Craftsman 50347 Operator's Manual

Note: Inspect before each use for evidence of fluid leaks, damaged hydraulic fittings, bent or broken attach-ments and missing parts.1. Locate and close release valve by turning it clockwise until firmly closed. (Do not over tighten)2. Operate by pumping handle. This will send fluid from the pump reservoir into the high pressure hose assemblyand into the ram assembly.3. Continue pumping until ram reaches desired height.Note: Pump may be used in horizontal and vertical position as illustrated (See figure 2).OPERATIONTo Release Pressure on work piece:Slowly, carefully turn the release valve counterclockwise until ram retracts to desired position. Never turnrelease valve more than 1/2 full turn. The ram return system is spring loaded, allowing controlled retractionof the ram.Figure 2 - Horizontal and Vertical PositionMAINTENANCEImportant: Use only a good grade hydraulic oil. We recommend Mobil DTE13M. Avoid mixing different types offluid and Never use brake fluid, turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can causefailure of the pump and the potential for sudden and immediate loss of load.Adding oil1. With ram fully lowered, set pump unit in its normal, level position. Locate and remove oil filler screw (seeFigure 1).2. Fill until oil is within 3/8" (6 mm) of the hole opening, reinstall oil filler screw.Changing oilFor best performance and increased system life, replace the complete fluid supply at least once per year.1. With ram fully lowered, remove the oil filler screw from the pump reservoir as above.2. Lay the pump on its side and drain the fluid into a suitable container.Note: Dispose of hydraulic fluid in accordance with local regulations.3. Set pump in its level upright position.4. Fill with good quality hydraulic oil to within 3/8" of the oil filler screw hole opening. Reinstall oil filler screw.LubricationA periodic coating of light lubricating oil to pivot points and hinges will help to prevent rust and assure that pumpassemblies move freely.CleaningPeriodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with anoily cloth.Note: Never use sandpaper or abrasive material on these surfaces !StorageWhen not in use, store with the pump piston and ram fully retracted.© Sears, Roebuck and Co.6
