Note: We supply the engine owner’s manual 
with generator. Refer to that manual for ques
-
tions concerning engine operation.
 DANGER: Never connect gen-
erator  to  any  existing  electrical 
circuits. The generator output will 
back-feed  into  the  utility  power 
line. This may electrocute a power 
company line repair person. Also, 
if generator is powering electrical 
circuits, the chance of an electri
-
cal fire exists.
  DANGER:  Use  only  in  well-
vented areas. Make sure  area 
has plenty of free-moving, fresh, 
outside air. Never run generator 
in an enclosed or confined area. 
Never  run  generator  inside  oc-
cupied building. Engine exhaust 
contains  poisonous  carbon 
monoxide gas. Overexposure will 
cause loss of consciousness and 
will lead to death.
120V, 20-Amp Duplex
USING RECEPTACLE
Note:  Do  not  exceed  amperage  rating  of 
receptacles. Exceeding rating  will trip re-
ceptacle circuit breaker.
Use receptacles properly. Improper use could 
damage generator. Use only grounded exten-
sion cords. Power only grounded or double-
insulated items. Do not overload receptacles. 
All generators (except model MGR2900) have 
the following receptacles (see Figure 8):
•  120V, 15-amp GFCI duplex receptacle
•  120V, 30-amp twist-lock receptacle
•  120/240V,  20  or  30-amp  twist-lock 
receptacle
•  120V, 20-amp duplex receptacle
Model MGR2900 uses only the 120V, 15-
amp GFCI duplex receptacle.
