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.

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.

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.
