Hints on Labour Safety

- Use gloves when handling larger sheet metal plates - risk of getting injured.

- Only use proper and sharp shears - blade clearance must be adjusted correctly.

- Do not work with jour hands between the blades - risk of getting injured.

- Only let one person operate lever shears and guillotine machines, as for large-size sheets and long sections, a second person may help push them through from the side.

- Correctly adjust the toe dog on lever shears and shearing machines.

- Do not stay within the swiveling range of hand levers during the cutting operation.

- Secure hand lever of the lever shear after the cutting process.

- Only shear steel sections with section knives - never operate on sheets with plane shear blades, otherwise the cutting edges break off.

- Only operate shearing machines after being exactly instructed. Exactly observe the manufacturer’s operating instructions.

- Immediately throw the waste material rendered during the shearing operation into the waste container. Remaining bent rests of cuts may lead to injuries.
