SAFETY LABEL LOCATIONS
These labels warn you of potential hazards that can cause seri-
ous injury. Read them carefully. If a label comes off or becomes
hard to read, contact your DEK generator dealer for a replace-
ment.
SAFETY INFORMATION
DEK generators are designed to give safe and dependable ser-
vice if operated according to instructions. Read and understand
this owner’s manual before operating your generator.
OPERATOR RESPONSIBILITY
Know how to stop the generator quickly in case of emergency.
Understand the use of all generator controls, output receptacles,
and connections. Be sure that anyone who operates the genera-
tor receives proper instruction. Do not let children operate the
generator.
Fire and Burn Hazards
The exhaust system gets hot enough to ignite some materials.
 Keep the generator at least 3 feet (1 meter) away from
buildings and other equipment during operation.
 Do not enclose the generator in any structure.
 Do not smoke when refueling.
 Keep flammable materials away from the generator.
 The muffler becomes very hot during operation and remains
hot for a while after stopping the engine. Be careful not to
touch the muffler while it is hot.
 Let the engine cool before storing the generator indoors.
 Refuel in a well ventilated area with the engine stopped.
 Fuel vapors are extremely flammable and may ignite after
the engine has started. Make sure that any spilled fuel has
been wiped up before starting the generator.
EMISSION CONTROL SYSTEM INFORMATION
The U.S. and California Clean Air Acts
EPA and California regulations require all manufacturers to fur-
nish written instructions describing the operation and mainte-
nance of emission control systems. The following instructions
and procedures must be followed in order to keep the emissions
from your DEK engine within the emission standards. Mainte-
nance, replacement, or repair of the emission control devices
and systems may be performed by any engine repair establish-
ment or individual, using parts that are ‘‘certified’’ to EPA stan-
dards.
DANGER
Connections to a Building Electrical System
Connections for standby power to a building electrical system
must be made by a qualified electrician. The connection must
isolate the generator power from utility power, and must comply
with all applicable laws and electrical codes. A transfer switch,
which isolates generator power from utility power, is available
through any of GXi’s authorized dealers of DEK generators.
Generator must be installed by a qualified electrician and
connected to transfer equipment as a separately derived sys-
tem in accordance with the National Electrical Code, NFPA
70. The generator shall be connected through transfer equip-
ment that switches all conductors other than the equipment
grounding conductor. The frame of the generator shall be
connected to an approved grounding electrode.
Improper connections to a building electrical system can
allow electrical current from the generator to backfeed into
the utility lines. Such backfeed may electrocute utility com-
pany workers or others who contact the lines during a power
outage, and the generator may explode, burn, or cause fires
when utility power is restored.
Ground System
DEK portable generators have a system ground that connects
generator frame components to the ground terminals in the AC
output receptacles. The system ground is not connected to the
AC neutral wire. If the generator is tested by a receptacle tester, it
will not show the same ground circuit condition as for a home
receptacle where the ground and neutral are connected.
Special Requirements
There may be Federal or State Occupational Safety and Health
Administration (OSHA) regulations, local codes, or ordinances
that apply to the intended use of the generator. Please consult a
qualified electrician, electrical inspector, or the local agency hav-
ing jurisdiction.
CARBON MONOXIDE GAS
Exhaust contains poisonous carbon monoxide, a colorless
and odorless gas. Breathing exhaust can cause loss of con-
sciousness and may lead to death. To keep exhaust gas
from accumulating, use in an area with adequate ventila-
tion. DO NOT use this generator in a garage, basement,
crawlspace, enclosed shed, or any other area that does not
have adequate ventilation. DO NOT use this generator near
ventilation ducts or open windows that may allow exhaust
gasses to enter your home or business. ONLY operate this
generator outdoors.
Electrocution Hazard
 Keep the generator dry.
 DO NOT use the generator in wet conditions, rain or
snow, or near a pool or sprinkler system
 DO NOT use when your hands are wet
NEVER START OR STOP THE ENGINE WITH DEVICES CON-
NECTED TO THE GENERATOR.
