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 com-
pleted. 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.
