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.
Handling
Tightening torque
The torque obtained depends on air pressure and
tightening time on the actual joint. Extensions and
worn sockets will reduce the delivered torque. The
impact wrench should be used within the specified
torque range. Never use the machine over recommen-
ded maximum torque. Might result in improper
function and faster wear.
Test methods
A static torque measurement is recommended for
impact wrenches.
For test on hydraulic tension tester and for test on
joints.
Maintenance
Service instructions
Overhaul and preventive maintenance is recommen-
ded at regular intervals once per year or after maxim-
um 100.000 tightenings depending on which occurs
sooner. More frequent overhaul may be needed if
the machine is used in heavy-duty operations. If the
machine not is working properly, it should immedi-
ately be taken away for inspection.
The strainer at the air inlet and the exhaust silencer
should be cleaned frequently or replaced in order to
prevent clogging, which decreases the capacity.
At the overhauls, all parts should be cleaned accur-
ately and defective or worn parts (i.e. O-rings, vanes)
should be replaced.
It is important that the machines threaded connec-
tions are tightened properly; i.e. in accordance with
the specifications on the exploded views. Before as-
sembly, lubricate the threads with grease.
A
All o-rings should be greased before assem-
bling.

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 (see
'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.
