Keep them away from sharp edges, exhaust manifolds, or other hot surfaces. Check for signs of abrasion or deterioration.
LP GAS COMPONENTS LP FUEL SYSTEM The LP fuel system consists of several components not found on the gasoline system. The LP fuel system also contains the associated mounting hardware and plumbing for the LP components. The major LP components are as follows: 1. Throttle plate & mixer 2. Combination water-heated vaporizer & regulator 3. LP fuel tank, valves & fittings These components are factory set; attempts at adjusting these components should only be made by authorized service personnel.
LP TANK COMPONENTS LP FUEL TANKS The LP tank is located under the driver’s seat. Use only the proper size and type of LP tank. The ATS 46/53 LP powered sweeper/scrubber uses a 33.5 lb. Liquid withdraw tank. The DOT designation of the tank is DOT 4BW240. Standard D.O.T. LP fuel tank sizes have 14, 20, 33.5, and 43.5 pound capacities. The liquid volume permitted in these containers is less than the total volume of the cylinder.
LP TANK CARE USE AND CARE OF LP TANKS If an LP tank is damaged or leaking, it should be immediately removed to a designated safe area and the proper personnel should be notified. Do not attempt to make repairs to the cylinder regardless of its condition. Repairs must be made by qualified personnel. The care an LP tank receives has a direct bearing on how long the tank can be used safely. LP tanks must not be dropped, dragged, or slid across any surface.
