COLLET NUT— To loosen, first press shaft lock but- ton and rotate the collet nut by hand until the lock engages the shaft preventing further rotation.
! CAUTION | Do not engage lock while the | |
Tool is running. | ||
|
With the shaft lock engaged, loosen the collet nut by hand. 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 Cordless 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 col- let 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.
BALANCING ACCESSORIES — For precision work, it is important that all accessories be in good bal- ance (much the same as the tires on your automo- bile). 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 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.
Remember, your new Dremel Cordless Rotary Tool is the finest power tool of its kind. But its perfor- mance is only as good as the accessories with which it is used. We recommend only Dremel accessories be used. Use of any other accessories may create a hazard. We hope you’ll enjoy many years of trouble free pleasure from your Dremel Cordless Rotary Tool.
