Always unplug Rotary Tool
before changing accessories,
changing collets or servicing your Rotary
Tool.
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
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 avail able 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.
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, snap it
back into place so it will be out of the way while
the tool is in use.
