Main Parts of Benchtop Grinder Reference 1 2 3 4 5 6 Subassembly Grinding Base Power Switch Rest Grinding Wheel Eye Shield Guard Assembly Instructions ⚠WARNING Remove the benchtop grinder from the carton and examine it carefully. Do no dispose of carton or any packaging material until all parts are examined. To avoid injury, ALWAYS turn the tool off and disconnect the grinder from the power outlet before installing or changing the grinding wheel.
Installing the Spark Guards and Eye Shield Brackets Install the spark guards to the wheel guards of your grinder as shown in Fig. 2. Adjust them to within 1/16 in. of the grinding wheel or other accessory being used. Note: There is a left and right spark guard. Refer to Fig. 2 to ensure that you install them correctly. Installing the Eye Shields Note: There is a left and a right eye shield mounting rod. Fig. 3 is for the right wheel guard as you face the front of the tool. Carefully examine Fig.
Tip: The eye shields are identical and will fit properly on either side of the grinder; however, it may be necessary to loosen the center hex nut in order to slip the shield over the mounting rod. After you have assembled and installed each eye shield mounting rod to the grinder, attach the eye shields to the rods as shown in Fig. 5. Install them in such a way that the three hex nuts on each eye shield are on the back side, away from the operator, when the grinder is in use.
Ring Testing and Installing Grinding Wheels 1. Suspend the wheel on the arbor but do not tighten the spindle nut. 2. Imagine a vertical line up the center of the wheel. With a hard plastic or wood object, tap the wheel at 45 degrees on each side of the vertical line, 1” – 2” from the wheel’s edge. 3. Rotate the wheel 180 degrees and repeat the tapping test. 4. If the wheel rings with a clear tone, the wheel is safe and may be installed.
Operating Instructions ⚠WARNING Always wear eye protection. Only use accessories rated at least equal to the maximum speed marked on the tool. Do not modify the tool in any way.
