9.10 Charging external devices (Fig. 3)
m DANGER!
Danger due to incorrect charging.
1. Plug the adapter cable with 12 V terminals (19) into 
the 12 V DC connection (14) provided for this.
2. If the 12 V DC safety release (15) has been tripped, 
the  12  V  DC  safety  release  (15)  can  restore  the 
output power of the inverter power generator. 
Press and hold the 12 V DC safety release button 
(15) for 1 second.
3. If  the  12  V  DC  safety  release  (15)  has  not  been 
triggered,  the  12  V  DC  safety  release  (15)  is  in-
eective.
10. Cleaning and maintenance
Before carrying out any cleaning or maintenance work, 
switch o the engine and remove the spark plug con-
nector (24) from the spark plug (23).
ATTENTION! Danger of burning! Wait until the de-
vice has cooled down before performing cleaning or 
maintenance work.
10.1 Cleaning
Keep protective devices, air vents and the motor hous-
ing as free of dust and dirt as possible. Rub the device 
clean with a clean cloth or blow it o with compressed 
air at  low pressure. We recommend that you clean the 
device directly after every use.
Clean the device at regular intervals using a damp 
cloth and a little soft soap. Do  not  use  any  cleaning 
products or solvents; they could attack the plastic parts 
of the device. Make sure that no water can penetrate 
the device interior.
10.2 Maintenance
WARNING!
Always  wear  protective  gloves  and  a  mask  during 
maintenance work!
10.2.1 Checking the oil level
1. Proceed as described in 8.2.
10.2.2 Changing oil (Fig. 7 + 8)
Change the engine oil after 20 operating hours, then 
after 50 hours or every three months.
The engine oil change should be carried out while the 
engine is at operating temperature.
9.5 “RESET” button (12) (Fig. 3)
If the overload protection has been triggered and the 
overload indicator (7) lights up red, the “RESET” button 
(12) can restore the output power of the power gen-
erator/inverter. It  is  then  not  necessary  to  restart  the 
engine.
1. Press and hold the “RESET” button (12) for 1 sec-
ond until the light (red) is extinguished and the op-
eration indicator (6) (green) illuminates.
If the overload protection has not tripped, the “RESET” 
button (12) has no eect.
9.6 Oil warning indicator (8) (Fig. 3)
The indicator activates when the oil level is too low and 
deactivates as soon as the oil level is sucient.
9.7 Automatic oil cut-o
The automatic oil cuto system responds when there 
is too little engine oil. The oil warning indicator (8) 
starts Àashing when there is too little oil in the engine. 
The indicator lamp starts to light up when the oil quan-
tity  has  not  reached  the  safety  quantity.  The  engine 
switches itself  o after a  short time. It is not possible 
to  start  the  engine  until the  engine  oil  has been ¿lled 
(see chapter 8.2).
The indicator activates when the oil level is too low and 
deactivates as soon as the oil level is sucient.
If the oil level is too low, the oil warning indicator (8) 
lights up during the start attempt. Top up engine oil as 
described in 8.2 and repeat the starting procedure.
9.8 Energy saving switch (10) (Fig. 3)
To reduce the fuel consumption when idle, move the 
energy saving switch (10) to the “ON” position.
The  energy  saving  switch  (10)  must  be  switched  o 
when electrical devices that require a high starting cur-
rent are connected, for example a compressor. Even 
when the power generator is started, the energy saving 
switch must be initially set to “OFF”.
9.9 USB connection (9) (Fig. 3)
This power generator is equipped with two USB con-
nections. These can be used to charge smartphones 
for  ex am ple .
5. Visually inspect the spark plug (23). Remove any 
deposits present using a wire brush.
6. Check the spark plug gap. Set the electrode gap to 
0.6 to 0.7 mm with a feeler gauge.
7. The reassembly takes place in reverse order.
NOTE
A loose spark plug can overheat and cause damage 
to the engine. Tightening the spark plug too much can 
damage the thread in the cylinder head.
10.2.5 Clean the fuel ¿lter insert (Fig. 13 + 14)
Note: The fuel ¿lter insert  (25) is a  ¿lter cup which is 
located directly under the tank cover (2) and ¿lters all 
the fuel ¿lled in.
1. Set the on/o switch (11) to the “OFF” position.
2. Open the tank cover (2).
3. Remove the fuel  ¿lter  insert (25)  and the ¿ll  level 
marking  (26).  Clean it in a nonÀammable solvent 
or a solvent with a high Àash point.
4. Reinsert the fuel ¿lter insert (25) with the ¿ll level 
marking (26).
5. Close the tank cover (2).

10.2.3 Air ¿lter (Fig. 9 + 10)
NOTE!
Risk of damage!
Operating  the  engine  without  a  ¿lter  element  or  with 
a damaged ¿lter element can cause engine damage.
- Never run the engine without the air ¿lter element or 
with a damaged ¿lter element. This would allow dirt 
into the engine, which would result in severe dam-
age to the engine.
Clean  the  air  ¿lter  (22) every  50  operating  hours,  re-
place if necessary.
1. Remove the engine cover (3) (Fig. 7).
2. Remove the air ¿lter cover by pressing the fasten-
ing tabs on the side.
3. Remove the air ¿lter (22).
