Type
This engine/equipment requires regular unleaded gasoline.
• Use only fresh (no older than three months old), clean gasoline.
• Use a fuel stabilizer per the fuel stabilizer manufacturer’s
instructions.
Use of oxygenated fuels
Some conventional gasolines are blended with alcohol. These
gasolines are collectively referred to as oxygenated fuels. If you use
an oxygenated fuel, be sure it is unleaded and meets the minimum
octane rating requirement.
Before using an oxygenated fuel, confirm the fuel's contents. Some
states / Provinces require this information to be posted on the fuel
pump.
The following are Wacker Neuson approved percentages of
oxygenates:
ETHANOL - (ethyl or grain alcohol) 10% by volume. You may use
gasoline containing up to 10% ethanol by volume (commonly referred
to as E10). Gasoline containing more than 10% ethanol (such as E15,
E20, or E85) may not be used because it could damage the engine.
If you notice any undesirable operating symptoms, try another service
station, or switch to another brand of gasoline.
Fuel system damage or performance problems resulting from the use
of an oxygenated fuel containing more than the percentages of
oxygenates mentioned above are not covered under warranty.
Using gasoline / ethanol blends
This portable generator is not for use with gasoline / ethanol blends

4.3 Determining Power Requirements
This generator is designed to operate single-phase, 60 Hz appliances
running at 120 VAC or 240 VAC. Check the nameplate or label
provided on tools and appliances to make sure their power
requirements match the power output of the generator.
Some appliances and tools require a surge of current when starting.
This means that the amount of power needed to initially start the
equipment is larger than the power required to keep it running. The
generator must be capable of supplying this “surge” current. Other
types of appliances require more power than is actually stated on their
nameplate.
The information in “Approximate Starting Power Requirements” is
offered only as a general guideline to help you in determining power
requirements for different types of equipment. Check with your nearest
Wacker Neuson dealer, or contact the manufacturer or dealer of the
tool or appliance, with questions regarding its power requirements.
NOTICE: If a tool or appliance does not reach full speed within a few
seconds when switched on, turn it off immediately to avoid damage.
Approximate Starting Power Requirements
• Incandescent lights and appliances such as irons and hot plates, which
use a resistive-type heating element, require the same wattage to start
and run as is stated on their nameplates.
• Fluorescent and mercury lamps require 1.2–2 times their stated
wattage to start.
• Electrical motors and many types of electrical tools often require a
large starting current. The amount of starting current depends on the
type of motor and its use.
• Most electrical tools require 1.2–3 times their stated wattage for
starting.
• Loads such as submersible pumps and air compressors require a very
large force to start. They need as much as 3–5 times the wattage
stated on the nameplate in order to start.
If the wattage is not given for a particular tool or appliance, it can be
calculated by multiplying its voltage and amperage requirements:
Single Phase: VOLTS x AMPS = WATTS

4.4 Installation
Place the generator in an area where it will not be exposed to rain,
snow, or direct sunlight. Make sure it is positioned on firm, level
ground, so it will not slide or shift. Position the engine exhaust away
from areas where people may be present.
The surrounding area must be free from water and moisture. All
components must be protected from excessive moisture.
4.5 Installing the Spark Arrester
A spark arrester is available as an accessory for this machine. Install
the spark arrester prior to using the machine in areas where spark
arresters are required.
To install the spark arrester:
4.5.1 Position the spark arrester (a) on the engine exhaust pipe (b).
4.5.2 Secure the spark arrester with the screw (c) included with the spark
arrester.

Operation GV 3800A
4.6 Generator Derating
All generators are subject to derating for altitude and temperature.
Internal combustion engines, unless modified, run less efficiently at
higher altitudes due to the reduction of air pressure. This translates
into a lack of power and thus reduction in generator output.
Temperature affects both engine and generator performance. As
temperature increases, an engine will run less efficiently and more
resistance will be found in electrical components. Therefore, as the
temperature increases, the output of the generator decreases. Altitude
also affects the cooling capacity of air—the higher the altitude the less
dense the air is and thus the lower its ability to transfer heat.
For every increase in altitude of 500 m (1650 ft.) above 1000 m (3300
ft.), the output of the generator will be reduced by 3%. For every
increase of 5° C (9° F) in ambient temperature above 40° C (104° F),
the output of the generator will be reduced by 3%. Use the tables
shown for altitude and temperature deration factors. It may be
necessary to consider both altitude and ambient temperature deration
factors to determine true generator output.

4.7 Grounding the Generator
Location
A ground connection (a) is located on the generator frame.
a
Function
This ground connection is used for electrically grounding the
generator when necessary to comply with the National Electrical
Code and other federal, state, and local regulations. For grounding
requirements in your area, consult with a qualified electrician,
electrical inspector, or local agency having jurisdiction over electrical
compliance.
• If the generator is used at a construction site, there may be
additional regulations which must be observed.
• In some areas, generators are required to be registered with local
utility companies.
• There is a conductor between the generator (stator neutral
winding) and the frame.
4.8 Operating Heavy Loads
Limit operations requiring the maximum rated output of 3800 Watts to
20–30 minutes. For continuous operation, do not exceed the
continuous rated output of 3400 Watts.
NOTICE: DO NOT exceed the current limit specified on the control
panel for any receptacle.

Operation GV 3800A
4.9 Use of Extension Cords
When a long extension cord is used to connect an appliance or tool to
the generator, a voltage loss occurs—the longer the cord, the greater
the voltage loss. This results in less voltage being supplied to the
appliance or tool and increases the amount of current draw or reduces
performance. A heavier cord with a larger wire size will reduce the
voltage loss.
Damaged extension cords can cause electrical shock, resulting in
serious injury or death. DO NOT use worn, bare, or frayed cords.

4.13 Voltage Selector Switch
The voltage selector switch (e) switches the generator output between
the single-voltage mode (120V) and the dual-voltage (120/240V)
mode.
In single-voltage mode, the full rated power of the generator is shared
between the two 120V duplex receptacles.
In dual-voltage mode, generator power is shared between the 120/
240V twist-lock receptacle and the 120V duplex receptacles. To
achieve full power, use only the 120/240V twist-lock receptacle. Note:
Only use the 120/240V twist-lock receptacle (j) when the VSS is in the
120V/240V position.
NOTICE: NEVER change the position of the voltage selector switch

8 Emission Control Systems Information and Warranty
The Emission Control Warranty and associated information is valid only for the
U.S.A., its territories, and Canada.
8.1 Emission Control System Background Information
Introduction
Wacker Neuson spark-ignited engines/equipment must conform with applicable
Environmental Protection Agency (EPA) and the State of California emissions
regulations. There are two types of emissions that fall under these regulations: 1)
exhaust, and 2) evaporative. These regulations require that manufacturers warrant
the emission control systems for defects in materials and workmanship.
Furthermore, EPA and California regulations require all manufacturers to furnish
written instructions describing how to operate and maintain the engines/equipment
including the emission control systems. This information is provided with all
Wacker Neuson engines/equipment at the time of purchase.
Exhaust Emissions
The combustion process produces carbon monoxide, oxides of nitrogen, and
hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very important
because, under certain conditions, they react to form photochemical smog when
subjected to sunlight. Carbon monoxide does not react in the same way, but it is
toxic.
Wacker Neuson utilizes lean carburetor settings and other systems to reduce the
emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.
Evaporative Emissions
Evaporative emissions are fuel emissions and generally include emissions that
result from permeation of fuel through the fuel-system materials or from ventilation
of the fuel system.
Wacker Neuson utilizes low-permeation fuel lines and fuel tanks where applicable
to reduce evaporative emissions.
Problems that may affect Emissions
If any of the following symptoms arise, have the engine/equipment inspected and
repaired by a Wacker Neuson dealer/service center.
Hard starting or stalling after starting
Rough idling
Misfiring or backfiring under load
Afterburning (backfiring)
Presence of black exhaust smoke during operation
High fuel consumption

warranty repairs must be performed by an authorized Wacker Neuson dealer/
service center.
The engine/equipment must be presented to an authorized Wacker Neuson dealer/
service center as soon as a problem exists. Contact Wacker Neuson Product
Support Department (1-800-770-0957) or visit wackerneuson.com to find a dealer/
service center in your area, or to answer questions regarding warranty rights and
responsibilities.
How to Make a Claim
In the event that any emission-related part is found to be defective during the
warranty period, you shall notify Wacker Neuson Product Support Department (1800-770-0957), and you will be advised of the appropriate dealer/service center
where warranty repair can be performed. All repairs qualifying under this limited
warranty must be performed by an authorized Wacker Neuson dealer/service
center.
You must take your Wacker Neuson engine/equipment along with proof of original
purchase date, at your expense, to the authorized Wacker Neuson dealer/service
center during their normal business hours.
For owners located more than 100 miles from an authorized dealer/service center
(excluding the states with high-altitude areas as identified in 40 CFR Part 1068,
Appendix III), Wacker Neuson will pay for pre-approved shipping costs to and from
an authorized Wacker Neuson dealer/service center.
Claims for repair or adjustment found to be caused solely by defects in material or
workmanship will not be denied because the engine/equipment was not properly
maintained and used.
The warranty repairs should be completed in a reasonable amount of time, not to
exceed 30 days.

8.4 California Evaporative Emission Control Warranty Statement
Your Warranty Rights and Obligations
The California Air Resources Board and Wacker Neuson Corporation, Inc., are
pleased to explain the evaporative emission control system (EECS) warranty on
your model year 2008 and later portable generator. In California, new portable
generators must be designed, built and equipped to meet the State’s stringent antismog standards. Wacker Neuson Corporation must warrant the EECS on your
portable generator for the period of time listed below, provided there has been no
abuse, neglect or improper maintenance of your portable generator.
Your EECS on your model year 2008 and later portable generator includes the fuel
and vent line, fuel and vent line clamps, fuel and vent line fittings, carbon canister,
fuel tank and fuel tank cap, purge port connector, gaskets, and mounting brackets.
Where a warrantable condition exists, Wacker Neuson Corporation will repair your
portable generator at no cost to you including diagnosis, parts and labor.
Manufacturer’s Warranty Coverage
This EECS is warranted for two years from the initial date of purchase. If any
evaporative emission-related part on your equipment is defective, the part will be
repaired or replaced by Wacker Neuson Corporation at no charge to you. The
owner shall not be charged for diagnostic labor that leads to determination that a
warranted part is in fact defective, provided that such diagnostic work is performed
at a Wacker Neuson Corporation authorized service center.
Warranty Period
Any warranted part that is not scheduled for replacement as required maintenance,
or which is scheduled only for regular inspection to the effect of “repair or replace
as necessary”, shall be warranted for two years. Any warranted part that is
scheduled for replacement as required maintenance shall be warranted for a time
not less than the remaining warranty period.
Owner’s Warranty Responsibilities
As the portable generator owner, you are responsible for performance of the
required maintenance listed in your Operator’s Manual. Wacker Neuson
Corporation recommends that you retain all receipts covering maintenance on your
portable generator, but Wacker Neuson Corporation cannot deny warranty solely
for the lack of receipts.
As the portable generator owner, you should however be aware that Wacker
Neuson Corporation may deny you warranty coverage if your portable generator or
a part has failed due to abuse, neglect, or improper maintenance or unapproved
modifications.
You are responsible for presenting your portable generator to Wacker Neuson
Corporation’s authorized service center as soon as the problem exists. The
warranty repairs should be completed in a reasonable amount of time, not to
exceed 30 days. If you have a question regarding your warranty coverage, you
should contact your nearest authorized Wacker Neuson service center or call 1800-770-0957.

What is not Covered
All failures caused by abuse, neglect, or improper maintenance are not covered. In
addition, the use of add-on or modified parts will be grounds for disallowing a
warranty claim.
What is covered

coverage may be excluded from such warranty coverage if Wacker Neuson
Corporation demonstrates that the portable generator has been abused,
neglected, or improperly maintained, and that such abuse, neglect, or improper
maintenance was the direct cause of the need for repair or replacement of the part.
That notwithstanding, any adjustment of a component that has a factory installed,
