COLLET NUT — 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 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, finger tighten

the collet nut until the accessory shank is gripped by

the collet. Avoid excessive tightening of the collet

nut when there is no bit inserted.

COLLETS — Four different size collets (see illus-

tration), 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: Some rotary tool kits may not include all four

collets sizes.

BALANCING ACCESSORIES — For precision work, it

is important that all accessories be in good balance

(much the same as the tires on your automobile). To

true up or balance an accessory, slightly loosen collet

nut and give the accessory or collet a 1/4 turn. Re-

tighten collet nut and run the Rotary Tool. You should

be able to tell by the sound and feel if your accessory

is running in balance. Continue adjusting in this

fashion until best balance is achieved. To maintain

balance on abrasive wheel points, before each use,

with the wheel point secured in the collet, turn on the

Rotary Tool and run the 415 Dressing Stone lightly

against the revolving wheel point. This removes high

spots and trues up the wheel point for good balance.

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, remove it from the tool and snap

it back into place underneath the cord so it will be out

of the way while the tool is in use.

DREMEL KEYLESS CHUCK

Use only with black chuck #4486.

Other chucks may not allow

accessory bit to be tightened fully.

The keyless chuck holds various accessories with

shank sizes 1/32" to 1/8" and is intended for light duty

accessories such as drill bits, sanding drums,

polishing accessories, wire and bristle brushes and

cut-off wheels. The keyless chuck allows you to

change accessories frequently, quickly and easily.

There are some applications which can generate high

forces on the bit or if you are unable to generate

finger tightening pressure sufficient to secure the bit

you must use the supplied wrench to assist in

securing the bit.

Attaching the Keyless Chuck and Accessory Bit

Read and understand the manual

for use of the keyless chuck with

the tool. Insert and securely tighten the shank of the

accessory well within the jaws of the chuck. If an

accessory is not properly gripped within the jaws of a

Always unplug Rotary Tool before
changing accessories, changing

collets or servicing your Rotary Tool.
