2. Safety Information

Always observe the following safety precautions to prevent personal injury and damage to the cleaver.

• Eye Protection: Always wear appropriate eye protection when handling optical fibers and operating the cleaver. Fiber shards are extremely sharp and can cause severe eye injury.
• Sharp Blade: The cleaver contains an extremely sharp blade. Exercise extreme caution when handling the blade or performing maintenance. Keep fingers clear of the blade path.
• Fiber Shard Disposal: Dispose of all fiber shards properly in a designated fiber waste container. Do not leave shards exposed on work surfaces.
• Clean Environment: Operate the cleaver in a clean, dust-free environment to prevent contamination of fiber ends and internal mechanisms.
• Authorized Personnel: Only trained and authorized personnel should operate and maintain this equipment.

5. Operating Instructions

Follow these steps for a precise fiber cleave.

1. Prepare the Fiber: Strip the fiber coating to the required length (typically 30-40mm) and clean the bare fiber with an approved fiber cleaning wipe and isopropyl alcohol.
2. Open the Cleaver: Lift the top cover of the cleaver. This will typically open the fiber clamp and position the blade for cleaving.
3. Place the Fiber: Carefully place the prepared fiber into the V-groove. Ensure the bare fiber extends beyond the cleaving blade and aligns with the measurement scale for the desired cleave length.

4. Secure the Fiber: Close the fiber clamp (if not automatic) to gently hold the fiber in place.

5. Perform the Cleave: Close the top cover of the cleaver. This action will automatically initiate the cleaving process, scoring and breaking the fiber.
6. Remove Fiber: Once the cleave is complete, open the top cover. Carefully remove the cleaved fiber.
7. Dispose of Waste: Ensure the cleaved fiber end (waste) is deposited into the integrated fiber waste bin.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your cleaver.

• Blade Cleaning: Periodically clean the cleaver blade and surrounding areas with a lint-free swab and isopropyl alcohol. Ensure no fiber debris accumulates.
• V-Groove Cleaning: Keep the V-groove clean from dust and fiber particles. Use a soft brush or compressed air.
• Blade Rotation: The S326 features an automatic blade rotation. If cleave quality degrades, it may indicate the blade needs to be rotated to a new position or replaced. Refer to the blade rotation mechanism instructions (if applicable to your specific S326 variant) or contact support.
• Blade Replacement: When all blade positions have been used, the blade must be replaced. This is a delicate procedure and should only be performed by trained personnel or a service technician. Always use genuine Fitel replacement blades.
• General Cleaning: Keep the exterior of the cleaver clean with a soft, dry cloth. Avoid using harsh chemicals.
