Setup, Compatibility & Care
To achieve the best results, use the thumb screw at the base of the handle to adjust the jaw distance until the pliers require firm pressure to lock shut. Always ensure the teeth are properly seated on the object before fully engaging the locking mechanism to prevent slippage.
Regarding care, keep the hinge and locking mechanism free of heavy grit or metal shavings by periodically wiping the tool with a shop rag. A light application of machine oil on the pivot points will maintain smooth operation. Store in a dry environment to ensure the chrome-plated surface retains its protective integrity over many years of service.
