Make sure that the temperature sensors of the fire alarm and extinguishers system do not come in contact with the hot cleaning fluids, which could trigger the fire extinguishing system. Remove all coverings and masking material after completing the cleaning procedure. Then check all fuel lines, engine oil lines and hydraulic oil lines for leaks, loose connections, chafing and / or damage. Fix any problems immediately. operator and / or must be in direct voice contact with the operator. When working overhead, use appropriate and safe ladders, scaffolding or other working platforms designated for that purpose.
Never step on parts or components on the machine when maintaining or repairing items overhead. When working high above ground, make sure you are fitted with ropes and appropriate safety devices which will prevent a possible fall. Always keep handles, steps, railings, platforms and ladders free of dirt, snow and ice! If you use a high pressure cleaner with steam or hot water to clean the machine, observe following recommendations : the distance between the nozzle and the surface to be cleaned must be no lower than 20 inches When working on the attachments, for example when replacing the bucket teeth, makes sure the attachment is supported properly. Never use metal on metal support!
the water temperature should not exceed 60°c (140°F) For safety reasons, never open and remove a track chain unless having previously totally released the pretension of the chain tensioning unit. limit the water pressure to 80 bar maximum (11500 PSI) if you employ cleaning fluid, only use neutral cleaning agents such as customary car shampoos diluted to 2 or 3 percent maximum Never work underneath the machine if it is raised or propped up with the attachment. The undercarriage must be supported with wooden blocks and supports. Never employ high pressure cleaning apparatus during the two first months following machine delivery or repainting.
Always support the raised machine in such a way that any shifting to the weight change will not influence the stability. Do not support the machine with metal on metal support. Observe all product safety guidelines when handling oils, grease, and other chemical substances. Only qualified, especially trained personnel may work on travel gear, brake and steering systems. Make sure service fluids and replacement parts are disposed of properly and in an environ- mentally sound manner. If it becomes necessary that the machine must be repaired on a grade, block the chains with wedges and secure the uppercarriage to the undercarriage with the lock pin.
When using hot service fluids, be very careful. (They can cause severe burns and injury!). Operate combustion motors and fuel operated heaters only in well ventilated areas. Before operating these units, check ventilation. In addition, always follow applicable local regulations. Only qualified, especially trained personnel may work on the hydraulic system. Never check for leaks with your bare hands, always wear gloves. Fluid escaping from a small hole can have enough force to penetrate the skin. Never try to lift heavy parts. Use appropriate lifting devices with sufficient load carrying capacity.
When replacing or repairing parts or components, make sure they are mounted very carefully on lifting devices, to prevent any possible danger. Use only suitable and technically sound lifting devices, make sure that lifting tackle, wire cables, etc. has adequate load carrying capacity. Never position yourself, walk or work underneath suspended loads. Never loosen or remove lines or fittings before the attachment has been lowered to the ground and the engine has been turned off. Then turn the ignition key to contact position with tilted down safety lever, move all servo controls (joysticks and foot pedals) in both direction to release pressures.
Then release the tank pressure as outlined in this Operation and Maintenance Manual. Always disconnect the battery cable before working on the electrical system or before any arc welding on the machine. Always disconnect the negative (-) cable first and reconnect it last. Never use damaged lifting devices, or devices which are not sufficient to carry the load. Always wear gloves when handling wire cables. Ask only experienced personnel to attach loads and guide and signal the crane operator. The guide must be within the visibility range of the 2.9
