4. Maintenance 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.
External visual inspection Greasing (Note 1)
Start of work inspection {
1–month inspection {
6-month inspection {
12-month inspection { {
Every 6 months thereafter {
Every 12 months thereafter { {
Note 1 • In an environment that the product is exposed in steam or hot water, earlier consumption of
grease is concerned. It is recommended to supply grease earlier.
• 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.
4.2 External Visual Inspection
An external visual inspection should check the following things.
䎃
Main unit Loose actuator mounting bolts, other loose items
Slider rod Lubricationg condition of grease, scratches on pipe
surface, deformation
Guide rod Scratchs on pipe surface, deformation
Cables Scratches, proper connections
Overall Irregular noise, vibration

4.3 Grease Supply
4.3.1 Grease applied on the Slider Rod
IAI uses the following grease in our plant.
Taiyo Petroleum Gas MEDALLION FM1(antibacterial grease)
Apart from above, there are equivalent sorts of grease sold in the market. For more detailed information,
ask the supplier to find an equivalent for you by telling them the name of the grease.
Warning: Do not attempt to apply fluorine and lithium grease. When mixed with lithium
grease, not only decrease the grease characteristics, but also may damage the
actuator.
