V. OPERATING INFORMATION

Hydraulic System

The auxiliary hydraulic system is an open type directly mounted behind the heavy duty variable displacement pump. This system consists of dual gear pumps that supply the required hydraulics to operate the full time power steering unit, boom control cylinders (lift, level, fold), the solution pump, mechanical agitation, and if equipped, hydraulic tread adjust.

After supplying each of these systems, the hydraulic oil is sent to the oil cooler in front of the engine coolant radiator. Here it is cooled and then sent back to the hydraulic oil reservoir.

NOTE:

Immediately shut down engine if low level hydraulic oil light comes on in cab (fig. 5.4).

DO NOT GO NEAR LEAKS. High pressure oil easily punctures skin causing injury, gangrene, or death. If injured, seek emergency medical help. Immediate surgery is required to remove oil. Do not use finger or skin to check for leaks. Lower load or relieve hydraulic pressure before loosening fittings.
