• Rollers VH250/270/300/350 are tandem vibration rollers with articulated frames and two smooth drums. Both drums are hydrostatically driven and vibrating. The vibration of the rear drum may be switched on and off. All functions of the machine are controlled by hydrostatic motors. The frames are designed to allow for soil compaction close to walls and curbs on both sides of the machine. Their small dimensions and turning radius make the machine suitable for work in limited areas.
• The operator’s station permits perfect visibility of both rims of the drums. The combined rollers VH250K and VH300K with front vibration drum. The two hydromotors drive and brake the rear axle with four smooth tyre.
• The roller should be used under conditions defined in the Czech Standard (CSN) IEC 721-2-1 (038900): WT, WDr, MWDr, i. e. in mild, dry warm and dry hot weather in the range of temperatures from -15 °C (5 °F) to 45 °C (113 °F).
• This machine is manufactured to the latest developments and standards, which secure its safe function. If the machine is used incorrectly, by untrained operators or for other purpose than stipulated above, there is a danger of an accident or damage to the equipment.
• The main purpose of this manual is to give information necessary for carrying out assembly and disassembly of the
  machine as well as service repairs of main assemblies of the equipment. It contains technical and installation data,
