Ⅶ.Trouble shootings
The normal problems for machine are:
1)The machine doesn’t absorb
liquid.
2)It doesn’t spray.
Please try the following solution:
1)Check if Inlet valve is in
stickiness or leakage. If inlet valve is
sticky, refer to fig.1. Push the dustpr-oof
plug inside the inlet valve. To fill water
into inlet valve and check whether it’s
leaky. If it’s leaky, contact supplier to
change it. |

2)Check whether the diaphragm is damaged. If
it is damaged, oil goes out from outlet hose
when it absorbs liquid, in additional, check
if there is any hydraulic oil in the pump.
Put this machine backward, loosen four fixed
bolts on valve assembly, remove them and
take out diaphragm to change.
It’s necessary to discharge air after changing
diaphragm. Please follow these steps:
Unscrew copper nut of pressure valve, turn
on the motor repeatly till air is out. To
check if the air is released, tighten copper
nut of pressure valve, remove inlet valve
and extend finger into the center hole of
inlet valve, gently touch the diaphragm, if
you can feel it’s vibrating, it means there
is no air inside Otherwise, repeat the
above. |
