4 .3 Safety Summary 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 hoses. These safety precautions are given for your safety. Review them carefully before operating the tool and before performing maintenance or repairs. Supervising personnel should develop additional precautions relating to the specific work area and local safety regulations.. General Safety Precautions The PortaCo Inc. tools are designed to provide safe and dependable service if operated according to the instructions provided in this manual. Read and understand this manual and any stickers attached to the power unit before operating. Failure to do so could result in personal injury or equipment damage. Check the rules and regulations at your location. The rules may include an employer s work safety program. Regulations may identify hazards such as working around utility supply lines or hazardous slopes. Read and understand any manuals for additional or optional equipment, which maybe shipped with the tool..5 Warning and Caution Statements or maintenance procedures, practices, or conditions considered essential for the protection of personnel, equipment, and property. WARNING: HIGHLIGHTS A, ESSENTIAL OPERATING, OR MAINTENANCE PROCEDURE, PRACTICE, CONDITION STATEMENT, ETC WHICH IF NOT STRICTLY OBSERVED, COULD RESULT IN INJURY TO, OR DEATH OF, PERSONNEL OR LONG TERM HEALTH HAZARDS. CAUTION: HIGHLIGHTS AN ESSENTIAL OPERATING OR MAINTENANCE PROCEDURE, PRACTICE, CONDITION STATEMENT, ETC. WHICH IF NOT STRICTLY OBSERVED, COULD RESULT IN DAMAGE TO, OR DESTRUCTION OF, EQUIPMENT OR LOSS OF MISSION EFFECTIVENESS..6 Training Requirements Operator training for the weld shear should consist of information found in this manual. In addition the operator must receive instructions, both verbally and through demonstrations for applications in which the tool is going to be used. The new operator must start in an area without bystanders and use the tool until able to fully operate the tool under the conditions for the work area. Warning and Caution statements have been strategically placed throughout the text prior to operating

5 .0 INSTALLATION INSTRUCTIONS. Unpacking Instructions Upon receiving your weld shear promptly remove it from the shipping container. Always keep top side of container up. Inspect unit for damage which may have incurred during shipping and report it to carrier for claim.. Tool Preparations No preparation is required; the tool is ready to operate after it is removed from the shipping packaging..3 Testing WARNING: NEVER STICK FOREIGN OBJECTS, FINGERS, OR OTHER EXTRMITIES INTO MOVING MECHANISMS. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY LEAD TO SEVERE PERSONAL INJURY OR TOOL DAMAGE. Before operating the weld shear it is important to inspect the shear blades for excessive wear or damage. Replace the shear blades if required before operating the shear. Follow all safety precautions and procedures when inspecting tool. CAUTION: THE PRESSURE TESTING PROCEDURE MUST BE CONDUCTED BY A QUALIFIED HYDRAULIC TECHNICIAN. To test the pressure exerted at the shear blades, remove the shear blades from the frame. Insert a pressure testing system between the frame and the ram end frame of the shear. PortaCo's Model TS-00-X-O Tester Shear, is recommended for this procedure. (see figure.3a) The model TS-00-X-O tester is capable of testing most shears. It features a pressure gauge with and arrow indicating the optimum force applied. Position tester while closing the shearing mechanism, aligning the pins in the frames with the holes in the tester; pump the handle to advance the cylinders until the needle, on the pressure gauge, of the tester stops climbing. The needle should be within 500 psi of the red arrow. (figure.3b) When testing follow the instructions provided with the test equipment. Testers other than PortaCo. Inc.'s model TS-00-XX-O may instruct the technician to perform the test in a manor slightly different than the procedure just described. Figure.3A 5

8 3.0 Operating Instructions 3. Description of Power Tool PortaCo s model WS Weld Shear is intended to be used to shear Thermit and Buta type welds. It's light-weight construction and auto cycle valve reduces operator fatigue. The PortaCo Weld Shear secures to the rail at four points. Adjustable roller hold downs provide a smooth shearing operation and guide the shear on worn rail. Hold down assemblies have been designed to be easily serviced in the field. Fully guarded hydraulic plumbing protects the operator from accidental leakage of oil onto the welded area, reducing the potential for a fire. A double acting hand pump extends and retracts the cylinders for faster travel rate. The cylinder direction is controlled with a direction selector valve. Follow the instructions "DO NOT OPERATE SHEAR WITHOUT SHIELD IN PLACE" and "DO NOT STRIKE HOLD DOWNS" printed on this decal. (figure 3.A) (figure 3.G arrow A). Figure 3.A The mounting instructions decal is also located on the guard cover. It states the correct procedure for adjusting the hold down rollers. It tells the operator to "ADJUST ROLLER CLEARANCE TO /8" BELOW BALL OF RAIL". (figure 3.B)(figure 3.G arrow B) 3. Controls and Graphics The following decals are placed on the tool to aid in its operation and maintenance. The operator should locate and understand them before using this power tool. The weld shear has five instructional decals located on the tool. The "WARNING' decal indicates a practice which if conducted could result in injury to the operator or bystander, or damage to the tool. Figure 3.B On the inside of the far side of the frame, is a serial # decal. This decal has the serial number as well as the model number of the unit. Each unit has it s own unique serial number. It 8

9 is important to keep this decal protected and kept legible. The serial number is needed when ordering replacement parts. (figure 3.C)(figure 3.H arrow C) Figure 3.E The open-close decal indicates weather the jaws will open or close when the pump is being operated. (Figure 3.F) (Figure 3.G arrow E) Figure 3.C The caution decal is located on the guard attached to the frame. (Figure 3.D) (Figure 3.G arrow D) F E G A B D Figure 3.G 3.3 Before Operating Figure 3.D The hydraulic oil decal highlights the oil reservoir. (Figure 3.E) (Figure 3.G arrow E) Check that the guard is in position and securely fastened, and in good condition. Inspect the weld shear for any hydraulic oil leaks and repair as required, Do Not operate the shear if a leak is present, hydraulic oil on the weld area is flammable. Inspect the hold down assemblies, make sure they all operate properly. Replace any damaged or severely worn components before operation. 9

10 Hold downs which aren't operating correctly may result in an inferior sheared weld. reservoir fill cap is located on top of the tool next to the hand pump. (Figure 3.G arrow G) Inspect the shear blades and replace if severely worn or damaged. CAUTION: WHEN FILLING THE OIL RESERVOIR BE SURE THE JAWS ARE IN THE FULL OPEN POSITION. OVER FILLING OF THE RESERVOIR COULD RESULT IN THE TOOL NOT OPERATING PROPERLY AND OIL BEING FORCE OUT CAP/PLUG. 3. Positioning on Rail BAD "REPLACE" Place the shear over the weld, centering the weld between the shearing blades. Turn the handle on all four rollers to position each roller under the rail. GOOD WARNING: NEVER INSPECT PRESSURIZED HOSES, COUPLERS, OR FITTINGS WITH HANDS OR AT CLOSE DISTANCES. PRESSURIZED FLUID CAN PUNCTURE THE SKIN AND INJECT OIL INTO THE BODY RESULTING IN DEATH. Adjust the roller clearance to /8" below the ball of the rail using the nut to maintain the clearance. Check the oil level in the reservoir, the oil should be just below the bottom of the plug/cap. Always check the level when the jaws are in the full open position. The oil 0

11 - Set the directional valve to the open position. (Figure 3.5A arrow B) ADJUSTMENT NUT - Pump the handle until the jaws are full open. - Turn the hold down handles to release the rail and remove the shear from the rail. /8" CLEARANCE B A 3.5 Operating Instructions - Set the directional valve to the close position. - Insert the jack handle into the pump receiver tube. (Figure 3.5A arrow A) - Pump the handle until the jaws are closed and the weld is sheared. 3.6 Storage Preparation Store the weld shear on a smooth level surface. The tool should be stored in a cool, dry environment which is not subjected to rapid temperature changes.
