3.3 Operation
CAUTION
-
Material, if containing air bubbles, may gush out when discharged. Put a plastic bag over the
material outlet to receive spurting material.
-
Do not exceed the maximum operating pressure of the pump (0.7MPa). Overpressure may cause a
product failure resulting in serious personal injury and/or property damage.
-
The maximum operating pressure of the lift is 0.7MPa. Overpressure may cause a product failure
resulting in serious personal injury and/or property damage. Do not exceed this limit.
At the “PRESS” mode, be careful not to put excess pressure on the lift. Material may escape
through the side of the packing around the inductor plate.
-
Keep your hand away from the three studs connecting the air motor and lower pump. Fingers can
get caught in the reciprocating plunger.
-
If a defect occurs during lift operation, immediately stop the lift by adjusting the lift control switch to
“DOWN” or shut down air supply to the unit.
-
Keep yourself away from the lift when operating it. Do not touch any part of the unit other than the
control switches.
-
Do not put your hand or any other parts of your body between a pail and the inductor plate when
installing a pail. An unexpected body injury may be caused.
-
To prevent excessive pressure in a pail, do not push the “AIR” button when the lift control switch is
set to “PRESS”.
-
If the “AIR” button is pushed when there is still material in a pail, air bubbles will be produced in
material.
-
When the lift stops due to a foreign object caught in the sliding part, be sure to move the lift to the
opposite direction BEFORE removing an object. The lift may suddenly start moving if a foreign
object is removed directly.

)
When filling the delivery piping with material for the first time, the air inside the piping will blow out. Please follow
the following procedure.
①
Put a plastic bag over the material outlet to receive discharged material.
②
Open the valve on the delivery piping.
③
Open the air valve for the pump and set the pump air regulator for minimum operating pressure.
④
The pump will start discharging material from the outlet. Once the air in the piping is released completely, close
the air valve for the pump and set the pump air regulator to 0MPa.
⑤
The pump is now ready for operation.

)
Adjust the pump air regulator to set to the desirable operating pressure. An estimate of the material discharge
pressure to the supply air pressure is calculated by “supply air pressure × pump ratio”.
(e.g. When operating a 38:1 ratio pump at 0.7MPa supply air pressure, material will be discharged at approx.
26.6MPa.)
<NOTE>
-
If the viscosity of the material is high or climate is cold, please switch the “lift control switch” to “PRESS”.
Pressure can be adjusted by lift air regulator in accordance with the viscosity of the material (up to 0.7MPa).
If the pressure is too high, the material may leak from packing of the inductor plate. Please set the optimum
pressure while operating (if the work is aborted, switch the “lift control switch” to “DOWN”).
-
Material viscosity changes with seasons. It is recommended to make a note of appropriate pressure for each
season.
