How to use

Position the hook jaw onto the outer edge or slot of the retaining ring, collar or round fastener so that the hook fully engages the component. Apply steady torque by turning the handle in the required direction to tighten or loosen the fitting. For best control, maintain firm grip and use smooth, even force; avoid sudden jerks. Inspect contact points before use to ensure the hook is seated correctly and the component will not slip during operation.

Usage recommendations

Use appropriate personal protective equipment and ensure the workpiece is secured before applying torque. Avoid using the spanner on damaged or excessively worn fittings to prevent slippage. Regularly inspect the tool for wear or deformation and replace if compromised. Store the spanner in a dry place to maintain the corrosion-resistant finish and prolong service life.
