Safety and operating instructions
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 mm3)
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 13 mm (1/2") .
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.
Overhaul should be carried out more frequently under
more rigorous operating conditions.
A
Clean the engine thoroughly.
Fit the engine and check that it rotates freely.
Pour two drops of oil into the air intake and
idle the engine for 5-10 seconds.
A
If the compressed air is very dry, the idle
speed for lubricant-free engines may de-
crease slightly after fairly long periods of
operation. This decrease may amount to 10-
15%.
Shaft load
The maximum shaft loads stated in our sales literat-
ure and on the last page must not be exceeded in or-
der to prevent an excessive increase of the bearing
temperature. In the diagram on the last page you will
find the accepted shaft load.
