3. INSTALL
Following the graphic, connect the pressure gauge, the output hose and the 8 mm (0.31 in) quick
connector using the special key.
Moderate strength can be applied but do not over tighten it as this could cause the sealing
ring between the pressure gauge / hose and base plate to be deformed and jammed. The rubber grip must
be tightened and should not be loose.
4. TEST
Step 1: Put the test plug into the 8 mm (0.31 in) quick
connectors, open the bleed valve (the bleed valve is in the
back of the base). Continuously pump air about 20 times
(in order to do that, pull the handle all the way up rapidly
and push it all the way down using your own weight).
Step 2: Tighten the bleed valve and pump until the
pressure is up to 100 BAR, then open the bleed valve
quickly to release the air. After that, tighten the bleed valve
again, inate the pressure up to 200 BAR. Please check
the pressure gauge to see if the needle has fallen. (If the
needle has fallen, there will be an air leak. The best way to
nd a leakage point is to put the pump, hose and test plug
under water together).
· It is important that you become familiar with the correct method of operation as the incorrect operation
could result in damage to the pump and possibly to the user.
· Please connect the pump and bottle, the connector will be supplied when you buy the bottle. Please
connect it according to the corresponding instruction manual.
Before starting to ll the bottle, please read the instruction manual to ensure the product is
properly used.
· Please make sure that the bleed valve is tightened.
When pumping the air, please be sure the hose is not knotted. Then pull and push the pump steadily. You will
begin to feel more resistance when the pressure in the bottle equals 100 BAR or above, this is normal.
· Please open the bleed valve screw to release the residual/excess air in the pump, barrel and hose. It is
normal to see a small amount of air and water leak from the bleed valve. You can easily remove the ller
probe/valve after releasing the air from bleed valve.

Please do not disassemble any joint when there is residual air in the pump, it is very dangerous to take apart
the joint in this situation.
Don´t put your hand near the air vent or point towards people when you open the bleed valve screw.
Serious damage could be caused if the above steps are not done properly.
· The pointer needle or pressure gauge has not moved or moved slowly when inated for a long time (Generally
speaking, the 0.5L (16.9 oz) standard bottle will hold up to 200 BAR when you pump for 420-450 times).
Reason: Air Leakage
Solving method: Put it under water to nd the leakage point.
· In the process of pumping, pulling up the handle is very hard and when it is pulled all the way up it automatically
sucks back.
Reason: Level-3 piston set has a problem.
Solving method (refer to pic-7.2):
• Please open the bleed valve, and take out the tube. Connect the screw which is on the top of the pump barrel
(just one screw), ll water or silicon oil into the tube, then reassemble the pump and rapidly inate (without
bottle and test plug) for many times. This removes unwanted particles from the valve.
• Take apart the Level-3 piston set to nd the leakage, or change the O-ring.
In the process of ination, pull up lightly but push down heavily or it will automatically run up.
Reason: The sealing of check valve at the base plate is not sealing, is damaged or has some unwanted particles/
dirt etc.
Solving method (refer to pic-7.3): Open the check valve of the base plate with the special key, and clean or
replace the check valve.

7. COMMON PROBLEMS & SOLVING METHODS
· In the process of ination, pull up lightly but push down heavily.
Reason: The sealing of check valve at the base plate is not sealing, is dimaged, or has some unwanted particles/
dirt etc.
Solving method (refer to pic-7.3): Open the check valve of the base plate with the provided special key, and clean
or replace the check valve.
· The ination action becomes heavier and heavier both for pulling up and pushing down.
Reason: The pump is in serious need of oil.
Solving method (refer to pic-7.4): Use silicon oil for maintenance.
Notice: The pump must be inated many times (without bottle or test plug). Once done please add the silicon oil
in the pump. The oil must be drained clean to prevent any later ignition when using it. So please ensure the oil
will be drained as much as possible.
· The needle pointer of the pressure gauge is not on zero position.
Reason: the oil is not drained clean, the oil expansion when the pressure reaches 20 Mpa can cause the
instantaneous pressure to reach up to 40 Mpa (overload) or has been destabilized during transportation.
Solving method: Replace the pressure gauge.
Pic-7.2 •Remove the dirt from the valve and replace
the O-ring when the pump automatically sucks back.
Pic-7.3 •Please clean or replace valve
when the pump automatically run up.
Pic-7.4 •Apply 2-3 drops of silicon oil when
ination action becomes heavier and heavier.
8.
It is normal to hear a loud hiss and see water residue when you release the air from the pump. This is residual
air stored in the pump and hose. The volume of the hiss depends on the amount of air being released. Normally
the volume of air released will not be too much, if the volume is too much, then check the bottle valve as this
may not be working properly, or the valve of the container has not been suciently tightened enough. If the
problem still exists then use a dierent container to determine whether the problem is caused by the pump or
the bottle. If the problem is believed to be the pump then please refer to the instruction manual accordingly.
