[. . . ] 0. 54 kg Press and hold the spindle lock, and rotate the shaft with the provided collet wrench until the spindle lock engages the shaft, preventing further rotation. With the spindle lock engaged, use the collet wrench to loosen the collet nut, if necessary. Remove the collet nut and old collet using collet wrench, if necessary. OPERATION WARNING Do not allow familiarity with products to make you careless. Remember that a careless fraction of a second is sufficient to inflict serious injury. Insert the unslotted end of the collet in the hole in the end of the tool shaft. Replace the collet nut on the shaft. WARNING Always use the collet which matches the shank size of the accessory you plan to use. The accessory should fit smoothly into the collet, but you should be able to tighten the accessory firmly and securely with the provided wrench. WARNING Always wear eye protection marked to comply with ANSI Z87. 1. Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury. WARNING Do not use any attachments or accessories not recommended by the manufacturer of this product. The use of attachments or accessories not recommended can result in serious personal injury. DANGER If you are changing an accessory immediately after use, be careful not to touch the collet, collet nut, or the accessory with your hands or fingers. Always use the wrench provided. 3 English INSTALLING ACCESSORIES See Figures 4 - 5. Press and hold the spindle lock, and rotate the shaft by hand until the spindle lock engages the shaft, preventing further rotation. You should be able to tell by the sound and feel if the accessory is running in balance. Continue adjusting in this fashion until the best balance is achieved. To select the right speed for each job, use a practice piece of material. Vary speed to find the best speed for the accessory you are using and the job to be done. Use the indicator mark above the speed control dial to set the best speed for the job. For example, a speed setting of 1 is approximately 10, 000 RPM, and a speed setting of MAX is approximately 35, 000 RPM. Refer to the speed dial settings table to determine the proper speed based on the material being worked and the type of accessory being used. SLOWER SPEEDS Certain materials, some plastics for example, require a relatively slow speed because the friction of the tool generates heat and causes the plastic to melt at high speed. Slow speeds (15, 000 RPM or less) are usually best for polishing operations using the polishing accessories. They may also be best for working on delicate projects, delicate wood carving, and fragile model parts. To determine the optimum operational speed for different 4 English materials and accessories, refer to the speed dial settings table. The best way to determine the correct speed for work on any material is to practice for a few minutes on a piece of scrap, even after referring to the table. [. . . ] Hold the tool in front and away from you, keeping the tool accessory clear of the workpiece. Turn on the tool and let the motor and accessory build up to full speed. Use just enough pressure to keep the tool from chattering or bouncing. NOTE: Heavy pressure will decrease the tool's speed and put a strain on the motor. [. . . ]
