2.2.1 Cleaning
Periodic cleaning of the tape transport system is desirable, but
usually not feasible in practice. Therefore,perform cleaning
when a set is brought in for repairs or maintenance. Con-
tamination of the video heads,tape guides and brush can
detract from playback picture quality and in extreme
cases,even damage the tape.For cleaning,use a finemesh
cotton clothiabout the texture of a white dress-shirt) mois-
tened in alcohol. It is recommended to also clean thetape
tension posts and capstan.
*
To clean the video heads, press the moistened cloth
gently against the upper drum with fingertip and turn the
drum by hand.
¢
Do not use a vertical stroke,as this may damage the
heads.
2.2.2 Lubrication
Oil and grease do not normally require periodic replenishing.
Apply only when replacing lubricated partslaiso clean and
replace lubrication of mating parts if soiled). For parts and
points to apply oil and grease, refer to the exploded views
of the mechanism assembly. Before oiling,clean with alcohol.
Apply one or two drops of oil. Avoid excess oil.
