The torque range of each spring is easily identified
by it's colour.
Maintenance
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. Alterna-
tively consider an automatic lubricator device, At-
las Copco oil fog lubricator DIM, or single point
lubricator DOS, which will improve the machine
performance.
Rust protection and internal cleaning
Water in the compressed air, dust and wear parti-
cles cause rust and sticking of vanes, valves etc.
An air filter should be installed close to the ma-
chine (se 'Air quality'). Before longer standstills,
flush with oil (some drops) into the air inlet, run
the machine for 5-10 seconds when absorbing the
oil in a cloth.
Service instructions
Overhaul and preventive maintenance is recom-
mended 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 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 accu-
rately and defective or worn parts (i.e. O-rings,
vanes) should be replaced.
Disassembling /assembling
It is important that the machines threaded connec-
tions are tightened properly; i.e. in accordance
with the specifications on the exploded views.

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 over-
hauls.
Inspection
After the cleaning, inspect all parts. Damaged and
worn parts should be replaced.
Lubrication
Lubricate specially gears, valve and clutch with
grease containing molybdenum disulphide (e.g.
Molykote BR2 Plus). Lubricate o-rings and
threaded connections with grease before assem-
bling.
Spare parts
Parts without ordering number are for technical
reasons not delivered separately. The use of other
genuine Atlas Copco replacement parts may result
in decreased tool performance and increased main-
tenance and may, at the company option, invali-
date all warranties.
