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 Honda gasoline 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 impair safety must be eliminated without
delay.
The machine is designed exclusively for compacting:
– sand,
– coarse gravel and gravel grain with a grain size
of 63 mm in accordance with ISO 14688,
– crushed rock,
– low-cohesive mixed material,
– concrete paving stone.
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, non-compactable soils,
– compacting non-bearing material,
– compacting rocks with a grain size of 63 mm,
– compacting highly cohesive soils,
– point loads on the base plate,
– crushing rocks.
The responsibility for any damage arising from non-intended
use falls on the owner / operator rather than the manufacturer.
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 opera-
tors who are of legal age. 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 trac 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 modied
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 aect 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 suocation 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 20 seconds to
avoid damage to the engine. Pause for at least one minute
before repeating the start procedure.
If the engine does not start after two start procedures,
look for the cause in the fault table.
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 indica-
tors 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 sucient
bearing capacity.
Parked machines presenting an obstacle must be secured in
accordance with statutory regulations, particularly in the area
of public trac 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.
10
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.
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.
Maintenance Maintenance and repairs require specic qualications. These
operations may only be carried out by trained professionals.
There is an increased risk of injury during maintenance
and repairs, e.g. crushing at moving parts.
Following the conclusion of all maintenance and repairs,
all protective xtures must be retted and placed back into
operation.
Discharged operating uids have a negative impact on the
environment. They must be collected and stored in suitable
containers. Disposal in accordance with environmental
protection regulations.
Before starting the machine after maintenance operations,
make sure that all loose parts (screws, tool, etc.) have been
removed from the machine. They may be drawn in or ung o
by moving parts.
Keep the entire machine clean. The stickers must always be
clearly legible. Damaged stickers must be replaced.
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 lubri-
cants 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 briey, can cause unconsciousness and death.
Therefore, never inhale the exhaust gas.
