1. PUTTING INTO SERVICE
Supervise the compressed air duct.
Use the ducts, accessories and connectors in good state and adapted to the working effective pressure
fixed by the manufacturer.
Make sure the working pressure is not superior to 6.3 bars and inferior to the recommended pressure
during the screwdriver rotation. An excessive pressure will result in an accelerated tool damage.
Make sure that the tool exhaust is not clogged and that the tool is correctly fixed to the suspension device
if you use one.
Keep a safe headway so that any tool normal reaction while functionning doesn’t bound surrounding
elements and especially during the unscrewing.
Use the most often possible carriers or reaction bars judiciously placed.
Be careful with the risk of snapping up of clothes, hairs, etc... by the rotary spindle during the putting into
service of the tool.
Remove the hands of the tool turning part.
Make sure the ensambly caracteristics correspond to the tool performances.
Do not over-charge your tool. Check and respect the power range and the recommended working
pressure.
2. GENERAL INSTRUCTIONS
Your screwdriver must be used cautioustly ; do not let it fall down or make impacts on it.
It is recommended to establish a preventive maintenance programm in order to avoid numerous repairs
and to preserve the optimal performances of your tool.
Before any intervention on the tool, switch off the tool from the compressed air network. Have your tool
repaired by a qualified technician.
The use of spare parts no sold by your provider may bring a decrease of performances and cancel all
warranties towards the manufacturer.
When the noise level at the working place is superior to 85 dB(A), it is recommended to use auditory
protectors.
Tool noise level : see the luggage lable.
Do not use a portable tool in explosive atmosphere.
3. PNEUMAT 103 LIMITER FUNCTIONING
The mentioned marks are indicated on the exploded view.
The tightening torque at the extremity screwdriver involves a torque reaction on the motor body (25)
which tends to make the body turn in the opposite direction.
A torsion spring (43A) limits the angular bottoming proportionally to the output torque.
A cam system constituted of a ball (49) and of the cam (42) involves the central dumper displacement
(45) releasing the valve rod wich close instantaneously and stops the motor by air shut-off.
The journal (50) adjustment by the blocking screws (43B) and adjusting screws (43C) permit to vary the
spring angular bottoming amplitude.
This kind of limiter only works in the screwing sense.
The screwdrivers equipped with 103 type limiter are torque control tools with a torque adjusting system
which cuts the tool power as soon as the torque reaches a preadjusted level.
4. STARTING LEVER ORIENTATION WITH REGARD TO THE HEAD
The indexing of the angle head and of the screwdriver is made by cylinder Ø 4X4.
Untighten the nut (21).
Adjust the neck (22) by positioning the cylinder (23).
Retighten the blocking nut (tightening torque of 40Nm).

5. TORQUE ADJUSTMENT
Adjustment procedure :
Before any adjustment to the utilized torque, look for the position corresponding to the minimum torque.
Let the screwdriver turn in free rotation in the fastening sense and after having untightened the blocking
screw (43B), turn the adjusting screw (43C) in the negative sense (anticlockwise) until the screwdriver
stops.
Release the lever and activate one more time the lever : the screwdriver musn’t turn.
Turn the adjusting screw in the clockwise direction by
half turn and activate the lever at each phase : when
the screwdriver starts, the adjusting torque
corresponds to the minimum torque.
Proceed to the standstill torque value control by
inserting a rotary transducer between the screwdriver
and the tightening socket in accordance with the 5393
ISO standard procedure.
Change the adjustment until obtaining the desired torque by taking up the adjusting screw play before to
unscrew the clamping screw.
We advise you to act on this screw only by succesive half-turn and to make a control after each adjusting
modification.
Do not make any adjustment on a retightening.
After each intervention on the adjusting screw (43C), retighten moderately the blocking screw.
6. UTILISATION CAUTION FOR CROWFOOT NUTRUNNERS
The nutrunners equipped with crowfoot require a particular care. The train of gears wich permits to make
screwings in hard-to-get to zone, is often proportioned in function of the ensambly working environment in
unusual conditions.
In certain cases where numerous pinions are necessary inside the crowfoot, the train of gears reversibility
is not systematic. We advise you against practising a traction on the screwdriver when it has reached its
screwing torque (after locking due to the limiter). It could bring about a retightening of the ensambly, or if
this action was repeated a premature breaking of the crowfoot or of its pinions.
7. ASSEMBLY AND DISASSEMBLY RECOMMENDATIONS
At each disassembly, clean and study carefully all the spare parts before to proceed to the gears and ball
bearings regreasing.
Lubricate lightly the blade housings in the moment of the motor reassembly.
Use only appropriated wrenches. Do not use vice tightening and multiple slip-joint pliers.
Warning :
The presence of a cutting kerf on a nut symbolize a threading on the left. It is recommended to
disassembly frecuently the exhaust silencers and to clean them with a spray gun after having soak them
in a degreasing agent solution in order to preserve the original caracteristic of the tool.
8. LUBRICATION
Unless otherwise stated, pneumatic tools must be feeded with filtered and lubricated air.
It is recommended to install the lubricator the nearer possible of the tool especially during the screwdriver
utilisation. It is also recommended to watch over to the good functionning and to the oil supply adapted
adjustment.
After a prolonged locking, introduce by the feeding connector some crude drops or clean gas oil drops.
- turn the motor in manual by actionning the output spindle.
