Key risks

• Cuts and punctures from the exposed blade edge.
• Slips and loss of control, especially with dull edges or slippery surfaces.
• Flying splinters or fragments from the material or from a damaged edge, posing an eye hazard.
• Impacts and rebound when using an unsuitable mallet or hammer, or striking outside the intended area.
• Breakage or detachment of the handle or blade due to wear, cracks or misuse.
• Damage when encountering nails, staples or other foreign objects hidden in the workpiece.
• Injuries caused by dropping the tool or by carrying it without a protective sheath.

Safe use

• Inspect before use: secure handle, tight ferrules, blade free of cracks or deformation, and an intact cutting edge.
• Secure the workpiece with clamps or stops and work on a stable, clear and well-lit surface.
• Keep hands and body out of the cutting line; make short, controlled strokes, always cutting away from yourself.
• Keep the edge sharp; a dull edge requires more force and increases the risk of slipping.
• Use only the type of mallet or hammer recommended for the model, and strike only on the designated area.
• Before chiselling, locate and remove nails, staples or other metal elements in the work area.
• Wear eye protection; consider cut-resistant gloves for handling and transport, avoiding bulky gloves during cutting if they reduce feel and control.
• Carry the chisel with a sheath and the blade pointing downwards; do not carry it in pockets.
• Stop work if you notice play, unusual vibrations or loss of control.

Storage and maintenance

• Clean and dry the tool after use to prevent corrosion; apply a light protective film to the edge if appropriate.
• Store cutting edges with sheaths or guards and separate from other tools to prevent nicks and accidental cuts.
• Store in a dry, ventilated place, away from moisture and heat sources.
• Sharpen periodically using methods appropriate to the tool type; carefully remove burrs and nicks.
• Replace cracked or loose handles and discard blades with cracks or deformations that cannot be safely repaired.
• Check that the striking end (if fitted) is not cracked or deformed; discontinue use if damaged.
• Keep workbench clamping systems in good condition for safer control.

Restrictions of use

• Do not use the chisel as a lever, punch, screwdriver or for tasks it is not designed for.
• Do not work on materials incompatible with the tool, nor strike it with non-recommended tools.
• Do not use the tool if it shows play, advanced corrosion, a heavily nicked edge, or absence of a sheath during transport.
• Do not modify the tool (heating, filing or shortening it excessively) if this could compromise its strength or control.
• Do not work near exposed live conductors or on unstable surfaces, or on ladders without the workpiece being firmly secured.
• Keep out of reach of children; minors only under competent adult supervision.
