printer-friendly FAQs - Hy-Ram® Traditional Hammers The following FAQs apply to our Allied Hy-Ram® series of products. For other categories, please click here. How do I identify which Allied Hy-Ram I have? (See this page for information) What styles of demolition tools are offered and which ones are best for me? (See this PDF for information) Why does my hammer use a nitrogen gas pre-charge and how much gas should be in it (See the Nitrogen gas specifications for information) How should I grease my hammer, how much grease should I use, and what type of lubricant is required? Each Hy-Ram hammer is equipped with 1 (one) lubrication fitting.  The lubrication fitting will be located on the front side of the hammer that faces the operator while seated in the carrier.  Lubrication should be injected at 2-hour intervals or at any time that lubricant flow is not present on the shank of the demolition tool.  Allied Chisel Paste is recommended for superior tool lubrication and should be used during the Hy-Ram® lubrication procedure. Can I operate my hammer underwater? Underwater operation is possible only with the use of an underwater kit. My hammer is lacking in performance, what should I check? Up to 75% of the Hy-Ram's impact power comes from the nitrogen gas pre-charge.  In addition to the nitrogen, the hammer’s input oil flow and pressure should be verified to be within the operating range.  Related documents: Nitrogen gas specifications and Oil flow & pressure specifications. Why does my hammer slow down or stop during operation? These symptoms are generally associated with a lack of sufficient carrier down pressure, a lack of hydraulic input operating pressure, or too much nitrogen pre-charge pressure.  Related documents: Nitrogen gas specifications and Oil flow & pressure specifications. Why are my whip hoses pulsating more than normal? While some whip hose movement is typical, abnormal or severe pulsations are generally attributed to a high-pressure accumulator issue.  The high-pressure accumulator contains a nitrogen charge that must only be serviced by trained personnel using the proper tools.  Related documents: High-pressure accumulator charge procedure and High-Pressure accumulator charge specifications.     Updated: 5/5/2003 10:15:56 AM Questions?
