6. Discharge the specified amount of grease from the grease inlet or
grease exhaust port. (Refer to
.) In order to discharge the specified
amount of grease, receive the discharged grease by using a container,
and then measure the weight of the discharged grease by weighing
the container till the amount reaches to the specified amount.
Use one of the following methods to discharge grease.
Method 1: Extruding grease by air
(1) Connect the joint and the hose to the grease inlet.
(2) Connect the regulator to the grease exhaust port.
(3) Inject air from the grease exhaust port to extrude grease by air.
(Extrusion air pressure: 0.025 MPa or less)
(4) If the grease is not discharged enough by injecting air, operate the
manipulator about 5 times in the teach mode as shown in
10-6 “Grease Discharging Operation for Each Axis”
Method 2: Suctioning grease out
(1) Keep the inlet open and insert the tube into the exhaust port.
(2) Discharge grease by suctioning grease out of the exhaust port.
(Suction pressure: 0.025 MPa or less)
(3) If grease is not discharged by suctioning, operate the manipulator
again about 5 times in the teach mode as shown in
“Grease Discharging Operation for Each Axis”
