Hi Scott, the machine does not operate on a forward motion that is why you will experiencing difficutly when trying to push forward.Activate the spray button as you move the machine back aross the floor and to move it forward lift onto rear wheels.
Spray an area of approx 3 sq yards with pro chem pre-treat using a hand spray pump,then agitate area with brush, then using machine with pro chem clean n rinse fluid pull machine across the same area,repeat this action until the area you intend to clean is complete.
dont forget to order your extention hose.
Please ask me as many questions as you please, ie advice where to buy cleaning fluids ext hose etc. Paul
