How to use

Select the jaw opening by turning the adjustment mechanism until the jaws match the size of the nut or bolt. Position the wrench so the fixed jaw bears against the flat side of the fastener, then turn the handle to tighten or loosen. For work with hand taps, use the wrench to hold or guide small components as required. If necessary, unscrew the handles for storage or replacement following the manufacturer's instructions.

Inspect the jaws before use to ensure they are not excessively worn; avoid applying excessive torque beyond the tool's size rating. Store the spanner in a dry place to reduce corrosion risk and keep the adjustment mechanism clean for smooth operation.
