10.1 Inspection Items and Schedule
Perform maintenance and inspection at the schedules specified below.
This schedule assumes 8 hours of operations a day.
If the actuator is operated continuously day and night or at a higher utilization rate, shorten the inspection
intervals according to the situation.

*1 If the actuator is operated back and forth repeatedly over a distance of 30 mm or less, the oil film created by
the grease may be broken. As a rough guide, move the actuator back and forth five times or so over a
distance of 50 mm or more after every 5,000 to 10,000 cycles. This will restore the oil film. (If your ROBO
Cylinder has a stroke of less than 50 mm, move the actuator back and forth over a distance corresponding to
the entire stroke.)
10.2 Visual Inspection of the Exterior
In the visual inspection of the exterior, check the following items.
Actuator Loose actuator mounting bolts, etc.
Cables Scratches, connection at connectors
Spiral cover Scratches, dents, foreign attachments
Overall Abnormal noise, vibration
x If the actuator is fixed vertically, grease on the guide may drip depending on the environment. In this case,
clean the dirtied areas and add grease.
x The spiral cover is a consumable part. Its life is 2,000,000 cycles of back and forth operation as a reference.
Refer to 11.7 How to Replace Spiral Cover when replacing the spiral cover.
(Note) The life of the spiral cover varies due to the environment of use. Foreign object (dust, high-viscosity oil)
attached on the surface could disturb the expansion and contraction operation, which leads to a shorter
life. To obtain a longer life, clean the surface regularly.
