Service Notes

1-1. Chemicals

Handle chemicals with care. Store them sealed in a cool, dry place away from direct sunlight. Minimize the number of small containers for chemicals to reduce evaporation. Keep containers sealed when not in use. Use chemicals sparingly, dispensing only the required amount for immediate use.

1-2. Exterior Parts

Use cleaning paper or cloth for cleaning exterior parts. Avoid using chemicals like thinner, ketone, or alcohol. When installing exterior parts, insert screws vertically and do not overtighten.

1-3. Unleaded Solder

This unit uses unleaded solder. Boards using unleaded solder are marked with the lead-free mark (LF). When soldering, set the soldering iron tip temperature to approximately 350°C. Solder and unsolder quickly to prevent damage to the printed circuit board. Be cautious of solder bridges. Use separate soldering irons for leaded and unleaded solder to prevent mixing.

1-4. Safety Check-out

After repairs, perform safety checks: inspect for unsoldered or poorly-soldered connections, check wiring for pinching, identify unauthorized replacement parts, check for deteriorated components, and verify B+ voltage. Ensure all parts, screws, and wiring are returned to their original positions. Flexible circuit board repairs require careful temperature control (around 350°C) and limited contact with the same conductor.

Disassembly

2-1. DISASSEMBLY

Detailed instructions and diagrams are provided for the disassembly of the lens, including notes on removing the Outer Barrel Assy and Operation Barrel Assy. Specific tools like the Universal Wrench and service tools such as adhesive bond are mentioned.

Note for Repair: Ensure flat cables and flexible boards are not cracked or bent. Do not insert cables insufficiently or crookedly. When removing or installing connectors, do not pull or press the wire. Avoid applying excessive load to gilded flexible boards.

Universal Wrench: Used for disassembling/assembling lens blocks with specific notches or holes. It requires specific chips (Chip-A for notches, Chip-B for holes).

Service Tools: Adhesive bond (B-60) is listed.
