11.1 Maintenance Schedule
Perform maintenance work according to the schedule below.

operation, shorten the maintenance intervals as needed.

*1 If grease is found deteriorated as a result of internal check, add grease.
*2 If the actuator is operated back and forth over a distance of 30 mm or less, oil film of grease may be broken.
As a rough guide, operate the actuator back and forth five times or so over a distance of at least 50 mm after
every 5,000 to 10,000 cycles. This should restore oil film.
11.2 Visual Inspection of the Machine Exterior
Check the following items when carrying out visual inspection.
Body Loose mounting bolts
Cables Damage to cables or connection to connector box
Stainless sheet Damage, foreign deposit or slacks
General Unusual noise or vibrations

If the stainless sheet is slacked, adjust it as necessary to eliminate the slacks.

As a rough guide, the stainless sheet will last for 5,000 km of traveling.
However, the stainless sheet should be replaced earlier, as deemed appropriate, depending on the specific
condition of use.
As a rule, the actuator must be brought to IAI to replace the sheet, or it must be replaced on site by IAI’s
service personnel.

If the actuator is secured vertically, grease applied on the guide may drip depending on the environment. If this
is the case, clean the soiled areas and add grease.
