Only start the machine from the drivers seat. As soon as an attachment part is removed and supported, cover or cap the openings in the hy- draulic circuit to prevent dirt infiltration. Travel down grades at the appropriate speed to maintain control of the machine. Record the values of the achieved tightening torque and the additional angle of rotation. For travel, move the uppercarriage parallel to the undercarriage and hold the load as close as pos- sible to the ground.
The following practices and precautions should be observed: Match your travel behaviour to the changed machine characteristics and surrounding conditi- ons. For that reason, always guide the door by hand when opening the door. Position the uppercarriage to the undercarriage in such a way that the steps and ladders are aligned. In some illustrations, protective devices and covers have been removed in the interests of better presentation. The number of screws to be tested depends on the total number of screw connections and is normally between 1 and 3 see also section 6. Never start a machine before completing a thorough walkaround inspection.
Specific attention should be given to the following: The steel structure undercarriage with axle and gear mounting, support, lower slewing ring seating with tower and slewing ring. Do not steer, brake, accelerate and shift or move and load the attachment of the machine in a jerky manner. Definitions: Pretightening torque: The piston rod bearing is secured with a torque wrench applied to the square of the assembly wrench. Apply a mark on the screw head that is aligned with a mark applied on the component see figure 4. Always wear safety glasses and protective gloves when handling batteries.
The torque values have been determined empirically and are subject to changes. Example: In addition to a pro- tective helmet and safety boots, for certain jobs protective goggles and gloves are also necessary. Keep hands, tools and any other objects away from contact with the cooling fan. Move the machine only after you have taken on the load, lifted it and turned the uppercarriage in travel position. The machine operator and his staff are allowed to carry out certain jobs, but other jobs must be carried out only by qualified and trained staff.
It contains the descriptions for: Chapter 1 Product description Chapter 2 Safety guidelines Chapter 3 Control, operation Chapter 4 Malfunctions Chapter 5 Maintenance The operating instructions must be read and used carefully by all persons who carry out work with or on the machine before putting the machine into service for the first time and later, at regular intervals. Set the machine on a level and stable ground prior to any work with attachments. This symbol indicates a result of an action. If so required to the job site conditions, ensure, that you have appropriate windscreen protection. The revision and release dates indicate the latest version of the factory standard. When swinging a load, first bring the attachment as low and close to the machine as practical. Potholes and uneven road sur- faces endanger the stability of the machine.
Avoid wearing rings, wat- ches, ties, scarves, open jackets or loose clothing. Figure 3 A: Dial B: Adjusting screw C : Angle scale Before tightening, set the dial A with the adjusting screw B to position 0° on the angle scale C. For more information, see lubrication chart and inspection and maintenance schedule. Prior to any welding, cutting or grinding, clean the machine and surrounding area to remove dust and flammable materials. To drive out a pin, install the impact screw from the tool box in the threaded bore of the pin and hit the screw only. In horizontal direction, the centre of gravity of the uppercarriage is above the cen- tre of the undercarriage, which improves stability.
Towing equipment must have sufficient tensile strength and must be attached to the undercarria- ge at the designated tiedown attachment points. If possible, always work downhill or uphill, never sideways on a slope. For such connections, the required tightening torques assembly torque, angle of rotation must be determined individually by the technical department. Remove excess grease along the thread length. The working sequences when working with machines with grapples require a properly instructed and trained operator. If the machine must be repaired on an incline, block the track chains with chocks and secure the uppercarriage to the undercarriage with the locking pin. Carefully take the machine to an open area and check all control functions.
Observe the required clearance distances to any underground utilities. At or near operating temperature, the engine cooling system is hot and under pressure. When replacing hoses and lines on movable parts e. Position the uppercarriage to the undercarriage in such a way that the steps and ladders are aligned. The different load conditions result in different service lives for various machi- nes components. Lubricate the machine and change the oils at the prescribed intervals.
