Step 4
• Attach a grease nipple, etc. to the tapped hole for injecting/draining grease and then attach the
injector. (Refer to Fig. 7-2)
Step 5
• Using the injector or the like, fill the lubricant through the tapped hole for injecting/draining grease
on the supply side.
• When filling the lubricant, be sure to remove the plug for the tapped hole for injecting/draining
grease on the drain side.
• When pneumatic pressure is used for filling the lubricant, set the pressure below 0.03 MPa.
If you fail to remove the plug for the tapped hole for injecting/draining grease on the drain side, the
internal pressure increases. As a result, oil seals could fall off or the oil seal lip could be reversed.
If the internal pressure of the reduction gear increases, oil seals could fall off or lubricant could leak.
Step 6
• Inject the lubricant until it overflows from the tapped hole for injecting/draining grease on the drain
side.
Step 7
• Remove the injector from the grease nipple and plug the tapped holes for injecting/draining grease
on both the greasing and drain sides.
Step 8
•
Rotate the output shaft of the reduction gear by 1 or 2 turns.
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.
