Driving interface (screw size of port) is marked, drive and pre-compressed media
are connected. It is suggested that the precision of filter device should meet
our
requirements. Driving intake and oil mist device should lubricate the pump body itself.
(The oil mist device should add VG32 turbine oil, and other oil
will accelerate the
aging of seal parts.)

Pipeline requirements
According to the output pressure of the pump, we must select a pipeline that can
withstand the maximum output pressure of the pump.

Start-up
a. ensures that all interfaces are fastened and the original is installed in place.
b. adjust the pressure reducing valve and transfer the pressure to O psi.
c. Open the intake switch, slowly adjust the pressure relief valve until the pump
starts (under normal conditions, the starting pressure of the pump is 15-20 psi),
continue to adjust and observe the pressure gauge, to achieve the pressure you
need.

1
The pump does not
reciprocate, and the
muffler does not
exhaust or trace
exhaust.
1. reversing valve
stuck.
2. muffler jam
1. remove the reversing valve spring,
remove the spool of the reversing
valve, remove the contaminants, and
apply proper amount of lubricating oil.
2. remove the muffler and clean it up.
2
Pump does not
reciprocate, silencers
exhaust a lot of
exhaust.
Commutation valve
spool O ring wear
seriously
Remove the reversing valve circlip,
replace the worn seal with the new
seal, and apply the appropriate grease.
3
Pump action, but the
stroke is not in place,
pump frequently
abnormal or fast.
1. firing pin stuck.
2. firing pin O ring
off.
1. screw down the firing pin and use the
sharp nose pliers to remove the firing
pin and wipe it clean.
2. screw down the firing pin and reset
the O ring.
4
The pump operates
normally, does not
pressurized, or can
pressurized and
pressurized to less than
rated pressure.
1. there is a foreign
body in one-way
valve or one-way
valve.
2. the pressure
piston seal is
seriously worn.
1. check the check valve and clean up
the dirt.
2. after removing the check valve,
replace the pressurized piston seal.
