TABLE OF CONTENTS Introduction ..................................................................................................................................................................... 2 Warranty .......................................................................................................................................................................... 2 � General Safety Rules .......................................................................................................
GENERAL SAFETY RULES Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes. Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control. Avoid accidental starting. Be sure switch is off before plugging in.
GENERAL SAFETY RULES SERVICE When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of shock or injury. Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel may result in a risk of injury.
SYMBOLS Some of the following symbols may be used on this product . Please study them and learn their meaning. Proper interpretation of these symbols will allow you to operate the product better and safer.
SYMBOLS The following signal words and meanings are intended to explain the levels of risk associated with this product. SYMBOL SIGNAL MEANING DANGER: Indicates an imminently hazardous situation, which, if not avoided, will result in death or serious injury. WARNING: Indicates a potentially hazardous situation, which, if not avoided, could result in death or serious injury. CAUTION: Indicates a potentially hazardous situation, which, if not avoided, may result in minor or moderate injury.
ELECTRICAL DOUBLE INSULATION EXTENSION CORDS Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual threewire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded.

FEATURES KNOW YOUR ROTARY TOOL KIT FLEX SHAFT See Figure 1. The safe use of this product requires an understanding of the information on the product and in this operator’s manual as well as a knowledge of the project you are attempting. Before use of this product, familiarize yourself with all operating features and safety rules. A flexible shaft can be connected to the rotary tool for working in hard to reach areas and for better control during delicate work.
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. WARNING: Always wear safety goggles or safety glasses with side shields when operating power tools. Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury. ON ( I )/OFF ( O ) SWITCH WARNING: Do not use any attachments or accessories not recommended by the manufacturer of this product.

Wire Circle Brushes (nylon, brass, stainless steel) Nylon brush: removing dirt and dust 4 Wire Cup Brushes ( 3/16 in. nylon, 3/16 in. and 5/8 in. brass, 5/8 in.
OPERATION WARNING: SPINDLE LOCK 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 buildup from cutting. Always use the wrench provided. COLLET CAUTION: To prevent damage to the spindle or spindle lock, always allow motor to come to a complete stop before engaging the spindle lock. COLLET NUT Fig. 4 INSTALLING ACCESSORIES See Figures 4 - 5. Unplug the rotary tool.
OPERATION CAUTION: WASHER To prevent damage to the spindle or spindle lock, always allow motor to come to a complete stop before engaging the spindle lock. USING THE MANDRELS MANDREL SCREW CUT-OFF DISC MANDREL See Figures 6 - 8. Three types of mandrels have been included for use with this kit. The standard mandrel is used with the cut-off discs, grinding wheels, emery wheel, and cut-off wheels. The screw mandrel is used with the polishing wheels and polishing drum.
OPERATION BALANCING ACCESSORIES For precision work, it is important that all accessories be properly balanced. To balance an accessory, slightly loosen the collet nut and give the accessory or collet a 1/4 in. turn. 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. FIBERGLASS CUT-OFF WHEEL SELECTING THE RIGHT SPEED See Figure 9.
OPERATION NOTE: Plastic and materials that melt at low temperatures should be cut at low speeds. To determine the optimum operational speed for different materials and accessories, refer to the Speed Dial Settings table. Look this table over and become familiar with it. 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.
OPERATION OPERATING THE ROTARY TOOL See Figure 10. 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. PENCIL HOLDING METHOD 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.
OPERATION TELESCOPING TOOL HANGER WITH CLAMP ON BASE TOOL HANGER HOOK 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. ROTARY TOOL HOOK Place clamp over edge of worktable. Turn the clamp screw clockwise until the clamp is secure.
OPERATION To install accessories into the flex shaft: Unplug the rotary tool. HOLE Locate the hole behind the collet nut in the flex shaft body. LOCKING KEY COLLET NUT Turn the collet nut until the hole in the flex shaft body aligns with the hole visible inside the flex shaft. Insert provided locking key into the aligned holes to lock collet nut into place. Insert the shank of the accessory into the collet nut until the shank bottoms out, then pull it out 1/16 in.
OPERATION USING THE PLUNGE CUTTING ACCESSORY See Figures 15 - 16. The plunge cutting accessory attaches to the end of the rotary tool. Depth of cut can be adjusted in 1/8 in. increments up to 1 in. To assemble the plunge cutting accessory: Hold the cup-shaped accessory piece with the cup side facing down. COLLET SLEEVE Insert the cylinder-shaped accessory piece up through the cup-shaped piece. The legs of the cylinder-shaped piece should be facing down.
MAINTENANCE Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommended using this product for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the product using compressed air.
