Anleitung Zusammenfassung
Do not wipe them with such solvent. Wipe plastic parts with a soft cloth lightly dampened with soapy water. 25. Consult an authorized Service Agent in the event of power tool failure. 26. Use only genuine HITACHI replacement parts. 27.This tool should only be disassembled for replacement of carbon brushes. PRECAUTIONS ON USING DISC GRINDER 1. This product shall be applied to industrial use. 2. Never operate these power tools without Wheel Guards. 3. Use only grinding wheels with a “Safe Speed” at least as high as the “No-Load Speed” indicated on the power tool nameplate. 4. Always hold the body handle and side handle of the power tools firmly. Otherwise the counterforce produced may result in inaccurate and even dangerous operation. 5. Never depress the push button while the spindle is turning.

STANDARD ACCESSORIES (1) Depressed center wheel .......................................... 1 (2) Wrench ........................................................................ 1 (3) Side Handle ............................................................... 1 Standard accessories are subject to change without notice. APPLICATIONS . Removal of casting fin and finishing of various types of steel, bronze and aluminum materials and castings. . Grinding of welded sections or sections cut by means of an acetylene torch. . Grinding of synthetic resins, slate, brick, marble, etc. . Cutting of synthetic concrete, stone, brick, marble, and similar materials. PRIOR TO OPERATION 1. Power source Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate. 2. Power switch Ensure that the power switch is in the OFF position. If the plug is connected to a power receptacle while the power switch is in the ON position, the power tool will start operating immediately, inviting serious accident. 3. Extension cord When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable. 4. Fitting and adjusting the wheel guard The wheel guard is a protective device to prevent injury should the depressed center wheel be shattered during operation. Ensure that the wheel guard is properly fitted and fastened before commencing grinding operation. [How to attach and adjusts the wheel guard] (Fig. 2) . Set the wheel ass’y to the packing gland. . Tighten M5 screw to secure the wheel guard while the lever is in closed position. . Perform the adjustment of the wheel guard while the lever is released. (Loosen M5 screw and readjust if the wheel guard does not rotate smoothly . . After adjustment, if machine operation is required, perform the operation only after setting the lever in closed position. . Lubricate the sliding section of the set piece (B) and the lever if the lever does not move smoothly. 5. Ensure that the depressed center wheel to be utilized is the correct type and free of cracks or surface defects. Also ensure that the depressed center wheel is properly mounted and the wheel nut is securely tightened. Refer to the section on “ASSEMBLING AND DISASSEMBLING THE DEPRESSED CENTER WHEEL”. 6. Conducting a trial run Before commencing grinding operation, the machine should be given a trial run in a safe area to ensure that it is properly assembled and that the depressed center wheel is free from obvious defects. Recommended trial run durations are as follows: After replacing depressed center wheel ……… 3 minutes or more Prior to starting routine work ……… 1 minute or more 7. Confirm the spindle lock mechanism. Confirm that the spindle lock is disengaged by pushing push button two or three times before switching the power too on. (See Fig. 1) 8. Fixing the side handle Screw the side handle into the gear cover. PRACTICAL GRINDER APPLICATION 1. Pressure: To prolong the life of the grinder and ensure a first class finish, it is important that the grinder should not be overloaded by applying too much pressure. In most applications, the weight of the grinder alone is sufficient for effective grinding. Too much pressure will result in reduced rotation speed, inferior surface finish, and overloading which could reduce the lift of the grinder. 2. Grinding angle Do not apply the entire surface of the depressed center wheel to the material to be ground. As shown in Fig. 3, the grinder should be held at an angle of 15°–30° so that the external edge of the grinding wheel contacts the workpiece at an optimum angle. 3. To prevent a new grinding wheel from digging into the workpiece, initial grinding should be performed English by drawing the grinder across the workpiece toward the operato...
