1.1 Precautions

There is a large torque about the gimbal axis when the Seakeeper is precessing. Seakeeper cover panels are provided to prevent personnel or equipment from contacting the Seakeeper while it is in operation. These covers should not be stepped on or have anything placed on top. The covers should always be in place during operation.

_____________________________________________________________________________________________________

If it is ever necessary to access the Seakeeper while the flywheel is spinning, the Seakeeper must be locked at the display to stop the Seakeeper from precessing.

_____________________________________________________________________________________________________

Stand clear of the Seakeeper and all moving components.

_____________________________________________________________________________________________________

The unit may be started remotely. Assume it could move without warning.

_____________________________________________________________________________________________________

The following must be true before accessing the Seakeeper:
* Input power must be disconnected for at least 10 minutes
* It must be locked
* Flywheel must be at zero speed

1. Seakeeper must only be lifted from the supplied lifting eyes (see Section: Transport and Unpacking).
2. Seakeeper flywheel is supported by precision bearings. Make certain while unpacking and lifting Seakeeper assembly to NOT drop or impart mechanical shock as damage to bearings could result.
3. While handling / installing Seakeeper assembly, protect exposed hydraulic brake cylinder rods (See Figure 1) from scratches or damage as this could lead to premature seal failure and oil leaks.
4. While handling / installing Seakeeper assembly, do not allow electrical fittings that exit bottom of Seakeeper enclosure to come in contact with any surface or object as this could damage the fittings and potentially affect the vacuum integrity of the enclosure.
5. Exercise care to protect the painted finish as damage to finish could lead to early appearance degradation of installed Seakeeper.
