5. Maintenance and Inspection
5.1 Inspection Items and Schedule
Follow the maintenance inspection schedule below.
It is assumed that the equipment is operating 8 hours per day.
If the equipment is running continuously night and day or otherwise running at a high operating
rate, inspect more often as needed.

*1
Continuous return operation within a distance 30mm or less may cause the grease film to
degrade. As a guideline, in every 5,000 to 10,000 cycles, have approximately 5 cycles of
return operation over a 50mm distance or more. This will regenerate the oil film.
*2
In order to maintain the waterproofing, grease the scraper part on a regular basis. Failure to
do so may cause malfunction.
Caution:
An actuator after 6 months of storage may have caused a degradation of the
grease.
Supply grease before start using. [Refer to 5.5 “Grease Supply”]
Degradation speed of grease may differ depending on the environment of use
(temperature, humidity and ambient conditions). It is recommended to shorten
the grease supply period if the actuator is used under a bad condition such as
in high temperature, high humidity or in dusty ambience.
Also, it is recommended to improve the environment conditions in case the
grease changes its color due to the bad condition of use.
