Safety Symbols

The definitions below describe the level of severity for each signal word. Please read the manual and pay attention to these symbols.

This is the safety alert symbol. It is used to alert you to potential

! personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.

DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.

WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION, used with the safety alert symbol, indicates a hazardous situation which, if not avoided, will result in minor or moderate injury.

General Power Tool Safety Warnings

Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

Keep work area clean and well lit. Cluttered or 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 children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

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

2

Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of an GFCI reduces 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 a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

Safety Rules for Rotary Tools - (cont.)

The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.

Safety warnings specific for wire brushing operations:

Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin.

Allow brushes to run at operating speed for at least one minute before using them. 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.

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 use of these brushes and may become imbedded in your skin.

Additional Safety Warnings

Do not use router bit with the Dremel chuck.

Bit may become a projectile and cause serious injury.

GFCI and personal protection devices like electrician’s rubber gloves and footwear will further enhance your personal safety.

Do not use AC only rated tools with a DC power supply. While the tool may appear to work, the electrical components of the AC rated tool are likely to fail and create a hazard to the operator.

Keep handles dry, clean and free from oil and grease. Slippery hands cannot safely control the power tool.

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.

Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or safety guard return

springs may be improperly mounted.

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

Risk of injury to user. The power cord must only be serviced by a Dremel Service Facility..

Some dust created by power sanding, sawing, grinding, 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 chemicallytreated 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.

DREMEL CHUCK

Dremel Chuck allows you to quickly and easily change accessories on Dremel Rotary Tools without changing collets. Accepts accessories with 1/32” - 1/8” shank. To loosen, first press shaft lock button and rotate the shaft by hand until the lock engages the shaft preventing further rotation.

Do not engage lock running. while the Rotary Tool is

With the shaft lock engaged use the wrench or the EZ Twist Nose Cap to loosen the chuck and open the jaws. Remove the accessory from the chuck. If necessary, continue loosening the chuck so that the new accessory fits between the jaws. Insert the new accessory into the chuck far enough so that there is approximately 1/4” between the end of the chuck and the beginning of the working part of the accessory (drill bit flutes, sand paper, engraving end, etc.). With the shaft lock engaged, tighten the chuck using the EZ Twist Nose Cap or wrench to secure the accessory.

Helpful Tips when using the

Dremel Chuck

• The Dremel Chuck and the collet and collet nut system are interchangeable on this tool. While the chuck will provide you with the best experience for changing accessories, the collet and collet nut will provide a more precise accessory holding solution especially in heavier side load applications. If you will be using your rotary tool for routing, heavy wood or metal cutting, heavy sanding, or carving you will probably have a better experience using the collet and collet nut.

• The Dremel Chuck needs to be securely tightened in order to retain the accessory during use. If you find the accessory slipping in the chuck, use the included EZTwist Nose Cap or wrench to tighten the chuck around the bit. If further slippage persists, switch to using the collet and collet nut.

• The jaws of the chuck can become displaced if dropped, pried against, or filled with dust causing the accessory to no longer run true and concentric. This is often called run-out. To reset the jaws, apply the following procedure:

1. Remove the accessory from the chuck.

2. Clean the chuck if necessary using compressed air.

3. Press shaft lock button and tighten the chuck until the jaws extend past the outer surface of the chuck, approximately 1/8".

4. Push the end of the chuck firmly against a hard flat surface to be sure the jaws are all seated axially.

5. Continue to hand tighten the chuck until the jaws completely close.

6. Loosen the chuck, and reinsert a straight accessory.

7. Turn the tool by hand and observe if there is any run-out. If there is obvious run-out, repeat the procedure.

COLLETS

Four different size collets (see illus ration),t to accommodate different shank sizes, are available for your Rotary Tool. To install a different collet, remove the collet nut and remove the old collet. Insert the unslotted end of the collet in the hole in the end of the tool shaft. Replace collet nut on the shaft.

Always use the collet which matches the shank size of the accessory you plan to use. Never

force a larger diameter shank into a collet. Note: Most rotary tool kits do not include all four collets sizes.

IDENTIFICATION

RINGS

Dremel 4300 is equipped with a quick shaft lock mechanism. This mechanism engages the output shaft in 8 separate locations on the shaft for easier operation.Do not engage lock while the Rotary Tool is running.

With the shaft lock engaged use the collet wrench to loosen the collet nut if necessary. The collet nut must be loosely threaded on when inserting an accessory. Change accessories by inserting the new one into the collet as far as possible to minimize runout and unbalance. With the shaft lock engaged, use collet wrench or EZ Twist Nose Cap to securely tighten the collet nut. (Fig. 5). Avoid excessive tightening of the collet nut when there is no bit inserted.

	FIxING STUCK COLLETS
	It is possible for a collet to get stuck within the
	collet nut especially if a collet nut is tightened
	onto the tool without a bit in place. If this
	happens, the collet can be removed from the
	collet nut by pushing the shank of an accessory
	into the hole in the collet nut. This should cause
	the collet to pop out of the collet nut.

For most work, the gentle touch is best. With it, you have the best control, are less likely to make errors, and will get the most effi cient work out of the accessory.

TOOL HANGER

The hanger is provided for the use of hanging your tool while using the Flex Shaft or for storage. If you do not use the hanger, snap it back into place so it will be out of the way while the tool is in use (Fig. 1).

Operating Speeds

To select the right speed for each job, use a practice piece of material.

NOTE: Speed is affected by voltage changes. A reduced incoming voltage will slow the RPM of the tool.

SLIDE "ON/OFF" SWITCH

The tool is switched "ON" by the slide switch located on the topside of the motor housing. TO TURN THE TOOL "ON", slide the switch button forward.

TO TURN THE TOOL "OFF", slide the switch button backward.

HIGH PERFORMANCE MOTOR

Your tool is equipped with a high performance rotary tool motor. This motor expands the versatility of the rotary tool by driving additional attachments such as the Dremel Right Angle Attachment and Dremel Flex Shaft.

ELECTRONIC FEEDBACK

Your tool is equipped with an internal electronic feedback system that provides a “soft start”, which will reduce the stresses that occur from a high torque start. The system also helps to keep the preselected speed virtually constant between no-load and load conditions.

VARIABLE SPEED DIAL

Your tool is equipped with a variable speed dial. The speed may be adjusted during operation by presetting the dial on or between any one of the settings.

You can refer to the charts on pages 27–30 to determine the proper speed, based on the material being worked and the type of accessory being used. These charts enable you to select both the correct acces sory and the optimum speed at a glance.

The speed of Rotary Tool is controlled by setting this dial on the housing (Fig. 9).

35	33,000-35,000 RPM
* Wire Brush Setting.

Needs for Slower Speeds

Certain materials, however, (some plastics and precious metals, for ex ample) require a relatively slow speed because at high speed the friction of the accessory generates heat and may cause damage to the material.

Slow speeds (15,000 RPM or less) usually are best for polishing operations employing the felt polishing ac ces sories. They may also be best for working on deli cate projects as “eggery” work, delicate wood carving and fragile model parts. (All brushing applications require lower speeds to avoid wire discharge from the holder.)

Higher speeds are better for carving, cutting, routing, shaping, cutting dadoes or rabbets in wood.

Hardwoods, metals and glass require high speed operation, and drilling should also be done at high speeds.

The point to remember is this: Many applications and accessories in our line will provide the best performance at full speed, but for certain materials, applications, and accessories, you need slower speeds, which is the reason our variable speed models are available.

Maintenance Information

To aid you in determining the optimum operational speed for differ ent materials and different accessories, we have constructed a series of tables that appear on pages 27–30. By referring to these tables, you can discover the recommended speeds for each type of accessory. Look these tables over and become familiar with them.

Ultimately, 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 chart. You can quickly learn that a slower or faster speed is more effective just by observing what hap pens as you make a pass or two at different speeds. When working with plastic, for example, start at a slow rate of speed and increase the speed until you observe that the plastic is melting at the point of contact. Then reduce the speed slight yl to get the optimum working speed.

Some rules of thumb in regard to speed:

1. Plastic and other materials that melt at low temperatures should be cut at low speeds.

2. Polishing, buffing and cleaning with any type of bristle brush must be done at speeds not greater than 15,000 RPM to prevent damage to the brush.

3. Wood should be cut at high speed.

4. Iron or steel should be cut at high speed. If a high speed steel cutter starts to chatter — this normally means it is running too slow.

5. Aluminum, copper alloys, lead alloys, zinc alloys and tin may be cut at various speeds, 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.

Increasing the pressure on the tool is not the answer when it is not performing as you think it should. Perhaps you should be using a different accessory, and perhaps an adjustment in speed would solve the problem. Leaning on the tool does not help.

Let speed do the work!

Use only Dremel®, high-performance accessories.

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

In order to prepare your brushes for use, run your tool at full speed for 5 minutes under no load. This will properly “seat” your brushes, which extends the life of both your brushes and your tool.

To maintain peak efficiency of the motor, we recommend every 40 - 50 hours the brush es be examined. Only genuine Dremel replacement brushes specially designed for your tool should be used.

MAINTENANCE OF REPLACEABLE

BRUSHES ON MODEL 4300

The brushes should be inspected frequently when tools are used continuously. If your tool runs spo rad ically, loses power, makes unusual noises or runs at a reduced speed, check the brushes.To continue using the

tool in this condition will permanently damage your tool.

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 as a screwdriver to remove the brush caps in a counter-clockwise direction (Fig. 10).

17

2. Remove the brushes from the tool by

pulling on the spring that is attached to the

carbon brush. If the brush is less than 1/8"

long and the end surface of the brush that

contacts the commutator is rough and/or

pitted, they should be replaced. Check

both brushes (Fig. 11).

Dremel Accessories

Use only Dremel®, high-performance accessories. Other accessories are not designed for this tool and may lead to personal injury or property damage.

Store accessories in a dry and temperate environment to avoid corrosion and deterioration.

The number and variety of accessories for the Rotary Tool are almost limitless. There is a category suited to almost any job you might have to do and a variety of sizes and shapes within each category which en ables you to get the perfect accessory for every need.

COLLETS

If you expect to use a variety of accessories, we recommend that in the beginning you purchase a complete set of four collets. Store these so that you will have the proper size of collet for any accessory or drill bit you want to use. Currently, the 1/8", 3/32",1/32" and

1/16" collets accommodate all of the available Dremel accessories. 1/8" collets are included in most rotary tool kits.

MANDRELS

A mandrel is a shank with a threaded or screw head, which are required when you use polishing accessories, cutting wheels, sanding discs, and pol ish ing points. The reason mandrels are used is that sanding discs, cutting wheels and similar accesso ries must be replaced frequently. The mandrel is a permanent shank, allowing you to replace only the worn head when necessary, thus saving the expense of replacing the shaft each time.

Screw Mandrel No 401

This is a screw mandrel used with the felt polishing tip and felt polishing wheels. 1/8" shank.

Small Screw Mandrel No 402

This is a mandrel with a small screw at its tip, and is used with emery and fiberglass cutting wheels, sanding discs and polishing wheels. 1/8" shank.

EZ Lock Mandrel No 402

The Dremel EZ Lock makes accessory changes easy as PULL - TWIST - RELEASE. The one-piece mandrel design simplifies the process of changing cutting wheels, buffs and detail abrasive brushes (EZ Lock compatible accessories).

EZ Drum™ Mandrel No EZ407SA

The Dremel EZ Drum makes accessory changes easy as PULL - INSERT - PRESS DOWN. The one-piece mandrel design simplifies the process of changing sanding bands.

High Speed Cutters

Available in many shapes, high speed cutters are used in carving, cutting and slotting in wood, plastics and soft metals such as aluminum, copper and brass. These are the accessories to use for freehand routing or carving in wood or plastic, and for precision cutting. Made of high quality steel. 1/8" shank.

Tungsten Carbide Cutters

These are tough, long-lived cutters for use on hard ened steel, fired ceramics and other very hard ma terials. They can be used for engraving on tools and garden equipment. 1/8" shanks.

19

Dremel Accessories (Continued)

Engraving Cutters

This group has a wide variety of sizes and shapes, and are made for intricate work on ceramics (greenware), wood carvings, jewelry and scrimshaw. They often are used in making complicat ed printed circuit boards. They should not be used on steel and other very hard materials but are excellent on wood, plastic and soft metals. 1/8" shank.

Structured Tooth Tungsten Carbide Cutters

Fast cutting, needle-sharp teeth for greater material removal with minimum loading. Use on fiberglass, wood, plastic, epoxy and rubber. 1/8" shank.

Silicon Carbide Grinding Stones (blue/green)

Tougher than aluminum oxide points, these are made es pecially for use on hard materials such as glass and ce ramics. Typical uses might be the removal of stilt marks and excess glaze on ceramics and engraving on glass. 1/8" shank.

Diamond Wheel Points

Excellent for fine detail work on wood, jade, ceramic, glass and other hard material. Bits are covered with diamond particles. 1/8" shanks. (Not recommended for drilling)

Aluminum Oxide Grinding Stones (red/brown)

Round, pointed, flat — you name the shape and there is one available in this category. These are made of aluminum oxide and cover virtually every possible kind of grinding application. Use them for sharpening lawn mower blades, screwdriver tips, knives, scissors, chisels and other cutting tools. Use to remove flash from metal castings, deburring any metal after cutting, smoothing welded joints, grinding off rivets and re mov ngi rust. These grinding stones can be resharped with a dressing stone. In machine shops, high speed drills and cut erst normally are ground with aluminum oxide wheels. 1/8" shank.

Wire Brushes

Maximum operating speed 15,000/min. Allow brush to run at 15,000/min for one minute

before use. Refer to Operating Speeds section for proper tool speed setting.

Three different shapes of wire brushes are available. The three shapes come in three different materials: stainless steel, brass and carbon wire. The stainless steel perform well on pewter, aluminum, stainless steel, and other metals, without leaving "after-rust". Brass brushes are non sparking, and softer than steel; making them good for use on soft metal like gold, cooper and brass. The carbon wire brushes are good for general purpose cleaning.

20

Dremel Accessories (Continued)

Bristle Brushes

These are excellent cleaning tools on silverware, jew elry and antiques. The three shapes make it possible to get into tight corners and other difficult places. Bristle brushes can be used with polishing compound for faster cleaning or polishing.

INCORRECT:

Excessive pressure can cause wire breakage.

CORRECT: Wire tips doing the work.

Brushing Pressure

1. Remember, the tips of a wire brush do the work. Operate the brush with the lightest pressure so only the tips of the wire come in contact with the work.

2. If heavier pressures are used, the wires will be overstressed, resulting in a wiping action; and if this is continued, the life of the brush will be shortened due to wire fatigue.

3. Apply the brush to the work in such a way that as much of the brush face as possible is in full contact with the work. Applying the side or edge of the brush to the work will result in wire breakage and shortened brush life.

Polishing Accessories

These include an impregnated polishing point and an impregnated polishing wheel for bringing metal sur faces to smooth finish; a felt polishing tip and felt polish ngi wheel, and cloth polishing wheel, all used for polishing plastics, metals, jewelry and small parts. Also included in this group is a polishing compound (No. 421) for use with the felt and cloth polishers.

Polishing points make a very smooth surface, but a high luster is obtained using felt or cloth wheels and polishing compound.

For best results polishing accessories should be used at speeds not greater than 15,000 RPM.

No polishing compound is needed when using the 425 Polishing Wheel.

Aluminum Oxide Abrasive Wheels

Use to remove paint, deburr metal, polish stainless steel and other metals. Available in medium grit. 1/8" shank.

Sanding Accessories

Sanding discs in fine, medium and coarse grades are made to fit mandrel No. 402 and EZ407. They can be used for nearly any small sanding job you might have, from model making to fine furniture finish ngi. In addition, there is the drum sander, a tiny drum which fits into the Rotary Tool and makes it possible to shape wood, smooth fiberglass, sand inside curves and other diffi -

21

Dremel Accessories (Continued)

cult places, and other sanding jobs. You replace the sanding bands on the drum as they become worn and lose their grit. Bands come in fine medium and coarse grades. 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. Buffs are a great finishing accessory for cleaning and light sanding. They work effectively on metal, glass, wood, aluminum and plastics. Coarse and medium buffs are sold together. All buffs are sold individually.

Do not exceed 15,000 RPM in speed. 1/8" shank.

Grinding Wheel

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

Cutting Wheels

These thin discs of emery or fiberglass are used for slicing, cutting off and similar operations. Use them for cutting off frozen bolt heads and nuts, or to reslot a screw head which has become so damaged that the screwdriver won’t work in it. Fine for cutting BX cable, small rods, tubing, cable and cutting rectangular holes in sheet metal.

Drywall Cutting Bit

Gives you fast, clean cuts in drywall. Use with Dremel No 565/566 Cutting Guide attachment.

Tile Cutting Bit

Cuts ceramic wall tile, cement board, and plaster. Use with Dremel No 565/566 Cutting Guide attachment.

Spiral Cutting Bit

Before each use, check to make certain that all components are assembled to accessory

shank and that the drum is sufficiently expanded to secure the band during use. If sanding band is loose on the drum during operation it may “fly” off and strike you or bystanders.

24

EZ Lock™ Operating Instructions

EZ Lock™ Mandrel No. EZ402 has a spring loaded sleeve and is used with cutting wheels, abrasive buffs and polishing cloth.

Always make sure the rotary tool is “OFF” and disconnect the plug from the power

source or the battery pack from the tool before changing accessories. Such preventative safety measures reduce the risk of starting the power tool accidentally.

Always make sure accessory is properly seated on mandrel before use. Incorrect seating of accessory on mandrel may lead to personal injury or property damage.

To load accessory:

1. Place EZ Lock™ mandrel into collet as deep as possible and tighten collet nut. Note: There is a blue spacer that will bottom out on the collet nut, setting the mandrel to the correct depth. When using with Dremel chuck, back the mandrel out slightly before tightening.

2. Pull spring-loaded sleeve DOWN towards tool with one hand and hold. You can brace the tool on the body or work-bench for extra leverage (Fig. 1).

3. With the other hand, align bowtie shape on cut-off wheel with mandrel and make sure metal insert is facing away from the tool (Fig. 2).

4. Place wheel on the mandrel to a point just below the bowtie on the mandrel and twist 90 degrees until the bowtie shape on the wheel aligns with the sleeve. Release sleeve. Wheel should lock in place (Fig. 3).

5. When mounting sanding and polishing accessories, align bowtie with metal insert on bottom of accessory (Fig. 4 & 5).

To check for proper seating, hold shaft lock button and twist accessory. Accessory will not be able to rotate on mandrel. To unload accessory:

1. Pull spring-loaded sleeve DOWN toward tool with one hand (Fig. 1).

2. Hold sleeve down while twisting accessory
