Safety and operating instructions
Safety instructions
Warning
Make sure you are familiar with the operating instructions before you use the
machine.
Before making any adjustments (e.g. setting the torque, changing bits) discon-
nect the machine from the compressed air line.
The machine, together with any attachments and accessories, must never be
used for anything other than the designed purpose.
Use power sockets only. For safe and economic use - replace worn sockets.
Check that the power socket is properly fastened - replace the square drive re-
tainer when necessary.
Keep your fingers and loose articles (cloths, hair) away from the outgoing shaft.
Do not use gloves.
Hold the machine correctly and be aware of the reaction force.
Never use the nutrunner without making sure that the clutch releases. Be aware
of fluctuations in air pressure.
Check the direction of the rotation before using the machine.
When working in close spaces without the use of a torque reaction bar - there is
a risk of injuries due to squeezing.
The operators of a nutrunner with a torque reaction bar should take particular
care to avoid injuries due to squeezing. Never put your hand on or close to
the torque reaction bar while the machine is being used.
When using a suspension yoke, check that it is in good condition and correctly
fastened.
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.
General information
ATEX certification information
• ATEX Certificate Number:
DEKRA BVS 08 ATEX H 063 X
• The marking code is:
EX II 2 GD IIB 135°C (T4)
Please make sure that the offset screwdriver is only used for intended purposes.
In the event of an inappropriate use, impacts sparks can occur between the
socket wrench and the screw or nut that is to be tightened. It is therefore recom-
mended to use torque wrenches exclusively. Before using the offset screw-
driver, please make sure that this tool is not worn and that a perfectly tight-fit-
ting connection is assured between the offset screwdriver and the screw or nut
that is to be tightened. Furthermore, it must also be assured that there is a per-
fectly tight-fitting connection between the square drive pin of the screwdriver
Safety and operating instructions EN LTV39-2 R48-10-ATEX

and the square retainer of the torque wrench. Furthermore, the offset screw-
driver must be earthed to the equipotential bonding system of the workshop, for
instance through suitable accessories such as hoses and air-pressure connec-
tions.
National safety regulations must be properly observed, if the tool is to be used
in areas that are subject to an explosion hazard. It is the responsibility of the
user to make sure that all possible accessories for the tool, such as wrenches
and air connections, conform to the national safety regulations for equipment
used in potentially explosive areas.
Maintenance and repairs of the tool must be carried out exclusively by au-
thorised personnel, after which a no-load test of at least 10 minutes and
temperature measurements must be carried out and recorded in a protocol.
A maximum surface temperature of 135°C may not be exceeded.

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.

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 tightening torque is adjusted by altering the tension of the clutch spring.
Turn the protection ring until the hole in the clutch housing is free. Then turn
the out going spindle until you can see the keyhole in the adjustment washer.
Turn the adjustment key clockwise to decrease and anticlockwise to increase
the torque. After the adjustment, turn the protective ring back again.
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.
Operating instructions
See figure in Service instructions
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:
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.
