Safety Manual
The safety manual, which accompanies each machine, must be studied by each operator of the roller. Always follow the safety rules and do not remove the manual from the roller.
GENERAL
This manual contains instructions concerning operation and use of the roller. For information regarding care and maintenance, see the manual, ”MAINTENANCE, CC 722/C".
When starting up and driving a cold machine, which implies cold hydraulic fluid, the braking distance will be longer than normal until the machine reaches normal working temperature.
California
Proposition 65 Warning
Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.
SAFETY INSTRUCTIONS (Also read the safety manual)
WARNING
1.The operator must be familiar with the contents of the OPERATION MANUAL before starting the roller.
2.Make sure that all instructions in the MAINTENANCE MANUAL are followed.
3.Only trained and/or experienced operators may drive the roller. Passengers are not allowed on the roller. Remain seated during all operation.
4.Never use the roller if it is in need of adjustment or repairs.
5.Board and leave the roller only when it is stationary. Use the grips and railings that are provided. Always use a ”three-point grip” - both feet and one hand or one foot and both hands - when boarding or exiting the machine.
6.The ROPS (Roll Over Protective Structure) should always be used when the machine is operated on risky ground.
7.Drive slowly in sharp bends.
8.Avoid driving at an angle on slopes; drive straight up or down.
9.When driving close to unsafe edges or holes, make sure that at least two thirds of the drum width is firmly on material that has already been compacted.
10.Make sure that there are no obstacles in the direction of travel, on the ground or overhead.
11.Drive extra carefully on uneven ground.
12.Use the safety equipment provided. The seat belt must be worn on machines fitted with ROPS.
13.Keep the roller clean. Clean dirt and grease from the operator’s platform without delay. Keep all signs and decals clean and clearly legible.
14.Safety measures before refueling: – Stop the engine. – Do not smoke. – No naked flame in the vicinity. – Ground the nozzle of the filling device against the tank to prevent sparks.
15.Before repairs or service:
– Place chocks against the drums/wheels and against the strike-off blade. – Lock the articulation if required.
16.Hearing protectors are recommended if the noise level exceeds 85 dB(A). The noise level may vary depending on what material the machine is operating on.
17.Make no changes or modifications on the roller that could affect safety. Changes may only be made following written consent by Dynapac.
18.Do not use the roller until the hydraulic fluid has reached its normal working temperature. Braking distance can be longer than usual if the fluid is cold. See starting instructions in the OPERATION MANUAL.
Safety When Driving
Driving near an edge
When you drive near an edge, at least two thirds of the drum width must be on solid ground.
WARNING
Remember that the machine’s center of gravity is displaced outward when you steer to one side. For example, it shifts to the right when you steer to the left.
Slopes
WARNING
The ROPS (Roll Over Protective Structure) is always recommended when driving on slopes or insecure ground.
WARNING
Where possible, avoid all driving across a slope. Instead, drive up and down on sloping ground.
The tilting angle is measured on a hard, level surface with the machine stationary, steering angle zero, vibration switched OFF and all tanks full. Remember that loose ground, steering of the machine, vibration switched ON, driving speed and raising the center of gravity (for example, with accessories) may cause the machine to topple even on a smaller slope than that stated here.
WARNING
If you have to leave the cab in an emergency, use one of the doors or the front window, which can be opened.
SAFETY (OPTIONAL)
Air conditioning
The system contains pressurized refrigerant. Releasing refrigerants into the air is prohibited. The refrigerant circuit may only be repaired by an authorized company.
The cooling system is pressurized. Incorrect handling can result in serious personal injury. Do not disconnect the hose coupling.
Recharge the system with approved refrigerant when required.
SAFETY DECALS, LOCATION/DESCRIPTION
Crush zone, articulation/ Drum. Maintain a safe distance from the crush zone.
The operator is urgently requested to read the safety manual, and the operation and maintenance instructions before using the machine. (Two crush zones on machines fittedwithpivotalsteering.)
Warning - rotating engine components. Keep your hands at a safe distance from the danger zone.
Warning - rotating parts. Maintain a safe distance from the crush zone.
Warning - hot surfaces in the engine compartment. Do not touch.
Toxic gas. Read the instruction manual.
Study the towing chapter before disengaging the brakes. Danger of being crushed.
Machine And Engine Plates
Machine plate
Please state the PIN (serial number) of the roller when ordering spares.
The serial number of the frame (1) is punched on the right edge of the forward frame.
The engine data plate (1) is on the crankcase below the air cleaner on the right side of the engine. The plate indicates the type of engine, serial number and engine data. Please state the engine serial number when ordering spares. See also the engine manual.
