To obtain full function and maximum performance from
the set, and to stop it getting dirty or scratched, we
recommend that you carry out the following maintenance
procedures and regular checks. The maintenance checks
described in the following section should also be carried
out without fail after carrying out any repairs to the set.

• Always use the specified brands of oil and grease. If you

use a grease with the wrong viscosity, for example, this
can lead to all sorts of problems. Be careful to keep the
oil and grease free of dust and foreign bodies.

• A “drop” of oil is the amount of oil remaining on the tip of

a rod with a diameter of 1.5mm after it is dipped in oil to
a depth of 1cm and then taken out.

Moisten a chamois with methyl alcohol and clean the video

relation to the video head. If you wipe vertically, or use
excessive force, you can damage the video head.

Clean the pinch roller, the capstan shaft, the tape guides,
the FE head, the ACE head, the reel table, the pulley and
the reel belt with a soft cloth, or chamois, moistened with
methyl alcohol.
