Services: (800) 77-8 Fax: (800) 7-8 Order Entry: (800) -8 Fax: (800) Form No Operating Instructions and Parts List for: -HHC -HHC HND HYDRULIC CUTTER TOOL INTRODUCTION The -HHC Hand Hydraulic Cutter Tool is a two speed cutter designed for cutting a wide variety of materials. The two speed pump provides a fast approach to the material with minimum effort. Cutting of the material is completed by continued pumping until the blades sever the part. The piston is retracted by lifting the lever slightly, pulling the trigger and pushing the lever down in a pumping motion. The cutter features insert type blades that can be easily replaced in the field with the use of only a screwdriver. Other features include a hinged flip top head and a full 0 degrees of head rotation. WRNING The -HHC is not to be used for hot line work.

2 Operating Instructions and Parts List, Form No , Back sheet of 7 IMPORTNT SFETY INFORMTION This is the safety alert symbol. To help prevent personal injury, 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 DNGER Denotes an imminently hazardous situation which, if not avoided, will result in death or serious injury. WRNING Denotes a potentially hazardous situation which, if not avoided, could result in death or serious injury. CUTION Denotes a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. CUTION Caution used without the safety alert symbol indicates a potentially hazardous situation which, if not avoided, may result in property damage. IMPORTNT Denotes an operating or service procedure or condition considered essential for expedient and efficient operation and service. WRNING It is the operators responsibility to read and understand the following safety statements, Only qualified operators should install, operate, adjust, maintain, clean, repair, or transport this machinery. Inspect tool before use. Replace any worn or damaged parts. Failure to observe these warning can result in severe injury or death. WRNING lways wear eye protection whenever operating hydraulic equipment. lways wear hearing protection as required. Operation, repair, or maintenance of hydraulic equipment should be performed by a qualified person who understands the proper function of hydraulic equipment per local directives and standards. Hydraulic equipment must be assembled correctly and then checked for proper function before use. Use hydraulic components of the same hydraulic pressure ratings. n appropriate hydraulic pressure gauge is recommended to monitor pressure. Never place your hands or other body parts near a hydraulic fluid leak. Never use your hands or other body parts to check for a possible leak. High pressure fluid can be injected under your skin causing serious injury and/or infection. WRNING Do not exceed cutting capacity of materials listed on sheet one. Cutting of too large or too hard materials could cause blades to shatter and cause injury. This tool is not insulated. When using this unit near energized electrical lines, use proper personal protective equipment. CUTION Do not cut piano or music wire. Do not operate cutter with top support open. IMPORTNT Properly dispose of all fluids, components, and assemblies at the end of their useful life. Hydraulic fluid should be compatible with all hydraulic components. Keep hands away from the cutter head assembly head when cutting.

3 Operating Instructions and Parts List, Form No Insert material to be cut between blades. OPERTING INSTRUCTIONS If part to be cut is very long, open cutter head by pulling out pull pin assembly, slide cutter over part and close head, locking in place with pull pin assembly fully engaged. Pump lever handle to close bottom blade on material. fter a few strokes, a slight click will be heard indicating that the pump has shifted into the high-pressure stage. Continue pumping lever until material has been cut. To retract piston, lift lever handle slightly and rotate handle clockwise until it stops. Push handle downward until pressure release plunger has been depressed and piston retracted. Lifting lever slightly at any time will stop piston retraction. Note: fter extended use or cutting hard materials, blades will become worn and pitted. Kit No. -8 is available from the factory for blade replacement. Replace worn or damaged blades to maintain safe, efficient cutting operations. Blade Replacement (Kit No. -8) To replace top blade, withdraw pull pin assembly and open top support. Remove slotted screw and top blade. Insert new top blade with flat side facing bottom blade and secure with new slotted screw and lockwasher. To replace bottom blade, advance piston until bottom blade screw is exposed. Remove hex socket screw and bottom blade. Insert new bottom blade with flat side facing top blade and secure with new screw. Close top support and replace pull pin assembly. Cutter is now ready for use. PERIODIC MINTENNCE: Occasionally lubricate pull pins and pivot pins with a molybdenum disulfide grease. The greatest single cause of failure for hydraulic tools is dirt. Extreme caution should be used to prevent the entry of contaminant's into the unit. Internal Relief Valve If cutter fails to cut properly when blades appear to be in good condition, the internal relief valve may have lost its proper setting (See Pressure Gage Port ) Pressure Gage Port This cutter features a port for the installation of a gage to determine the high-pressure relief valve setting. (See Gage ssembly) Oil Leaks slight weeping of oil from the ram and pump seals is normal and required to keep moving parts lubricated. Excessive leakage indicates a need for seal replacement. Seal Replacement Maintenance and repairs of this type should only be preformed by properly trained personnel in repair shops under clean conditions. In addition to all parts shown on keyed parts list, - Seal Kit and -0 are available for replacing seals in the cutter head sub-assembly and in the pump mechanism sub-assembly. Filling Reservoir To add or replace oil in the cutter, retract blade completely. Loosen the reservoir handle stop screw and remove the handle. Remove the reservoir plug and O-ring seal. Pull the stem of the reservoir bladder out as far as possible. dd oil until it fills the stem. See Compatible Hydraulic Fluids section. Sheet No. of 7 Rev Date: 0 Feb 00

Grip, Handle 7. Striker TROUBLE SHOOTING If the blade will not extend completely, and pumping becomes easier, it will generally be found that there is an insufficient amount of oil in the compressor's hydraulic system. This trouble can also be caused by faulty pump plunger packing or release valve packing by the pressure release valve being stuck open, or by foreign matter preventing the release valve balls from seating properly. Faulty packing will usually be detected by excess oil leakage around the pump plunger. stuck valve ball can usually be freed by rapping the tool sharply. CUTION void damage to other parts in the process of rapping. Foreign matter can frequently be flushed from a valve seat by pumping very rapidly with abrupt strokes. If the blade will not retract completely, it will generally be found that there is too much oil in the cutter s hydraulic system. Drain enough to permit complete retraction. If the blade will not retract and the oil reservoir is not full, the ram is likely being held by a deformed washer. small amount of leakage is desirable around the ram; pump plunger, and pressure release valve plunger to lubricate these parts. If enough leakage occurs to cause the oil to run, the packing should be replaced. Compatible Hydraulic Fluids: The use of moco Rykon MV oil is recommended. Compatible fluids include: Mobil DTE Mobil TF 0 Shell Tellus rco Dexron III Citgo W Citgo Dexron III Other fluids also may be used if they meet or exceed the following specifications: Viscosity: 80 SSU at 00 degree F. Flash Point: 0 degree F Pour Point: -0 degree F
