6. WARNING !
Please don´t 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 adhered to properly.
· The pointer needle or pressure gauge has no change or changes slowly when inflated for a long time (Generally
speaking, the 0,5L standard container will hold up to 200 BAR when you pump for 420-450 times).
Reason: Air Leakage
Solving method: Put into water to find the leakage point.
· In the process of inflation, if pull up is heavy and at the end 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 tube and connect screw which is on the top of pump barrel (just
one screw), filling water or silicon oil into the tube, then reassemble the pump and rapidly inflate (without
container and test plug) for many times, this removes unwanted particles from the valve.
• Take apart the Level-3 piston set to find the reason for leakage, or change the O-ring.
In the process of inflation, 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 or damage or has some unwanted particles/
dirt etc.
Solving method (refer to pic-7.3): Open the check valve of the base plate with special spanner, and clean or
replace the check valve.

7. COMMON PROBLEMS & SOLVING METHODS
· In the process of inflation, 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 or damage or has some unwanted particles/
dirt etc.
Solving method (refer to pic-7.3): Open the check valve of the base plate with special spanner, and clean or
replace the check valve.
· The inflation 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: Pump must be inflated many times (without container or test plug). When complete add the silicon oil in
the pump. The oil must be drained clean to prevent any later ignition when using. So please ensure the oil will
be drained as much as it can.
· 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
inflation action becomes heavier and heavier.
8. ATTENTION
It is normal to hear a loud hiss and see water residue when you release the air which 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 container
valve as this be may not working properly, or the valve of the container has not been sufficiently tightened. If
the problem still exists then use a different container to determine whether the problem is caused by the pump
or container. If the problem is believed to be the pump then please refer to the instruction book accordingly, or
contact with the dealer responsible.
