Safety and operating instructions
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
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.
• Note – This does not apply to turbine tools, which
should be kept oil free.
Compressed air connection
• The machine is designed for a working pressure
of 6–7 bar = 600–700 kPa = 87–102 psi.
• Blow out the hose before connecting.
Installation proposal
Choosing the correct couplings, hose and clamps can
be a troublesome digging into details. To save your
time and to ensure correct capacity of the airline in-
stallation, from the tapping point to the tool, we offer
you an installation proposal.
Filtered, regulated and injection lubricated air for a
max. air flow of 8 l/s

Handling
Setting of tightening torque
A
The adjusting screw is accessible through
the hole in the housing. If necessary, turn the
outgoing spindle.
After adjusting, it is important to remember to as-
semble the plug of the hole in the housing.
It is recommended to start at min. torque setting
- when the adjustment screw is screwed out approx.
6 turns from the bottom position. Do not screw out
any further.
When using the machine above recommended
maximum torque it might result in improper function
and faster wear. Always check the setting on your
actual joint.
Test method - Static or Dynamic
A static torque measurement is recommended for
the ErgoPulse machines.
If dynamic torque measurement with an electronic
inline torque transducer is used, always verify your
measurement result by a static check with a torque
wrench (electronic).

Guide to Pulse Tools". Ordering No. 9833 1225 01.
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. Alternatively
consider an automatic lubricator device, Atlas Copco
oil fog lubricator DIM, or single point lubricator
DOS, which will improve the machine performance.
Refill the pulse-unit with oil
For further information pls see - Service Instructions.
For optimum machine performance the pulse unit
must be correctly filled with oil. Due to a possible
microleakage of oil from the pulse unit, it could be
necessary to refill the unit between the regular over-
haul intervals. The frequency of this procedure de-
pends on the type of application, number of cycles,
tightening time etc. An accurate refill of the pulse
unit gives long service intervals.
Too much oil in the pulse unit implies a low pulse
frequency and slow tightening.
