How to use

Select the appropriate pliers and position the tips inside the internal circlip, ensuring secure contact with the circlip ends.

Inspect the seating to confirm the circlip rests fully in the groove.

Usage recommendations

For safe and effective operation, check the pliers for wear or damage before use, especially at the tips. Use hand protection as needed and avoid applying excessive force beyond the specified application range. Store the pliers clean and dry to maintain the oil-hardened steel condition.
