Installation

Installation Requirements

Air quality

Poor air quality may cause damage to the tool and reduce the performance.

  • 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. Install the filter as close as possible to the product and prior to any other air preparation units to avoid pressure drop.

  • Lubrication free tools are a better choice from an environmental perspective.

  • Lubrication will shorten the life time of the turbine motor and once lubricated, you will need to continue with the lubrication.

Compressed Air Connection

WARNING

Risk of severe injury

Air under pressure can cause injury.

  • Always shut off the air supply when not in use or before any adjustments.

  • Drain the hose of air pressure and disconnect the tool from air supply when not in use or before any adjustments.

  • Always use the correct hose size and air pressure for the tool.

WARNING

Compressed Air

High air pressure can cause severe damage and bodily injury.

  • Do not exceed maximum air pressure.

  • Make sure that there are no damaged or loose hoses or fittings.

For correct air pressure and hose size, see the Technical Product Data on - https://servaid.atlascopco.com or www.atlascopco.com.

Make sure that the hose and couplings are clean and free from dust before connecting to the tool.

Operation

Ergonomic Guidelines

Consider your workstation as you read through this list of general ergonomic guidelines to identify areas for improvement in posture, component placement, or work environment.

  • Take frequent breaks and change work positions frequently.

  • Adapt the workstation area to your needs and the work task.

    • Adjust for a convenient reach range by determining where parts and tools need to be located to avoid static load.

    • Use workstation equipment such as tables and chairs appropriate for the work task.

  • Avoid work positions above shoulder level or with static holding during assembly operations.

    • When working above shoulder level, reduce the load on the static muscles by lowering the weight of the tool, using for example torque arms, hose reels or weight balancers. You can also reduce the load on the static muscles by holding the tool close to the body.

    • Take frequent breaks.

    • Avoid extreme arm or wrist postures, particularly during operations requiring a degree of force.

  • Adjust for a convenient field of vision that requires minimal eye and head movements.

  • Use appropriate lighting for the work task.

  • Select the appropriate tool for the work task.

  • In noisy environments, use ear protection equipment.

  • Use high-quality inserted tools and consumables to minimize exposure to excessive levels of vibration.

  • Minimize exposure to reaction forces.

    • When cutting:

      A cut-off wheel can get stuck if the cut-off wheel is bent or not guided properly. Use the correct flange for the cut-off wheel and avoid bending the cut-off wheel during operation.

    • When drilling:

      The drill might stall when the drill bit breaks through. Use support handles if the stall torque is high. The safety standard ISO11148 part 3 recommends using a device to absorb a reaction torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.

    • When using direct-driven screwdrivers or nutrunners:

      Reaction forces depend on the tool settings and joint characteristics. Strength and posture determine the amount of reaction force that an operator can tolerate. Adapt the torque setting to the operator's strength and posture and use a torque arm or reaction bar if the torque is too high.

  • In dusty environments, use a dust extraction system or wear a mouth protection mask.
