Hydraulic rock splitter in underwater use

Underwater using in hydraulic rock splitter:

The hydraulic splitter will work well underwater. Techniques are same as working above water, only the drilling is done using a compressed air drill. The tool has to be lubricated somewhat more frequently. We recommend that the plug and feathers are lubricated above water for each break. At the end of a working day. Remove plug and feathers and dry and wipe with oil rag to prevent rusting. If used in salt water, flush with fresh water first.
