PERIODIC MAINTENANCE
To properly maintain the CHRISTIE CHRISTIE 35/70 Automatic Electronic Projector and avoid damage to the film, a certain
amount of routine preventive maintenance is required. Proper maintenance aids in preventing untimely system
breakdowns. This section describes the appropriate maintenance procedures.
Maintenance procedures are performed at daily, weekly, monthly, six-month (semiannual), or yearly (annual) intervals, as
well as when the lamphouse bulb is replaced. Tables 4.2 through 4.7 list the periodic procedures. CHRISTIECHRISTIE
recommends that these tables be photocopied and used as preventive maintenance checklists and logs.
Do not use any film lubricants on the 35/70 projector!
Equipment Required for Preventive Maintenance
Table 4.1 lists equipment that should be available in the projection booth. It should be easy and convenient for the
projectionist to perform any required maintenance. If the proper tools are not at hand, it is unlikely that the maintenance
will be performed as directed.
