Testing
1. Insert the test plug (G) into the female quick disconnect (F)
2. Be sure the collar on the female tting snaps forward when installing,
securing it in place. In some cases, you may have to push the collar forward
into the secure position
3. Apply tension to the female tting in an attempt to pull it o of the male
tting to make sure the connection is secure. If for any reason the male and
female connectors separate during this process, contact Air Venturi tech
support at 216-220-1180.
4. Open the bleed valve (H) completely
5. Pump the handle rapidly about 20 times - you should face little/no resistance
during pumping. is ensures that there is no air built up in the line.
6. Tighten bleed valve (H) completely
7. Pump the handle rapidly until the gauge reads 100 bar/1450 psi
8. Open the bleed valve (H) to release air

@ AIR VENTURI 2017 / www.airventuri.com 216-292-2570
Operation
1. Before you start pumping:
2. Make sure the bleed valve is tightened completely.
3. Stand on the pump’s footplate to stabilize the unit.
4. Make sure hose is straight (no kinks or bends)
5. Connect the pump to the reservoir/airgun you want to ll with air.
6. Be sure the collar on the female tting snaps forward when installing,
securing it in place. In some cases, you may have to push the collar
forward into the secure position.
7. Apply tension to the female tting in an attempt to pull it o of the male
tting to make sure the connection is secure. If for any reason the male and
female connectors separate during this process, contact Air Venturi tech
support at 216-220-1180.
8. Start pumping by pulling the handle completely up, pause, then push pump
handle all the way down. e pressure will initially spike, and as you
continue pumping, it will rise slowly.*
9. As you continue to pump, you will experience increased resistance as the
pressure in the reservoir increases.
10. Repeat pumping until the gauge shows you’ve reached the desired pressure.
Be sure to not overheat pump.
11. Once desired pressure reached, open the bleed valve quickly to release the
remaining air in the hose. You may see water vapor/water drops when
bleeding out the air - this is normal.
Important: Open Bleed valve on pump quickly and fully, do not bleed slowly. is ensures the check
valve on the airgun or container closes completely and immediately.
If you are lling a scuba or carbon ber tank that has a shut-o valve, you will need to shut o the
valve before opening the bleed valve on the pump.
* Several quick strokes may be required to initially seat seals in some lling adapters and valves.
Once gauge shows gaining pressure, slow down to prevent overheating.

Using the spanner wrench, open the check valve in
the base plate. Clean or replace the check valve.

Pump up and down several times (without con-

test plug) aer adding the silicone oil. Any excess
oil must be drained from the pump through the
pumping action in order to avoid the possibility of
an explosion.

When you bleed the air from the hose, you may hear hissing and
the sound of water as the air is released. at’s the residual air le
in the hose. e larger the volume of air, the louder the sound.
If it’s exceptionally loud or louder than what you’ve previously
experienced, the check valve of the reservoir or container may not
be functioning properly.
It’s also possible the valve in the reservoir or tank may be defec-
tive, loose or not working properly. To ensure the check valve on
the gun or container closes completely and immediately, fully
and quickly open the bleed valve on the pump. Do not slowly or
partially open the pump’s bleed valve.
To determine if it’s the pump or the device that’s being lled, use
the pump to ll other tanks or reservoirs. If the other items do
not exhibit the same issues, then the pump is not the cause of the
problem.

Troubleshooting
Do NOT disassemble any joint when there is any
residual air in the pump! Doing so may be dangerous
and will void your warranty.
Do NOT put any part of your body near the bleed
valve air vent or point the vent at people or animals.
e blast of air and water may cause injury or damage.
Issue #1—e pressure gauge needle isn’t moving or
seems to be moving very slowly even though you’ve
been pumping for some time.
Cause: You didn’t close the bleed valve.
Solution: Close the bleed valve.
Cause: Air leak in the pump or hose.
Solution: Follow step 10 in “Testing” section to
nd the leak.
Issue #2—While pumping, the upward stroke is light
but the downward stroke is heavy...or the pump han-
dle pushes up by itself.
Cause: Faulty o-ring.
Solution: Refer to gure 7-2 to replace o-ring.
Issue #3— During pumping, the upward pull is very
heavy, and the pump handle is automatically sucked
back down without manual eort.
Cause: Dirt in the check valve.
Solution: Remove dirt from check valve.
Cause: Check valve in the base plate is damaged
or isn’t sealing for another reason.
Solution: Refer to gure 7-3 to replace or x
check valve.
Issue #4—Upward and downward strokes are unusu-
ally heavy.
Cause: Lack of oil.
Solution: Refer to gure 7-4 to properly
lubricate.
Issue #5—Pressure gauge needle doesn’t point to zero.
Cause: Defective pressure gauge.
Solution: Replace pressure gauge.
WARNINGS:
If you need technical or
maintenance help, call

Issue #2 --While pumping, the upward stroke is light
but the downward stroke is heavy...or the pump handle
pushes up by itself.
Cause: Faulty o-ring.
Solution: Refer to gure 7-2 to replace o-ring.
Solution: Test for slow leaks by putting the pump
base, hose and test plug in water to see if there
are bubbles, which indicate leaking air.
