Statement of use
This product is designed for installing and removing threaded
fasteners in wood, metal and plastic. No other use permitted. For
professional use only. The use of spare parts/accessories other than
those originally supplied by the manufacturer may result in a drop
in performance and/or increased maintenance/noise
level/vibrations, and as the result, the full cancellation of the
manufacturer's liability.
Installation
Air quality
– For optimum performance and maximum machine life we re-
commend use of compressed air with a dew point between
+2°C and +10°C. Installation of a refrigeration-type air dryer
is recommended.
– Use a separate air filter to remove solid particles larger than
30 microns and more than 90 % of water, installed as close as
possible to the machine and prior to any other air preparation
unit. Blow out the hose before connecting.
– The compressed air must contain a small quantity of oil. We
strongly recommend that you install a oil-fog lubricator to be
set normally at 3-4 drops(50mm
cycle running tools, or a single-point lubricator for short cycle
running tools.
– Regarding lubrication free tools it is, at the customers option,
no disadvantage if the compressed air contains a small quantity
of oil as supplied from a lubricator. An exception is turbine
tools that should be kept oil free. (For further information please
see Air Line Accessories in our main catalogue.)
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.
Handling
Tightening torque
For accurate operation and safety, the tightening torque of the nut
runner must be set correctly in relation to the screw joint. Check
the tightening torque given to the joint in question.
The tightening torque is adjusted by altering the tension of the
clutch spring. Turn the protection ring until the hole in the clutch
housing is free. Then turn the out going spindle until you can see
the keyhole in the adjustment washer. Turn the adjustment key
clockwise to decrease and anticlockwise to increase the torque.
After the adjustment, turn the protective ring back again.

For maximum performance
It is important to lubricate regularly to get maximum performance
and trouble-free operation. The motor should be lubricated with
oil; i.e. drops of oil can be dropped either into the compressed air
or directly into the air inlet.
The trigger, planetary gears, needle bearings and ball bearings
should be lubricated with grease during the regular overhaul of
the machine.
The angle gear and clutch must be lubricated using grease that
contains molybdenum disulphide: Molykote BR2 Plus, for ex-
ample, or an equivalent brand.
Use lubricants of good quality. The oils and greases mentioned
in the table 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. An air filter should be installed
close to the machine (see "Air quality").
Reporting, RE – signal
Reporting (RE) machines supply an air signal that can be connected
to a monitoring instrument that counts the number of approved
tightening and detects premature shut-off and rehits and other ir-
regularities.
Service instructions
Overhaul and preventive maintenance is recommended at regular
intervals once per year or after maximum 250.000 tightening de-
pending on which occurs sooner. More frequent overhaul may be
needed, if used at high torque and long tightening times. If the
machine not is working properly, it should immediately 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 accurately and de-
fective or worn parts (i.e. O-rings, vanes) should be replaced.
