2.1 Overview
Generator 
application
This generator is an exceptionally quiet and compact machine designed to provide 
single phase power for construction, commercial, and residential applications. 
State-of-the-art inverter technology ensures a consistent flow of clean and stable 
power suitable for operating not only tools, but also delicate electronic equipment.
Safety notices
 Do not exceed the power output of the generator. Damage to tools or generator 
can occur. Refer to Technical Data.
 When using the generator as a stand-by or substitute power supply, make sure 
the voltage and phase rotation of the line connections match those of the main 
lines. Failure to match phase rotation and voltage may cause equipment 
connected to the generator to operate incorrectly! This could create unsafe 
operating conditions.
 Do not exceed the rated current limit of any receptacle.
2.2 Preparing the Machine for First Use
Preparing for 
first use
To prepare your machine for first use:
1. Make sure all loose packaging materials have been removed from the machine.
2. Check the machine and its components for damage. If there is visible damage, 
do not operate the machine! Contact your Wacker Neuson dealer immediately 
for assistance.
3. Take inventory of all items included with the machine and verify that all loose 
components and fasteners are accounted for.
4. Attach component parts not already attached.
5. Add fluids as needed and applicable, including fuel, engine oil, and battery acid.
6. Move the machine to its operating location.
DANGER
Carbon monoxide. Using a generator indoors CAN KILL YOU IN MINUTES. 
Generator exhaust contains carbon monoxide (CO). This is a poison you cannot 
see or smell. If you can smell the generator exhaust, you are breathing CO. But 
even if you cannot smell the exhaust, you could be breathing CO.
f NEVER use a generator inside homes, garages, crawlspaces, or other partly 
enclosed areas. Deadly levels of carbon monoxide can build up in these areas. 
Using a fan or opening windows and doors does NOT supply enough fresh air.
f ONLY use a generator outside and far away from windows, doors, and vents. 
These openings can pull in generator exhaust.
f Even when you use a generator correctly, CO may leak into the home. ALWAYS 
use a battery-powered or battery-backup CO alarm in the home.
f If you start to feel sick, dizzy, or weak after the generator has been running, 
move to fresh air RIGHT AWAY. See a doctor. You could have carbon monoxide 
poison.
