Service overview
Overhaul and preventive maintenance
An overhaul should be done once per year or after a maximum of 100.000 tightening. More frequent pre-
ventive maintenance and overhaul are needed if the tool is used in heavy-duty operations. If the tool is not
working correctly take it out of service immediately for inspection.
At overhaul and maintenance:
■clean all parts thoroughly
■replace worn or defective parts
■lubricate the threads and o-rings with grease before assembly
■make sure that the threaded connections on the tool are tightened in accordance with the specifica-
tions on the exploded views

The table below shows the recommended service interval.
The service must only be done by an authorized workshop or qualified service technician.

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

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 mo-
tor.
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 lu-
bricator.

Compressed air connection
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 acces-
sories, or when making repairs.
WARNING Whipping hoses can cause serious injury
►Always make sure that there are no damaged or loose hoses or fittings.
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 section Technical data.
Make sure that the hose and couplings are clean and free from dust before connecting to the tool.
Installation instructions
Installation of vibrating tools
We recommend using a minimum length of 300 mm (12") of flexible hose for compressed air between a vi-
brating tool and the quick-action coupling.

Operation
Ergonomic guidelines
Consider your workstation as you read through this list of general ergonomic guidelines and see if you can
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 convenient reach range by determining where parts or tools should 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 reducing 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.
■Make sure to take frequent breaks.
■Avoid extreme arm or wrist postures, particularly for operations requiring a degree of force.
■Adjust for convenient field of vision by minimizing movement of the eyes and head during the work
task.
■Use the appropriate lighting for the work task.
■Select the appropriate tool for the work task.
■Use ear protection equipment in noisy environments.
■Use high-quality inserted tools or 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 wheel is either bent or if it is not guided properly. Make sure to
use the correct flanges for cut-off wheels and avoid bending the wheel during cut-off operation.
■When drilling:
The drill might stall when the drill bit breaks through. Makes sure you use support handles if the
stall torque is too high. The safety standard ISO11148 part 3 recommends using something to ab-
sorb the reaction torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.
■When using direct-driven screw or nutrunners:
Reaction forces depend on tool setting and joint characteristics. The ability to bear reaction forces
depends on the operator’s strength and posture. 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.
■Use dust extraction system or mouth protection mask in dusty environments.
Operating instructions
Tightening time
Use a tightening time of 1-5 seconds. Longer tightening or loosening times will increase wear, cause mal-
function and risk of breakage.
Long sockets and extensions
Use extensions and standard sockets instead of long or extra long sockets as the lower inertia/mass of the
extension will give less stress on the impact mechanism.
However an extension will reduce the applied torque to some degree.

W2915 EN Operation
© Atlas Copco Industrial Technique AB - 9839 0740 01 9
Tightening torque
The tightening torque force depend on:
■the air pressure
■the tightening time
■the bolted joint
The tightening torque force is reduced by extension pieces and worn sockets. Oversized power sockets
(diameter or length) will overload the impact mechanism and reduce the life of vital parts.
Use the impact wrench within the specified torque range.
Never override the recommended maximum tightening torque.

ventive maintenance and overhaul are needed if the tool is used in heavy-duty operations. If the tool is not
working correctly take it out of service immediately for inspection.

■replace worn or defective parts
■lubricate the threads and o-rings with grease before assembly
■make sure that the threaded connections on the tool are tightened in accordance with the specifica-
tions on the exploded views

All parts Clean all parts before inspection.
Bearings Make sure that the bearings are free from damages and runs smoothly.
End plates ■Make sure that the end plates surfaces are not scratched or damaged.
■Do a flatness test of the end plates surfaces. If they are visibly worn or deformed, polish
with fine grinding paste against a surface plate and then clean thoroughly.
Rotor Make sure:
■that the end faces have no marks or burrs
■that the splines are not worn or cracked
■that the plug holes have no cracks.
Cylinder ■Make sure that the bore is not scratched or damaged.
■If the end surfaces are rough, polish with fine grinding paste against a surface plate and
then clean thoroughly.
Inspection of strainer
Clean the strainer at the air inlet frequently to prevent clogging which decreases the capacity of the tool.
Replace a defective or worn strainer.
Inspection of silencer
Change or clean the filters regularly. Clogged filters will reduce power output.
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 fil-
ter 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.
Lubricating guide
Use lubricants of good quality. The oils and greases listed in the lubrication table are examples of lubri-
cants that can be recommended.
