3. Torque Adjustment
Separate the nutsetter from the air supply!
- Prevent rotation of the hydraulic rotor <61> using a wrench
size SW19 (3/4").
- Using a screwdriver SW4 turn the valve screw <63> counter-
clockwise until stop; this corresponds to minimum torque
adjustment.
- By turning the screw approx. 0 to 4 revolutions clockwise,
adjust the desired torque.
- For the bottom torque range you may have to reduce the
speed additionally. 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.
