Replacement of Vanes

Replace the vanes in the motor when a power drop of the tool is experienced. If the vanes are not replaced in time other motor parts may be damaged. For increased life length of the vanes use an oil lubricator to dose oil into the air inlet.

General Service and Maintenance Safety

Do not dismantle the tool.

The service must only be done by authorized workshops or qualified service technicians.

WARNING

Polymer hazard

The vanes in this product contain PTFE (a synthetic fluoropolymer). Due to wear, there might be PTFE particles inside the product. Heated PTFE can produce fumes which may cause polymer fume fever with flu-like symptoms, especially when smoking contaminated tobacco.

Health and Safety recommendations for PTFE must be followed when handling vanes and other components:

• Do not smoke when servicing this product

• PTFE-particles must not come in contact with open fire, glow or heat

• Motor components must be washed with cleaning fluid and not blown clear with an air line

• Wash your hands before starting any other activity

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

Overhaul and Maintenance

WARNING

Risk of Serious Injury or Death

Overspeed can result in serious injury or death.

• If a speed governor is used, make sure that the correct speed governor is assembled. Careless handling may put it out of order

• Do not disassemble security parts and always replace them if they are damaged.

• Always do a free speed check of the tool after service.

Perform an overhaul of the tool at six-months intervals. Inspect and maintain the tool more often if it is in heavy duty service or not running correctly.

Clean the motor parts and apply a thin layer of air lubrication oil onto the vanes and inner surface of cylinder and end plates.
Assemble the motor and make sure that it is running free. Add two drops of oil through the air inlet and run the motor at idling speed for 5-10 seconds.

Change the grease in the angle gear after approximately 200 hours of operation. See Lubrication.

Inspect the sealing lip and adjacent column for wear. The seal is essential to keep lubricant in the gear box.

Installation Requirements

• Air Quality
• Air Lubrication Guide
• Compressed Air Connection

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.

Air Lubrication Guide

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.

Operation

• Ergonomic Guidelines
• Operating Instructions
  • Setting-up Instructions
  • Mounting of Wheel and Carbide Burr

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.

• Do not manipulate the speed of the tool.

• Do not override the maximum speed marked on the tool.

Testing of the tool should only be done by professional technicians. The technicians must be authorized to test this type of tool and to operate a pneumatic system in accordance with national directives.

• Do a free speed check of the tool every day and whenever the tool has been serviced. Do the free speed check with the grinding equipment removed.
  

• Use a pressure regulator to prevent a too high air pressure which can cause overspeed.

• Make sure that connections and the air hose are in good condition.

Mounting of Wheel and Carbide Burr

WARNING

Compressed air can cause serious injury

• Always shut off the air supply, drain hose of air pressure and disconnect the tool from air supply; when not in use, before making any adjustments to the product - for example changing accessories, or when making repairs.

WARNING

Risk of Serious Injury or Death

Wrong insert tool can burst and cause serious injury or death.

• Use an insert tool with a max operating speed higher than or equal to the tool speed.

• Do not use any other insert tool than specified by the manufacturer (no cutting off wheels or router bits).

• Use only recommended sizes and types of abrasives.

• Do not use mounting wheels that are chipped or cracked, or may have been dropped.

• Correct mounting is necessary to prevent injury from broken mounted wheels

• Make sure that the shaft diameter of the accessory is correct for the size of the collet.

• Do not mix mm shanks with inch collets and vice versa.

• Observe a minimum of 10 mm axial grip of the shank.

• When fitting mounted wheels or burrs, reduce the overhang by pushing the shank all the way into the collet. (Check also the recommendations given by the tool manufacturer)

• Observe that increased overhang of shank reduces the permissible speed.

• Before starting the machine, check that the collet is tightened correctly.

• Do a test run of every new mounted wheel in a safe position for 30 seconds. Use a barrier such as under a heavy work table to stop any possible broken wheel parts. Stop immediately if the vibration is excessive.

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 standstills 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.

Lubrication Guide

Use lubricants of good quality. The oils and greases listed in the lubrication table are examples of lubricants that can be recommended.

Lubrication Angle Gears

Lubrication

The tool is fitted with an angle gear which is lubricated with a fluid grease to ensure good wear resistance. To avoid overfilling, which could result in a rise in temperature and damage to seals, there is no lubrication nipple. Change the grease after approximately 200 running hours by removing the angle-gear spindle.

For accurate lubrication propertiets use Rhenus LKR03 fluid grease. The requisite amount of grease is max. 6 cm³.

Do not use ball bearing grease or chassis grease.
