Safety and operating instructions
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.

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.
Too little oil in the pulse unit implies a high pulse
frequency and there will be a risk of a decreasing
tightening torque. In particular at the first tightening
after a break the machine might race.
Use Hydraulic Oil : 22 cST / 40 °C (ISO VG22).
Running the machine with too little oil may dam-
age the pulse unit.
After the refill – Check the tightening torque, see
Service instructions.
Rust protection and internal cleaning
Water in the compressed air, dust and wear particles
cause rust and sticking of vanes, valves etc. An air
filter should be installed close to the machine (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 recommen-
ded at regular intervals once per year or after maxim-
um 250.000 tightening depending on which occurs
sooner. More frequent overhaul may be needed,
specially replacing of oil in the pulse unit, if used at
