.
