Unless maintenance is properly carried out, the following service intervals may be quite shortened as harmful effects may be had on other parts. Also, long term storage or misuse may cause transformation and aging of rubber parts. Time Parts Name Audio Control Head Full Erase Head Loading Motor Belt Reel Belt Pinch Roller Capstan DD Unit Loading Motor Tension Band Capstan Shaft Tape Running Guide Post Cylinder Unit : Replace : Clean Replace when rolling becomes abnormal. 500 hours 1, 000 hours 1, 500 hours 2, 000 hours 3, 000 hours Notes Clean those parts in contact with the tape. Clean the rubber, and parts which the rubber touches. CLEANING NOTE After cleaning the heads with isopropyl alcohol, do not run a tape until the heads dry completely. If the heads are not completely dry and alcohol gets on the tape, damage may occur. Dip it in isopropyl alcohol and clean the audio control head by wiping it horizontally. Turn the cylinder head counterclockwise to clean it (in the direction of the arrow). (Refer to the figure below) NOTE Do not exert force against the cylinder head. ) · When you activate the deck without the Front Loading Unit 15, short circuit between TP1001 and TP1002. Set the master plane (JG022) and reel disk height adjustment jig (JG024) on mechanism framework, taking care not to scratch the drum, as shown in Fig. Confirm that the reel disk is lower than "A" of the reel disk height adjustment jig (JG024) on the master plane and higher than "B" as shown in Fig. If it is not, adjust to less than 7. 5mm±0. 2mm with the height adjustment washer. Perform the same adjustment for other reel. Master Plane (JG022) Reel Disk Height Adjustment Jig (JG024) 1-2: CONFIRMATION AND ADJUSTMENT OF TENSION POST POSITION 1. Turn on the power and set to the PLAY mode adjust the Tension so that the Tension Post is at the position of 0. 3mm~0. 5mm from the Rib. Confirm that the video tape is not curling at the flange of P1 post or is not running on flanges. P1 Post Tension Post Tension Arm P0 Post Rib Reel Disk (S) Tension Adjust Fig. After adjustment, confirm and adjust the tension post position (Refer to item 1-2) for the tension arm, install the cassette type torque tape (JG100A) and set to the PLAY mode. Confirm that the left hand side tension value of the torque tape is 25~38gf·cm for the standard mode tape.
