Product Specifications
The document details various models of hydraulically-driven pressure washers, specifying maximum gallons per minute (GPM) and pounds per square inch (PSI) for each model. Features include forged brass head triplex pumps, hydraulic motors, adjustable unloaders, and chemical injectors.

Installation and Operation
Pressure washers can be installed on tractors with specific hydraulic systems. The water supply must meet certain flow requirements, and the pump includes an unloader valve and bypass system to prevent overheating. Proper installation and operation are crucial to avoid damage and ensure safety.

Unloader Valve Instructions
The unloader valve is factory set to 2000 psi and should not be tampered with. Instructions are provided for priming the pump and adjusting the hydraulic system to achieve the correct pressure.

Hydraulic System Operation
Different types of hydraulic systems are explained, including open center, closed center (pressure compensated), and closed center load sensing systems. Proper flow control is emphasized to prevent overheating and ensure efficient operation.

Maintenance and Repair
Regular maintenance includes checking oil levels, inspecting hoses, and performing routine inspections. Detailed instructions are provided for pump repair, including plunger and packing replacement, valve replacement, and hydraulic motor repair.

Hazardous Substance Alert
Proper procedures for handling hazardous substances are outlined, including draining and flushing the pump before servicing or shipping. Safety precautions are emphasized to prevent injury or legal issues.

Additional Safety and Operational Guidelines
Users are advised to avoid pumping flammable fluids, ensure proper grounding, and use appropriate protective equipment. Guidelines for operating temperature ranges and securing discharge lines are also provided.
