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. 

Universal Generator Cover: 

Heavy duty nylon cover 
fits over most models of 
4000W to 7500W gen-
erators.  A flexible han-
dle bar flap accommo-
dates most common 
handle bar designs. The 
cover keeps water, ice, 
snow, dust and dirt from 
damaging your genera-
tor 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 op-
eration.  The generator 
should be allowed to cool down for approximately 15 minutes after 
being shut down, prior to placing the cover over the generator. 

SAE 10W30 Motor Oil: 

A premium high performance 
formulation designed for high 
RPM small gasoline engines 
such as those used on genera-
tors.  This oil provides excellent 
protection against viscosity and 
thermal breakdown that often 
happens under the prolonged 
severe duty experienced by gen-
erator engines.  Use of this oil 
formulation is highly encouraged 
by the manufacturer.  Frequent 
oil changes with high quality mo-
tor 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 humid-
ity and ensures your generator is 
ready for use at all times.
