Greenlee CU/AL Cutter Jaw for EK425/EK628 Series Tools

Professional Performance and Maintenance Guide

The Greenlee CU/AL Cutter Jaw is an essential component for professionals utilizing the EK425 and EK628 series. To ensure peak performance and longevity, we recommend the following professional maintenance practices:

Optimizing Cutting Efficiency

To maximize the clearance and prevent handle interference during full-stroke operations, ensure the tool is positioned perpendicular to the cable. For larger diameter conductors, verify that the cable is fully seated in the jaw cradle before initiating the cut to maintain optimal blade alignment.

Material Longevity and Usage Tips

While these blades are rated for standard 2/0 aluminum and 600MCM copper, we advise regular inspection for debris. To prevent blade chipping or sticking, avoid cutting beyond the rated capacity and ensure the blades are kept free of metal shavings. Periodic lubrication of the pivot point is essential for smooth operation.

Structural Integrity and Safety

For the pivot mechanism, we recommend a routine check of the captive screw assembly before every job. Applying a small amount of thread-locking compound can help maintain bolt tension during high-frequency use. Additionally, ensure handle grips are fully seated and dry before operation to maintain maximum control and safety on the job site.
