WARNING
DO NOT disassemble any joint when there is residual gas, it is
dangerous to take apart the joint in this situation.
DO NOT put your hand near the air vent or point it at people when
you release the bleed valve screw, it can cause serious damage.
DO NOT add lubricating oil to the pump. Use appropriate grease
as necessary.

Install

Open the package and inspect all items. Read the instructions
before use. Familiarize yourself with proper operational method.
The wrong operation can be harmful to the user and may damage
the pump.
Loosen the belt on the pump, unscrew the bleed valve, pump up
and down 10 times to empty the pump. Tighten the bleed valve
and pump up to 200 bar (usually 6 times) then wait for 2 minutes
under 200 bar state to check whether there is leakage (check
pressure gauge needle). The best way to check for a leakage
point is to place the pump underwater.

Operation

1. Remove test plug from pump by pressing down on silver ring.
2. Before pumping, be sure the hose has no knots. Pull
and push the pump quickly. You will feel resistance when the
pressure in the container reaches 100 bar, this is normal.
3. Connect the pump to the container according to the
container's instructions.
Note: Before starting to fill the container, read the instruction
booklet about that container to ensure the correct amount of
pressure.
4. Check that the bleed valve is tightened correctly. Keep the
pump steady by standing on the base of the pump. Pull
and push the pump quickly to inflate the gas.
5. Open the bleed valve screw to relieve pressure in the hose.
Make sure the pressure gauge needle is at 0 before
disconnecting the container.
Note: You could directly open the bleed valve if the container
has a unidirectional valve. If your container does not have
a unidirectional valve, first turn off the valve to release residual
gas in the pump barrel and hose when filling the container. It is
normal to find small amounts of gas and water leaking from
the bleed valve.
6. Disconnect the pump from the container according to the
container's instructions.

High Piston

1. First to screw the nut off.
2. Use T spanner to take the pole out.

Common Problems and Solutions

Problem 1: The needle of pressure gauge does not move or
moves very slowly when pumping. Generally speaking a 0.5L
standard container should cause the needle to reach the 200 bar
when pumped for 420-450 times.
Reason: The needle has not moved or is moving very slowly is
because of a leak.
Solution: To confirm leak place pump underwater to find a
leakage point.
Problem 2: In the process of pumping, it pulls heavy and pump
automatically pumps down
Reason: The stage 3 piston has a malfunction
