Installation
Installation of vibrating tools
It is recommended that a minimum length of 300 mm of flexible hose for com-
pressed air is inserted between a vibrating tool and the quick-action coupling.
Air quality
• For optimum performance and maximum machine life we recommend the
use of compressed air with a maximum dew point of +10°C. We also rec-
ommend the installation of an Atlas Copco refrigeration-type air dryer.
• Use a separate air filter of type Atlas Copco FIL. This filter removes solid
particles larger than 15 microns and also removes more than 90 % of liquid
water. The filter must be installed as close as possible to the machine/equip-
ment and prior to any other air preparation unit such as REG or DIM (please
see Air Line Accessories in our main catalogue). Blow out the hose before
connecting.
Models which need air lubrication:
• The compressed air must contain a small quantity of oil.
We strongly recommend that you install an Atlas Copco oil lubricator
(DIM). This should be set according to air consumption by the air line tool
according to the following formula:
L = Air consumption (litre/s)
D = Number of drops per min (1 drop = 15 mm3)
L* 0.2 = D
this applies to the use of long work cycle air line tools. A single point lubri-
cator type Atlas Copco Dosol can also be used for tools with short running
cycles.
Information about Dosol settings may be found under Air Line Accessories
in our main catalogue.
Lubrication-free models:
• In the case of lubrication-free tools it is up to the customer to decide on the
peripheral equipment to be used. However, it is no disadvantage if the com-
pressed air contains a small quantity of oil e.g. supplied from a fog lubrica-
tor (DIM) or Dosol system.
•Note – This does not apply to turbine tools, which should be kept oil free.
Compressed air connection
• The machine is designed for a working pressure of 6–7 bar = 600–700 kPa =
87–102 psi.
• Blow out the hose before connecting.

Installation proposal
Choosing the correct couplings, hose and clamps can be a troublesome digging
into details. To save your time and to ensure correct capacity of the airline in-
stallation, from the tapping point to the tool, we offer you an installation pro-
posal.
For more information please read, Atlas Copco Industrial Power Tools cata-
logue Ordering No. 9837 3000 01.
Handling
Tightening torque
For accurate operation and safety, the tightening torque of the nut runner must
be set correctly in relation to the screw joint. Check the tightening torque given
to the joint in question.
The air pressure is set at as high a level as possible up to max 6.3 bar – with the
aid of a compressed air regulator. Installation of an Atlas Copco regulator, type
MIDI REG 15, is recommended.
Loosen the set screw and adjust the torque setting by means of the screw. The
torque is increased when screwing the screw clock-wise. After adjustment,
tighten the screw.
If shut-off is carried out at high speed of revolution, causing a high torque
scatter, it is recommended to reduce the air pressure.
Verification of tightening torque
Atlas Copco Torque Analyser, ACTA 3000, plus an appropriately-sized in-line
transducer, IRTT together with the available test joints are recommended equip-
ment.
Reaction bar
Adapt and use the torque reaction bar (see figure in Service instructions) as fol-
lows:

Safety and operating instructions EN LTP51 H

1 Shaping the reaction bar, Fig. A
The torque reaction bar must be shaped to fit a suitable fixed support. To avoid
overloading of the bearings for the tool drive and of the reaction bar, the
point of contact on the reaction bar should be within the shaded area (F),
see Fig. A.
• Measure the distance (L) for the hexagon sleeve to be used. Mark out points
(A and B) on a sheet of paper.
• Consult Table No.1 to find the angle (α) applicable to the diameter (D) of
the machine and the tightening torque in question. Draw a line from point
(A) in angle (α) from the centre line (A – C).
• Draw a line (B – E) at right angles (90o to the centre line (A – C) of the ma-
chine from point (B). Starting at point (B), draw two lines at angles of +15o
and -15o respectively from the marked 90o-line.
• Mark the area (F) between the drawn lines.
• Adapt the shape of the reaction bar so that the point of contact (K) falls
within the marked area (F). The minimum breaking force is obtained if
the point of contact (K) is on or close to line (B – E).
• If the point of contact falls within angle (α) – in area (G) – there is a risk of
overloading of the bearings for the machine drive and deformation of the re-
action bar.
• If the point of contact is outside angles ± 15o – in areas (H) – there is a risk
of rapid wear of the hexagon sleeve and reduced torque accuracy.
2 Bending, Fig. B
• Heat the spot to red colour.
It is recommended to concentrate the heat to the inside radius in order not
to reduce the original width (W), see fig. B.
• After bending, allow to cool slightly in room temperature and then chill.
• In order for the torque reaction bar to be as light as possible it is recom-
mended that the section outside the bend be configured as shown in Fig. B.
After bending, attach the accompanying warning sign to the reaction bar,
see fig. C, and mark the side of the reaction bar that should be placed
against the support i a suitable way.
3 Assembly
• Place the reaction bar in the wanted position on the machine.
• Tighten the nut to a torque of 70 Nm, 90 Nm or 100 Nm respectively.
• Check regularly that the lock ring is firmly secured.
4 Use
• Apply the reaction bar according to figure C – opposite the direction of the
drive of the machine – before starting the machine.
•Never put your hand on or close to the reaction bar while the machine is
being used.

Maintenance
For maximum performance
It is important to lubricate regularly to get maximum performance and trouble-
free operation. The motor should be lubricated with oil; i.e. drops of oil can be
dropped either into the compressed air or directly into the air inlet.
The trigger, planetary gears, needle bearings and ball bearings should be lubri-
cated with grease during the regular overhaul of the machine.
The angle gear and clutch must be lubricated using grease that contains molyb-
denum disulphide: Molykote BR2 Plus, for example, or an equivalent brand.
Use lubricants of good quality. The oils and greases mentioned in the table are
examples of lubricants which are recommended.
Rust protection and internal cleaning
Water in the compressed air, dust and wear particles cause rust and sticking of
vanes, valves etc. An air filter should be installed close to the machine (see ‘Air
quality’).

Reporting, RE – signal
Reporting (RE) machines supply an air signal that can be connected to a moni-
toring instrument that counts the number of approved tightening and detects
premature shut-off and rehits and other irregularities.
Service instructions
Overhaul and preventive maintenance is recommended at regular intervals once
per year or after maximum 250.000 tightening depending on which occurs
sooner. More frequent overhaul may be needed, if used at high torque and long
tightening times. If the machine not is working properly, it should immediately
be taken away for inspection.
The strainer at the air inlet and the exhaust silencer should be cleaned fre-
quently or replaced in order to prevent clogging, which decreases the capacity.
At the overhauls, all parts should be cleaned accurately and defective or worn
parts (i.e. O-rings, vanes) should be replaced.
Disassembling / assembling
It is important that the machines threaded connections are tightened properly;
i.e. in accordance with the specifications on the exploded views.
Lubricate o-rings and threaded connections with grease before assembling.
Cleaning
Clean all parts thoroughly in white spirit or similar cleaning agent. To prevent
clogging and decreased power, it could be necessary to clean the strainer (if
used) and the exhaust filter between the overhauls.
Inspection
After the cleaning, inspect all parts. Damaged and worn parts should be re-
placed.
Lubrication
Lubricate specially gears, valve and clutch with grease containing molybdenum
disulphide (e.g. Molykote BR2 Plus). Please see exploded views and fig. under
Service instructions.

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, compo-
nent 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 as-
sembly operations.
• When working above shoulder level, reduce the load on the static mus-
cles 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 requir-
ing 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 ex-
cessive levels of vibration.
• Minimize exposure to reaction forces.
• When cutting:

Safety and operating instructions EN LTP51 H
10 © Atlas Copco Industrial Technique AB - 9836 938172 72
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 absorb 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 abil-
ity to bear reaction forces depends on the operator’s strength and pos-
ture. 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.

Noise and Vibration Declaration Statement
These declared values were obtained by laboratory type testing in accordance
with the stated standards and are suitable for comparison with the declared val-
ues of other tools tested in accordance with the same standards. These declared
values are not adequate for use in risk assessments and values measured in indi-
vidual work places may be higher. The actual exposure values and risk of harm
experienced by an individual user are unique and depend upon the way the user
works, the workpiece and the workstation design, as well upon the exposure
time and the physical condition of the user.
We, Atlas Copco Industrial Technique AB, cannot be held liable for the con-
sequences of using the declared values, instead of values reflecting the actual
exposure, in an individual risk assessment in a work place situation over which
we have no control.
This tool may cause hand-arm vibration syndrome if its use is not adequately
managed. An EU guide to managing hand-arm vibration can be found by ac-
cessing http://www.pneurop.eu/index.php and selecting 'Tools' then 'Legisla-
tion'.
We recommend a programme of health surveillance to detect early symptoms
which may relate to noise or vibration exposure, so that management proce-
dures can be modified to help prevent future impairment.

Tightening of threaded connections
The tightening torques indicated in the spare parts list are established to achieve
the correct clamping force and to prevent the parts from coming loose. When
serviced these parts must be able to open up without being destroyed. In special
circumstances (depending on application and usage) the parts may however
come loose after some time of operation. In such cases the torque could be in-
creased 10-20% and if necessary some type of low or medium threadlocking
fluid could also be applied.
Example
Assembly
Remove silencer and air nipple. Then completely remove the old Rubber cover.
Fix the Motor casing in a vice. To easy the assembly put some soap-water mix-
ture on the new Rubber cover ends. Make a loop of a heawy duty strap and then
put the loop of strap through the Rubber cover and then around the Handle, see
illustration 1 below. Pull on strap until Rubber cover is completely over the
lower part of handle.
Gluing
When cover is in correct position clean the ends of cover from soap. Then care-
fully apply glue (Loctite 406) on the inside around edges and in the middle of
cover, see illustration 2 below. It is especially important that the surface near
the trigger is carefully coated with glue. Press Rubber cover so it fits nice and
thight, see illustration 3 below.

utilisation, l’opérateur devra connaître le fonctionnement de l’outil dans toutes
les conditions de travail possibles et se sera entraîné à son maniement. Il devra
également veiller à ce que l’outil ne soit manipulé par aucune personne qui n’a
pas reçu la formation requise. Reportez-vous à la section intitulée “Toc de réac-
tion”.
L’outil doit être utilisé exclusivement avec le toc de réaction correspon-
dant, qui doit être adapté à l’assemblage à effectuer. Reportez-vous également
aux instructions de la section “Toc de réaction”.
Ne posez jamais la main sur le toc de réaction ou à proximité de celui-ci pen-
dant l’utilisation de l’outil.
Vérifiez si la douille impact est correctement fixée. Remplacez la goupille de
rétention ou de verrouillage s’il y a lieu. Remplacez également les douilles
usées.
Maintenez les mains, les cheveux longs ou tout autre objet à l’écart de la broche
rotative.
Ne pas utiliser de gants.
Lorsqu'un anneau de suspension est utilisé, vérifiez son état et assurez-vous
qu’il est correctement fixé.

Installation
Installation d'outils vibrants
Il est recommandé d'insérer une longueur minimale de 300mm de tuyau souple
pour air comprimé entre un outil vibrant et le raccord rapide.
Qualité de l'air
• Pour assurer à la machine des performances optimums et une durée de vie
maximum, nous recommandons d'utiliser de l'air comprimé avec un point de
rosée maximum de +10°C. Nous recommandons également d'installer un
déshydrateur d'air Atlas Copco à réfrigération.
• Utilisez un filtre à air indépendant de type Atlas Copco FIL. Ce filtre retient
les particules solides supérieures à 15 microns et plus de 90 % d'eau sous
forme liquide. Il doit être placé aussi prêt que possible de la machine ou de
l'équipement et avant toute autre unité de préparation de l'air telles que des
unités REG ou DIM (voir "Accessoires de distribution d'air" dans notre ca-
talogue général). Mettez le flexible à l'air libre avant de le raccorder.
Modèles nécessitant une lubrification de l'air :
• L'air comprimé doit contenir une petite quantité d'huile.
Nous recommandons fortement l'installation d'un graisseur à brouillard
d'huile Atlas Copco (DIM). Celui-ci devra être réglé en fonction de la
consommation d'air de l'outil pneumatique conformément à la formule sui-
vante :
L = Consommation d’air (litre/s).
(voir notre documentation commerciale).
D = Nombre de gouttes par minute (1 goutte = 15 mm3)
L* 0.2 = D
cette formule s'appliquant aux outils pneumatiques à cycle de fonctionne-
ment long. Avec des outils à cycle de fonctionnement court, vous pouvez
également utiliser un lubrificateur à un seul point type Atlas Copco Dosol.
Vous trouverez des informations sur le réglage du Dosol dans notre cata-
logue général, sous le chapitre "Accessoires de distribution d'air".
Modèles sans lubrification :
• Pour les outils n'exigeant pas de lubrification, le client a le choix de l'équi-
pement périphérique à utiliser. Néanmoins, il n'y a aucun inconvénient à ce
que l'air comprimé contienne une petite quantité d'huile fournie par un équi-
pement tel qu'un graisseur à brouillard d'huile (DIM) ou un système Dosol.
•Remarque – ceci ne concerne pas les outils à turbine qui doivent rester
exempts d'huile.

Raccordement de l'air comprimé
• L'outil est conçu pour une pression d'utilisation de 6 à 7 bar = 600 – 700 kPa
= 6 – 7 kg/cm2.
• Soufflez de l’air dans le flexible avant de le connecter.
Solution d'installation proposée
Choisir le raccord adapté, le tuyau et les colliers peut devenir un sérieux soucis
dans le détail. Pour économiser votre temps et garantir une capacité de débit de
votre installation d’air comprimé, de la ligne principale jusqu’à l’outil, nous
vous proposons une installation adaptée à chaque outil.

trial Power Tools réf. 9837 3000 01.
Administration
Couple de serrage
Pour garantir la sécurité et le bon fonctionnement de la visseuse, ajustez correc-
tement le couple de serrage en fonction du joint de la vis. Vérifiez les spécifica-
tions de couple du joint concerné.
La pression d'air est réglée aussi haut que possible, jusqu'à 6,3 bar au maxi-
mum, à l'aide d'un régulateur pour air comprimé. Le montage d'un régulateur
Atlas Copco, type MIDI REG 15, est recommandé.
Desserrez la vis d'arrêt et réglez le couple de serrage à l'aide de la vis. Tournez
la vis dans le sens des aiguilles d'une montre pour augmenter le couple. Une
fois le réglage terminé, serrez la vis d'arrêt.
Si l'arrêt s'opère à grande vitesse de rotation, provoquant une forte disper-
sion du couple, il est recommandé de réduire la pression d'air.
Vérification du couple de serrage
Nous vous recommandons d’utiliser l’Analyseur de couple Atlas Copco, ACTA
3000, ainsi qu’un transducteur en ligne de taille appropriée (IRTT) avec les
joints de test disponibles.
