Service Instructions
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 spe-
cial circumstances (depending on application and usage) the parts may however
come loose after some time of operation. In such cases the torque could be in-
creased 10-20% and if necessary 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 output of the tool must be done separately.
