PUTTING INTO OPERATION

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.
Take into account the tool reactions while functionning and be sure to be able to contain
the pressure at the end of the screwing.
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 assembly caracteristics correspond to the tool performances.
Do not over-charge your tool. Check and respect the power range and the recommended working
pressure.
Only use sockets and screwing accessories made to be used on machines.

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 not 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 .

93 TYPE PNEUMAT LIMITER FUNCTIONING

The items are the one of the exploded view. The tightening torque on the screwdriver extremity
involves a reaction torque on the collar (56) of the last epicycloid reduction train which lend
to make the collar turn in the contrary sense.
A torsion spring (69) limits the angular bottoming proportionally to the output torque.
A came system constituted of 3 balls (65) and 3 housings (71) involves the moving of the central
trigger circuit (61). The clack valve rod closes instantaneously and stops the motor by air shut - off.
The came adjusting (71) by blocking screws (79) and adjusting screws (81) permits to fluctuate
the angular clearance amplitude, acting like this on the tightening final torque.
This type of limiter only works in the tightening sense (or untightening if it has been specified on
the order).
During a contrary rotation, the applied torque is the one corresponding to the tool maximum
capacity. The screwdrivers equipped with the RT limiter are torque control tools with a torque
adjusting system which cuts the tool power feeding as soon as the torque has reached a
preadjusted determined level (paragraph 3.15/NF 5393 ISO).
