5 Setup and function16 100_0202_sf_0006.fm5 Setup and function5.1 Standard packageThe machine is delivered fully assembled and is ready for operation out of the box.The standard package includes: Vibratory plate Starting crank (optional) Operator's manual5.2 Application areasThe vibratory plate is used for compacting soil. It is used in gardening and landscaping as well as civilengineering, road construction, and paving.5.3 Short descriptionThe vibratory plate is a machine used to compact soils.The vibration required for the compression is generated by the exciter firmly connected to the base plate.This exciter is designed as a centrally mounted exciter with single-plane vibrations. Such a principleallows for a modification in the vibration direction by turning the eccentric weights.A variable transition between compression in travel speed, on the spot compaction and in reverse travelis therefore possible. This process is controlled hydraulically with the control handle on the center polehead.The drive motor attached to the upper mass drives the exciter. The torque is firmly transferred throughthe centrifugal clutch and the exciter V-belt.At low engine speeds, the centrifugal clutch interrupts the force flow to the exciter and thereby allows aflawless idling of the drive motor.The automatic v-belt pulley combined with the centrifugal clutch ensures an optimal tension of the exciterV-belt during operation and for relief of the exciter V-belt during offsetting or during transport of themachine.In addition, the automatic v-belt pulley automatically adjusts to the wear of the V-belt edges and thusmakes the entire drive system from the engine to the exciter maintenance-free.The drill speed of the drive motor can be variably adjusted by remote control on the throttle lever andlocked into the idle position. The upper mass and base plate are connected to each other by 4 vibrationabsorbing rubber metal buffers. This attenuation prevents a transmission of the very high frequencies tothe upper mass. The functionality of the drive motor therefore remains preserved, despite the highcompaction performance. The drive motor works according to the diesel principle, is electrically startedvia a gear and pinion starter, draws the combustion air through a dry-type air cleaner and is air-cooled.To facilitate the starting process (when very cold, during manual start), the drive motor has adecompression automation system. This causes the compression to be very low when starting to turn,but to steadily increase after a few revolutions to then switch to full compression.Operating hour meter (optional)On the operating hour meter, the operating hours of the machine can be accurately read, therebyallowing for better observance of the maintenance intervals.Extension platesFor larger working areas, additional mounting plates are recommended.Compatec – compaction display (optional):The Compatec compaction display is attached to the battery cover and is within the operator’s line-of-sight. The display, which consists of eight light-adjusting LEDs, displays the relative compactionprogress by successively lighting up. When the number of illuminated LEDs no longer increases, thismeans that no further compaction can be achieved with the machine. The operator can finish the workand avoid unnecessary passes or over-compaction of the soil.The overload display indicates if the machine is being operated on too hard of a surface. The operatoris notified of this through rapid flashing of all eight LED's.Compatec – compaction display is suitable for all highly compactable and mixed-grained soils.
