Using the Green Machines 636HS Air Sweeper is quite straightforward. First, make sure you have enough diesel fuel in the tank. Then, start the machine and use the windshield wipers, side mirrors, and backup camera to operate it safely. When using it, be aware of the crack in the windshield, and if it affects your vision, you may need to take extra precautions. As for maintenance, check the tires regularly, especially the 4 additional ones. Keep an eye on the running hours, and refer to the included manuals for more detailed maintenance procedures. Since it may have scratches and scuffs from normal use, clean it regularly to keep it in good shape. Remember, this item is for local pickup only at the MSU Surplus Store.
