compaction machines that are specially designed to
compact medium to deep layers of granular soils in
limited areas, such as trenches, parking lots, and
foundations among other areas. No other use is
permitted.
With a block paving kit they are also suitable for
block paving applications.
MV compactors must only be used in well ventilated
areas, as is the case with all combustion engine
machines.
The MV compactor must not be towed behind
vehicles.
Do not operate on steeper slopes than
recommended in this manual.

Filling procedure
1. Stop the engine and let it cool down before
filling the tank.
2. Release the filler cap slowly to let any pressure
escape.
3. Fill the fuel tank to the lower edge of the filler
pipe.
4. Never overfill the tank. Due to the movement of
the fuel within the tank, it is possible to have fuel
at a higher level than the tank cap, which can
lead to a spillage of fuel if the tank cap is opened.
This can be avoided by only opening the tank
cap, when the machine is tilted and the tank cap
is at the fuel tank's highest point.
