NOTE: . Plastic and materials that melt at low temperatures should be cut at low speeds. . Soft wood should be cut at high speed. . Aluminum, tin, and copper, lead, and zinc alloys may be cut at any speed, depending on the type of cutting being done. Use paraffin or other suitable lubricant on the cutter to prevent the cut material from adhering to the cutter teeth. WARNING: Wire brushes must never be operated at speeds higher than 15,000 RPM. Wire brushes must run at least one minute before use. During this period, no one should stand in front of or in line with the rotating brush. Failure to heed this warning could result in serious personal injury. SPEED DIAL SETTINGS Type of Accessory Soft Wood Hard Wood Laminates Plastics Steel Aluminum, Brass, Etc.

Learning to use the rotary tool: . Hold the tool in your hand and get used to its weight, balance, and the taper of the housing. This taper permits the tool to be grasped like a pencil. . Examine the rotary tool accessories carefully. Damaged accessories can fly apart as they come up to speed and should not be used. The use of damaged accessories can result in serious personal injury. . Practice on scrap materials first to see how the tool operates. Keep in mind that the work is done by the speed of the tool and by the accessory in the collet. You should not lean on or push the tool into the work. It is best to make a series of passes with the tool rather than attempt to do all the work in one pass. To make a cut, pass the tool back and forth over the work like you would a small paint brush. Cut a little material on each pass until you reach the desired depth. For most work, a gentle touch is best; you will have greater control, make fewer errors, and get the most efficient work out of the accessory. For the best control in close work, grip the tool like a pencil between your thumb and forefinger. A“handgrip” methodofholdingthetoolisusedforoperations such as grinding a flat surface or using cut-off discs. To operate the rotary tool: • Secure all work in a vise or clamp to a workbench to prevent it from moving under the tool. • 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. • Lower the tool gradually until the accessory contacts the workpiece. • Move the tool continuously at a steady, consistent pace. • 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. The weight of the tool alone is adequate for most jobs. ..Lift the tool away from the workpiece before turning off • the tool. Fig. 10 PENCIL HOLDING METHOD 16 OPERATION TELESCOPING TOOL HANGER WITH CLAMP ON BASE See Figure 11. The telescoping tool hanger provides a convenient place to hang the rotary tool while the flex shaft is in use. To clamp the base to a worktable: . Turn the clamp screw counterclockwise to open the clamping area. . Place clamp over edge of worktable. . Turn the clamp screw clockwise until the clamp is secure. To attach the tool hanger to the base: . Turn the lower part of the tool hanger clockwise to unlock. . Pull the tool hanger up to lengthen or push the tool hanger down to shorten its height. . Turn the lower part of the tool hanger counterclockwise to lock into place. . Screw the tool hanger into the top of the clamp. NOTE: When using the flex shaft, hang the rotary tool from the tool hanger hook using the hook located on the back of the rotary tool. CAUTION: To prevent damage to the spindle or spindle lock, always allow motor to come to a complete stop before engaging the spindle lock. OPERATING THE FLEX SHAFT See Figures 12 - 14. The 1/8 in. collet must be inserted into the rotary tool before the flex shaft can be installed. To install the flex shaft: . Unplug the rotary tool. . Loosen collet sleeve by turning counterclockwise and remove. . Press and hold the spindle lock, and rotate the shaft by hand until the spindle lock engages the shaft, preventing Fig. 12 Fig. 11 CUP END OF FLEX SHAFT COLLET SLEEVE CLAMP SCREW CLAMP-ON BASE TOOL HANGER FLEX SHAFT ROTARY TOOL HOOK TOOL HANGER HOOK COLLET NUT DRIVE SHAFT 1/8 in.
