Troubleshooting

Problem

Cause

Solution

The pressure gauge needle 
don’t move or move very 
slowly after you pumping a 
while; and it goes back when 
you stop pumping. 

Air leakage

Put the hand pump into 
water. See the bubbles to 
check the leak point.

It will rebound and feels 
heavier and heavier when 
you pump to the bottom.

Something’s wrong with the 
piston in air tube

Replace the o-ring(NO.37or 
35) in the piston 1 (NO.38). 
Please turn ON the bleed 
valve and rotate the grip 
to dismantle it from the 
top. Take out the pin in top 
and dismantle the piston 
with the attached specifi ed 
dismantling device. Visual 
check if the piston seal is 
completely intact. If there’s a 
damage, replace the o-ring.

It feels very easy to pump 
when fi lling while the 
pressure gauge needle 
moves quite slow, barely 
don’t move.

The O-ring in the piston 
out of air tube is broken 
and causes a leakage in the 
bottom.

Replace the O-ring(NO.13) 
in the piston(NO.12). 
Please follow the steps 
above to dismantle the 
piston1(NO.38), Dismantle 
the air tube which 
connected to piston2(NO.2), 
so you can replace the 
O-ring(NO.13) in the piston 
(NO.12).

It’s very heavy to pump 
and disable to pump to the 
bottom. Even you pump to 
the end it will rebound.

Something’s wrong with the 
3rd-stage piston seal.

Change the 3rd-stage piston 
seal(NO.29/30). Please do as 
Q2 mentioned to dismantle 
Piston 1(NO.38). Pull out 
the 3rd-stage piston axis 
directly(NO.31), the broken 
3rd-stage piston seal or 
piston cover causes the 
above issue and it will be 
solved by simply replacing 
them.
