DESCRIPTION
The speed of the drive engine (1) can be infinitely varied by remote control on the throttle control lever (8).
The upper (4) and lower (5) masses are connected to each other by 4 vibration-damping rubber metal shock
mounts (14). This damping system prevents the very high frequencies from being transmitted to the upper
mass (4). As a result the functionability of the drive engine (1) is retained in spite of the high compaction per-
formance.
The drive engine (1) works on the diesel principle; it is started electrically by a pinion starter (3), draws in the
combustion air through an air filter, dry (9) and is air-colled.
To facilitate the starting procedure (at very low temperatures, with hand start) the drive engine (1) has an au-
tomatic decompression mechanism (2). It ensures that compression is very low during the cranking operation
but steadily increases after a few revolutions when it then switches over to full compression.
