How to use

Select the wrench with the appropriate jaw size for the fastener, then open or close the jaw by turning the thumbwheel until the jaws fit snugly against the flat faces of the nut or bolt. Position the wrench so the load is applied to the fixed jaw where possible to reduce slippage. Apply controlled force and avoid sudden impacts; readjust the jaw as needed when working in confined spaces. After use, clean any debris from the threaded thumbwheel and store the wrenches in a dry place.

Recommendations

Use the wrenches within their intended jaw range and avoid excessive leverage by using the correct size from the set. For fine adjustments and to prevent damage to fastener edges, ensure the jaws are fully engaged on flat surfaces. Regularly inspect the thumbwheel and jaws for wear, and keep the tools clean and lightly lubricated to maintain smooth adjustment.
