How to use

Select the correct orientation of the pliers for internal or external circlips, place the inserted tips into the circlip holes or ends, and apply steady pressure to expand or compress the circlip as required. Keep the bolted joint aligned and operate with controlled motion to avoid sudden releases. After use, clean any debris from the tips and store the pliers in a dry place to preserve the oil‑hardened steel.

Recommendations

For safe and long-lasting performance, use the pliers only on circlips within the tool's intended size range, avoid excessive bending of the tips, and inspect the inserted tips regularly for wear. Do not use the pliers as a hammer or pry tool.
