6. Disassembly and Assembly
CAUTION
- Gasoline is a high volatile fuel. Do not use it to clean the pump in any case, otherwise ignition or
explosion may be caused.
- Before disassembling and inspecting the machine, be sure to stop the supply air and open the outlet
valve to release the internal pressure of the pump.
- When cleaning pump parts, do not use a liquid that may corrode aluminum, copper ally, iron, etc.
[Separation of the air motor and the lower pump]
1) Shut off the air supply and release the pressure inside of
the pump.
2) Remove the air hose and delivery hose.
3) Remove the pump and let the material out from the
suction tube. The material inside of the suction tube can
be out by pushing the ball at the foot valve.
4) Grip the air motor part in a vise.
<Note>
The air cylinder is easily damaged. Do not fix it on the
vise in any case.
5) Loosen the lock nut.
6) Pull the lower pump and unscrew the cap nut that
connects the connecting rod and plunger rod. Then the
lower pump can be separated from the air motor.

[Disassembling the lower pump]
Disassembling the foot valve
7) Grip the knurling part of the suction tube on a vise. Set a
wrench on the foot valve and unscrew it to remove the
suction tube. (Fig. 7)
8) Remove the stopper pin at the foot valve and the ball
and wash it. If scratch or ware is found on the ball and
the seat, replace with new parts. (Fig.11)
Disassembling the intake valve
9) Grip the body of the lower pump on a vise. Set a pipe
wrench on the knurling part of the suction tube and
unscrew it. (Fig. 7)
10) Remove the stopper pin that connects the connecting
rod and the plunger rod and loosen the connecting rod
screw.
<Note>
Be sure to set a wrench on the two flats cut of the
plunger rod. Placing a wrench on a slide portion of the
rod could cause damage and trouble.
