SAFETY SYMBOLS Safety symbols and signal words, as shown below, are used to emphasize all operator, maintenance and repair actions which, if not strictly followed, could result in a life-threatening situation, bodily injury or damage to equipment. This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.
SAFETY PRECAUTIONS Tool operators and maintenance personnel must always comply with the safety precautions given in this manual and on the stickers and tags attached to the tool and hose. • Do not operate the tool with the wheel guard removed. • These safety precautions are given for your safety. Review them carefully before operating the tool and before performing general maintenance or repairs. Do not operate a damaged, improperly adjusted, or incompletely assembled grinder.
SAFETY PRECAUTIONS GRINDING WHEEL SAFETY • Ensure that the grinding wheel is correctly mounted and tightened before use. • Operate the grinder at “no load” for 30 seconds in a safe position and ensure there is no vibration or other defects detected. If considerable vibration or other defects are detected, stop operation of the tool immediately and determine the cause. Do not use the tool until the defect is corrected.
TOOL STICKERS & TAGS 25413 HG80 Name Tag 25414 HG80110B CAUTION DECAL 25556 HG80120B CAUTION DECAL 25610 Railroad Help Desk Sticker 05153 Stanley Sticker 03787 GPM Sticker 7–10 2000 PSI NOTE: THE INFORMATION LISTED ON THE STICKERS SHOWN, MUST BE LEGIBLE AT ALL TIMES. REPLACE DECALS IF THEY BECOME WORN OR DAMAGED. REPLACEMENTS ARE AVAILABLE FROM YOUR LOCAL STANLEY DISTRIBUTOR. The safety tag (P/N 15875) at right is attached to the tool when shipped from the factory.
HOSE TYPES The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hydraulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with Stanley Hydraulic Tools. They are: Certified non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover.
All hydraulic hose must meet or exceed specifications as set forth by SAE J517. All hydraulic hose must have at least a rated minimum working pressure equal to the maximum hydraulic system relief valve setting. This chart is intended to be used for hydraulic tool applications only based on Stanley Hydraulic Tools tool operating requirements and should not be used for any other applications.
HTMA / EHTMA REQUIREMENTS HTMA / EHTMA REQUIREMENTS HTMA HYDRAULIC SYSTEM REQUIREMENTS TYPE I Nominal Operating Pressure (at the power supply outlet) 4-6 gpm (15-23 lpm) 1500 psi (103 bar) TOOL TYPE TYPE II TYPE RR 7-9 gpm (26-34 lpm) 1500 psi (103 bar) 9-10.
OPERATION PRE-OPERATION PROCEDURES PREPARATION FOR INITIAL USE Each unit as shipped has no special unpacking or assembly requirements prior to usage. Inspection to assure the unit was not damaged in shipping and does not contain packing debris is all that is required. After installation of a grinding wheel a unit may be put to use. CHECK HYDRAULIC POWER SOURCE 1.
TOOL PROTECTION & CARE NOTICE In addition to the Safety Precautions found in this manual, observe the following for equipment protection and care. • Make sure all couplers are wiped clean before connection. • The hydraulic circuit control valve must be in the OFF position when coupling or uncoupling hydraulic tools. Failure to do so may result in damage to the quick couplers and cause overheating of the hydraulic system. • Always store the tool in a clean dry space, safe from damage or pilferage.
TROUBLESHOOTING If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem. When diagnosing faults in operation of the grinder, always check that the hydraulic power source is supplying the correct hydraulic flow and pressure to the grinder as listed in the table. Use a flowmeter known to be accurate. Check the flow with the hydraulic oil temperature at least 80 °F/27 °C. Problem Grinder does not run. Grinder operates too slow. Grinder operates too fast.
