Page 7: Machine Description
1.2 Machine Description The CR 7 CCD soil compactors are machines of the walk-behind type used for compaction work in road construction and landscape applications. Propulsion The CR 7 soil compactor is driven by a Lombardini Diesel engine. Important! Please refer to paragraph 1.3 (Specifications) for the performance details of the engine and the whole machine. -
Page 8: Description Of The Compatrol
1.2.1 Description of the COMPATROL Compaction Control System COMPATROL is a continuous compaction control system for soil compactors of the walk-behind-type. The system can be used on soils of the “V1” class (well compactable soils). The COMPATROL compaction control system consists of an acceleration sensor (2/2) fitted to the base plate (2/1) and of the Compaction Control Display (CCD) (3/2) integrated in the dashboard (3/1). - Page 9 When the operating frequency is achieved, the green LED (6/ 1) and at least one of the yellow LEDs (6/2) will light up to indicate that the COMPATROL system is ready for work. Figure 6 During the compaction process, the compaction achieved is continuously measured and optically indicated by the yellow LEDs 1 to 7 (7/8/1).

Page 14: Pre-Start Work
2.4 Pre-Start Work Check to ensure that all safety devices are in place. Check the whole soil compactor for evident damage (visual check). Check all screwed connections for tight seat, retighten them if necessary. Check the fuel level, if necessary, add fuel (refer to paragraph 2.4.1). Check the engine oil level, if necessary add engine oil (refer to paragraph 2.4.2). -
Page 15: Checking The Engine Oil Level
2.4.2 Checking the Engine Oil Level Caution! The engine oil level must be checked with the soil compactor standing horizontally on the ground. Pull out the oil dipstick (16/1), wipe it off with a clean, non- fluffing cloth and insert it again. max. -

Page 17: Starting
2.5 Starting Danger! Before starting the machine, always ensure that nobody is in the danger area of the soil compactor and that all protective devices are properly in place. When starting the soil compactor in closed premises, always ensure a proper ventilation - danger of poisoning. Caution! Figure 20 Never use starting aid sprays! - Page 18 When the engine has been started, the LEDs (23/1) will light up until the correct frequency is reached. As soon as the correct vibration frequency is reached, the red light-emitting diode (23/2) will be extinguished. If the red LED (23/2) does not go out, please refer to paragraph 4.2 “Trouble Shooting“.
