DJUSTMENT
Separate the nutsetter from the air supply!
-
Prevent rotation of the hydraulic rotor <73> using a wrench size
SW19 (3/4").
-
Using a screwdriver SW4 turn the valve screw <81>
counterclockwise until stop; this corresponds to minimum torque
adjustment.
-
By turning the screw approx. 0 to 4 revolutions clockwise, adjust
the desired torque (160 to 250 Nm).
-
If the pulse interval is < 4, reduce the speed. This is done by
turning the exhaust air throttle <3>. First the set bolt <8> must be
loosened with a wrench size SW2.
-
Turn exhaust air throttle toward "-", the speed is reduced.
Caution!
Caution!
Do not adjust the speed below 1800 rpm, since the idling
speed may otherwise fluctuate.
