I thought I would share with you the most common machine problem at the moment. It is " lacking power". This is a major problem as it drastically slows you down therefore takes you longer and uses more energy.
The main course is a dirty airfilter. During a dry dusty period it doesn't take long for dirty airfilters to restrict the air in flow. This reduces the engines power. So if this is happening to you check your airfilter, clean it or better still replace it.
Better still check out the following video.
