The non-reversible air motor
may be operated
by a simple shut-off valve. One hose or pipe connects
the motor and valve.
The reversible air motor
may be operated by a
5-port valve. Two hoses or pipes connect valve with
the motor inlet ports.
If the motor is to be used in explosive environ-
ment filter/silencers must be installed at the motor
outlet ports.
A
A damping of the motor sound is obtained
by connecting a silencer to the motor exhaust
port. Further silencing is obtained by leading
away the exhaust by a hose to a separate
exhaust chamber.
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 recom-
mend the installation of an Atlas Copco refrigera-
tion-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 li-
quid water. The filter must be installed as close
as possible to the machine/equipment 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-fog 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).
(May be found in our sales literature).
D
= Number of drops per min (1 drop = 15 mm
3
)
L* 0.2 = D
this applies to the use of long work cycle air line
tools. A single point lubricator 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
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.
• Recommended hose size is 16 mm (5/8") .
Maintenance
Overhaul
The air motor must be taken out of service for inspec-
tion as soon as any sign of fault occurs. The service
intervals vary depending on the speed of the motor
and the quality of the air.
Lubrication
Planetary gears, ball- and needle bearings and seal
ring should be lubricated with grease in conjunction
with the regular overhaul of the motor. Molykote
BR2 Plus gives long intervals between lubrications.
Always use lubricants of good quality. The oils
and greases mentioned in the chart 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.
This can be prevented by flushing with oil (some
drops), running the motor for 5-10 seconds and ab-
sorbing the oil in a cloth. Protect the tool this way
before longer standstills.
Overhaul
To achieve the best engine service life under normal
operating conditions, regular overhaul and cleaning
should be carried out every 12 months or after every
2000 hours of operation, whichever is the sooner.
