the pump shall be transmitted by a heavy duty, antifriction bearing type power takeoff through a heavy duty drive line or by live power from the engine. All mechanical operating mechanisms shall have an ultimate load capacity of not less than 20 times the maximum operating load. For ease of service, the hydraulic valve assembly, including relief valve, shall be located so that it will be accessible at all times and under all load conditions.

3.5.5.1 Hydraulic system. Relief valves shall be provided in the hydraulic system to prevent excessive hydraulic pressure and shall be set to relieve hydraulic pressure in excess of that recommended by the manufacturer. A hydraulic T-fitting, or equivalent, for insertion of a pressure gage, shall be provided in the line beyond the main relief valve to facilitate checking the line pressure. All circulating fluid shall pass through a full-flow hydraulic fluid filter. The filter element mesh shall be of a size to limit circulation of particles of 10 micron size or larger. The filter shall be located so that it will not contribute to pump cavitation and shall be accessible for servicing. Hydraulic lines, hoses, and fittings shall meet or exceed the requirements of Recommended Practices and Standards contained in the SAE Handbook. A reservoir shall be provided with sufficient flow volume to maintain the fluid temperature below the recommended limits and shall incorporate an oil level indicator.

3.5.5.1.1 Hydraulic cylinders. All exposed hydraulic cylinders shall be fitted with seals to prevent entrance of dirt, moisture, and other foreign elements and to preclude leakage of hydraulic fluid. The exposed portions of hydraulic ram piston rods shall be chrome plated with sufficient thickness to withstand a 30-hour salt spray test in accordance with

ASTM Designation B-117. The connecting ends shall be treated in the best commercial practice.

3.5.5.1.2 Hydraulic fluid. Unless otherwise specified, hydraulic fluid conforming to the manufacturer's standard or recommended requirements shall be provided in the hydraulic system. When specified (see 6.2), hydraulic fluid conforming to MIL-H-83282 shall be provided in the hydraulic system; and a permanent decal located near the hydraulic system fill port shall be furnished stating "CAUTION: USE HYDRAULIC FLUID CONFORMING TO MIL-H-83282

ONLY."

3.5.5.2 Controls. Controls for the packing mechanism shall be located at the curbside of the hopper opening and in the right hand drive area of the cab. The start and stop buttons for the compaction cycle shall be of different sizes and colors or the controls shall be of the interrupted cycle, deadman type. The start button shall be surrounded by a guard to prevent the accidental actuation of the compaction cycle. Controls for the rear dumping mechanism, when applicable,
