Pressure Relief Procedure
1. Close the fluid supply inlet; make the
pump circulates out all of the internal uid.
2. Close the bleed-type air valve first, and
open the uid outlet valve or trigger the gun
to relieve pressure and open the drain valve
3. After above steps, the pump would operate
slowly until the pressure relief completely.
4. Close the uid outlet valve.
Leave the uid drain valve open until you are
ready to pump the fluid again. If the hose is
completely clogged, or pressure has not been
fully relieved after following the steps above,
very slowly loosen the hose and coupling
and relieve pressure gradually, then loosen
completely. Then clear the hose.
FLUSH THE PUMP BEFORE FIRST USE
The pump is tested with lightweight oil,
which is left in to protect the pump parts. If
the uid you are using may be contaminated
by the oil, flush it out with a compatible
solvent.
To clean any settled particles out of the
system, ush the entire system after a period
of time. (Recommended 90 days or less).
PRIME THE PUMP
1. Close all of the air valves.
2. Close all of the Fluid valves (uid valve and
uid drain valve.)
3. Check all tting components in this system
are tightened.
4. Connect the air supply line to the air inlet
of pump.
5. Connect the uid inlet to the uid source.
6. Open the bleed-type air valve.
7. Adjust the pressure of air regulator to 2~4
bars.
8. Open the uid outlet valve slowly; operate
the pump until the fluid is pumped out
steadily.
To reduce the risk o injury, please always
follow the pressure relief procedure.
NOTICE: Please do not make the pump run
dry. Too fast operating could reduce the life
of the pump and damage the pump. If the
pump operates too fast, please reduce the
operated air pressure.
