14.1 Head and transport cleaning

The DA-98 incorporates an internal cleaning mechanism that not only cleans the rotary head, but also the tape as it enters the tape path. The pro- vision of this cleaning mechanism significantly reduces the need for manual cleaning. If, despite the internal cleaning mechanism, the

TION indicator (page 2-1) lights, the heads are dirty and manual cleaning procedures should be followed.

Use a TEAC HC-8 cleaning tape (recommended) or a dry cleaning tape specially designed for Hi8 8mm video equipment.

WARNINGS

NEVER use a wet-type cleaning tape, as this will result in winding problems.

The use of the dry tape will reduce the head life of the DA-98 by about five hours. Use of manual cleaning is therefore discouraged.

We recommend the following schedule (based on our experience with the DTRS system) for clean- ing and maintenance schedules. See 14.1.3, “Checking head time” below for details of how to check head usage time.

Every 350 to Perform manual cleaning of heads and

400 hours guides as described below. Check the tape path alignment after cleaning. This requires proper test and measure- ment equipment, and should be per- formed only by qualified service personnel.

Every 1000 A complete alignment check should be

NOTE

Most name brand tapes are of very high quality. How- ever, it is sometimes possible to receive “bad” stock which exhibits execssive shedding characteristics. If you receive such tape stock, stop using it immediately, and followSel01234567theectleaningMprocedenuGre as describedroupbelow.
