NOTE
When the [ ] and [ ] keys are pressed simultaneously during a pump
operation, the pump operates at the maximum number of strokes while
the keys are held down. The air can be released speedily for all models
except the 6TCT and high-viscosity types.
When the liquid is not discharged even after air releasing
This may mean that the valve seat area (an area sealed by the check ball) on the discharge side or suction side is
clogged with foreign matter. Turn off the pump’s power, remove the joints, and wash the check balls and valve seats.
While taking care not to mistake the discharge side parts for the suction side parts and vice versa, reassemble the
parts while they are still wet into the pump head.
