Assembly Instructions
Note: 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.

Compressor
Recommended Air Line Components
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, regulators
and filters are all available at Harbor Freight Tools.
Operation Instructions
Note: 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).

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 compressor
to the Air Valve (47).
As pressure may be present, verify that the system is not pressurized before hydraulic
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.

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.
