CHAPTER 5 Periodic Inspection
6-3-4 Replacing the Y-axis grease
(products manufactured from October 2009 onward)
1) Prepare the following tools and items.
• Daphne Eponex grease EP-0 • Hex wrench set
• Air tube coupler (PT1/8) • Air tube
• Grease nipple (A-MT8×1) • Grease gun
• Rag • Sealing tape (NITOFLON PIPESEAL)
2) Turn off the controller.
3) Place a sign indicating that the robot is being inspected, to keep others from
operating the controller switch.
4) Enter the safeguard enclosure.
5) Remove the X-axis arm under cover.
Refer to "7 Removing the Robot Covers" in Chapter 4 for removing the
covers.
6) Remove the plug on the top of the Y-axis arm. (See Fig. 5-31.)
7) To remove the old grease from the Y-axis, attach the air coupler (PT1/8)
into the screw hole where the plug was fitted and connect the air tube to the
air coupler. The old grease inside the Y-axis will be squeezed out by replen-
ishing new grease with a grease gun as explained in the next steps.
8) Remove the plug on the underside (section A) of the X-axis arm and attach
the grease nipple (A-MT8×1) there. (See Fig. 5-32.)
Keep the removed plug, as it will be used after replenishing grease.
9) Using the grease gun, supply the specified grease into the grease nipple un-
til the old grease is squeezed out from the upper tube.
10) When the old grease no longer comes out of the tube, remove the grease
nipple attached to the underside (section A) of the X-axis arm, and fit the
plug into place. When fitting the plug, wrap sealing tape around it to pre-
vent grease from leaking out.
11) After replenishing the grease, move the Y-axis arm by hand back and forth
a few times (about 90 degrees) and then remove excess grease.
12) Remove the air coupler, then fit the plug into place on the top of the Y-axis
arm and reattach the X-axis arm under cover. When fitting the plug, wrap
sealing tape around it to prevent grease from leaking out.
13) Go outside the safeguard enclosure.
14) Check that no one is inside the safeguard enclosure, and then turn on the control-
ler.
