• Study, understand, and follow all instructions provided with and on this device before use.

• No alteration shall be made to this device.

• Always wear protective gear when operating hydraulic equipment.

• Keep hydraulic equipment away from flames and heat. Hydraulic fluid can ignite and burn. Do not operate if leaks are detected.

• Crush Hazard.

Keep hands and feet away from loading area. Avoid pinch points or crush points that can be created by the load, cylinder, or any equipment of system.

• To avoid crushing and related injuries:

NEVER work on, under or around a lifted load before it is properly supported by appropriate means. Never rely on hydraulic pressure alone to support load.

WARNING

• Use only approved accessories and approved hydraulic fluid.

• Never attach ANY component not authorized by manufacturer.

• Always ensure that the chosen application is stable to work on and around.

• Do not connect to application which can return more oil to the reservoir than the pump reservoir can hold.

• Do not connect pump to hydraulic system powered by another pump.

• This device is not suitable for use as support device! As the system load is lifted, use blocking and cribbing to guard against a falling load.

• Clear all personnel before lowering load or depressurizing the system.

• Do not disassemble hydraulic cylinder, refer repairs to qualified, authorized personnel.

HYDRAULIC PUMPS

• The user must be a qualified operator familiar with the correct operation, maintenance, and use of pumps. Lack of knowledge in any of these areas can lead to personal injury.

• Do not exceed rated capacity of the pump or any equipment in the system.

• Never attempt to lift a load weighing more than the capacity of the cylinder.

• Burst hazard exists if hose or connection pressure exceeds rated pressure.

• Inspect pump, cylinder, hoses and connections before each use to prevent unsafe conditions from developing.

Do not use if damaged, altered or in poor condition. Do not operate system with bent or damaged coupler or damaged threads.

• Never hold or stand directly in line with any hydraulic connections while pressurizing.

• Use gauge or other load measuring instrument to verify load.

• Never attempt to disconnect hydraulic connections under pressure. Release all line pressure before disconnecting hoses.

• Do not subject the pump and its components to shock loads.

HYDRAULIC HOSES & FLUID TRANSMISSION LINES

• Avoid short runs of straight line tubing. Straight line runs do not provide for expansion and contraction due to pressure and/or temperature changes.

• Reduce stress in tube lines. Long tubing runs should be supported by brackets or clips. Before operating the pump, tighten all hose connections with proper tools. Do not overtighten. Connections should only be tightened securely and leak-free. Overtightening can cause premature thread failure or high pressure fittings to burst.

• Should a hydraulic hose ever rupture, burst or need to be disconnected, immediately shut off the pump and release all pressure. Never attempt to grasp a leaking pressurized hose with your hands. The force of escaping hydraulic fluid can inflict injury.

• Do not subject the hose to potential hazard such as fire, sharp objects, extreme heat or cold, or heavy impact.

• Do not allow the hose to kink, twist, curl, crush, cut or bend so tightly that the fluid flow within the hose is blocked or reduced. Periodically inspect the hose for wear.

• Do not pull, position or move setup by the hose.

• Hose material and coupler seals must be compatible with hydraulic fluid used. Hoses also must not come in contact with corrosive materials such as battery acid, creosoteimpregnated objects and wet paint. Never paint a coupler or hose.

• FAILURE TO HEED THESE WARNINGS MAY RESULT

IN PERSONAL INJURY AS WELL AS PROPERTY

DAMAGE.

BEFORE USE

1. Before using this product, read the instruction manual completely and familiarize yourself thoroughly with the product and the hazards associated with its improper use.

2. Know your pump, its limitations and how it operates before attempting to use.

3. Replace shipping plug (red color) with air vent plug (black color) before use.

4. Remove plastic cap from the air inlet port on the end of the pump, then connect with a 1/4” NPT air nipple (not supply with pump). Use teflon tape or similar thread sealant on thread connection.

NOTICE: When using the teflon tape or pipe thread compound. Tighten securely to prevent accidental removal of compound while in use. Take care not to introduce compound into port orifices.

OPERATION (for PA7550)

Always monitor pressure, load or position using suitable equipment. Pressure may be monitored by means of an optional manifold and gauge. Load may be monitored by means of a load cell and digital indicator.

Correct application position can only be determined by the operator of the equipment.

OPERATION (for PA7550M)

WARNING: To reduce the risk of personal injury and/ or property damage, hydraulic connections must be securely fastened before building pressure in the system. Release all system pressure before loosening any hydraulic connection in the system.

WARNING: Always monitor pressure, load or position using suitable equipment. Pressure may be monitored by means of an optional manifold and gauge. Load may be monitored by means of a load cell and digital indicator. Correct application position can only be determined by the operator of the equipment.

1. Connect air supply to the 1/4” NPT air nipple.

2. Remove manifold plug, connect to hydraulic hoses and suitable application.

3. Shift the valve to desired position. There are three positions available, refer to Figure 2 on below for the flowpath.
