printer-friendly FAQs - AR Series™ Hammers The following FAQs apply to our AR Series Hammer products, for other categories please click here. How can I identify which Allied AR hammer model I have? The Allied AR Series hammers have been named to reflect the diameter of the demolition tool in millimeters.  For example a 75mm demolition tool is used in the AR 75. How should I grease my hammer, how much grease should I use, and what type of lubricant is required? Each AR Series 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.  The tool must be fully compressed into the hammer by the carrier during the lubrication process. 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 demolition tool lubrication. Which AR Series hammers use a nitrogen gas pre-charge and how much gas should be in it? Models AR 48 & AR 62 use a nitrogen pre-charge.  See the related document: AR 48 & 62 technical specifications. Why does my AR Series hammer slow down or stop during operation? These symptoms are generally associated with a lack of hydraulic input operating pressure, or too much nitrogen pre-charge pressure.  See the related documents: AR 48 & 62 technical specifications and AR 70, 75 & 95 technical specifications. My hammer is lacking in performance, what should I check? In addition to the nitrogen pre-charge on AR Series models 48 & 62, the hammer’s input oil flow and pressure should be verified to be within the operating range.  See the related documents: AR 48 & 62 technical specifications and AR 70, 75 & 95 technical specifications. How can I easily switch my AR Series hammer between a skid-steer and mini-excavator? Allied offers a conversion bracket that will allow a mini-excavator mounted AR Series hammer to be pinned onto a skid-steer style bracket.  We call it an XSF conversion bracket.  This bracket provides two mounting positions to facilitate horizontal or vertical hammer operation.  An additional valve may be added to the skid-steer conversion bracket to control the skid-steer's hydraulic output to match the AR Series hammer input requirements. What makes an Allied AR Series hammer different from an Allied Hy-Ram® hammer? The AR Series hammers have been designed to provide simple, reliable performance.  The AR Series hammers are offered as a more economical choice with fewer operational features compared to the Allied Hy-Ram series.   Updated: 5/1/2003 8:36:38 AM Questions?
