How to use

Select the appropriate circlip plier orientation for internal or external rings and position the tips into the circlip holes or onto the ring ends. Squeeze the handles evenly to expand or compress the circlip as required, then carefully place or remove the ring from the shaft or bore while maintaining steady alignment. Release the pressure slowly to avoid sudden movement of the circlip and inspect the ring and mating surface for correct seating.

Usage recommendations

Use appropriate eye protection when working with circlips. Keep the tips clean and free of nicks; do not use the pliers as a general prying tool. For long service life, wipe off grease and debris after use and store the pliers in a dry place to preserve the corrosion-resistant finish.
