4. Maintenance and Inspection
4.1 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.

Note 1 If the actuator are operated back and forth repeatedly over a distance of 30mm or less, the oil
film created by the grease may be broken. As a guide, move the actuators back and forth
repeatedly for around 5 cycles over a distance of 50mm or more after every 5,000 to 10,000
cycles. A layer of the grease will recover.
Note 2 Visually inspect the stainless sheet everyday for looseness, etc. Adjust the stainless steel sheet
attachment in case of any looseness found on it.
[Refer to 4.7 “Procedures for Replacement and Adjustment of Stainless Steel Sheet”]
Note 3 Check the condition of grease, and wipe off the grease before supplying new in case it is
extremely dirty.
[Grease Supply Timing of Guide (Reference)]
Perform grease supply when it has reached to either the operation distance or spent months described in
the table below.

Caution:
x
An actuator after 6 months of storage may have caused a degradation of the
grease.
Supply grease before start using. [Refer to 4.6 “Grease Supply”]
x
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.
