12.1 Inspection Items and Timings
Perform maintenance and inspection at the timings specified below.
This schedule assumes 8 hours of operation 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.

12.2 Visual Inspection of Exterior
In the visual inspection of exterior, check the following items.
Actuator Loose actuator mounting bolts, etc.
Cables Scratches, connection at connectors
Spiral Cover
Scratches, dents, foreign object attached
on cover
Overall Abnormal noise, vibration
• The spiral cover is a consumable part. Its life is 2,000,000 cycles of back and forth operation as a
reference.
Refer to 12.7 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.
12.3 Cleaning
• Clean exterior surfaces as necessary.
• Use a soft cloth to wipe away dirt and buildup.
• To clean the spiral cover, use a soft cloth, etc., to wipe off soiling by working from the large
diameter side toward the small diameter side.
• Do not blow too hard with compressed air as it may cause dust to get in through the gaps.
• Do not use oil-based solvents as they can harm lacquered and painted surfaces.
• To remove severe buildup, wipe gently with a soft cloth soaked in a neutral detergent or alcohol.
