Service Overview

Service Recommendations

Preventive maintenance is recommended at regular intervals. See the detailed information on preventive maintenance. If the product is not working properly, take it out of service and inspect it.

If no detailed information about preventive maintenance is included, follow these general guidelines:

  • Clean appropriate parts accurately

  • Replace any defective or worn parts

Preventive maintenance

Daily maintenance: Visual inspection of all visible parts on the tool, including the reaction bar. Worn parts should be inspected thoroughly. If defects are found, the tool has to be repaired by qualified personel.

On a regular basis and when needed: make sure that the filter in the FRL unit is clean, the oil level is above minimum and no water is in the compressed air.

Environmental circumstances

Daily maintenance if needed.

All environments are different; take the time to learn what your environment is like, and build your maintenance on this knowledge.

When the tool is used in an environment with a large amount of water in the surroundings, special care has to be taken to keep the internal and external parts free from water during storage. If the tool is stored for a long time, it is recommended that the tool is disassembled and that internal/external parts are free from water. All parts should be re-greased and re-oiled, according to the instructions before storage.

When the tool is used in an environment with a lot of particles in the pressurized air system, make sure that the filter in the FRL unit is clean, as well as the filter in the silencer of the tool. Too many particles will change the performance of the tool.

The tool is intended for lubricated air, supplied by the FRL unit. Make sure that the oil level is above minimum levels on a regular basis.

Installation

Installation Requirements

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

For impulse/impact tools make sure to use lubricators adjusted for these tools. Regular lubricators will add too much oil and therefore decrease the tool performance due to too much oil in the motor.

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

Both lubricated and lubrication free products will benefit from a small quantity of oil supplied from a lubricator.

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.

Operating Instructions

Operating the tool with reaction bar

  1. Attach the tool to the application.

  2. WARNING

    Be aware that the reaction bar will turn in the opposite direction to the tool.

    By using the reverse lever, the tool can be operated in both clockwise and counter-clockwise directions.

  3. Make sure the tool is placed in the correct position on the work surface as described in the picture. The end surface of the reaction bar and the socket/nut must be aligned. Make sure that the foot of the reaction bar hits the center of the nut that takes the reaction force.

  4. WARNING

    Never put your hand on or close to the reaction bar while the tool is being used.

    Press the push button to start the tool.

  5. Continue pressing the push button while running down the nut. With pneumatic tools you can hear a sound, while the tool is running the nut down. When the sound decreases, release the push button to stop the tool. With electric tools the run down of the nut is controlled by the Power Focus.

 

Using the reaction bar

WARNING

Crushing Hazard

Check the rotational direction of the tool before start! A start in an unexpected rotational direction can cause bodily injury or property damage.

  • Make sure that the rotational direction of the tool is correct before starting the tool.

  • Keep your hands away from the reaction bar while using the tool.

Apply the reaction bar, opposite the direction of the drive of the product, before starting the product.

  • End plates: Make sure that they are not scored or scratched. If the scratches are shallow, polish with fine grinding paste against a face plate. Clean thoroughly.

  • Rotor: Make sure that the end faces do not have any marks or burrs. Make sure that the hexagon drive is not damaged.

  • Cylinder: Make sure that the bore is not scored or scratched. If the scratches are shallow, polish with a fine grinding cloth. Clean thoroughly.

Maintenance Instructions

Service Recommendations

Preventive maintenance is recommended at regular intervals. See the detailed information on preventive maintenance. If the product is not working properly, take it out of service and inspect it.

If no detailed information about preventive maintenance is included, follow these general guidelines:

  • Clean appropriate parts accurately

  • Replace any defective or worn parts

Preventive Maintenance

Preventive maintenance

Daily maintenance: Visual inspection of all visible parts on the tool, including the reaction bar. Worn parts should be inspected thoroughly. If defects are found, the tool has to be repaired by qualified personel.

On a regular basis and when needed: make sure that the filter in the FRL unit is clean, the oil level is above minimum and no water is in the compressed air.

Inspection of silencer

Change or clean the filters regularly. Clogged filters will reduce power output.

Tightening of threaded connections

The tightening torque indicated in the exploded views in ServAid (see Spare parts section in https://servaid.atlascopco.com) will give the right clamping force and prevent threaded joints from loosening.

Retightening to the correct torque is needed on a regular basis, depending on application and usage.

For joints secured with Loctite, apply new Loctite when retightening.

Service instructions

Overhaul and preventive maintenance are recommended at regular intervals at least once a year or after 5 000 tightening operations, whichever comes first. More frequent overhauls may be required if the machine is used in heavy-duty applications. If the machine fails to function correctly, it must be taken out of operation immediately for inspection.

The strainer at the air inlet must be cleaned regularly in order to prevent clogging due to contamination. The machine capacity will otherwise be reduced.

All parts must be cleaned thoroughly during overhaul work and defective or worn parts must be replaced.

It is important that the threaded connections on the machine are tightened properly, see the exploded views. Lubricate the threads with grease prior to fitting.

All O-rings must be greased prior to assembly.

Always use an Atlas Copco FRL-unit for regulation of pressure oil mist, water separation and filtering.

Lubrication Instructions

Rust Protection and Cleaning

Water in the compressed air can cause rust. To prevent rust we strongly recommend to install an air dryer.

Water and particles can cause sticking of vanes and valves. This can be prevented by installing an air filter close to the product to avoid pressure drop.

Before longer stand stills always protect your tool by adding a few drops of oil into the air inlet. Run the tool for 5–10 seconds and absorb any access oil at the air outlet in a cloth.

For maximum performance

It is important to lubricate regularly to get maximum performance and trouble-free operation.

Use lubricants of good quality. The oils and greases mentioned in the table are examples of lubricants which are recommended.

For Maximum Performance

At tough working conditions – soft joints and max. setting – lubrication of the air is recommended.

With extreme dry air the service life of vanes and machine performance might be reduced. A daily supply of 0.1 – 0.2 ml oil into the machine inlet will improve the machine performance. Alternatively consider an automatic lubricator device, Atlas Copco oil fog lubricator DIM, or single point lubricator DOS, which will improve the machine performance.

Troubleshooting

Troubleshooting

The table describes the most common problems, possible reasons and actions to troubleshoot them.

Problem

Possible reason

Action

Free speed is too slow, pressure never reaches the target.

Too low air flow in the pressurized air system.

Shorter hose to the FRL unit and larger diameter are needed. Check air flow for free speed in the specifications for the directions of required air flow at free speed.

The tool cannot loosen a nut.

Corrosion and worn-out bolt and nut have affected the joint-loosening torque.

Apply a higher torque, within the torque chart spec. If it does not help, use a larger tool, if available, to remove the nut. Do not apply a higher pressure than specified, as it will shorten the service life of the tool.

The tool has been flushed with a large amount of water.

The pressurized air system is affected by a large amount of condensed water.

See service recommendation for specific environments.
