4 Operation
Unless otherwise requested the driver is preset to max. torque with the
strongest clutch spring.
Adjust clutch to the required torque value. If necessary, exchange clutch
spring. The necessary torque adjustment can be tested, using a DEPRAG
Torque Wrench or Measuring Platform (see
DEPRAG catalogs D 3020 and
D 3022 ). This equipment can also be used to re-adjust the torque of the
Screwdriver Spindle.
Operating the clutch using a clutch spring which exceeds
its allowable torque, leads to a reduction of the torque
accuracy.
The driver starts by remote-valve.
The flow pressure should not drop below 5 bar (71 PSI)!
The installation and connection of the Screwdriver Spindle requires the
following steps:
1. Adjust clutch to required torque setting (see paragraph: Torque
Adjustmen t)
2. Install Screwdriver spindle according to picture „ Installation Tips for
screwdriver spindle “.If several Spindles are being installed, refer to the
screwdriver arrangement on construction sheet (if you do not have this
construction sheet, please call us).
3. Connect main air hose.
4. Connect pneumatic function control hose. This function control is under
pressure of 2,5 bar during actual screw-driving. If the function control
is not needed, the port has to be closed, otherwise there is a loss of
power of about 15 %.
Please make sure not to exceed the max. screwdriver stroke (see
Installation Tips for screwdriver spindle ) during Screwdriving. The noise level
can be further reduced, when an exhaust connection with connected
Filter/Silencer is used.
