REV 07g;08j Operation Turning the Bench Grinder ON and OFF Speed Control and On/Off Knob (31) 1. Insert the Plug (36) into an electrical outlet. Turn the speed control Knob (31) 2. clockwise to turn the motor ON and adjust its speed. To turn OFF, turn the Knob counter3. clockwise until it clicks. Do not leave the bench grinder run4. ning unattended. Turn off the tool when not in use. Grinding with the Grinding Wheel WARNING: The grinding wheel can fly apart and cause injury. Grinding wheels must always be checked for cracks or imperfections. This is done with the “ring test”. Tap the wheel gently near the outer rim with the handle of a screwdriver. You should hear a clear bell-like ring. If a dull thud occurs, do not use the wheel. The wheel may be damaged and could come apart during operation. Bring the workpiece into the wheel 1. gently, without jarring. When grinding high speed steels 2. such as drill and tool bits, avoid high temperature buildup as this can affect the temper of the steel. For small workpieces such as drill 3. bits or chisels, avoid applying pressure to the wheel at a high angle that could cause the workpiece to become lodged between the tool rest and the wheel. Grinding with the Flex Shaft Flex Shaft (32) Wheel Cover (14) (37) 1. Secure the Flex Shaft (32) to the Wheel Cover (14). Align and insert the shaft. It can only go in one way. Tighten the Flex Shaft Connector Nut 2. (37) over the Wheel Cover. Slip off the Chuck Cover (49).3. Loosen the Fixing Nut (47) with the 4. Wrench (50). Insert the Mounted Stone Bit (48) into 5. the Chuck (46) and tighten Fixing Nut. Slip the Chuck Cover (49) over the 6. Chuck assembly. Grasp the Flex Shaft handle with one 7. hand, and turn the Grinder ON with the other hand. CAUTION: Wear ANSI-approved safety glasses when grinding. When finished, turn the Grinder OFF 8. and wait for it to stop before setting down the Flex Shaft. Maintenance Dressing the Grinding Wheel Note: New wheels frequently are not true and during operation will often become grooved, glazed (build up), out of round, or misshapen. You will need a grinding wheel dresser for this operation. Dressers are available from Harbor Freight Tools. Stand to the side of the wheel for this 1. operation. If the wheel is new let it run for a 2. minute with no load. If the wheel runs straight and true, you will not need to dress it prior to operation. If it does not, proceed with the following instructions. If you are using a “pistol grip” dresser, 3. grip the handle firmly with one hand and the arm of the dresser with the other. Allow the wheel to reach full speed. Use the tool rest to support your hand and the dresser, and evenly apply the dresser to all surfaces of the wheel. The wheel can be dressed in a few minutes. If you are using an “inline” dresser, 4. hold the handle firmly, put the dresser on the tool rest so that its wheels can move freely (i.e., the exposed part of the wheel should be facing up). Let the wheel reach full speed and apply the dresser evenly to all surfaces.
