Transport, packaging, storage
5.1 Packaging
All used packaging materials and packaging aids are re-
cyclable and should be taken to a materials recycling de-
pot to be disposed of.
The delivery packaging is made of cardboard, so please
dispose carefully by having it chopped up and given to
the recycling collection.
The film is made of polyethylene (PE) and the cushioned
parts of polystyrene (PS). These materials should be
taken to a collection point for recyclable materials or to
the local waste disposal company.
5.2 Storage
Store the generator thoroughly cleaned in a dry, clean
and frost-free environment. Generators must not be
stacked on top of each other. Also no other objects may
be placed on them.
If the generator is not used for more than 30 days, it is re-
commended to empty the fuel tank completely. For petrol
motors, it is important to empty the carburetor pan: older
petrol residues will damage the parts that come into con-
tact with them.
Short-term storage (less than 1 year) PG-I 42 SE
Petrol in the fuel tank has a maximum lifetime of up to 1
year if proper fuel stabilizers are added and stored in a
cool, dry place. The petrol in the carburetor can be sedi-
ment and block the carburetor if it is not used or drained
within 2 weeks.
Procedure
1. Ensure that all devices are disconnected from the ge-
nerator.
2. Add a proper fuel stabilizer to the tank.
3. Run the generator for 10 minutes to allow the treated
fuel to pass through the fuel system and carburetor.
4. While the generator is running, turn the fuel valve to
the "OFF" position and keep the generator running
until the engine shuts down due to fuel shortage. This
normally takes a few minutes.
5. Set the motor switch to "OFF".
6. Allow the generator to cool down completely before
proceeding.
7. Optional: To ensure that the fuel is drained comple-
tely from the carburetor, use the drain screw on the
carburetor to drain excess fuel into a suitable contai-
ner.
8. Remove the spark plug connector and spark plug and
pour a tablespoon of oil into the cylinder.
9. Slowly pull the cable to move the piston in the cylinder
to distribute the oil and lubricate the cylinder.
10. Replace the spark plug and spark plug connector.
11. If the power generator contains a battery, disconnect
and charge it as described in the instructions.
12. Clean the generator according to generator main-
tenance.
13. Store the generator in a cool, dry place away from di-
rect sunlight.
Long term storage (over 1 year) PG-I 42 SE
When storing for more than 1 year, the fuel tank and the
carburetor must be completely empty.
Procedure
As for short-term storage, additionally applies:
the fuel must be completely drained from the fuel tank
and the carburetor. Drain the petrol into a suitable conta-
iner.
ATTENTION!
The generator should be started every seven days at
the latest and run for approx. 30 minutes. If this is not
possible and the generator is out of service for more
than 30 days, appropriate measures should be taken
to ensure proper storage.
ATTENTION!
It is important to prevent deposits in the fuel system
(carburettor, fuel hose or tank) during storage. Alco-
hol-containing fuels (ethanol or methanol) can
absorb moisture which leads to acid formation during
storage. Acidic gases can damage the fuel system
and should be drained for 30 days or more prior to
storage. Never use engine or carburetor cleaner in
the fuel tank as this could cause permanent damage.
ATTENTION!
Fire or explosion can cause severe burns or death.
Fill or drain fuel only in well-ventilated outdoor
spaces. Do not pump fuel directly into the generator.
Use an approved container to transport fuel to the
generator. Never use a fuel tank, hose, cylinder or
other fuel-related object that is damaged or appears
to be damaged. Do not overfill the fuel tank. Keep
fuel away from sparks, open fire, ignitions, heat and
other ignition sources. Do not light or smoke cigaret-
tes.
ATTENTION!
Petrol is highly flammable and explosive under cer-
tain conditions. Do not smoke or produce sparks in
the immediate environs.

Transport, packaging, storage
PG-I SE Series | Version 1.04 9
Storage of the generator PG-I 80 SE
Allow the generator to cool for 30 minutes before prepa-
ring the generator for storage. Follow the instructions
below.
Between 2 months and up to one year
Drain the fuel from the tank and dispose of it in a suitable
container in accordance with legal and local regulations.
One year or longer
- Remove spark plug.
- Drain the fuel from the tank and dispose of it in a
suitable container in accordance with national and
local regulations.
- Fill a tablespoon of motor oil into the reserve cylin-
der. Start the engine slowly with the tow rope to dis-
tribute the engine oil.
- Replace the spark plug.
- Change the motor oil and fill with fresh petrol after
removal from storage.
To prevent accidental or unintended ignition of your ge-
nerator during storage, the following precautions should
be followed:
- When storing the generator, make sure that the mo-
tor switch and fuel valve are set to "OFF".
- If your power generator contains a battery, dis-
connect it from the power generator.
After storing the generator
If the generator has been stored improperly with gasoline in
the fuel tank and/or carburetor for an extended period of
time, all fuel must be drained and the carburetor thoroughly
cleaned. This process involves technically advanced tasks.
Please call our technical support for assistance. If the fuel
tank and carburetor were completely empty before storing
the generator, follow the steps below when removing the ge-
nerator from storage.
1. Fill the generator with fuel according to the
instructions.
2. When the motor switch is set to "OFF", set the fuel tap
to "ON". After 5 minutes, check the carburettor and air
filter area for leaking fuel. If this is detected, the carbu-
retor must be disassembled and cleaned or replaced.
If no fuel leaks are detected, set the fuel tap to "OFF".
3. Check oil level and top up with clean, fresh oil if neces-
sary.
4. Check the air filter and clean it of obstacles such as
beetles or cobwebs. If necessary, clean as described
in the air filter section.
5. If the generator contains a battery, connect it accor-
ding to the battery connection procedure.
6. Start the generator.
Important temperature information
Your power generator PG-I 42 SE is designed for conti-
nuous operation at ambient temperatures from -15 °C to
50 °C.
Your power generator PG-I 80 SE is designed for conti-
nuous operation at ambient temperatures from -10 °C up
to 45 °C.
If the generator is exposed to temperatures outside this
range during storage, it should be brought back into this
temperature range before operation. In any case, the ge-
nerator must always be operated outdoors, in a well-ven-
tilated area and away from doors, windows and other
ventilation openings.
NOTE!
If you store the petrol in a suitable container for later
use, make sure that the petrol has been treated with fuel
in accordance with the instructions of the stabiliser ma-
nufacturer.
NOTE!
The motor work well with 10% or less ethanol blends.
When using fuel blends there are some points to con-
sider:
- Ethanol-petrol blends can absorb more water than
petrol alone.
- These blends can eventually separate and leave
water or watery dirt in the tank, fuel valve and car-
buretor.
- With gravity-fed fuel supplies, this compromised
fuel can be sucked into the carburetor and damage
the engine and/or cause potential hazards.
- There are few suppliers of fuel stabilizers designed
for use with ethanol blended fuels.
- Damage or hazards caused by the use of incorrect
fuel, incorrectly stored fuel and/or incorrectly formu-
lated stabilizers are not covered by the manufactu-
rer's warranty.

The ECO button controls the engine speed and saves
fuel. When the switch is in the ON (I) position and no
equipment is connected to the appliance, the engine
runs at idle. When a device is added, the engine speed
increases to power the item. When the unit is removed,
the engine returns to idle.
Fuel tank
Before operation, start with a full tank to increase the
operating time. Always refuel with the engine switched
off and cooled down.
Fuel gauge
The fuel gauge is a mechanical device that measures the
fuel level in the tank. The red indicator in the window in-
dicates the fuel level in relation to full or empty.
Ground terminal
The ground terminal is used to assist in properly groun-
ding the generator to help protect against electrical
shock. Consult with a local electrician for grounding re-
quirements in your area.
LED display
LEDs indicate when the generator is running, overloaded
or in need of lubricant.
Oil indicator light (red):
As the motor oil level drops below the required minimum
level, this light switches on and the motor stops automa-
tically. The engine cannot be restarted until oil has been
refilled and the correct level has been reached.
Motor ON/OFF switch
In to start the generator, the switch must be set to "I". If
the switch is set to "O", the motor is stopped and cannot
be started.
Parallel connector between 2 generators
The parallel connection of two generators enables a cor-
respondingly increased power consumption of the
connected loads.
Wire rope hoist
Used when the battery voltage is too low to start the star-
ter motor. Pull the wire rope to start the generator engine
manually.
12V output
The 12V output is used to charge batteries. To charge
batteries, please follow the battery manufacturer's in-
structions.
Multi-Switch
The multi-switch is used to control fuel and choke. When
storing the generator, the multiswitch must be switched
to the OFF position.
Petrol cock
The fuel cock controls the flow of fuel from the tank to the
carburetor. The valve knob must be set to "I" to start and
operate the generator. Set the fuel tap to "O" when the
engine is switched off and the generator is stored or
transported.
NOTE!
If high electrical loads are connected simultaneously,
turn off the ECO switch to reduce voltage changes.
NOTE!
The overload indicator may also turn on for a few
seconds when electrical loads requiring a high star-
ting current have been connected, e.g. Compressors,
pumps or refrigeration units. In this case, there is no
interference.
NOTE!
If the oil light flashes during starting and the engine
does not start, oil must be refilled before a new start
attempt.
Only operate the generator on flat surfaces! An une-
ven position of the generator can lead to activation of
the engine oil protectio

DANGER!
Check the oil frequently during the running-in period.
Refer to the Maintenance section for recommended
service intervals.
DANGER!
We consider the first 5 operating hours as the run-
ning-in period for the unit. During the running-in
period, stay at or below 50% of the rated power and
occasionally vary the load to allow the stator win-
dings to heat up and cool down. Adjusting the load
also changes the motor speed and helps to break in
the piston rings. Change the oil after the 5 hour run-
ning-in period.
NOTE!
The engine is equipped with a low oil cut-off and stops
when the oil level in the crankcase falls below the
threshold value.
NOTE!
Synthetic oil can be used after the first running-in
period of 5 hours. The use of synthetic oil does not
extend the recommended oil change interval.
NOTE!
Gasoline and its vapors are highly flammable and
explosive. Handle gasoline with care to avoid serious
injury and damage to property. Keep away from igni-
tion sources, handle only outdoors, do not smoke
when refilling fuel and immediately wipe up spilled
material.
DANGER!
DO NOT mix oil with fuel.

Start-Up
PG-I SE Series | Version 1.04 15
Using the fuel stabilizer:
Fuel becomes old, oxidizes and decomposes over time.
Adding a fuel stabilizer (not included) will extend fuel life
and prevent the formation of deposits that can clog the
fuel system. Follow the fuel stabilizer manufacturer's in-
structions to obtain the correct stabilizer to fuel ratio.
Step 1: Mix the fuel stabilizer and gasoline before filling
the tank. Use a gasoline can or other approved
fuel container and shake gently to combine.
Step 2: Replace the fuel cap and secure it.
Step 3: Run the engine for at least 5 minutes to allow the
stabilizer to distribute itself throughout the fuel
system.
Damage to the fuel system or performance problems
caused by the use of an oxygenated fuel containing
more than the percentage of oxygenates listed below is
not covered under warranty.
Ethanol:
Gasoline containing up to 10% ethanol by volume (com-
monly referred to as E10) is acceptable. E15 and E85
are not.
8.2 Power generation capacity
If possible, do not operate the power generator without
consumers.
However, no consumers should be connected when
starting.
The consumers may only be connected one after the
other after starting the generator.
Step 1: Start the motor without consumers connected.
Step 2: Connect the first consumer and switch it on.
Connect the largest consumer first.
Step 3: Wait until the power generator has stabilized (the
motor runs smoothly and the connected device
works properly).
Step 4: Connect the next consumer and switch it on.
Step 5: Wait for the generator to stabilize.
Step 6: Repeat steps 4 and 5 for each additional con-
sumer.

and switch them on.
Power
Calculation of the power in watts required for starting and
operating the loads to be supplied.
Step 1: After starting, allow the engine to stabilize and
warm up for a few minutes.
Step 2: Calculate the total power of these consumers in
watts. This value corresponds to the power re-
quired to keep the loads running.
Watt = Volt x Ampere
Step 3: Consider the starting currents of the consumers.
Step 4: Plug in the desired single-phase 230 Volt 50 Hz
AC consumers and switch them on.
The connection of a power generator to the power lines
of your power supply company or to another power
source must be clarified in advance with the network
operator.
NOTE!
If the generator is used at high altitude or at high
temperatures, the air/fuel mixture ratio may be
excessively high, resulting in higher consumption
and lower performance. Check the actual power of
the generator using the following correction factors:
TEMPERATURE: the power decreases on average
by 2% per 5 degrees Celsius at temperatures above
20 degrees Celsius.
ALTITUDE: the power decreases on average by 1%
per 100 m above sea level. If the altitude for opera-
tion exceeds 2000 m above sea level, the engine
manufacturer's after-sales service should be consul-
ted for any fuel mixture adjustments..
ATTENTION!
If the motor does not start after 3 starting attempts or
stops during operation, check that the generator is
horizontal and that sufficient motor oil is filled.
NOTE!
The ec switch should be set to OFF for heavy electri-
cal loads or momentary fluctuations.
NOTE!
- DO NOT connect 3-phase consumers to the po-
wer generator.
- DO NOT overload the generator.
ATTENTION!
Ensure that the rated voltage and frequency of the
generator are compatible with all electrical loads that
the equipment must supply. If the current consump-
tion exceeds the generator power, one or more loads
must be disconnected and connected to a separate
