SAFETY WARNINGS

!

WARNING

READ ALL SAFETY WARNINGS AND

ALL INSTRUCTIONS

Failure to follow the warnings and instructions may result in

electric shock, re 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

a. Keep work area clean and well lit. Cluttered or dark

areas invite accidents.

b. Do not operate power tools in explosive

atmospheres, such as in the presence of ammable

liquids, gases or dust. Power tools create sparks

which may ignite the dust or fumes.

c. Keep children and bystanders away while operating

a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

a. 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.

Unmodied plugs and matching outlets will reduce risk

of electric shock.

b. 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.

c. Do not expose power tools to rain or wet

conditions. Water entering a power tool will increase

the risk of electric shock.

d. 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.

e. 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.

f. If operating a power tool in a damp location is

unavoidable, use a residual current device (RCD)

protected supply. Use of an RCD reduces the risk of

electric shock.

PERSONAL SAFETY

a. 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 inuence of drugs, alcohol or medication. A

moment of inattention while operating power tools may

result in serious personal injury.

b. 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.

c. Prevent unintentional starting. Ensure the switch

is in the off-position before connecting to power

source and/or battery pack, picking up or carrying

the tool. Carrying power tools with your nger on the

switch or energising power tools that have the switch

on invites accidents.

d. Remove any adjusting key or wrench before

turning the power tool on. A wrench or a key left

attached to a rotating part of the power tool may result

in personal injury.

e. Do not overreach. Keep proper footing and balance

at all times. This enables better control of the power

tool in unexpected situations.

f. Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing and gloves away

from moving parts. Loose clothes, jewellery or long

hair can be caught in moving parts.

g. If devices are provided for the connection of dust

extraction and collection facilities, ensure these are

connected and properly used. Use of dust collection

can reduce dust-related hazards.

POWER TOOL USE AND CARE

a. Do not force the power tool. Use the correct power

tool for your application. The correct power tool will

do the job better and safer at the rate for which it was

designed.

b. Do not use the power tool if the switch does not

turn it on and off. Any power tool that cannot be

controlled with the switch is dangerous and must be

repaired.

c. Disconnect the plug from the power source and/or

the battery pack from the power tool before making

any adjustments, changing accessories, or storing

power tools. Such preventive safety measures reduce

the risk of starting the power tool accidentally.

d. Store idle power tools out of the reach of children

and do not allow persons unfamiliar with the power

tool or these instructions to operate the power tool.

Power tools are dangerous in the hands of untrained

users.

e. Maintain power tools. Check for misalignment or

binding of moving parts, breakage of parts and any

other condition that may affect the power tool’s

operation. If damaged, have the power tool repaired

before use. Many accidents are caused by poorly

maintained power tools.

f. Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges are

less likely to bind and are easier to control.

g. Use the power tool, accessories and tool bits etc.

in accordance with these instructions, taking into

account the working conditions and the work to

be performed. Use of the power tool for operations

different from those intended could result in a

hazardous situation.

SERVICE

a. Have your power tool serviced by a qualied repair

person using only identical replacement parts.

This will ensure that the safety of the power tool is

maintained.

SAFETY INSTRUCTIONS FOR

ALL OPERATIONS

SAFETY WARNINGS COMMON FOR GRINDING,

SANDING, WIRE BRUSHING, POLISHING, CARVING OR

ABRASIVE CUTTING-OFF OPERATIONS

a. This power tool is intended to function as a grinder,

sander, wire brush, polisher, carving or cut-off tool.

Read all safety warnings, instructions, illustrations

and specications provided with this power tool.

Failure to follow all instructions listed below may result

in electric shock, re and/or serious injury.

b. Do not use accessories which are not specically

designed and recommended by the tool

manufacturer. Just because the accessory can be

attached to your power tool, it does not assure safe

operation.

c. The rated speed of the grinding accessories must

be at least equal to the maximum speed marked on

the power tool. Grinding accessories running faster

than their rated speed can break and y apart.

d. The outside diameter and the thickness of your

accessory must be within the capacity rating of

your power tool. Incorrectly sized accessories cannot

be adequately controlled.

e. The arbour size of wheels, sanding drums or any

other accessory must properly t the spindle or

collet of the power tool. Accessories that do not

match the mounting hardware of the power tool will run

out of balance, vibrate excessively and may cause loss

of control.

f. Mandrel mounted wheels, sanding drums, cutters

or other accessories must be fully inserted into

the collet or chuck. If the mandrel is insufciently

held and/or the overhang of the wheel is too long, the

mounted wheel may become loose and be ejected at

high velocity.

g. Do not use a damaged accessory. Before each use

inspect the accessory such as abrasive wheels for

chips and cracks, sanding drum for cracks, tear or

excess wear, wire brush for loose or cracked wires.

If power tool or accessory is dropped, inspect for

damage or install an undamaged accessory. After

inspecting and installing an accessory, position

yourself and bystanders away from the plane of

the rotating accessory and run the power tool at

maximum no-load speed for one minute. Damaged

accessories will normally break apart during this test time.

h. Wear personal protective equipment. Depending

on application, use face shield, safety goggles or

safety glasses. As appropriate, wear dust mask,

hearing protectors, gloves and workshop apron

capable of stopping small abrasive or workpiece

fragments. The eye protection must be capable of

stopping ying debris generated by various operations.

The dust mask or respirator must be capable of

ltrating particles generated by your operation.

Prolonged exposure to high intensity noise may cause

hearing loss.

i. Keep bystanders a safe distance away from work

area. Anyone entering the work area must wear

personal protective equipment. Fragments of

workpiece or of a broken accessory may y away and

cause injury beyond immediate area of operation.

j. Hold power tool by insulated gripping surfaces

only, when performing an operation where the

cutting accessory may contact hidden wiring or its

own cord. Cutting accessory contacting a “live” wire

may make exposed metal parts of the power tool “live”

and could give the operator an electric shock.

k. Always hold the tool rmly in your hand(s) during

the start-up. The reaction torque of the motor, as it

accelerates to full speed, can cause the tool to twist.

l. 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.

Clamping a small workpiece allows you to use your

hand(s) to control the tool. Round material such as

dowel rods, pipes or tubing have a tendency to roll

while being cut, and may cause the bit to bind or jump

toward you.

m. Position the cord clear of the spinning accessory.

If you lose control, the cord may be cut or snagged

and your hand or arm may be pulled into the spinning

accessory.

n. Never lay the power tool down until the accessory

has come to a complete stop. The spinning

accessory may grab the surface and pull the power

tool out of your control.

o. After changing the bits or making any adjustments,

make sure the collet nut, chuck or any other

adjustment devices are securely tightened. Loose

adjustment devices can unexpectedly shift, causing

loss of control, loose rotating components will be

violently thrown.

p. Do not run the power tool while carrying it at your

side. Accidental contact with the spinning accessory

could snag your clothing, pulling the accessory into

your body.

q. Regularly clean the power tool’s air vents. The

motor’s fan will draw the dust inside the housing and

excessive accumulation of powdered metal may cause

electrical hazards.

r. Do not operate the power tool near ammable

materials. Sparks could ignite these materials.

s. Do not use accessories that require liquid coolants.

Using water or other liquid coolants may result in

electrocution or shock.

KICKBACK AND RELATED WARNINGS

Kickback is a sudden reaction to a pinched or snagged

rotating wheel, sanding band, brush or any other

accessory. Pinching or snagging causes rapid stalling

of the rotating accessory which in turn causes the

uncontrolled power tool to be forced in the direction

opposite of the accessory’s rotation.

For example, if an abrasive wheel is snagged or pinched

by the workpiece, the edge of the wheel that is entering

into the pinch point can dig into the surface of the material

causing the wheel to climb out or kick out. The wheel may

either jump toward or away from the operator, depending on

direction of the wheel’s movement at the point of pinching.

Abrasive wheels may also break under these conditions.

Kickback is the result of power tool misuse and/or incorrect

operating procedures or conditions and can be avoided by

taking proper precautions as given below.

a. Maintain a rm grip on the power tool and position

your body and arm to allow you to resist kickback

forces. The operator can control kickback forces, if

proper precautions are taken.

b. Use special care when working corners, sharp

edges etc. Avoid bouncing and snagging the

accessory. Corners, sharp edges or bouncing have

a tendency to snag the rotating accessory and cause

loss of control or kickback.

c. Do not attach a toothed saw blade. Such blades

create frequent kickback and loss of control.

d. 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.

18

e. When using rotary les, cut-off wheels, high-speed

cutters or tungsten carbide cutters, always have

the work securely clamped. These wheels will grab

if they become slightly canted in the groove, and can

kickback. When a cut-off wheel grabs, the wheel itself

usually breaks. When a rotary le, high-speed cutter

or tungsten carbide cutter grabs, it may jump from the

groove and you could lose control of the tool.

SAFETY WARNINGS SPECIFIC FOR GRINDING AND

ABRASIVE CUTTING-OFF OPERATIONS

a. Use only wheel types that are recommended

for your power tool and only for recommended

applications. For example: do not grind with the

side of a cut-off wheel. Abrasive cut-off wheels are

intended for peripheral grinding, side forces applied to

these wheels may cause them to shatter.

b. For threaded abrasive cones and plugs use only

undamaged wheel mandrels with an unrelieved

shoulder ange that are of correct size and length.

Proper mandrels will reduce the possibility of breakage.

c. Do not “jam” a cut-off wheel or apply excessive

pressure. Do not attempt to make an excessive

depth of cut. Overstressing the wheel increases the

loading and susceptibility to twisting or snagging of

the wheel in the cut and the possibility of kickback or

wheel breakage.

d. Do not position your hand in line with and behind

the rotating wheel. When the wheel, at the point of

operation, is moving away from your hand, the possible

kickback may propel the spinning wheel and the power

tool directly at you.

e. When wheel is pinched, snagged or when

interrupting a cut for any reason, switch off the

power tool and hold the power tool motionless until

the wheel comes to a complete stop. Never attempt

to remove the cut-off wheel from the cut while the

wheel is in motion otherwise kickback may occur.

Investigate and take corrective action to eliminate the

cause of wheel pinching or snagging.

f. Do not restart the cutting operation in the

workpiece. Let the wheel reach full speed and

carefully re-enter the cut. The wheel may bind, walk

up or kickback if the power tool is restarted in the

workpiece.

g. Support panels or any oversized workpiece to

minimize the risk of wheel pinching and kickback.

Large workpieces tend to sag under their own weight.

Supports must be placed under the workpiece near the

line of cut and near the edge of the workpiece on both

sides of the wheel.

h. Use extra caution when making a “pocket cut” into

existing walls or other blind areas. The protruding

wheel may cut gas or water pipes, electrical wiring or

objects that can cause kickback.

SAFETY WARNINGS SPECIFIC FOR

WIRE BRUSHING OPERATIONS

a. 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.

b. 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.

c. 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.

d. Do not exceed 15,000 RPM when using wire brushes

!

DO NOT WORK WITH MATERIALS CONTAINING

ASBESTOS (asbestos is considered carcinogenic)

!

TAKE PROTECTIVE MEASURES WHEN DURING

WORK DUST CAN DEVELOP THAT IS HARMFUL TO

ONE’S HEALTH, COMBUSTIBLE OR EXPLOSIVE (some

dusts are considered carcinogenic); wear a dust mask

and work with dust/chip extraction when connectable

DREMEL CHUCK 4486 (4300)

The Dremel chuck allows you to quickly and easily change

accessories on Dremel tools without changing collets.

Accepts accessories with 0.8 - 3.2 mm shank.

To loosen, rst press shaft lock button and rotate the shaft

by hand until it engages the shaft lock. Do not engage the

shaft lock while the tool is running.

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

ts between the jaws. Insert the new accessory into the

chuck far enough so that there is approximately 6 mm

between the end of the chuck and the beginning of the

working part of the accessory. 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 nd the accessory slipping in the chuck, use the

included EZ Twist 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 causing

the accessory to no longer run true and concentric

(run-out).

To reset the jaws, apply the following procedure:

1. Remove the accessory from the chuck.

2. Clean the chuck.

3. Press shaft lock button and tighten the chuck until

the jaws extend past the outer surface of the chuck,

approximately 3 mm.

4. Push the end of the chuck rmly against a hard at

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

runout. If there is obvious run-out, repeat the

procedure.

8. With the shaft lock engaged, tighten the chuck
