Page 103: Whole-Body Vibrations
Operating techniques Whole-body vibrations Whole-body vibrations Whole-body vibration emission on construction machinery are affected by a number of factors, such as working mode, ground conditions, speed, and so To a large extent the operator can influence the actual vibration levels, because the operator controls the speed of the machine, its working mode, the travel path, and so on.
Page 104 Operating techniques Whole-body vibrations - Transport machines when there are long distances between worksites. Back pain associated with whole-body vibrations may be caused by other risk factors. The following guidelines can be effective to minimize risks of back pains: - Adjust the seat and controls to achieve good posture.
Page 105: Rules For Digging
Operating techniques Rules for digging Rules for digging WARNING Risk of serious injury. More than one person in the cab while operating could cause accidents and serious injury. Only the operator, seated in the operator’s seat, may be in the cab when operating. All other persons must keep at a safe distance from the machine.
Page 106: Working Within Dangerous Areas
Operating techniques Working within dangerous areas Working within dangerous areas Observe great care at marked danger areas. Do not operate too close to the edge of a quay, ramp, ditch and so on. Move slowly when working in confined spaces and check that there is sufficient room for machine and load.
Page 107 Operating techniques Working within dangerous areas operator at fairly great distances from the power line. Voltage Minimum distance to power line 0 ~ 50 kV 3 m (10 ft) 50 ~ 69 kV 4.6 m (15 ft) 69 ~ 138 kV 5 m (16.4 ft) 138 ~ 250 kV 6 m (20 ft)
Page 108 Operating techniques Working within dangerous areas - All other persons should keep away from the machine, ropes, and load. - The operator should try to remove the machine from contact by moving it in the reverse direction from that which caused the contact. - If the machine cannot be moved away from contact, the operator should remain inside cab until the lines have been de-energized.
Page 109 Operating techniques Working within dangerous areas Working on slopes WARNING Risk of tipping over. When working on uneven slopes and ground the machine can tip over. Make sure the maximum machine inclination is not exceeded and that the inclination angle is not increased by an obstacle.
Page 110 Operating techniques Working within dangerous areas If the electric motor shuts down on a slope, lower the attachment to the ground. Do not operate the swing function since the superstructure may swing under its own weight and cause tipping or side slipping.
Page 111 Operating techniques Working within dangerous areas Working where there is risk of landslip Always check ground conditions before beginning to work. If the ground is soft, great care must be taken when positioning the machine. Thawing of frozen ground, rain, traffic, piling and blasting are factors which increase the risk of landslip.
Page 112 Operating techniques Working within dangerous areas Working in cold weather WARNING Risk of frostbite. Bare skin can freeze stuck to cold metal which could cause injury. Use personal protective equipment when handling cold objects. NOTE! The hydraulic system could respond slowly at low temperatures.
Page 113 Demolition work Before the machine is used for demolition work, additional front and top protective guards needs to be installed. For further information contact a Volvo Construction Equipment dealer. Be extremely careful and study the work site thoroughly. Use fall protection over the cab against falling objects.
Page 114: Attachments
The machine has either direct- mounted attachments or attachments mounted in a hydraulically controlled bracket which allows rapid changes of attachments. Always follow Volvo Construction Equipment recommendations when choosing attachments. If other attachments are used, follow the operator’s manuals from the respective supplier.
