SERVICE PROCEDURES
3-1 PRECAUTIONS
1. El Kl SSL/ESL-series projectors have been designed for the ultimate in simplicity, and ease
of service and repair. Each screw is very important, and when servicing or reassembling the
projector, screws should not be omitted or carelessly lost. All screws should be firmly
tightened to assure reliable projector operation after disassembly.
2. When lubricating the projector's plastic parts, silicone oil or grease should be used. Other
types of lubricants may harm plastic parts.
3. El Kl projectors require a minimum of special tools. The most important is an ordinary ISO
Phillips screw driver set.
4. To avoid damage to screw heads it is important to remember the adage "70% push, 30%
turn." It is also important to select the right size screw driver blade. A rule of thumb is to
use the largest blade possible.
5. To avoid possible electrical shock, always disconnect the projector from the power source
when servicing.
3-2 TOOLS AND TEST EQUIPMENT
A. Tools:
When servicing El Kl SSL/ESL-series, ordinary ISO (Phillips type) screw drivers and single-
bladed screw drivers should be enough. (El Kl Screw Driver Kit, P/N 5615 are available.)
A Molex extractor tool is most useful when replacing the pins of nylon connectors to
transformer or motor.
B. Special Tools:
El Kl SSL/ESL-series have been designed so that no special tools should be required to
service the projector. However, several special tools are available to speed up adjustments
and maintain a closer consistency between the projectors.
