LTV29-2 R30-10 EN Safety and operating instructions
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 equipment.

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 lubricated with grease during
the regular overhaul of the machine.
The angle gear and clutch must be lubricated using grease that contains molybdenum 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 monitoring instrument that
counts the number of approved tightening and detects premature shut-off and rehits and other irregulari-
ties.
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 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 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.
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.
