Why is necessary for putting a generator cover on a portable generator cover?

 The duel fuel generator manufacturer should have told you that the generator machine can not be used indoor, or in garage. The right way is to use it outside the house.

But once the generator is exposed to the air for a long time, many situations will follow. For example: Sun exposure causes accelerated aging, Rain and snow seeps into the generator and causes damage, Dust and bird droppings make the generator look dirty, and so on.

So you need generator covers to keep the rain, snow, water, sun, dust, bird droppings out, to make your property last longer.
