How to use

Position the hose cutting pliers so the hose is centered in the cutting jaws, apply steady pressure to close the handles and slice through the hose in a controlled motion. For clean cuts, stabilise the hose close to the cutting zone and use a single smooth cutting action without twisting. After cutting, inspect the hose end and, if necessary, trim any uneven edges with a repeat controlled cut. Keep hands and other body parts clear of the cutting area during operation.

Recommendations

Use the pliers only on materials within the tool’s intended range: rubber and plastic hoses. Avoid cutting metal-reinforced hoses or other hard materials that can damage the cutting edge. Clean and dry the tool after use and store in a dry place to minimise corrosion. If cutting thicker or abrasive hoses frequently, consider periodic sharpening or professional servicing to maintain cutting performance.
