manual will help avoid hazards, reduce repair and downtime
costs and will increase the reliability and operational readiness
of your machine. Follow these instructions precisely.
This operating and maintenance manual must always be kept
at the implementation site of the machine and be available to
the machine operator.
Enclosed with this manual is a valid declaration of conformity
and a spare parts lists for orders of spare parts. Store these
documents carefully.
If you require any additional information, turn to your
Weber MT dealer.

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
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
assignedpersonnel.Theoperatormustcomplywithtrac
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.Thisareaiso-limitstothirdparties.
Spare parts, changes and
conversions
Changes and conversions are prohibited unless made with
originalWeberMTspareparts.Ifthemachineismodied
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
WeberMTspareparts.Untestedsparepartsmayaectthe
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.
Objectsplacedontopofthemachinemayfallorbeungo
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.
Thereisdangerofsuocationiftheoperatorstartsupthe
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 Alwaysparkthemachineonalevelsubsurfacewithsucient
bearing capacity.
Parked machines presenting an obstacle must be secured in
accordance with statutory regulations, particularly in the area
ofpublictracsurfaces.
Engine and exhaust heat up during operation and can cause
burns on contact. Therefore, do not touch these components
duringoperationorshortlyafterthemachinewasswitchedo.
Fueling the machine Spilled fuel may ignite and has a negative impact on the
environment. Therefore, wipe up spilled fuel and make sure

Cleaning work Useclearwaterforcleaning.Donotuseammablesolvents.
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
lubricantsthatmayhavebeenrinsedohaveanegative
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
evenbriey,cancauseunconsciousnessanddeath.
Therefore, never inhale the exhaust gas.
Inspection The machine must be inspected in accordance with the
corresponding implementation conditions and operating
conditions to ensure its operationally safe status. This
inspection should be performed as needed by an expert
-however,nolessthanonceayear.Thendingsofthe
inspection must be stored in writing until the time of the next
inspection.
