How to Use / Care & Maintenance
Insert the terminal and stripped wire into the appropriate crimp cavity. Squeeze the handles until the ratchet mechanism completes the cycle and releases. Inspect the crimp to ensure that both insulation and conductor crimps are properly formed. After use, clean off debris, store in a dry tool case and occasionally apply a drop of light machine oil to keep the ratchet smooth. Avoid dropping the tool to protect alignment.
