(*1)
This unit is for suction and discharge of grease.
(*2)
Power supply is not required. Adjust the source pressure (supply pressure) to the specified pressure.
(*3)
Be sure to set the pressure less than 0.2MPa. Failure to do so may result in malfunction, such as the oil seal slipping off.
(*4)
Suction amount and suction time differs depending on the condition (charge of viscosity by the ambient temperature etc.) of robot and grease
(to increase the suction amount of grease, operate the robot at low speed or inching during suction).
If the grease is not getting sucked, then there is the possibility it has solidified.
In such a case, refuel and allow grease to flow before starting suction again.
Air flow starts when grease suction is completed. Stop suction when air starts flowing.
(*5)
Port sizes differs depending on robots.
