HX Strut Pump Instructions
Before starting, let me impress upon you that servicing landing gear
struts with high pressure air or nitrogen is as safe as YOU make it.
Any time you have high pressure, you also have a certain amount of
danger.
Use Caution, stay clear, do not sit under the wing of a low wing
aircraft when you are servicing the struts.
WARNING: Wear safety glasses. You are dealing with high pressure
air and oil. Protect yourself!

Assembling the HX Strut Pump
The HX Strut Pump is assembled and tested prior to packaging and
shipping. To aid in shipping, the handle may have been removed.
The handle is usually strapped to the pump body along with the
hoses and inlet air fitting.
1. Cut the Zip-Tie that holds the hoses to the pump.
2. Remove the screw and washer from the top of the pump shaft.
3. Place the large hole of the handle over the top of the shaft.
4. Place the washer over the screw and place the screw into the
small hole in the top of the pump handle and thread into the shaft.
Tighten with hex wrench.
5. Choose air inlet fitting matching the air source (see table below) and
install on the short inlet air hose.
NOTE: The fitting must have 1/4 pipe male threads.
MAX AIR INLET PRESSURE 150 PSI
Note: Add several drops of Strut Fluid or #30 engine oil
into inlet port, or fitting to lubricate

Using the HX Strut Pump
1. Attach the high pressure fitting (Item #8) to the strut you intend to service.
NOTE: Make sure the fitting is attached firmly!
Hand tighten until solid contact with the strut seal is made. Then, if
needed, use tool to turn NO MORE THAN a 1/4 of a turn. No leakage is
permitted!
2. Extend the pump shaft to the full up position!
NOTE: This is to protect you and the plane from injury or damage
from the sudden extension of the pump piston and shaft.
3. Connect air inlet to source.
4. Operation as follows for air source:
(a) Air compressor with quick disconnect—Attach the air supply to the
HX inlet port with an appropriate coupler and proceed with pumping up
the strut.
(b) Tire inflator/bicycle tire pump—Attach the tire pump hose to the air
inlet (Item #5) of the HX pump. Raise the handle of the HX pump. Us-
ing the bicycle pump, pump five or more pumps of air into the HX
pump. Press down fully to displace air, forcing it into the strut.
NOTE: The more air you pump into the HX pump with the bicycle
pump, the more efficient the HX pump becomes.
(c) Spare Tire—Attach the low pressure supply hose to the pump inlet
fitting (Item #5). Next, attach the hose to the air fitting on the tire, air
tank or other similar air supply. You are ready to proceed. Pump the
pump as you would a standard tire pump. When the desired strut ex-
tension has been reached, disconnect the hoses in REVERSE order,
disconnecting the inlet source first. This will conserve the air supply in
the source tank or tire.
MAX AIR INLET PRESSURE 150 PSI
