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
personal injury and property damage. The machine is
expressly not suitable for:
– compacting frozen subsurfaces,
– compacting hard soils that cannot be compacted
further,
– compacting non-bearing material,
– compacting highly cohesive soils,
– compacting (ramming) that exerts point loads on
the base plate,
– crushing and compacting individual rocks.
The responsibility for any damage arising from non-intended
use falls on the owner / operator.
Non-intended use or misuse will void all liability and
warranty claims.
Residual risk There is always an increased risk of accidents in the
immediate danger area around the machine if the operator
fails to notice persons in the vicinity of the machine.
Anyone close to the machine must be made aware of this risk.
The operator must not put the machine into operation unless
everyone in the vicinity of the machine is aware of this risk.

8
Requirements on the operator This soil compactor may only be operated by suitable
operators who are 18 years or older. They must be instructed
on how to operate the machine by the owner or by the owner’s
assigned personnel. The operator must comply with tra󰀩c
regulations.
The machine must not be operated by children.
Personal protective
equipment
Personal protective equipment consisting of
– hard hat,
– hearing protection,
– protective gloves,
– work shoes or boots with toe guard
must be worn during operation and the execution of
maintenance on the machine.
Danger areas The immediate danger area is the direct perimeter around
the machine. This area is o󰀨-limits to third parties.
Spare parts, changes
and conversions
Changes and conversions are prohibited unless made with
original Weber MT spare parts. If the machine is modied
with other accessories without the approval of Weber MT,
the manufacturer will not assume liability for any resulting
personal injury or property damage.
All maintenance and repairs must be carried out with original
Weber MT spare parts. Untested spare parts may a󰀨ect
the reliability and safety of the machine.
Before starting the machine There is danger of material damage if the machine is
started before necessary maintenance or repairs have been
completed. Make sure every time before starting the machine
that all work on the machine has been completed.
To avoid injuries, the machine must not be started unless the
operator wears the required personal protective equipment.
Objects placed on top of the machine may fall or be ung o󰀨
during operation or when the machine is started. Therefore,
remove all loose objects or tools before starting the machine.
If the gas cap is open, fuel may escape and ignite on the
engine when the machine is started or while it is operating.
There is a risk of burns. Therefore, do not start the machine
unless the gas cap is closed.

9
Start-up procedure Do not disperse any sprays or other agents into the air intake
while the machine is starting up. They may lead to overheating
in the combustion chamber and result in damage to the engine.
There is danger of su󰀨ocation if the operator starts up the
machine in closed rooms or in deep and tight trenches.
Operating the machine in closed rooms is prohibited. Provide
for an adequate supply of air before starting the machine.
One start procedure must not last longer than 30 seconds
to 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.

10
When coming into contact with fuels, the rubber-bonded metal
bu󰀨ers of the machine may become damaged or ine󰀨ective.
Therefore, wipe spilled fuel carefully o󰀨 the rubber-bonded
metal bu󰀨ers.
Fuel vapors are easily ammable. Do not smoke and
keep away from open re while refueling the machine.
The machine must not be fueled unless the engine is
switched o󰀨.
Cleaning work Use clear water for cleaning. Do not use ammable solvents.
The vapors of the solvents may ignite upon contact with hot
components or other sparks.
Perform cleaning tasks only in rooms that are suitable and
have been approved for that purpose. Residual oil and
lubricants that may have been rinsed o󰀨 have a negative
impact on the environment and must be collected by suitable
means (e.g. oil separator).
Safe handling of combustion
engines
Combustion engines pose a particular risk during operation.
Their exhaust emissions contain carbon monoxide, a colorless
and odorless gas that is extremely hazardous, which, if inhaled
even briey, can cause unconsciousness and death.
Therefore, never inhale the exhaust gas.
Inspection The machine must be inspected in accordance with the corre-
sponding implementation conditions and operating conditions
to ensure its operationally safe status. This inspection should
be performed as needed by an expert – however, no less than
once a year. The ndings of the inspection must be stored in
writing until the time of the next inspection.

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 reach-
ing 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.
