3 1.0 INTRODUCTION 1.1 General Information This manual presents removal, operation, and maintenance information for PortaCo s model WS Weld Shear. The tool is designed to remove the excess material when performing Thermit and Buta type welds. It's light weight compact size allows for use inside rail pulling equipment. All hydraulic plumbing is protected by a one piece guard to prevent damage and to contain any leaks if any damage occurs. When properly used this tool will help reduce back strain and also reduce operator fatigue. PortaCo, Inc. reserves the right to make changes at anytime without notice and without incurring any obligation. 1.2 Features The main features of the PortaCo Weld Shear Model WS are as follows. Standard unit: Length in/ 67.0 cm Width in/ 45.1 cm Height 7.21 in/ 18.3 cm Weight 84-lbs/ 38.1 kg (includes blades) Upper ambient operating temperature 110 F (43 C), lower ambient operating temperature -20 F (-28 C). PortaCo, Inc.'s weld shear features an auto cycle valve which returns the shearing blades to the full open position when the valve control lever is released. (See figure 1.2A arrow A) This reduces total shearing time and reduces the operator's exposure to the heat produced during the welding procedure. Figure 1.2A C The control valve also limits the speed for shearing and provides a rapid retract for easy operation. The hydraulic plumbing is protected by a one-piece guard to prevent damage and to contain any leaks if any damage occures. (figure 1.2A arrow B) B The hydraulic quick connect couplers are located at the rear of the shear and directs the hoses along the rail out of the work area. (figure 1.2A arrow C) The path of the hose's along the rail reduces the potential for a worker to trip on them. Roller hold-downs, provide a secure mount to the rail and allows smooth operation during the shearing process. The roller height is set with a jam nut providing a snug fit on any size rail. (figure 1.2B arrow A) A 3

WHICH IF NOT STRICTLY OBSERVED, COULD RESULT IN DAMAGE TO, OR DESTRUCTION OF, EQUIPMENT OR LOSS OF MISSION EFFECTIVENESS. 1.6 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. 2.0 INSTALLATION INSTRUCTIONS 2.1 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. 2.2 Tool Preparations The PortaCo G-18D55-53-W power unit is recommended for hydraulic supply. This unit is equipped with two 5-gpm/20 lpm circuits that can be combined for on 10 gpm/40 lpm circuits. If the tool is used in cold weather, preheat the hydraulic fluid by running power source at low engine speed. Fluid temperature should be at or above 50 F/10 C (400-ssu/82 centistroke) before use, when using recommended fluids. Using too thick of fluid may result in tool damage. 2.3 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. To test the function of the shear, connect the hydraulic hoses to the tool see section 2.6 of this manual for proper procedure. With the flow from the power source "on" press the control lever down and hold it there. (See figure 2.3A) The shear blades should close at a slow rate of speed. Allow the blades to contact each other. Release the lever and the shear blades should move to full open without touching the lever or any form of assistance. 5

6 If the shear fails to complete any of these functions see the trouble shooting section of this manual. The needle should be within 500 psi of the red arrow. (figure 2.3C) 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 2.3A CAUTION: THE PRESSURE TESTING PROCEDURE MUST BE CONDUCTED BY A QUALIFIED HYDRAULIC TECHNICIAN. To test the pressure exerted at the shear blades, disconnect the shear from the power source. Remove the shear blades from the frame. Figure 2.3B 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 2.3B) 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. Hold the control lever down till the needle, on the pressure gauge, of the tester stops climbing. Figure 2.3C CAUTION: WHEN TESTING THE RAIL SHEAR, BE SURE TO FOLLOW ALL SAFETY GUIDELINES. 2.4 Hose Requirements It is not often necessary or advisable to use long hoses. All hoses must have an oil resistant inner surface and an abrasion resistant outer 6

7 surface. Each hose must have male pipe ends for most application. Longer hoses can be used when necessary, but can affect the operation of the engine due to resistance in the hose. If small diameter or long hoses are used, or if restrictive fittings are connected to the supply and return ports, the pressure required to push the fluid through the system and back to the tank will be higher. This will reduce tool power. *Important Oil should always flow from the male coupler through the female coupler. NOTE: The pressure increase in uncoupled hoses left in the sun may make them difficult to connect. When possible after use, connect the free ends of the operating hoses together. HOSE TYPES Hydraulic hose types authorized for use by PortaCo, Inc. is as follows: 1. Labeled and certified nonconductive 2. Wire braided (conductive) 3. Fabric braided (not certified or labeled non-conductive) Hose 1: Listed above is the only hose authorized for use near electrical conductors. Hoses 2 and 3: Listed above are conductive and must never be used near electrical conductors. HOSE PRESSURE RATING The rated working pressure of the hydraulic hose must be at least 175 bar (2500 psi).

10 3.0 Operating Instructions 3.1 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 closing rate of the shear blades, are limited to the industries standard and cannot be altered. When the control lever is release the blades automatically retract at a more rapid rate to reduce shearing time. 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. Hydraulic quick connect couplers are located at the rear of the tool to allow more convenient routing of the supply hoses. Fully guarded hydraulic plumbing protects the operator from accidental leakage of oil onto the welded area, reducing the potential for a fire. The G-18D55-53-W is a versatile power unit that can meet the needs for most hydraulic tools used by the rail road industry. This power unit is capable of powering two tools simultaneously at 5 GPM (20 LPM) or one tool a 10 GPM (40 LPM) all the flows are at 138 BAR (2000 PSI). The maximum pressure of the hydraulic system is limited to BAR (2150 PSI). The power source provided the required flow and pressure to operated HTMA type I LPM (4-6 GPM) and type RR LPM (9-10.5) tools. All which, are OPEN-CENTER tools required an operating pressure of 138 BAR (2000 PSI). 3.2 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. On the hydraulic system guard cover there is a CAUTION decal that specifies that the weld shear is rated for a flow of 10 GPM/40 LPM and pressure of 2000 PSI/150 BAR do not exceed these flow / pressure ratings.
