Using the L.T. Rich Z - Spray Z - Max is straightforward. First, fill the 60 - gallon tank with the appropriate liquid. Then, start the Delavan Powerflo pump to get the spraying process going. When using it, make sure to operate it in a well - ventilated area. Since it's a used item, be aware that it may have some scuffs, but they shouldn't affect its performance. For maintenance, regularly check the pump for any signs of wear and tear. Also, keep the tank clean to prevent clogs. Remember, this item is untested, so it's a good idea to do a quick check before full - scale use. And don't forget, it's only available for local pickup at the MSU Surplus Store.
