PROBABLE CAUSE
ACTION
The pressure does not increase
or increases slowly, even
though the product is correctly
connected.
Leakage.
Put the hose in water and
pump to see where air leaks
out.
The pump handle is stiff and
sinks automatically after it is
pulled up.
The non-return valve in the
three stage piston is not
working.
Open the venting valve on the
primary stage tube and drip a
small amount of silicone oil in
the tube. Close the valve and
pump rapidly a few times to
remove the blockage.
Open the three stage piston to
localise the leakage, or replace
the piston seal.
It is easy to pull up the pump
handle, but difficult to press
it down, or it moves up
automatically.
The bottom non-return valve is
defective, blocked or leaking.
Remove the bottom non-return
valve with a spanner and clean
or replace it.
It is more and more difficult to
pump, both up and down.
Inadequate lubrication.
Apply silicone oil.
NOTE: Pump a few strokes
after applying silicone oil to
press out any residual oil.
Excess silicone oil can cause an
explosion.
The pressure gauge is not
reset.
If there is excess oil in the
product the oil and gas will
expand when the pressure
reaches 200 bar. The pressure
will then quickly increase to
400 bar, which exceeds the
maximum permitted pressure
for the pressure gauge and will
damage it. The pressure gauge
can also have been subjected
to knocking.
Replace the pressure gauge.
