4 Operation
Unless otherwise requested the driver is preset to max. torque with the
strongest clutch spring installed on the clutch. Adjust clutch to the required
torque value. If necessary, exchange clutch spring. The required torque
adjustment can be checked, 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.
To operate the clutch, using a clutch spring which either
surpasses or falls below its specified torque range, leads to a
reduction of the torque accuracy.
NOTICE
The screwdriver is furnished with a reversible motor and a
clutch torquing out in right-hand rotation (so that if you look
at the screwdriver from the air inlet side it rotates clockwise).
Push – to – start – screwdriver.
The flow pressure should not drop below 5 bar/71 PSI - reduced output!
