Cleaning the taPe Path
2. 1
CL EA NI NG T HE T AP E PA TH
It is important that the tape path is clean before
adjustments are made. If the heads and guide posts
have been adjusted, the tape path must be de-
magnetized.
Cleaning should be carried out with cotton-bud
sticks (Q-tips) moistened with pure alcohol or
methylated spirit. A special cleaning kit called
"Tandberg Professional Tape Head Cleaner" is
also available.
Aerosol sprays indented for video tape recorders
may be used, but it is not sufficient just to spray
the parts; cotton-bud sticks must also be used.
Obstinate deposits on guide posts should be first
well softened with the cleaning agent and then
removed with the aid of a toothpick.
The pinch roller A should be cleaned if the tape
runs unevenly or if there are visible deposits on
the roller (4 to 6 times a year should be sufficient,
even if the tape recorder is much used). Make sure
that the pinch roller is dry after cleaning.

NOTEI Do not usc more than one drop of oil on
each bearing, as excessive oil may penetrate into
the drive mechanism and disturb friction conditions.
The turntables, flywheel and transfer wheel are
mounted in selflubricating bearings and should not
need attention under normal conditions. If for
some reason lubrication appears to be necessary,
use Teresso oil No 43 or 47 from Esso.
The motor should be lubricated after every
3000 hours of operation. Apply only one drop of
Teresso oil No. 43 or 47 from Esso.
