C 4.74 Operating instructions Operating instructions Safety General notes on safety Work clothing • • • • • • • • • • • Observe your national regulations on safety and health protection. Do not allow children under 16 to use the vehicle. When using the public highway, respect the highway code. Do not allow anyone to stand around where they might get hurt. Do not run the engine in enclosed spaces. Exercise extreme caution when handling fuels - there is a high risk of fire.
Operating instructions C 4.74 Operating instructions • • - - - The installed equipment must conform to the applicable EMC directive 89/336/EU and carry the CE symbol. If you must install a mobile communications system (or have it installed) (eg radio, mobile phone), the following requirements must be met: Only approved equipment (ie with type approval) may be installed. The equipment must be installed firmly.
Operating instructions C 4.74 Operating instructions Hydraulic oil, brake fluid During operation, these fluids are pressurized and pose a health hazard. Do not spill these fluids. Remove any spilled fluids immediately with oil binding agent and discard them. Discard drained fluids as specified. Observe applicable laws and regulations. Do not allow them to come in contact with hot engine parts. Danger of fire! Avoid contact with the skin. Avoid the inhalation of spray fog.
Operating instructions C 4.74 Operating instructions Particularly the particles contained in the exhaust gas can cause cancer. For this reason the engine should not be operated in enclosed spaces. Heat The exhaust gases are very hot and can ignite inflammable material. The exhaust gas pipe should therefore be kept away from ignitable materials. Battery During charging, the battery produces a mixture of oxygen and hydrogen (detonating gas). This mixture of gases is explosive and must not be ignited.
