For your convenience, DEK offers a complete range of generator
accessories. Please ask your local retailer for more details or call
[1] 919-550-3221.
Universal Generator Cover:
Heavy duty nylon cover
fits over most models of
4000W to 7500W generators. A flexible handle bar flap accommodates most common
handle bar designs. The
cover keeps water, ice,
snow, dust and dirt from
damaging your generator when it is in storage.
It can also be used as a
rain cover to protect the
generator when stored
outdoors. The cover
cannot be used while
the generator is in operation. The generator
should be allowed to cool down for approximately 15 minutes after
being shut down, prior to placing the cover over the generator.
Adapters:
Converts 240V twist lock (L14-30)
to six (6) 120V outlets. Lighted
ends show when power is on.
Ideal for use in combination with a
240V extension cord. Can handle
up to 30 Amps (7200 Watts).
Extension Cords:
240V, 10/4, heavy duty extension
cords with L14-30 connectors at
each end. Lighted end shows when
power is on. Ideal for use in com-
bination with the 240V to 120V
adapter, eliminating up to six
120V extension cords. This cord
reduces harmful voltage drops
experienced when using most
120V extension cords. Available
in 25’ lengths and can be combined
to reach the desired length.
SAE 10W30 Motor Oil:
A premium high performance
formulation designed for high
RPM small gasoline engines
such as those used on generators. This oil provides excellent
protection against viscosity and
thermal breakdown that often
happens under the prolonged
severe duty experienced by generator engines. Use of this oil
formulation is highly encouraged
by the manufacturer. Frequent
oil changes with high quality motor oil will prolong the life of your
DEK generator.
Fuel Stabilizer:
Use of DEK’s fuel stabilizer
keeps your gasoline fresh for up
to 12 months. Gasoline breaks
down in 60 days, potentially
causing damage to your engine.
DEK recommends storing your
generator with the fuel tank full
and with fuel stabilizer added.
This protects the engine and fuel
system from the effects of humidity and ensures your generator is
ready for use at all times.

WARNINGS
4550 Pro, 5650, 6500(EL), 7550 Pro
This owner’s manual is considered a permanent part of the generator and should remain with the generator if resold. The information and specifications included in this publication were in
effect at the time of approval for printing.
GXi Outdoor Power, LLC, exclusive marketer of DEK Heavy
Duty Power Equipment, reserves the right to discontinue or
change specifications or design at any time without notice and
without incurring any obligation whatever. No part of this publication may be reproduced without written permission.
EMISSION CONTROL SYSTEM INFORMATION
The U.S. and California Clean Air Acts
EPA and California regulations require all manufacturers to furnish written instructions describing the operation and maintenance 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. Maintenance, replacement, or repair of the emission control devices
and systems may be performed by any engine repair establishment or individual, using parts that are ‘‘certified’’ to EPA standards.
SAFETY LABEL LOCATIONS
These labels warn you of potential hazards that can cause serious injury. Read them carefully. If a label comes off or becomes
hard to read, contact your DEK generator dealer for a replacement.
SAFETY INFORMATION
DEK generators are designed to give safe and dependable service 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 generator receives proper instruction. Do not let children operate the
generator.
DANGER
CARBON MONOXIDE GAS
Exhaust contains poisonous carbon monoxide, a colorless
and odorless gas. Breathing exhaust can cause loss of consciousness and may lead to death. To keep exhaust gas
from accumulating, use in an area with adequate ventilation. 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.
DANGER
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 CONNECTED TO THE GENERATOR.
WARNING
The engine exhaust from this product contains chemicals
known to the State of California to cause cancer, birth defects or other reproductive harm.
DANGER
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.
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.
WARNING
Generator must be installed by a qualified electrician and
connected to transfer equipment as a separatel y derived system in accordance with the National Electrical Code, NFPA
70. The generator shall be connected through transfer equipment 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 company 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 having jurisdiction.

WARNINGS
4550 Pro, 5650, 6500(EL), 7550 Pro
AC Applications
Before connecting an appliance or power cord to the generator:
1. Make sure that appliances are in good working order.
Faulty appliances or power cords can create a potential for
electrical shock. If an appliance begins to operate abnormally, becomes sluggish or stops suddenly, turn it off immediately.
2. Disconnect the appliance, and determine whether the problem is the appliance, or if the rated load capacity of the generator has been exceeded.
3. Make sure that the electrical rating of the tool or appliance
does not exceed that of the generator. Never exceed the
maximum power rating of the generator. Power levels between rated and maximum may be used for no more than
30 minutes.
Substantial overloading will open the circuit breaker. Exceeding the time limit for maximum power operation or
slightly overloading the generator may not switch the
circuit breaker or circuit protector OFF, but will shorten the
service life of the generator.
Limit operation requiring maximum power to 30 minutes. For
continuous operation (longer than 30 minutes), do not exceed
80% of the rated power balanced equally on the A&B sides of
the Alternator.
The total power requirements (VA) of all appliances connected
must be considered. Appliance and power tool manufacturers
usually list rating information near the model number or serial
number.
WARNING
Failure to properly follow maintenance instructions and
precautions can cause serious injuries or death. Always
follow the inspection and maintenance recommendations
and schedules in this owner’s manual.
Safety Precautions:
Make sure the engine is off before you begin any maintenance
or repairs. This will eliminate several potential hazards:
Carbon monoxide poisoning from engine exhaust.
Be sure there is adequate ventilation whenever you
operate the engine.
Burns from hot parts.
Let the engine and exhaust system cool before touching.
Injury from moving parts.
In the State of California a spark arrestor is required by law.
Other states may have similar laws. Federal laws apply on all
federal lands. If you equip the muffler with a spark arrestor, it
must be maintained in effective working order. See page 11.
Rapid retraction of the recoil starter cord can pull the
starter cord back faster than you can let go. When starting
the engine, pull the cord slowly until resistance is felt then
pull rapidly to avoid kickback.
Do not run the engine unless instructed to do so.
DANGER
Changing the speed of the generator by adjusting the governor can cause damage to the generator, devices attached to the generator, and may result in bodily injury. Do not adjust or
tamper with the engine speed setting.
