USER MANUAL 400 XPR DREMEL

Read and understand all instructions. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

WORK AREA

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.

Electrical Safety

Double Insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double Insulation eliminates the need for the three wire grounded power cord and grounded power supply system. Before plugging in the tool, be certain the outlet voltage supplied is within the voltage marked on the nameplate. Do not use "AC only" rated tools with a DC power supply.

Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded. If operating the power tool in damp locations is unavoidable, a Ground Fault Circuit Interrupter must be used to supply the power to your tool. Electrician's rubber gloves and footwear will further enhance your personal safety.

Don't expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.

When operating a power tool outside, use an outdoor extension cord marked "W-A" or "W." These cords are rated for outdoor use and reduce the risk of electric shock.

Personal Safety

Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.

Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. Keep handles dry, clean and free from oil and grease.

Avoid accidental starting. Be sure switch is "OFF" before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch "ON" invites accidents.

Remove adjusting keys or wrenches before turning the tool ON. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.

Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.

Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

Tool Use and Care

Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.

Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.

Do not use tool if switch does not turn it ON or OFF. Any tool that cannot be controlled with the switch is dangerous and must be repaired.

Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.

Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.

Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control. Any alteration or modification is a misuse and may result in a dangerous condition.

Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools. Develop a periodic maintenance schedule for your tool.

Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.

Service

Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury. For example: internal wires may be misplaced or pinched, safety guard return springs may be improperly mounted.

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 electric shock or injury. Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.

SAFETY RULES FOR ROTARY TOOL

Accessories must be rated for at least the speed recommended on the tool warning label. Wheels and other accessories running over rated speed can fly apart and cause injury.

Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. If cutting into existing walls or other blind areas where electrical wiring may exist is unavoidable, disconnect all fuses or circuit breakers feeding this worksite.

Do not operate the flexible shaft with a sharp bend. Over bending the shaft can generate excessive heat on the jacket or hand piece. The recommended minimum is 6^ radius.

Always disconnect the power cord from the power source before making any adjustments or attaching any accessories. You may unexpectedly cause the tool to start leading to serious personal injury.

Be aware of the switch location, when placing the tool down or when picking the tool up. You may accidentally activate the switch.

Always hold the hand piece firmly in your hands during the start-up. The reaction torque of the motor, as it accelerates to full speed, can cause the shaft to twist.

Always wear safety goggles and dust mask. Use only in well ventilated area. Using personal safety devices and working in safe environment reduces risk of injury.

After changing the bits or making any adjustments, make sure the collet nut and any other adjustment devices are securely tightened. Loose adjustment device can unexpectedly shift, causing loss of control, loose rotating components will be violently thrown.

Do not reach in the area of the spinning bit. The proximity of the spinning bit to your hand may not always be obvious.

Allow brushes to run at operating speed for at least one minute before using wheel. During this time no one is to stand in front or in line with the brush. Loose bristles or wires will be discharged during the run-in time.

Wire and bristle brushes must never be operated at speeds greater than 15,000/min. Direct the discharge of the spinning wire brush away from you. Small particles and tiny wire fragments may be discharged at high velocity during the "cleaning" action with these brushes and may become imbedded in your skin. Bristles or wires will be discharged from the brush at high speeds.

Carefully handle both the tool and individual grinding wheels to avoid chipping or cracking. Install a new wheel if tool is

dropped while grinding. Do not use a wheel that may be damaged. Fragments from a wheel that bursts during operation will fly away at great velocity possibly striking you or bystanders.

Never use dull or damaged bits. Sharp bits must be handled with care. Damaged bits can snap during use. Dull bits require more force to push the tool, possibly causing the bit to break.

Use clamps to support workpiece whenever practical. Never hold a small workpiece in one hand and the tool in the other hand while in use. Allow for sufficient space, at least 6", between your hand and the spinning bit. Round material such as dowel rods, pipes or tubing have a tendency to roll while being cut, and may cause the bit to "bite" or jump toward you. Clamping a small workpiece allows you to use both hands to control the tool.

Inspect your workpiece before cutting. When cutting irregularly shaped workpieces, plan your work so it will not slip and pinch the bit and be torn from your hand. For example, if carving wood, make sure there are no nails or foreign objects in the workpiece. Nails or foreign objects can cause the bit to jump.

Never start the tool when the bit is engaged in the material. The bit cutting edge may grab the material causing loss of control of the cutter.

Avoid bouncing and snagging the wheel, especially when working corners, sharp edges etc. This can cause loss of control and kick-back.

The direction of feed with the bit into the material when carving, routing or cutting is very important. Always feed the bit into the material in the same direction as the cutting edge is exiting from the material (which is the same direction as the chips are thrown). Feeding the tool in the wrong direction, causes the cutting edge of the bit to climb out of the work and pull the tool in the direction of this feed.

If the workpiece or bit becomes jammed or bogged down, turn the tool "OFF" by the switch. Wait for all moving parts to stop and unplug the tool, then work to free the jammed material. If the switch to the tool is left "ON" the tool could restart unexpectedly causing serious personal injury.

Do not leave a running tool unattended, turn power off. Only when tool comes to a

complete stop it is safe to put it down.

Do not grind or sand near flammable materials. Sparks from the wheel could ignite these materials.

Do not touch the bit or collet after use. After use the bit and collet are too hot to be touched by bare hands.

Regularly clean the tool's air vents with compressed air. Excessive accumulation of powdered metal inside the motor housing may cause electrical failures.

Do not allow familiarity gained from frequent use of your rotary tool to become commonplace. Always remember that a careless fraction of a second is sufficient to inflict severe injury.

Do not alter or misuse tool. Any alteration or modification is a misuse and may result in serious personal injury.

This product is not intended for use as a dental drill, in human or veterinary medical applications. Serious injury may result.

When using the steel saws, cutoff wheels, high speed cutters or tungsten carbide cutters, always have the work securely clamped. Never attempt to hold the work with one hand while using any of these accessories. The reason is that these wheels will grab if they become slightly canted in the groove, and can kickback causing loss of control resulting in serious injury. Your second hand should be used to steady and guide the hand holding the tool. When a cutoff wheel grabs, the wheel itself usually breaks. When the steel saw, high speed cutters or tungsten carbide cutter grab, it may jump from the groove and you could lose control of the tool.

WARNING Some dust created by power drilling and other construction activities, contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

OPERATION

Learning To Use the Rotary Tool

Getting the most out of your rotary tool is a matter of learning how to let the speed and the feel of the tool in your hands work for you.

The first step in learning to use the rotary tool is to get the "feel" of it. Hold it in your hand and feel its weight and balance. Feel the taper of the

housing. This taper permits the tool to be grasped much like a pen or pencil. The unique comfort grip on the nose allows for added comfort and control during use.

Always hold the tool away from your face.

Accessories can be damaged during handling and can fly apart as they come up to speed. This is not common, but it does happen.

When holding tool, do not cover the air vents with

your hand. Blocking the air vents could cause the motor to overheat.

IMPORTANT! Practice on scrap material first to see how the tool's high-speed action performs. Keep in mind that your rotary tool will perform best by allowing the speed, along with the correct Dremel™ accessory and attachment, do the work for you. Do not put pressure on the tool during use, if possible.

Instead, lower the spinning accessory lightly to the work surface and allow it to touch the point at which you want to begin. Concentrate on guiding the tool over the work using very little pressure from your hand. Allow the accessory to do the work.

For best control in close work, grip the rotary tool like a pencil between your thumb and forefinger.

The "golf" grip method is used for more aggressive operations such as grinding or cutting.

Usually it is better to make a series of passes with the tool rather than to do the entire job with one pass. A gentle touch gives the best control and reduces the chance for error.

Operating Speeds

To achieve the best results when working with different materials, set the variable speed control to suit the job. To select the right speed for the accessory in use, practice with scrap material first.

NOTE: Speed is affected by voltage changes. A reduced incoming voltage will slow the RPM of the tool, especially at the lowest setting. If your tool appears to be running slowly, increase the speed setting accordingly. The tool may not start at the lowest switch setting in areas where outlet voltage is less than 120 volts. Simply move the speed setting to a higher position to begin operation.

The 400 Series XPR Rotary Tool switch settings are marked on the speed control dial. Refer to the Speed Settings chart on pages 11 thru 13 to help determine the proper speed for the material being worked on and the accessory to use.

Most jobs can be accomplished using the tool at the highest setting. However, certain materials (some plastics and metals) can be damaged by high-speed generated heat and should be worked on at relatively slow speeds.

Slow speed operation (15,000 RPM or less) is usually best for polishing operations employing the felt polishing accessories, delicate wood carving and fragile model parts. All brushing applications require lower speeds to avoid wire discharge from the holder. Let the performance of the tool do the work for you when using lower speed settings.

Higher speeds are better for drilling, carving, cutting, routing, shaping, cutting dadaes or rabbets in wood. Hardwoods, metals and glass require high speed operation also.

The settings for approximate RPM's are:

Switch Setting	Speed Range RPM
2	5,000-8,000
4	9,000-11,000
6	12,000-17,000
8	18,000-24,000
10	25,000-35,000

Set the Speed Control to the desired setting.

Some guidelines regarding tool speed:

• There is no accessory for the Dremel Rotary tool that will drill or cut glass.
• Plastic and other materials that melt at low temperatures should be cut at low speeds.
• Polishing, buffing and cleaning with a wire brush must be done at speeds not greater than 15,000 RPM to prevent damage to the brush and your material.
• Wood should be cut at high speed.
• Iron or steel should be cut at high speed.
• If a high speed steel cutter starts to vibrate, it usually indicates that it is running too slow.
• Aluminum, copper alloys, lead alloys, zinc alloys and tin may be cut at various speeds, depending on the type of cutting being done. Use a paraffin (not water) or other suitable lubricant on the cutter to prevent the cut material from adhering to the cutter teeth.

NOTE: Increasing pressure on the tool is not the answer when it is not performing properly. Try a different accessory or speed setting to achieve the desired result. Please refer to the following Speed Setting charts or simply contact Dremel Consumer Service at:

1-800-437-3635

or at www.Dremel.com.

WARNING

Preventative maintenance performed by unautho

rized personnel may result in misplacing of internal wires and components which could cause serious hazard. We recommend that all tool service be performed by a Dremel™ Service Facility.

WARNING

To avoid injury from unexpected starting or electri

cal shock, always remove plug from wall outlet before performing service or cleaning.

Carbon Brushes

The brushes in your tool have been engineered for many hours of dependable service.

To prepare the brushes for use, run the tool at full speed for 5 minutes under no load. This will properly "seat" the brushes, and extend the life of the tool.

To maintain peak efficiency of the motor, examine the brushes for wear every 40-50 hours.

CAUTION

Using the tool with worn brushes will permanently

damage the motor.

Use only original Dremel™ replacement brushes.

Inspect the rotary tool brushes after 40-50 hours of use. If the rotary tool runs erratically, loses power, or makes unusual noises check the brushes for wear and possible replacement. Remember: brushes in the rotary tool are similar to oil in a car; the more you check/service, the better the performance.

Follow these steps to check/change the rotary tool brushes.

1. With the power cord unplugged, place the tool on a clean surface. Use the tool wrench to pry up and release the clip on the brush cover (Figure A).
2. Remove the brushes from the tool by pulling the shunt and brass clip which are attached to the brush (Figure B).

NOTE: Be sure to note how the brass clip slides out of the slot next to the brush pocket. Also, note how the detent on brass clip fits into brush pocket slot, which secures the brass clip into proper position.

1. Check each brush for wear. If brush is less than 3/8 long, or if contact end is rough or pitted, replace the brush.

Removing Brush Cover

Removing/Inspecting Brushes

InstallingBrushes

For questions or replacement brushes, please call Dremel's Consumer Service at 1-800-437-3635

or check our website at www.Dremel.com.

1. Install existing or new brushes so the curved surface of the brush end matches the curvature of the motor commutator (as seen through the brush opening).

NOTE: The detent on the brass clip must fit into the slot on the side of the brush pocket, which secures the brass clip in the proper position (Figure C).

1. Reinstall brush covers by angling the non-clip end into the opening. Make certain brush spring is centered in the "V" notch on the brush, then snap closed the clip end of the brush cover.
2. Plug power cord into a wall outlet. Run the rotary tool at full speed for 5 minutes under no load. This will properly seat the brushes and extend the life of the tool.

Cleaning The Tool

Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through openings.

The tool may be cleaned with compressed air. Always wear safety goggles when cleaning tool with compressed air.

There is no need to lubricate the Dremel™ rotary tool.

CAUTION

Certain cleaning agents and solvents will damage

plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.

Clean the "soft grip" areas of the tool using a damp cloth. Tougher soiled areas may require more than one wipe application to get clean.

ACCESSORIES

For availability of all accessories and attachments, refer your local hardware, hobby or home center. Or contact Dremel Consumer Service at:1-800-437-3635 or at www.Dremel.com.

WARNING

1/8" shank

Aluminum Oxide Grinding Stones (red/brown)

These grinding stones come round, pointed or flat and are made of aluminum

oxide. Use them for every possible grinding operation: sharpening lawn mower blades, screwdriver tips, knives, scissors, chisels and other cutting tools. Use to remove flash from metal castings, deburring any kind of metal. These grinding stones can be resharpened with a dressing stone. In machine shops, high speed drills and cutters are normally ground with aluminum oxide wheels.

1/8" shank

Silicon Carbide Grinding Stones (blue/green)

Tougher than aluminum oxide points, these are made especially for use on hard materials such as glass and ceramics.

Diamond Wheel Points

Used for fine detail work on wood, jade, ceramic, glass and other hard material. Bits are covered with diamond particles.

1/8" shank

3/32" shank

ACCESSIONS (continued)

High Speed Cutters

High speed cutters are used in carving, cutting and slotting wood, plastics

and soft metals (such as aluminum, copper and brass). Made of high quality steel.

1/8" shank

Structured Tooth Tungsten Carbide Cutters

1/8" shank

These cutters feature fast cutting needlesharp teeth for greater material removal with minimum loading. Use on fiberglass, wood, plastic, epoxy and rubber.

Engraving Cutters

Engraving cutters come in a wide variety of sizes and

3/32" shank

shapes and are used for intricate work on ceramics (greenware), wood carvings, jewelry and scrimshaw. They are often used in making complicated printed circuit boards. They should not be used on steel and very hard materials, but are good for use on wood, plastic and soft metals.

Tungsten Carbide Cutters

1/8" shank

Tungsten carbide cutters are long-lived cutters for use on hardened steel, fired

ceramics and other very hard materials. They can be used for engraving on tools and garden equipment.

Wire Brushes

CAUTION

Never use wire brushes at speeds greater than

15,000 rpm. Refer to Speed Settings (pages 10-12) for proper tool and setting.

Three different shapes of wire brushes are available in three different materials: stainless steel, brass and carbon wire. Stainless steel

1/8" shank

brushes perform well on pewter, aluminum, stainless steel and other metals, without leaving rust. Brass brushes are non-sparking and softer than steel, making them good for use on soft metals like gold, copper and brass. Carbon wire brushes are good for general purpose cleaning.

Bristle Brushes

1/8" shank

Bristle brushes are used for cleaning tools on

silverware, jewelry and antiques. The three shapes make it possible to get into tight corners and other difficult spaces. They can be used with polishing compound for faster cleaning or polishing.

Brushing Pressure

• The tips of a wire brush do the work. Operate the brush with the lightest pressure so only the tips of the wires come in contact with the work surface.
• If heavier pressure is used, the wires will become overstressed, resulting in a wiping action. If this continues, the life of the brush will be shortened by fatigue.
• Apply the brush to the work surface so the majority of the brush face makes full contact. Applying the edge or side of the brush to the work surface will result in wire breakage and shortened brush life.

CORRECT:

Wire tips doing the work.

INCORRECT:

Excessive pressure can cause wire breakage.

Aluminum Oxide Abrasive Wheels

Used to remove paint, deburr metal, polish stainless steel and other metals. Available in medium grit.

1/8" shank

Grinding Wheel

Used for deburring, removing rust, and general purpose grinding. Use with Mandrel #402.

ACCESSIONS (continued)

Sanding Accessories

Sanding discs in fine, medium and coarse grades are made to fit mandrel #402. They can be

used for nearly any small sanding job from model making to fine furniture finishing.

In addition, the drum sander makes it possible to shape wood, smooth fiberglass, sand inside curves and other difficult places. Drum bands are replaceable and come in fine and coarse grades.

1/8" shank

Flapwheels grind and polish flat or contoured surfaces. They are used most effectively as a finishing sander, after heavier surface sanding and material removal is completed. Flapwheels come in fine and coarse grades.

Buffers are a great finishing accessory for cleaning and light sanding. They work effectively on metal, glass, wood, aluminum and plastics. Buffs are available in medium and coarse grades.
