3.2 Description and purpose of the machine
This machine is a portable power source. The portable generator from PRAMAC
consists of a frame, which includes a fuel tank, a gasoline engine, a control panel
and an electrical alternator. The control panel contains controls and bushings.
When the engine is running, the generator converts the mechanical energy into
electrical energy. The operator connects electronic loads to the mains sockets.
This machine is used for the electric power supply of connected electric loads. See
the product specifications for output voltage and frequency of the generator as well
as the maximum power limitation of this generator.
This machine was designed and built exclusively for the afore mentioned purpose.
Use of the machine for any other purpose could permanently damage the machine
or cause serious injury to the operator or other persons in the vicinity. Machine
damage due to misuse is not covered by the warranty.
The following practices are considered misuse:
▪Connection to an electric load whose voltage and frequency are not
compatible with the generator output
▪Overloading the generator with a load that takes too much power during
continuous operation or when starting
▪Operating the generator in a manner that is inconsistent with the national,
statewide and local standards and regulations
▪Use of the machine as a ladder, support or working surface
▪Operation of themachine to carry or transport people or equipment
▪Operation of the machine outside of the plant specifications
▪Operation of the machine contrary to warning notices attached to the
machine and contained in the operator's manual.
This machine was designed and built according to the latest global safety
standards. In order to eliminate dangers as much as possible, it was technically
designed with great care and contains protective side plates and warning labels
for an increased safety of the operator. Additional risks may exist despite these
protective measures. These are designated as residual risks. Possible residual
risks with this machine:
▪Heat, noise, exhaust and carbon monoxide from the engine
▪Risk of fire due to incorrect refueling procedure
▪Gasoline or gasoline vapors
▪Electric shock and arc discharge
▪Injury due toincorrect hoisting technology
For your own protection and the protection of other people, make sure that the
safety instructions in this manual have been closely read and understood before
starting the machine.

3 Safety Regulations
3.3 Operational safety
DANGER
Carbon monoxide.
The application of a generator in buildings can LEAD TO DEATH WITHIN
MINUTES.
The exhaust fumes from the generator contain carbon monoxide (CO). This is an
invisible odorless poison. If the exhaust fumes of the generator can be smelled,
CO is being inhaled. Even if no exhaust fumes can be smelled, CO could still be
being inhaled.
➢NEVER use the generator in buildings, garages, crawl spaces or other
partially enclosed areas. Carbon monoxide can build up to deadly levels in
these areas. A fan or open window does NOT provide sufficient fresh air.
➢ONLY use generators outdoors and far away from windows, doors and
aeration. These openings can draw in generator exhaust fumes.
➢CO can penetrate into ahome, even if ageneratoris used properly. ALWAYS
use a battery-powered or battery-backup CO alarm in the home.
➢IMMEDIATELY get to fresh air if you feel unwell, dizzy or weak after using
the generator. Consult a physician. It could be carbon monoxide poisoning.
WARNING
Electric shock or risk of fire or explosion. Incorrect connection of the generator to
a building's mains supply can lead to current being lead from the generator back
into the power supply system. This can cause electric shock, serious injury or death
of the worker in the public utility company!
➢The following connectionprerequisites areto be met.
WARNING
Battery electrolyte is poisonous and dangerous, causing severe burns, etc.
contains sulfuric (sulphuric) acid.
Avoid contact with skin, eyes or clothing.

3 Safety Regulations
12
Connection prerequisites
The following prerequisites are to bemet to connect the generator tothe building's
mains supply.
▪The generator must meet the prerequisites with regard to performance,
voltage and frequency of the equipment.
▪The generator must be disconnected from the electric power supply.
▪Connections from the generator to the power supply system of a building
must be established by a licensed electrician.
▪The electrical connections must meet all laws and electrical regulations.
WARNING
Prerequisites for safe operationare familiarity with themachineand proper training.
Machines that are incorrectly operated or that are operated by untrained personnel
may pose a danger. Read through the operating instructions in this manual and in
the engine manual to make yourself familiar with the job and the proper use of the
operator's controls. Inexperienced operators must be instructed by personnel who
are familiar with the machine before they are allowed to operate the machine.
3.4 Operator qualifications
Only trained personnel may start, operate and switch off the machine. The
personnel must also have the following qualifications:

13
3 Safety Regulations
▪NEVER overload generator. The total amperage of the parts connected to
the generator may not exceed the output limit.
▪NEVER operate the machine in snow, rain or standing water.
▪NEVER allow untrained personnel to operate or maintain the generator.
Familiarize yourself with the operation and shutdown before starting the
generator.

a clean dry place and keep it out of reach of children.
▪ALWAYS make sure that the machine is stable and cannot tip, roll, slide or
fall during operation.
▪ALWAYS transport the generator in an horizontal position.
▪ALWAYS keep at least one meter distance from facilities, buildings or other
machines while operating the machine.
▪ALWAYS keep the area immediately around and under the machine clean,
tidy and free of grime and flammable materials. Check that there is also no
grime above the machine that could fall onto or into the machine or the
exhaust area.
▪ALWAYS keep all tools, power cables and other loose objects away from the
generator before starting.
▪Do NOT ground this generator.
▪If more than one electric device is connected to the generator, the additional
connected electric equipment must be connected to the generator via an
isolating transformer or a suitable FI switch (PRCD), whereby each additional
electric device must be operated via a separate isolating transformer or
PRCD.
Generator vibration
Generators vibrate during normal operation. Check during and after use of the
generator whether the generator or the extension cord and power cable show
damage due to vibration.
▪Repair any damage as needed or replace the parts affected.
▪Do not use any plugs or cables that showsigns of damage, such as damaged
or cracked insulation or blades.
