2. Description
The machine The machine is a hand-guided, reversible soil compactor.
The machine is composed of a bottom and a top section.
The bottom section houses the exciter, while the top section
contains the engine and the required controls.
An air-cooled Hatz diesel engine makes the exciter vibrate
via a centrifugal clutch. The generated force is transmitted
between top and bottom section via a V-belt.
The engine is started electronically by a permanently installed
start module.
The engine speed is adjusted between idle speed and full-
throttle speed via a gas lever.
Forward and reverse travel is variably controlled with a handle
via a hydraulic system.

4. Safety
General All safety instructions must be read and complied with, as non-
compliance will result in
- Danger to life and limb of the user,
- Impairments to the machine or other
property.
In addition to the operating manual, the accident-prevention
regulations in the country where the appliance is used must be
complied with.
Intended use The machine should only be used in technically faultless
condition, as intended, in a safety-conscious and hazard-
conscious manner, and in compliance with the instructions in the
operating manual.
Malfunctions that may impair safety require that you stop
working with the machine immediately. These types of damage
must be reported and corrected without delay.
The machine is designed exclusively for compacting:
- Sand,
- Gravel,
- Crushed rock,
- Low-cohesive mixed material,
- Paved surfaces.
The operator's work position is behind the machine.
The operator must guide the machine safely with both hands on
the handle.
Non-intended use Unless used as intended, the machine involves a risk of

avoid damage to the engine. If the engine fails to turn over
after no more than 30 seconds, turn the ignition key back to
the “0” position and eliminate the cause.
If the ignition key fails to spring back to position “1” by itself,
the electric starter and the engine may sustain damage. Abort
the start procedure and shut down the machine. Identify and
rectify the cause before the next start attempt.
During operation Monitor the surroundings to avoid injury to third parties or
material damage.
Suspend operation and shut down the machine if detecting
damage on the machine during operation.
Stop operation and shut down the machine if the light
indicators of the start module do not go out shortly after startup
or come on during operation.
The symbol is lit permanently during operation. It signals
that the engine is running. Refer to the section “Operation” for
the exact meaning of the individual light indicators.
Parking the machine Alwaysparkthemachineonalevelsubsurfacewithsu󰀩cient
bearing capacity.
Parked machines presenting an obstacle must be secured in
accordance with statutory regulations, particularly in the area
ofpublictra󰀩csurfaces.
Engine and exhaust heat up during operation and can cause
burns on contact. Therefore, do not touch these components
duringoperationorshortlyafterthemachinewasswitchedo󰀨.
Fueling the machine Spilled fuel may ignite and has a negative impact on the
environment. Therefore, wipe up spilled fuel and make sure
thegascapisrmlytightenedafterfueling.

The COMPATROL compaction control system
1 Operational status indicator
(Green)
This indicator comes on as soon as the proper operating
frequency has been reached and signals that the compaction
control system is operational.
Iftheindicatorashesconstantly,themachineisoperating
with the wrong operating frequency.
2 Compaction indicator
(Yellow)
The LEDs 1-7 indicate the achieved level of soil compaction.
The number of lit LEDs increases with the level of compaction.
If no additional LED comes on after another pass over the
same spot, the maximum level of compaction has been
reached.
3 Warning light (Red) The warning light warns of operation on soils that are too hard.
These types of soil cannot be compacted further with the
machine type used and may result in damage to the machine.
Figure 4

19
The attainable maximum may vary with the type and composition of the
soil. On sand, the maximum is commonly reached at a low number of lit
LEDs.
Following the compaction of a mix of gravel and crushed rock that is
uniformly graded and contains the proper concentration of water, the
indicator is likely to show six to seven lit LEDs.
It is important to closely monitor the indicator during the last pass. Places
where the number of lit LEDs drops sharply are poorly compacted. In
these places, the soil needs to be compacted again or may even have to
be replaced.
Possible indicator states
Function test of the LEDs A function test of the LEDs is performed when the ignition is
turned on, but the engine has not yet been started.
The operational status indicator (1) and the warning light (3)
light up permanently.
The LEDs of the compaction indicator (2) light up in
succession from left to right and go out in reverse order.
After engine start, before
reaching the operating
frequency
The warning light (3) signals by lighting up permanently that
the compaction indicator is not operational yet.
The LEDs of the compaction indicator (2) are not yet lit.
Theoperationalstatusindicator(1)signalsbyashingthatthe
operating frequency has not been reached yet.
Reaching the operating
frequency, operation
Upon reaching the operating frequency, the operational status
indicator (1) lights up permanently, indicating that the machine
is ready for operation.
The warning light (3) goes out.
The compaction indicator (2) starts lighting up, indicating the
achieved level of soil compaction.
Illumination of the warning
light
The warning light warns of operation on soils that are too hard.
If all LEDs of the compaction indicator (2) are lit together with
the warning light (3), the soil to be compacted is too hard.
Stop operation immediately to avoid damage to the machine.
