Tightening of threaded connections
The tightening torques indicated in the exploded views list are established to achieve the correct clamping
force and preventing the parts from coming loose. At service these parts must be able to open up without
being destroyed. In special circumstances (depending on application and usage) the parts may however
come loose after some time of operation. In such cases the torque could be increased 10-20% and if nec-
essary some type of low or medium threadlocking fluid could also be applied.
Example
Operating Instructions
Air pressure monitoring, RE-signal S1
Reporting pneumatic assembly tools provide a pneumatic signal that indicates which part of the tightening
cycle the tool has reached, by means of variations in air pressure.
In the RE-Controller box timers are triggered when certain pressure levels are reached.
Pressure level 1 (P1) starts a timer that checks that the tightening cycle is not too short.
Pressure level 2 (P2) starts a timer that checks the time taken from when the clutch has been released to
when the operator releases the trigger to ensure that it is not too short.
The controller measures the differential pressure over the motor.
It should be noted that the system does not measure torque! Regular check of installed torque/torque out-
put of the tool must be done separately.
