Vibratory Single Drum Roller VM 115D/PD/HD (Instruction Manual)

BASICS

1. Vibratory Single Drum Roller VM 115D/PD/HD is built according the state of the art and in accordance with the recognized safety rules. Nevertheless, its use can cause danger to life and limb of the user or third parties or damage to the machine and other material assets.

2. Use the machine only when it is in technically perfect condition. Use it in the manner for which it was intended. Be aware of safety measures and possible hazards. Always observe the instruction manual. In particular, immediately eliminate faults which could impair safety (or have them eliminated).

3. The machine is intended only for compacting beds of earthy building materials when running over the subgrade in the forward or reverse direction with or without vibration. These building materials include soil types ranging from stones to silty sand and having water contents ranging from 40% to 110% of the optimum water content according to the standard Proctor test as given in DIN 18127.

Fine–grained soils or soils having higher water contents require a qualified trial compaction. Vibratory Single Drum Roller VM 115D/PD/HD is intended to be used only on a subgrade gradient up to the permissible gradient.

Definition of grade ability

The grade ability of a roller is the gradient angle of a firm, hard and level roadway on which a roller of the basic–equipment version with its longitudinal axis pointing in the incline direction can start in the forward and reverse directions by means of its own propulsion and then travel further for a short period.
