Joint #1, 2, 3, 4, 5, 6 Reduction Gears
As a rough indication, perform greasing at the same timing as overhaul.
However, it may vary depending on ambient temperature, usage condition and degree of the load (such as when operated with the
maximum motion speed and maximum acceleration / deceleration in continuous operation) applied on the Manipulator.
• Before greasing, move the Manipulator so that the grease inlet is not directed down.
Do not remove the grease plug while the grease inlet is directed down. Otherwise the oil content separated from the
grease may leak out.
• Do not use any tool to install and remove the grease nipple and grease line extension jig.
Always handle them directly by your hand.
If the grease nipple or grease line extension jig is installed or removed with a tool such as wrench, they may be
damaged.
