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. You will get burned because of the heat build-up from cutting. 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. Replace accessories if they become damaged or unbalanced. The rotary tool has a speed range of 10, 000 to 35, 000 RPM. 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. The speed control dial is numbered 1 to 5 and MAX. 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. Higher speeds are better for carving, cutting, and shaping wood. Hardwoods, metals, and glass require high speed operation. Drilling should also be done at high speeds. [. . . ] Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc. WARNING Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc. , come in contact with plastic parts. They contain chemicals that can damage, weaken or destroy plastic. [. . . ]
