The GreaseMax design is fail safe: the starter cap cannot be screwed in without turning the activator screw down, which in turn can only break the seals and release the controlling element into the chemicals. The only possible result then is the production of gas which must push the piston forward and the lubricant out. The gas is retained in a gas tight neoprene bag and also as part of the fail–safe design by the gas tight seals on the piston and the double O–rings on the starter cap.
However, to be assured, check the following:
- Verify the bearing condition with the Condition Monitoring program
- Check the bearing temperature.
- A fresh discharge of grease around the seals will normally be visible
