If a light grease is applied, be careful not

11、 to get any grease on the play/record head or erase head, hubs, pulleys, tapes reels, drive belts, or switches. Use a good lubricant such as Silicon Lube G322L or Lubricate. Service Check Before aligning the mechanism, wipe off any accumulated dirt with denatured alcohol. Wipe around parts where the

12、 tape contacts and around all rotating parts. Drive belts are specially processed. Do not clean them with alcohol. Mechanical Torque Use a cassette type torque gauge and check the tape mechanism. Take-up torque 35 to 70 g-cm Rewind torque 50 g-cm min. Fast forward torque 50 g-cm min. Pinch Wheel Pre

13、ssure No adjustment to the pinch roller spring is necessary. It should be sufficient to give at least 40 g-cm pull force. Tape Head Servicing Each time the unit is serviced, the face of all heads should be thoroughly cleaned with denatured alcohol or commercial head cleaning solution. The playback h

14、ead should be demagnetized with a commercial demagnetizer. Accumulation of tape oxide during normal operations can cause problems, including loss of high frequencies and wow and flutter. Erase Head The erase head is properly aligned when the tape rides directly between the tape guide on the head wit

15、hout crinkling the tape. Play/Record and Playback Head Azimuth Adjustment To adjust the play/record and playback head azimuth screw: 1. Connect two (2) VTVMs and a dual trace scope to the stereo headphone jack (as shown) with a 32 ohm dummy load. (See Figure 1.) VTVMVTVM DUMMY LOAD JK400 SCOPE CH1 C
