GENERATOR  
FEATURES  
All models have a 120-volt ground fault  
circuit interrupter (GFCI) receptacle. The  
GFCI receptacle is on the control panel or top  
coverofalternator(MGR2900A). The GFCI  
protects you against hazardous electrical  
shock caused when your body becomes a  
path through which electricity travels to  
reach ground. This could happen when  
you touch an appliance or cord that is ‘live’  
through faulty mechanism, damp or worn  
insulation, etc.  
OIL ALERT SYSTEM  
Theoilalertsystemprotectstheenginefrom  
low oil damage. This system automatically  
shuts down the engine and prevents engine  
restarting if the oil level falls too low.  
120 VOLT ONLY: This position sends full  
power to the 120V receptacles only. 240V  
power is not available. Use this position  
when powering 120V items only.  
Note:Whenthishappens,theengineswitch  
remains in the ON position. The oil alert  
system is wired into the ON/OFF Switch.  
120 + 240 VOLT: This position sends full  
power to the 120/240V receptacle. It also  
powers the 120V receptacles at reduced  
wattage capacity.  
If this system shuts down the engine, the  
engine will not start until you add oil. Add  
oil to engine (see Engine Oil, page 7).  
When protected by the GFCI, you may still  
feel a shock, but the GFCI should cut it off  
quickly. A person in normal health should  
notreceiveseriousinjury. Note:Infantsand  
very small children may still be affected.

down or run at a slower speed when the gen-  
erator is not being used to supply power. The  
Auto-idlesystemcanbeturnedONorOFFby  
arockerswitchonthecontrolpanel.Whenthe  
switch is in the OFF position, the engine runs  
at full speed all of the time. When the switch

toidlespeeduntilanelectricalloadisapplied.  
When a load is applied to the generator (an  
electricalitemispluggedinandturnedon)the  
engine speeds up to the preset speed required  
to produce the correct voltage.  
2. If the GFCI receptacle tests okay,  
restore power by pushing the RESET  
button back in. The test lamp should  
work at this time. IMPORTANT: You  
must press the RESET button firmly  
and fully. It should lock into place. If  
the GFCI does not lock into place, do  
not use receptacle. Contact a qualified  
electrician for repairs.  
IMPORTANT: A minimum current load  
of 1 Amp is required to disengage the auto  
idle solenoid and cause the engine to come  
up to speed for correct voltage. Powering  
items at reduced engine speed will damage  
generator and powered items.

• Keep fuel out of children’s  
reach.  
CHECKING OIL LEVEL AND  
ADDING OIL  
The circuit breakers protect the receptacles  
and alternator. Overloading generator will  
trip circuit breaker. A short circuit in item  
being powered will also trip breaker. If this  
occurs, unplug electrical load from recep-  
tacle. Let circuit breaker cool down. Push  
circuit breaker button to reset.  
Refuel generator in a well-  
ventedarea.Donotllfueltank  
in the dark. Do not refuel while  
engine is running. Unhook all  
electrical loads and shut off  
engine before refueling.  
Follow steps below to check oil level. Make  
sure engine is level and stopped.  
1. Remove dipstick (see Figure 6). Wipe  
dipstick clean.  
2. Insert dipstick into oil filler neck. Do  
not screw it in. Oil level should be at  
top of filler neck. Oil should cover most  
of dipstick.  
• Donotoverfillfueltank.Always  
allow room for fuel to expand.  
If you overfill tank, fuel can  
overflow onto hot engine. This  
can cause fire or explosion.  
After refueling, tightly close  
fuel tank cap.  
• Do not spill fuel. Fuel or fuel  
vapor may ignite. If fuel spills,  
make sure area is dry before  
starting engine.  
• Never smoke in refueling area.  
Never allow open flames or  
sparks in area.  
• Storefuelinapprovedcontainer.  
Store fuel in a well-vented area  
free of open flames or sparks.

3. Electric motors present a special prob-  
Note: Some motors require nearly the  
same wattage to run as to start. These  
items include saws, drills, hair dryers,  
and food mixers. See Chart 1 for typical  
appliance wattage examples.  
DETERMINING  
lem. They require up to three-times  
their rated wattage to start. Chart 2, be-  
low, shows starting watts for different  
size motors. For example: an electric  
motor nameplate states 5 amps at 120  
volts. 5 amps x 120 volts = 600 watts  
running. Multiply this figure by 3. This  
will show the starting watts needed. 600  
watts x 3 = 1800 watts to start. When  
figuring the generator load for motors,  
you must use the starting watts figure.  
Do not use the running watts figure.  
ELECTRICAL LOAD  
FOR GENERATOR  
You must decide what electrical load your  
generator can power. Do this before us-  
ing generator. Use the following four-step  
method. It will help you select a load that  
is not too large. Make sure total wattage of  
all electrical loads does not exceed rated  
wattage of generator. For rated wattage of  
your generator, see Specifications, page 5.  
Electric motors present a special problem  
when figuring load. Read Step 3 carefully.  
4. Add watts and starting watts of all  
items. This total must not be larger than  
the rated wattage of your generator.  
It is a good idea to have up to 25%  
extra capacity for future needs or extra  
equipment.  
Chart 1 - Typical Electric Appliance Wattages  
1. Make two lists of items you want pow-  
ered by generator. List all motors and  
motorpoweredappliancesinone. Listall  
lights, small appliances, etc. in the other.  
For standby service to home or building,  
only include items you must power.

2. Enter running watts of each item except  
motors. The light bulb or appliance  
nameplate lists its wattage. Remem-  
ber, 1KW = 1000 watts. Note: The  
nameplate may not list wattage. It may  
only list volts and amps. The formula  
for finding wattage is: Volts x Amps  
= Watts. For example: An appliance  
nameplate states 3 amps at 120 volts.  
3 amps x 120 volts = 360 watts.

2. Let engine run for two or three minutes  
after removing electrical loads. This  
lets engine cool slightly.  
CAUTION: The engine speed  
is preset. The throttle is locked  
in preset position. Do not adjust  
throttle. Preset position lets en-  
gine run at 3600 RPM under load.

IMPORTANT: Keep generator level when  
servicing.Neverturngeneratorupsidedown  
or stand it on end to service.  
Note: The wattage ratings for some  
electrical motors are misleading. They  
may require up to three-times their  
rated wattage to start. You must figure  
total electrical load wattage. Make sure  
total wattage of all electrical loads does  
not exceed rated wattage of generator.

WARRANTY INFORMATION  
KEEP THIS WARRANTY  
Model  
Serial No.  
Date Purchased  
Always specify model and serial numbers when communicating with the factory.  
We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our standard  
written warranty. We make no other warranty, expressed or implied.  
FIVE-YEAR LIMITED WARRANTY  
GASOLINE PORTABLE GENERATORS  
DESA Specialty Products™ makes no warranty with respect to the engine and engine components not of its manufac-  
ture. They are subject to warranties of their manufacturers. Robin warrants the engine. See engine owner’s manual for  
engine warranty information.  
DESA Specialty Products™ warrants each generator, excluding engine, of its manufacture, to be free from defects in  
material and workmanship for five years from the date of first purchase from an authorized dealer, provided that the  
product has been properly installed, maintained, and operated in accordance with all applicable instructions. The bill  
of sale or proof of purchase must be presented at the time a claim is made under this warranty.  
This warranty is extended only to the original retail purchaser. This warranty covers only the parts and labor required  
to restore this unit to its proper operating condition. Warranty parts must be obtained through factory authorized deal-  
ers and service centers for this product. These dealers and service centers will provide original factory replacement  
parts. Failure to use original factory replacement parts voids this warranty.  
This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that  
fail or become damaged as a result of misuse, abuse, negligence, accident, lack of proper maintenance, alteration,  
modification, tampering, contaminated fuels, repair using improper parts, or repair by anyone other than an authorized  
dealer or service center. Routine maintenance is the responsibility of the owner. Travel, handling, transportation, and  
incidental costs associated with warranty repairs are not reimbursable under this warranty and are the responsibility of  
the owner.  
To the full extent allowed by the law of the jurisdiction that governs the sale of the product, this express warranty  
excludes any and all other expressed warranties and limits the duration of any and all implied warranties, including war-  
ranties of merchantability and fitness for a particular purpose to five years from the date of first purchase, and DESA  
Specialty Products’™ liability is hereby limited to the purchase price of the product and DESA Specialty Products™  
shall not be liable for any other damages whatsoever including indirect, incidental, or consequential damages.  
Some states do not allow limitation of how long an implied warranty lasts or an exclusion or limitation of incidental  
or consequential damages, so the above limitation of damages may not apply to you.  
This warranty provides the original purchaser with specific rights. For information regarding those rights, please con-  
sult the applicable state laws.
