COLLET NUT — To loosen, first press shaft lock button and rotate the shaft by hand until the lock engages the shaft preventing further rotation. Your Dremel 4000 is equipped with a quick collet lock mechanism. This mechanism engages the output shaft in 12 separate locations on the shaft for easier operation.

	Do not engage lock while
! CAUTION
	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 illustration), 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.

! CAUTION	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.

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. Retighten 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, snap it back into place so it will be out of the way while the tool is in use.
