Occupational safety and general remarks according to DIN EN 133311/2 Lifting, handling, pulling, dragging Handling should e carried out as close to the ground as possile Slings (chain type and thickness, load hooks) must e chosen to suit the weight eing handled (eg trench ox or slide rail) To prevent the accidental detachment of the load during lifting, pulling or handling, only load hooks with safety catches may e used Particularly when pulling loads, the pulling forces defined in section 7416 in DIN EN 13331/1 must e oserved The load must e slung in such a way that the shoring is in a horizontal position and swinging during handling is reduced to a minimum The shoring must e lowered onto level and firm ground It is prohiited to stand within the pivoting range of the excavator/crane and eneath suspended loads A load operator may only stand to the front left of the excavator, in constant eye contact with the machine operator It is always prohiited to stand within the danger zone Oserve the industrial safety ordinance and the accident prevention regulations for lifting gear Measures to reduce hazards The safety of vehicles and persons on site must e ensured with the aid of cones, warning tape or safety staff specially deployed for this purpose The construction site should e sufficiently marked as such with the aid of warning signs, for instance Technical contents are suject to change Pulishing date 15/01/2013 The risk of instaility as a consequence of wind loads when setting up the shoring on the edge of the trench must e considered The shoring should e secured against accidental impacts and set up in a sufficiently stale position (sufficient width and firm ground) When handling, installing and removing shoring, watch out for overhead power cales On sloping or uneven ground, the shoring should e set up if possile at right angles to the slope Usage instruction edgesupported shoring units E+S 5

Reasons for taking parts out of service and instructions for repair Before use, all shoring components must e checked for their correct function Reasons for taking worn or damaged parts out of service include: Missing parts, such as nuts, screws, posts, pins and stailizers Broken parts such as spindles, pins and spreader systems in general If parts are severely deformed or misshapen or if there are holes in panel odies, for instance, the manufacturer should e consulted in cases of dout Faulty parts must e replaced or repaired Minor repairs can e carried out y the user, after consultation with the manufacturer Only original replacement parts from the manufacturer may e used There is no warranty on incorrectly performed repairs and the use of nonoriginal parts The requirements of the industrial safety ordinance apply In all cases of dout, always consult the manufacturer Procedure in the event of an accident In the event of an accident, casualties must e given first aid immediately The scene of the accident must e cordoned off and left unchanged If the injured person is expected to e unfit for work, an accident insurance doctor must e consulted All accidents must e reported immediately to the superior or his deputy The accident must e entered in the accident record ook The currently valid versions of the following documents apply: Provisions of the Civil Engineering Committee of the Accident Insurance Institution DIN 4124 "Baugruen und Gräen" (pits and trenches) DIN EN 13331, Part 1: Product Specifications, Part 2: Assessment y Calculation or Test General safety instructions and the relevant industrial safety ordinances Our products ear the "Geprüfte Sicherheit" (GS) quality seal During installation, the instructions contained in the manufacturer's manual must e referred to and oserved Technical contents are suject to change Pulishing date 15/01/2013 6 Usage instruction edgesupported shoring units E+S
