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 inated 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 inate (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 ination, 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 ination, 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 ination 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 inated 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
ination action becomes heavier and heavier.

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 suciently tightened enough. If the
problem still exists then use a dierent 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.
