Safety and operating instructions

compressed air contains a small quantity of oil

e.g. supplied from a fog lubricator (DIM) or Dosol

system.

This does not apply to turbine tools, which should

be kept oil free.

Compressed air connection

• The machine is designed for a working pressure

(e) of 6–7 bar = 600–700 kPa = 87–102 psi.

• Blow out the hose before connecting.

Handling

Tightening torque

For accurate operation and safety, the tightening

torque of the nut runner must be set correctly in rela-

tion to the screw joint. Check the tightening torque

given to the joint in question.

The air pressure is set at a suitable level – depend-

ing upon the required tightening torque – with the

aid of a compressed air regulator. Installation of an

Atlas Copco regulator is recommended.

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

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').

Service instructions

Overhaul and preventive maintenance is recommen-

ded at regular intervals once per year or after maxim-

um 100.000 tightenings 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 immedi-

ately 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 accur-

ately and defective or worn parts (i.e. O-rings, vanes)

should be replaced.

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.

Lubrication

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.

When making the regular general overhaul of the

machine, the throttle valve, ratchet attachment, ball

bearings and needle bearings should be lubricated

with grease.

Use good quality lubricants. The oils and greases

supplied by the oil companies mentioned below are

examples of lubricants which we can recommend.
