Connecting The Ground Wire; Operating Method - YAMADA 140 Series Instruction Manual

③Installing operation panel
Mount the operation panel on the front side of the mounting plate. Insert two bolts with wave spring washers
and tighten them securely. Then, perform final tightening on the two bolts temporally tightened above. (Fig. 7)
④Connect tubes according to the wiring diagram on P.15 and carefully verify that the lift can be operated
properly with the control switches.

2.5 Connecting the ground wire

- Make ground connection when working with flammable material or in explosive atmosphere. Rapid
pumping of material can result in static electrical charge. Also, be sure to provide proper ventilation
where a flammable atmosphere may exist.
1) When installing the pump, be sure to connect the ground wire at the
specified position. (Fig. 8)
2) Also connect ground wires to peripheral equipment and piping.

3) Use 2.0mm minimum ground wire.

3. Operating method

- Keep your face away from the bleeder valve. Material may spurt out together with compressed air.
- 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.
- Do not exceed the maximum operating pressure of the lift (0.4MPa). Overpressure may cause a
product failure resulting in serious personal injury and/or property damage.
- 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
"STOP".
- To prevent excessive pressure in a drum, do not push the "AIR" button when the lift control switch is
set to "STOP".
- Leave the lift control switch "DOWN" until a drum becomes empty. A suction failure may be caused if
the switch is set to "STOP". Also, if the "AIR" button is pushed when there is still material in a drum,
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.
