Assembly instructiOnsnote: For additional information regarding the parts listed in the following pages, refer to

the Assembly Diagram near the end of this manual.

wArning! Make sure the Air Hydraulic Pump is unplugged from its air supply and all pressure is released before making any adjustments to the tool.

note: The Pump comes fully assembled, but you will need to attach a hydraulic hose (not included) to the Air Inlet (9) located on the Pump Body (43) before using this Air Hydraulic Pump. This hydraulic hose (not included) is how you will attach all tools.

set up diAgrAm

recommended Air line components

hydraulic pump

Air compressor

note: For best service you should incorporate an oiler, regulator and in-line filter as shown in figure 1. If you are not using an automatic oiler system, before operation add a few drops of Pneumatic Tool Oil (not included) to the airline connection. Add an additional few drops after each hour of continual use. Hoses, couplers, oilers, regu-lators and filters are all available at Harbor Freight Tools.

OperAtiOn instructiOnsnote: This Air Hydraulic Pump is designed to operate either pneumatically or manually. It

is an ideal power source for various body, frame and alignment applications. It can be used with different ram kits, shop presses and hydraulic pullers (not included) that operate up to 10,000 PSI. It is equipped with a factory set Safety Valve to prevent sudden hydraulic failure. This Pump should be installed in a fixed location.

note: Check the oil level before using. The Pump Reservoir (46) should be full but after shipping it may need to be topped off. Check the oil in the pump reservoir prior to use. Remove the Filler Plug (36) and add the fluid being careful not to spill. Replace the Filler Plug (36) and wipe up any spilled hydraulic fluid. Periodically check the fluid level.

fOr best OperAtiOn: Before use, pull the Breather Valve (35) out. After use, replace the Breather Valve (35).

pneumAtic tOOl OperAtiOn

Depress Foot Pedal Release (34) with one hand while you lower the Foot Pedal (31) with your foot, locking it in the down position using the Hold-down Clamp (42).

With the Air Valve (47) in the released position, attach the air hose from your com-pressor to the Air Valve (47).

As pressure may be present, verify that the system is not pressurized before hy-draulic hoses are connected or disconnected. Verify this by pressing the Foot Pedal Release (34) to release any internal hydraulic pressure. Attach a hydraulic hose (not included) to the Air Inlet (9). You will attach all tools being used with your Pump to this hose.

Hold the lever on the Air Valve to apply pressure. Use the Foot Pedal Release to release pressure. The lever on the Air Valve (50) may be held down by the attached Lock Lever (A33). Disconnect the air supply after use.

mAnuAl tOOl OperAtiOn

If the Foot Pedal (31) is in the lowered position, take pressure off the Foot Pedal (31) using the Foot Pedal Release (34). Then using your hand, unhook the Hold-down Clamp (42) and let the Foot Pedal (31) raise to its full height.

Attach a hydraulic hose (not included) to the Air Inlet (9). You will attach all tools being used with your pump to this hose.

Pump the Foot Pedal (31) slowly but continually as you are using an attached tool. This will keep constant hydraulic pressure applied to the tool you are using.

Depress the Foot Pedal Release (34) to release hydraulic pressure.

inspectiOn, mAintenAnce, And cleAningwArning! Make sure the Air Hydraulic Pump is disconnected from its air supply and all hydraulic pressure is released before performing any inspection, mainte-nance, or cleaning procedures.

befOre use, inspect the general condition of the air hydraulic pump. Check for loose screws, misalignment or binding of moving parts, cracked or broken parts, cracked welds, cracked or broken hoses, leaking oil, and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, have the problem corrected before further use. do not use damaged equipment.

After use, wipe off with a clean moist cloth. Be sure to wipe away any spilled hydraulic fluid.

mOnthly, check and refill hydraulic fluid. (See note page 6.)
