Do not use the motor to rotate the output shaft of the reduction gear for safety, if possible. If the
motor is used by necessity, run the motor at a low speed and never touch the rotation section.
Otherwise, you could be caught by the rotation section, which will result in serious injury.
Step 9
• Repeat steps 3 to 8 until the reduction gear is filled with the same amount of lubricant as that was
drained.
Step 10
• It is recommended that the inside of the reduction gear is flushed so that the lubricant can be
replaced more efficiently.
• Remove the injector from the tapped hole on the supply side, and attach a hexagon socket head cap
plug to the tapped hole on the drain side. Calculate the output shaft conversion and set the motor
rotation speed so that the output shaft rotation speed is 5 to 10 rpm. Then, rotate the motor for about
one minute.
Set the rotation speed based on the output shaft conversion by taking the customer’s operation
conditions into account.
Step 11
• Perform steps 2 and 3 again.
Step 12
• Attach the plugs removed in step 2 above to the tapped holes for injecting/draining grease. Replace
with new seal tape.
• If the customer’s component is flush with the tapped holes for injecting/draining grease, tighten it
so that the plugs will not protrude from the edge surface.
Step 13
• Wipe off the lubricant adhering to the surrounding completely.
