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 lu-
bricator.

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.
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 EN LTV39-2 R56-HAD

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 vibra-
tion.
■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 deter-
mine the amount of reaction force that an operator can tolerate. Adapt the torque setting to the op-
erator'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
Instructions for reversing
Changing the rotation direction of the tool can only be done when the lever is completely released.
Clockwise rotation
Grip the gear shift ring and pull it backwards (A). Turn it counterclockwise until stop (B). Release the shift
ring and make sure that the shift ring returns to its most forward position.
Only the arrows indicating clockwise rotation should be visible (D).

LTV39-2 R56-HAD EN Operation
© Atlas Copco Industrial Technique AB - 9839 2906 01 9
Counterclockwise rotation
Grip the gear shift ring and pull it backwards (A). Turn it clockwise until stop (C). Release the shift ring and
make sure that the shift ring returns to its most forward position.
Only the arrows indicating counterclockwise rotation should be visible (E).
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
Recommended equipment for verification if tightening torque are an Atlas Copco Torque Analyser plus an
appropriately-sized transducer together with the available test joints.
Air Pressure Monitoring, RE-Signal S1
Reporting pneumatic assembly tools provide a pneumatic signal that indicates which part of the tightening
cycle the tool has reached, by means of variations in air pressure.
In the RE-Controller box timers are triggered when certain pressure levels are reached.
Pressure level 1 (P1) starts a timer that checks that the tightening cycle is not too short.
Pressure level 2 (P2) starts a timer that checks the time taken from when the clutch has been released to
when the operator releases the trigger to ensure that it is not too short.
The controller measures the differential pressure over the motor.
It should be noted that the system does not measure torque! Regular check of installed torque/torque out-
put of the tool must be done separately.
The RE-Controller checks the air-line pressure. One of the most common problems in air-line systems is
pressure variations. If the pressure drops too much the tool might stall and/or the torque will not be cor-
rect. The RE-Controller will give a signal if the pressure drops too much.

Operation EN LTV39-2 R56-HAD
10 © Atlas Copco Industrial Technique AB - 9839 2906 01
The RE-Controller alerts the operator when it detects:
■Missed fasteners
■Premature tool shut-off
■Stripped threads
■Cross-threading
■Rehits
■Drop in air supply
The air pressure inside the tool is measured through a small hose (see Optional accessories - Kit RE-Sig-
nal) and converted into a digital signal. This signal is processed in the RE-Controller. The RE-Controller
gives instant visual and audio feedback to the operator on whether the tightening was OK or not OK.
For further information, please see leaflet 9833 1358 01.

Service instructions
Overhaul and preventive maintenance is recommended at regular intervals once per year or after maxi-
mum 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 is not working properly, it should immediately
be taken away for inspection.
The strainer at the air inlet and the exhaust silencer should be cleaned frequently 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.

LTV39-2 R56-HAD EN Service
© Atlas Copco Industrial Technique AB - 9839 2906 01 13
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 replaced.
Tightening of Threaded Connections
The tightening torques indicated in the exploded views list in ServAid (see Spare parts section in https://
servaid.atlascopco.com) are established to achieve the correct clamping force and prevent the parts from
coming loose.
When servicing these parts, they must be able to open up without being destroyed. In special circum-
stances (depending on application and usage) the parts may however come loose after some time of op-
eration. In such cases the torque can be increased by 10-20%. If necessary, a low or medium threadlock-
ing fluid can also be applied.
Example
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 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.

Lubrication of Gears in Clutch Casing
Lubricate according to the Lubrication Guide.
Lubrication of motor parts
■No grease is needed for protected Ball bearings.
■Apply a thin layer of oil where needed.
Lubrication
■Lubricate the gears, the valve and the clutch according to the Lubrication Guide at each service occa-
sion.
■Lubricate o-rings and threaded connections with grease before assembling.
■Lubricate the trigger, the needle bearings and the ball bearings with grease during the regular over-
haul of the tool.
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.

Dismantling/Assembling Instructions
Dismantling of Motor
Tightening of Threaded Connections
The tightening torque indicated in the exploded views (see Spare parts section in https://
servaid.atlascopco.com) will give the right clamping force and prevent parts from loosening. It is important
not to exceed the clamping force, these parts must be able to open up without being damaged at service.
After some time of operation and in special circumstances, depending on application and usage, the parts
may however loosen somewhat. The tightening torque can then be increased by 10-20% and some type
of low or medium thread locking fluid can be applied.
