Periodic Maintenance Items
These maintenance items should be done prior to using the RiverPro/RioPro.
I/O Cable Connector Lubrication
The I/O connectors require very little maintenance. They are designed to be used in harsh environments
and thus limited amounts of dirt and grit do not affect their performance.
Prior to each connection:
1. Use light amounts of silicone lubricant (such as 3M
TM
Silicone Lubricant (Dry Type) ID No: 62-
4678-4930-3) on both the male pins and female socket to help seat the cable connectors. Wipe off
excessive silicone spray from the metal portions of the pins.
Regular lubrication is required
: Apply
dry type silicone lubricant prior to each connection.
Use ONLY silicone based lubricants. DO NOT use
petroleum based lubricants.
2. After lubricating, fully connect the male and I/O cable female connector in order to spread the
lubricant onto the pins and in the sockets. Wipe away any excess lubricant off the outside of the
connector.
3. To confirm that the lubricant has been sufficiently applied, disconnect the cable and check for lub-
ricant on all male pins (rubber portion). If the male pins do not have lubricant on them, apply
more lubricant and then reconnect the I/O cable.
The dummy plug should be installed any time the cable is removed. Use the dummy plug
when the RiverPro/RioPro is in storage or is being handled.
