Maintenance
Cleaning
In order to ensure the Manipulator functions well, it should always be thoroughly cleaned after every use.
Always use fresh water at standard line pressure (700kPa/100psi max). Always make sure to drain any
water from the bellows port (small hole) on the front of the housing. Failure to clean properly could result
in premature corrosion of components.
Cutter Blades
Post-Deployment
The cutter blades are made from specially coated steel that will resist corrosion in salt water. However,
due to the extremely corrosive nature of seawater on even the noblest materials, the blades should be
properly cared for after use:
1. Cleanse with freshwater after every use.
2. Dry the blade and apply machine oil or grease to all surfaces.
Failure to care for the blade as described above will result in premature degradation.
Sharpening
If the cutter blades need to be re-sharpened, they can be sharpened numerous times using standard
methods. Always make sure to leave a perfectly straight edge
– irregularities or loss of perpendicularity
could result in compromised cutting ability. For replacement blades contact your Eddyfi representative.
Compensation Oil
The Manipulator unit is pressure compensated with light, food safe oil to ensure reliable operation at
depth. If a new manipulator has been sitting on the shelf for an extended period of time, or has recently
been shipped via air, it is possible some of this oil may “weep” out of the o-ring grooves. This can be
alarming as it will appear as though the unit is leaking; in most cases, though, it is nothing to worry about.
To verify if there is a leak in the unit, perform the following procedure (this same process should be
repeated annually to ensure the integrity of the housing seals):
1. Wash the Manipulator body with hot soapy water (dish detergent work best) and heat the body up
to 40°C to 50°C (Approx. 104°F - 122°F). The soap will remove any oil, and the hot water should
help with moving the oil from the cracks.
2. Allow the unit to dry
3. Place the dried unit on a facial tissue (or similar) in a warm area; if oil marks or slicks appear on
the tissue within a few minutes it could indicate a failure of one of the housing seals. Contact your
customer service representative to arrange for repairs.
At least once a year, check the quality of the oil by completing the following steps.
