Warning and instruction signs

Preventing heat build-up close to pressure systems Preventing heat build-up in lines carrying combustible fluids

Heat generation close to pressurized fluid lines may result in a highly flammable spray, putting you and other persons in the immediate vicinity at risk of serious scalding. Never carry out heat-generating welding or soldering work close to pressurized fluid lines or other highly flammable substances, and never use a flame cutter there. Pressure lines may be inadvertently cut if the heat goes beyond the immediate flame area. To provide temporary protection for hoses or other materials, mount fire-resistant shields when carrying out welding or soldering work. - Never carry out welding or flamecutting work on pipes or lines carrying combustible fluids. - Flush them out with a non-flammable solution before welding or flame-cutting them.

Removing paint before welding

Hazardous fumes may develop if paint is heated by welding, soldering or the use of a flame cutter. These fumes may affect your health if inhaled. - Avoid inhaling potentially toxic fumes and dust. - Carry out such work only in the open air or on well ventilated premises. - Paints and solvents must be discarded in accordance with local environmental regulations. Remove paint prior to welding or heating: - When rubbing down paint, avoid inhaling the dust. - Wear an approved respiratory mask. - When using a solvent or paint remover, remove the agent with soap and water before any welding operations. Remove all solvent or paint remover containers and other inflammable materials from the working area. Give the fumes at least 15 minutes to dissipate before any welding or heating.

Risks from breaking-away components

The tyres are inflated under pressure Bursting tyres and breakingaway rim parts may cause serious damage or fatal accidents. - Tyres must be changed by experts only. - Always ensure that the tyre pressure is correct. Insufficient tyre pressure means greater wear on the tyres and poor machine stability. - Excessively high tyre pressure means poor handling properties on terrain and a risk of bursting tyres. - Prior to inflating tyres, check rims and rim components for damage, penetrating foreign bodies and a firm fit. - Never inflate tyres above the recommended pressure. - Leave tyres to cool down before working on them. - Use only compressed ambient air to inflate tyres. Never use combustible gases: risk of explosion. Use appropriate tools

Use only tools suited to the respective work. Inappropriate tools, components and procedures may result in hazardous situations. Use tools whose length is suitable for the tightening or loosening of safety elements to prevent injuries resulting from failure to control a wrench. Never use tools complying with US standards or British standards for metric connection elements. Use original spares only (see spareparts catalogue).
