Model W1839 & W1840 (For Machines Mfd. Since 3/16) SAFETY Additional Safety for Benchtop Grinders Serious injury or death can occur from impact injuries if a grinding wheel breaks apart during operation. Rotating grinding wheels can easily remove skin or cause entanglement injuries if clothing or apparel is caught in moving parts. Fingers can be pinched/cut by in-running pinch points. Flying sparks can ignite explosive or flammable materials.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) ELECTRICAL Circuit Requirements This machine must be connected to the correct size and type of power supply circuit, or fire or electrical damage may occur. Read through this section to determine if an adequate power supply circuit is available. If a correct circuit is not available, a qualified electrician MUST install one before you can connect the machine to power.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) Grounding Requirements ELECTRICAL This machine MUST be grounded. In the event of certain types of malfunctions or breakdowns, grounding provides a path of least resistance for electric current to travel—in order to reduce the risk of electric shock. Improper connection of the equipment-grounding wire will increase the risk of electric shock. The wire with green insulation (with/without yellow stripes) is the equipmentgrounding wire.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) SETUP Unpacking This machine has been carefully packaged for safe transportation. If you notice the machine has been damaged during shipping, please contact your authorized Shop Fox dealer immediately. Items Needed for Setup The following items are needed, but not included, to set up your machine.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) Inventory The following is a list of items shipped with your machine. Before beginning setup, lay these items out and inventory them. SUFFOCATION HAZARD! Immediately discard all plastic bags and packing materials to eliminate choking/suffocation hazards for children and animals. SETUP Note: If you cannot find an item on this list, carefully check around/inside the machine and packaging materials.

Some workbenches may require additional reinforcement to support the weight of the machine and workpiece materials.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) Assembly Before beginning the assembly process, refer to Items. Needed.for.Setup and gather everything you need. Ensure all parts have been properly cleaned of any heavy-duty rust-preventative applied at the factory (if applicable). Be sure to complete all steps in the assembly procedure prior to performing the Test.Run. Safety Shield Mounting Plate Safety Shield Safety Shield Mounting Bracket Flange Nuts To assemble machine, do these steps: 1.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) 6. Attach each tool rest assembly to grinder using (4) M8-1.25 x 12 hex bolts and (4) 8mm flat washers (see Figure 13). Some grinding wheels must be replaced before spark deflector or tool rest reach their final adjustment. As diameter of a grinding wheel is reduced, so is surface speed. Grinding under these conditions can lead to faster abrasive loss and poor grinding results. Always follow wheel manufacturer's directions. xx 44 Figure 13.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) Test Run Once assembly is complete, test run the machine to ensure it is properly connected to power and safety components are functioning properly. If you find an unusual problem during the test run, immediately stop the machine, disconnect it from power, and fix the problem BEFORE operating the machine again. The Troubleshooting table in the SERVICE section of this manual can help. Serious. injury. or. death. can. result. from. using. this. machine.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) OPERATIONS Operation Overview This machine will perform many types of operations that are beyond the scope of this manual. Many of these operations can be dangerous or deadly if performed incorrectly. The instructions in this section are written with the understanding that the operator has the necessary knowledge and skills to operate this machine. If at any time you are experiencing difficulties performing any operation, stop using the machine! To.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) Workpiece Inspection Wheel Selection Some workpieces are not suitable for grinding on a bench grinder. Before grinding, inspect all workpieces for the following: The Model W1839 only accepts Type-1 wheels with a 1⁄2" bore. The W1840 only accepts Type-1 wheels with a 5⁄8" bore. • Hard Workpiece: Workpieces that are made of stone, carbide, stainless steel, ceramics, glass, or have hardened welds will wear out most general-grade grinding wheels quickly.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) Wheel Inspection Before mounting a new grinding wheel, it must be inspected. Do not assume that a wheel is in sound condition just because it is new—often, damage can occur in shipping, with age, or with exposure to moisture. First, do a Visual Inspection. Look for any cracks, chips, nicks, or dents in the surface of the wheel. If you see any of these, DO NOT use the wheel.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) Wheel Care When grinding, your safety depends, to a large degree, on the condition of the wheel. A wheel in poor condition could break apart during rotation and injure the operator and others in the area. OPERATIONS Here are some tips to help you avoid breaking the wheel: • Always transport, store and handle wheels with care. Wheels may be damaged if they are dropped or if heavy objects are stacked on them.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) Wheel Dressing Depending on the type of grinding you do, the grinding wheel may require periodic dressing. There are several different types of wheel dressing devices available on the market (see Accessories on Page 25 for examples). Dressing restores the abrasive quality of the wheel surface and brings the wheel edge back to square. Always adjust the tool rest and spark deflector after dressing or replacing the grinding wheel.
Model W1839 & W1840 (For Machines Mfd. Since 3/16) Wheel Removal & Installation To remove and install grinding wheel, do these steps: 1. DISCONNECT MACHINE FROM POWER! 2. Remove outer guard by removing (3) knob bolts, (3) 6mm lock washers, and (3) 6mm flat washers that secure outer guard (see Figure 18). 3. Remove M16-2 hex nut (see Figure 19). Tip: Hold grinding wheel with free hand to stop it from turning while loosening the hex nut. Outer Guard Figure 18.
